+Pixman coding style.
+====================
+
+The pixman coding style is close to cairo's with one exception: braces
+go on their own line, rather than on the line of the if/while/for:
+
+ if (condition)
+ {
+ do_something();
+ do_something_else();
+ }
+
+not
+
+ if (condition) {
+ do_something();
+ do_something_else();
+ }
+
+
+
+Indentation
+===========
+
+Each new level is indented four spaces:
+
+ if (condition)
+ do_something();
+
+This may be achieved with space characters or with a combination of
+tab characters and space characters. Tab characters are interpreted as
+
+ Advance to the next column which is a multiple of 8.
+
+
+Names
+=====
+
+In all names, words are separated with underscores. Do not use
+CamelCase for any names.
+
+Macros have ALL_CAPITAL_NAMES
+
+Type names are in lower case and end with "_t". For example
+pixman_image_t.
+
+Labels, functions and variables have lower case names.
+
+
+Braces
+======
+
+Braces always go on their own line:
+
+ if (condition)
+ {
+ do_this ();
+ do_that ();
+ }
+ else
+ {
+ do_the_other ();
+ }
+
+Rules for braces and substatements of if/while/for/do:
+
+* If a substatement spans multiple lines, then there must be braces
+ around it.
+
+* If the condition of an if/while/for spans multiple lines, then
+ braces must be used for the substatements.
+
+* If one substatement of an if statement has braces, then the other
+ must too.
+
+* Otherwise, don't add braces.
+
+
+Comments
+========
+
+For comments either like this:
+
+ /* One line comment */
+
+or like this:
+
+ /* This is a multi-line comment
+ *
+ * It extends over multiple lines
+ */
+
+Generally comments should say things that aren't clear from the code
+itself. If too many comments say obvious things, then people will just
+stop reading all comments, including the good ones.
+
+
+Whitespace
+==========
+
+* Put a single space after commas
+
+* Put spaces around arithmetic operators such a +, -, *, /:
+
+ y * stride + x
+
+ x / unit_x
+
+* Do not put spaces after the address-of operator, the * when used as
+ a pointer derefernce or the ! and ~ operators:
+
+ &foo;
+
+ ~0x00000000
+
+ !condition
+
+ *result = 100
+
+* Break up long lines (> ~80 characters) and use whitespace to align
+ things nicely. This is one way:
+
+ some_very_long_function name (
+ implementation, op, src, mask, dest,
+ src_x, src_y, mask_x, mask_y, dest_x, dest_y,
+ width, height);
+
+ This is another:
+
+ some_very_long_function_name (implementation, op,
+ src, mask, dest,
+ src_x, src_y,
+ mask_x, mask_y,
+ dest_x, dest_y,
+ width, height);
+
+* Separate logically distinct chunks with a single newline. This
+ obviously applies between functions, but also applies within a
+ function or block or structure definition.
+
+* Use a newline after a block of variable declarations.
+
+* Use a single space before a left parenthesis, except where the
+ standard will not allow it, (eg. when defining a parameterized macro).
+
+* Don't eliminate newlines just because things would still fit on one
+ line. This breaks the expected visual structure of the code making
+ it much harder to read and understand:
+
+ if (condition) foo (); else bar (); /* Yuck! */
+
+
+Function Definitions
+====================
+
+Function definitions should take the following form:
+
+ void
+ my_function (int argument)
+ {
+ do_my_things ();
+ }
+
+If all the parameters to a function fit naturally on one line, format
+them that way. Otherwise, put one argument on each line, adding
+whitespace so that the parameter names are aligned with each other.
+
+I.e., do either this:
+
+ void
+ short_arguments (const char *str, int x, int y, int z)
+ {
+ }
+
+or this:
+
+ void
+ long_arguments (const char *char_star_arg,
+ int int_arg,
+ double *double_star_arg,
+ double double_arg)
+ {
+ }
+
+
+Mode lines
+==========
+
+Given the rules above, what is the best way to simplify one's life as
+a code monkey? Get your editor to do most of the tedious work of
+beautifying your code!
+
+As a reward for reading this far, here are some mode lines for the more
+popular editors:
+/*
+ * vim:sw=4:sts=4:ts=8:tw=78:fo=tcroq:cindent:cino=\:0,(0
+ * vim:isk=a-z,A-Z,48-57,_,.,-,>

+ configure.ac: Check if the compiler supports GCC vector extensions
+
+ The Intel Compiler 14.0.0 claims version GCC 4.7.3 compatibility

+ test/utils.c: Make the stack unaligned only on 32 bit Windows
+
+ The call_test_function() contains some assembly that deliberately
+ causes the stack to be aligned to 32 bits rather than 128 bits on
+ x86-32. The intention is to catch bugs that surface when pixman is
+ called from code that only uses a 32 bit alignment.
+
+ However, recent versions of GCC apparently make the assumption (either
+ accidentally or deliberately) that that the incoming stack is aligned
+ to 128 bits, where older versions only seemed to make this assumption
+ when compiling with -msse2. This causes the vector code in the PRNG to
+ now segfault when called from call_test_function() on x86-32.
+
+ This patch fixes that by only making the stack unaligned on 32 bit
+ Windows, where it would definitely be incorrect for GCC to assume that
+ the incoming stack is aligned to 128 bits.
+
+ V2: Put "defined(...)" around __GNUC__

+ Fix pixman build with older GCC releases

+ The following patch fixes building pixman with older GCC releases
+ such as GCC 3.3 and older (OpenBSD; some older archs use GCC 3.3.6)
+ by changing the method of detecting the presence of __builtin_clz
+ to utilizing an autoconf check to determine its presence. Compilers
+ that pretend to be GCC, implement __builtin_clz and are already
+ utilizing the intrinsic include LLVM/Clang, Open64, EKOPath and

+
+ The functions pixman_composite_glyphs_no_mask() and

+
+ utils.c: On x86-32 unalign the stack before calling test_function
+
+ GCC when compiling with -msse2 and -mssse3 will assume that the stack
+ is aligned to 16 bytes even on x86-32 and accordingly issue movdqa
+ instructions for stack allocated variables.
+
+ But despite what GCC thinks, the standard ABI on x86-32 only requires
+ a 4-byte aligned stack. This is true at least on Windows, but there
+ also was (and maybe still is) Linux code in the wild that assumed
+ this. When such code calls into pixman and hits something compiled
+ with -msse2, we get a segfault from the unaligned movdqas.
+
+ Pixman has worked around this issue in the past with the gcc attribute
+ "force_align_arg_pointer" but the problem has resurfaced now in
+
+ https://bugs.freedesktop.org/show_bug.cgi?id=68300
+
+ because pixman_composite_glyphs() is missing this attribute.
+
+ This patch makes fuzzer_test_main() call the test_function through a
+ trampoline, which, on x86-32, has a bit of assembly that deliberately
+ avoids aligning the stack to 16 bytes as GCC normally expects. The
+ result is that glyph-test now crashes.
+
+ V2: Mark caller-save registers as clobbered, rather than using
+ noinline on the trampoline.

+ pixman-combine32: Make Color Dodge routine follow the math more closely
+
+ Change blend_color_dodge() to follow the math in the comment more

+
+ Note, the new code here is in some sense worse than the old code
+ because it can now underflow the unsigned variables when the source is
+ superluminescent and (as - s) is therefore negative. The old code was
+ careful to clamp to 0.
+
+ But for superluminescent variables we really need the ability for the
+ blend function to become negative, and so the solution the underflow
+ problem is to just use signed variables. The use of unsigned variables
+ is a general problem in all of the blend mode code that will have to
+ be solved later.
+
+ The CRC32 values in thread-test and blitters-test are updated to
+ account for the changes in output.

+ vmx: align destination to fix valgrind invalid memory writes
+
+ The SIMD optimized inner loops in the VMX/Altivec code are trying
+ to emulate unaligned accesses to the destination buffer. For each
+ 4 pixels (which fit into a 128-bit register) the current
+ implementation:
+ 1. first performs two aligned reads, which cover the needed data
+ 2. reshuffles bytes to get the needed data in a single vector register
+ 3. does all the necessary calculations
+ 4. reshuffles bytes back to their original location in two registers
+ 5. performs two aligned writes back to the destination buffer
+
+ Unfortunately in the case if the destination buffer is unaligned and
+ the width is a perfect multiple of 4 pixels, we may have some writes
+ crossing the boundaries of the destination buffer. In a multithreaded
+ environment this may potentially corrupt the data outside of the
+ destination buffer if it is concurrently read and written by some
+ other thread.
+
+ The valgrind report for blitters-test is full of:
+
+ ==23085== Invalid write of size 8

+
+ This patch addresses the problem by first aligning the destination
+ buffer at a 16 byte boundary in each combiner function. This trick
+ is borrowed from the pixman SSE2 code.
+
+ It allows to pass the new thread-test on PowerPC VMX/Altivec systems and
+ also resolves the "make check" failure reported for POWER7 hardware:

+ test: Add new thread-test program
+
+ This test program allocates an array of 16 * 7 uint32_ts and spawns 16
+ threads that each use 7 of the allocated uint32_ts as a destination
+ image for a large number of composite operations. Each thread then
+ computes and returns a checksum for the image. Finally, the main
+ thread computes a checksum of the checksums and verifies that it
+ matches expectations.
+
+ The purpose of this test is catch errors where memory outside images
+ is read and then written back. Such out-of-bounds accesses are broken
+ when multiple threads are involved, because the threads will race to
+ read and write the shared memory.
+
+ V2:
+ - Incorporate fixes from Siarhei for endianness and undefined behavior
+ regarding argument evaluation
+ - Make the images 7 pixels wide since the bug only happens when the
+ composite width is greater than 4.
+ - Compute a checksum of the checksums so that you don't have to
+ update 16 values if something changes.
+
+ V3: Remove stray dollar sign

+
+ ssse3: Add iterator for separable bilinear scaling
+
+ This new iterator uses the SSSE3 instructions pmaddubsw and pabsw to
+ implement a fast iterator for bilinear scaling.
+
+ There is a graph here recording the per-pixel time for various
+ bilinear scaling algorithms as reported by scaling-bench:
+
+ http://people.freedesktop.org/~sandmann/ssse3.v2/ssse3.v2.png
+
+ As the graph shows, this new iterator is clearly faster than the
+ existing C iterator, and when used with an SSE2 combiner, it is also
+ faster than the existing SSE2 fast paths for upscaling, though not for
+ downscaling.
+
+ Another graph:
+
+ http://people.freedesktop.org/~sandmann/ssse3.v2/movdqu.png
+
+ shows the difference between writing to iter->buffer with movdqa,
+ movdqu on an aligned buffer, and movdqu on a deliberately unaligned
+ buffer. Since the differences are very small, the patch here avoids
+ using movdqa because imposing alignment restrictions on iter->buffer
+ may interfere with other optimizations, such as writing directly to
+ the destination image.
+
+ The data was measured with scaling-bench on a Sandy Bridge Core
+ i3-2350M @ 2.3GHz and is available in this directory:
+
+ http://people.freedesktop.org/~sandmann/ssse3.v2/
+
+ where there is also a Gnumeric spreadsheet ssse3.v2.gnumeric
+ containing the per-pixel values and the graph.
+
+ V2:
+ - Use uintptr_t instead of unsigned long in the ALIGN macro
+ - Use _mm_storel_epi64 instead of _mm_cvtsi128_si64 as the latter form
+ is not available on x86-32.
+ - Use _mm_storeu_si128() instead of _mm_store_si128() to avoid
+ imposing alignment requirements on iter->buffer

+
+ sse2: faster bilinear scaling (pack 4 pixels to write with MOVDQA)
+
+ The loops are already unrolled, so it was just a matter of packing
+ 4 pixels into a single XMM register and doing aligned 128-bit
+ writes to memory via MOVDQA instructions for the SRC compositing
+ operator fast path. For the other fast paths, this XMM register
+ is also directly routed to further processing instead of doing
+ extra reshuffling. This replaces "8 PACKSSDW/PACKUSWB + 4 MOVD"
+ instructions with "3 PACKSSDW/PACKUSWB + 1 MOVDQA" per 4 pixels,
+ which results in a clear performance improvement.
+
+ There are also some other (less important) tweaks:
+
+ 1. Convert 'pixman_fixed_t' to 'intptr_t' before using it as an
+ index for addressing memory. The problem is that 'pixman_fixed_t'
+ is a 32-bit data type and it has to be extended to 64-bit
+ offsets, which needs extra instructions on 64-bit systems.
+
+ 2. Allow to recalculate the horizontal interpolation weights only
+ once per 4 pixels by treating the XMM register as four pairs
+ of 16-bit values. Each of these 16-bit/16-bit pairs can be
+ replicated to fill the whole 128-bit register by using PSHUFD
+ instructions. So we get "3 PADDW/PSRLW + 4 PSHUFD" instructions
+ per 4 pixels instead of "12 PADDW/PSRLW" per 4 pixels
+ (or "3 PADDW/PSRLW" per each pixel).
+
+ Now a good question is whether replacing "9 PADDW/PSRLW" with
+ "4 PSHUFD" is a favourable exchange. As it turns out, PSHUFD
+ instructions are very fast on new Intel processors (including
+ Atoms), but are rather slow on the first generation of Core2
+ (Merom) and on the other processors from that time or older.
+ A good instructions latency/throughput table, covering all the
+ relevant processors, can be found at:
+ http://www.agner.org/optimize/instruction_tables.pdf
+
+ Enabling this optimization is controlled by the PSHUFD_IS_FAST
+ define in "pixman-sse2.c".
+
+ 3. One use of PSHUFD instruction (_mm_shuffle_epi32 intrinsic) in
+ the older code has been also replaced by PUNPCKLQDQ equivalent
+ (_mm_unpacklo_epi64 intrinsic) in PSHUFD_IS_FAST=0 configuration.
+ The PUNPCKLQDQ instruction is usually faster on older processors,
+ but has some side effects (instead of fully overwriting the
+ destination register like PSHUFD does, it retains half of the
+ original value, which may inhibit some compiler optimizations).

+ to test, PSHUFD_IS_FAST=0 seems to be a reasonable default for SSE2 code
+ and old processors (until the runtime CPU features detection becomes
+ clever enough to recognize different microarchitectures).

+
+ Add an iterator that can fetch bilinearly scaled images
+
+ This new iterator works in a separable way; that is, for a destination
+ scaline, it scales the two involved source scanlines and then caches
+ them so that they can be reused for the next destination scanlines.
+
+ There are two versions of the code, one that uses 64 bit arithmetic,
+ and one that uses 32 bit arithmetic only. The latter version is
+ used on 32 bit systems, where it is expected to be faster.
+
+ This scheme saves a substantial amount of arithmetic for larger
+ scalings; the per-pixel times for various configurations as reported
+ by scaling-bench are graphed here:
+
+ http://people.freedesktop.org/~sandmann/separable.v2/v2.png
+
+ The "sse2" graph is current default on x86, "mmx" is with sse2
+ disabled, "old c" is with sse2 and mmx disabled. The "new 32" and "new
+ 64" graphs show times for the new code. As the graphs show, the 64 bit
+ version of the new code beats the "old c" for all scaling ratios.
+
+ The data was taken on a Sandy Bridge Core i3-2350M CPU @ 2.0 GHz
+ running in 64 bit mode.
+
+ The data used to generate the graph is available in this directory:
+
+ http://people.freedesktop.org/~sandmann/separable.v2/
+
+ There is also a Gnumeric spreadsheet v2.gnumeric containing the
+ per-pixel values and the graph.
+
+ V2:
+ - Add error message in the OOM/bad matrix case
+ - Save some shifts by storing the cached scanlines in AGBR order
+ - Special cased version that uses 32 bit arithmetic when sizeof(long) <= 4

+
+ In preparation for sharing all iterator initialization code from all

+ pixman_iter_info_t.
+
+ The existing src_iter_init and dest_iter_init functions are

+ iterator.
+
+ Unlike in the other implementations, the general_iter_init() function
+ stores its own get_scanline() and write_back() functions in the
+ iterator, so it relies on the initializer being called after
+ get_scanline and write_back being copied from the struct to the

+
+ noop: Keep information about iterators in an array of pixman_iter_info_t
+
+ Instead of having a nest of if statements, store the information about
+ iterators in a table of a new struct type, pixman_iter_info_t, and
+ then walk that table when initializing iterators.
+
+ The new struct contains a format, a set of image flags, and a set of
+ iter flags, plus a pixman_iter_get_scanline_t, a
+ pixman_iter_write_back_t, and a new function type
+ pixman_iter_initializer_t.
+
+ If the iterator matches an entry, it is first initialized with the
+ given get_scanline and write_back functions, and then the provided
+ iter_initializer (if present) is run. Running the iter_initializer
+ after setting get_scanline and write_back allows the initializer to
+ override those fields if it wishes.
+
+ The table contains both source and destination iterators,
+ distinguished based on the recently-added ITER_SRC and ITER_DEST;
+ similarly, wide iterators are recognized with the ITER_WIDE
+ flag. Having both source and destination iterators in the table means
+ the noop_src_iter_init() and noop_dest_iter_init() functions become
+ identical, so this patch factors out their code in a new function
+ noop_iter_init_common() that both calls.
+
+ The following patches in this series will change all the
+ implementations to use an iterator table, and then move the table
+ search code to pixman-implementation.c.

+
+ MIPS: DSPr2: Fix bug in over_n_8888_8888_ca/over_n_8888_0565_ca routines
+
+ After introducing new PRNG (pseudorandom number generator) a bug in two DSPr2
+ routines was revealed. Bug manifested by wrong calculation in composite and
+ glyph tests, which caused make check to fail for MIPS DSPr2 optimizations.
+
+ Bug was in the calculation of the:
+ *dst = over (src, *dst) when ma == 0xffffffff
+
+ In this case src was not negated and shifted right by 24 bits, it was only
+ negated. When implementing this routine in the first place, I missplaced those
+ shifts, which alowed me to combine code for over operation and:
+ UN8x4_MUL_UN8x4 (s, ma);
+ UN8x4_MUL_UN8 (ma, srca);
+ ma = ~ma;
+ UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s);
+ So I decided to rewrite that piece of code from scratch. I changed logic, so
+ now assembly code mimics code from pixman-fast-path.c but processes two pixels
+ at a time. This code should be easier to debug and maintain.
+
+ The bug was revealed in commit b31a6962. Errors were detected by composite
+ and glyph tests.

+ sse2: faster bilinear interpolation (get rid of XOR instruction)
+
+ The old code was calculating horizontal weights for right pixels
+ in the following way (for simplicity assume 8-bit interpolation
+ precision):
+
+ Start with "x = vx" and do increment "x += ux" after each pixel.
+ In this case right pixel weight for interpolation can be calculated
+ as "((x >> 8) ^ 0xFF) + 1", which is the same as "256 - (x >> 8)".
+
+ The new code instead:
+
+ Starts with "x = -(vx + 1)", performs increment "x += -ux" after
+ each pixel and calculates right weights as just "(x >> 8) + 1",
+ eliminating the need for XOR operation in the inner loop.
+
+ So we have one instruction less on the critical path. Benchmarks
+ with "lowlevel-blt-bench -b src_8888_8888" using GCC 4.7.2 on
+ x86-64 system and default optimizations:
+
+ Intel Core i7 860 (2.8GHz):
+ before: src_8888_8888 = L1: 291.37 L2: 288.58 M:285.38

+
+ test: larger 0xFF/0x00 filled clusters in random images for blitters-test
+
+ Current blitters-test program had difficulties detecting a bug in
+ over_n_8888_8888_ca implementation for MIPS DSPr2:
+
+ http://lists.freedesktop.org/archives/pixman/2013-March/002645.html
+
+ In order to hit the buggy code path, two consecutive mask values had
+ to be equal to 0xFFFFFFFF because of loop unrolling. The current
+ blitters-test generates random images in such a way that each byte
+ has 25% probability for having 0xFF value. Hence each 32-bit mask
+ value has ~0.4% probability for 0xFFFFFFFF. Because we are testing
+ many compositing operations with many pixels, encountering at least
+ one 0xFFFFFFFF mask value reasonably fast is not a problem. If a
+ bug related to 0xFFFFFFFF mask value is artificialy introduced into
+ over_n_8888_8888_ca generic C function, it gets detected on 675591
+ iteration in blitters-test (out of 2000000).
+
+ However two consecutive 0xFFFFFFFF mask values are much less likely
+ to be generated, so the bug was missed by blitters-test.
+
+ This patch addresses the problem by also randomly setting the 32-bit
+ values in images to either 0xFFFFFFFF or 0x00000000 (also with 25%
+ probability). It allows to have larger clusters of consecutive 0x00
+ or 0xFF bytes in images which may have special shortcuts for handling
+ them in unrolled or SIMD optimized code.

+
+ Improve precision of calculations in pixman-gradient-walker.c
+
+ The computations in pixman-gradient-walker.c currently take place at
+ very limited 8 bit precision which results in quite visible artefacts
+ in gradients. An example is the one produced by demos/linear-gradient
+ which currently looks like this:
+
+ http://i.imgur.com/kQbX8nd.png
+
+ With the changes in this commit, the gradient looks like this:
+
+ http://i.imgur.com/nUlyuKI.png
+
+ The images are also available here:
+
+ http://people.freedesktop.org/~sandmann/gradients/before.png
+ http://people.freedesktop.org/~sandmann/gradients/after.png
+
+ This patch computes pixels using floating point, but uses a faster
+ algorithm, which makes up for the loss of performance.
+
+ == Theory:
+
+ In both the new and the old algorithm, the various gradient
+ implementations compute a parameter x that indicates how far along the
+ gradient the current scanline is. The current algorithm has a cache of
+ the two color stops surrounding the last parameter; those are used in
+ a SIMD-within-register fashion in this way:
+
+ t1 = walker->left_rb * idist + walker->right_rb * dist;
+
+ where dist and idist are the distances to the left and right color
+ stops respectively normalized to the distance between the left and
+ right stops. The normalization (which involves a division) is captured
+ in another cached variable "stepper". The cached values are recomputed
+ whenever the parameter moves in between two different stops (called
+ "reset" in the implementation).
+
+ Because idist and dist are computed in 8 bits only, a lot of
+ information is lost, which is quite visible as the image linked above
+ shows.
+
+ The new algorithm caches more information in the following way. When
+ interpolating between stops, the formula to be used is this:
+
+ t = ((x - left) / (right - left));
+
+ result = lc * (1 - t) + rc * t;
+
+ where
+
+ - x is the parameter as computed by the main gradient code,
+ - left is the position of the left color stop,
+ - right is the position of the right color stop
+ - lc is the color of the left color stop
+ - rc is the color of the right color stop
+
+ That formula can also be written like this:
+
+ result
+ = lc * (1 - t) + rc * t;
+ = lc + (rc - lc) * t
+ = lc + (rc - lc) * ((x - left) / (right - left))
+ = (rc - lc) / (right - left) * x +
+ lc - (left * (rc - lc)) / (right - left)
+ = s * x + b
+
+ where
+
+ s = (rc - lc) / (right - left)
+
+ and
+
+ b = lc - left * (rc - lc) / (right - left)
+ = (lc * (right - left) - left * (rc - lc)) / (right - left)
+ = (lc * right - rc * left) / (right - left)
+
+ To summarize, setting w = (right - left):
+
+ s = (rc - lc) / w
+ b = (lc * right - rc * left) / w
+
+ r = s * x + b
+
+ Since s and b only depend on the two active stops, both can be cached
+ so that the computation only needs to do one multiplication and one
+ addition per pixel (followed by premultiplication of the alpha
+ channel). That is, seven multiplications in total, which is the same
+ number as the old SIMD-within-register implementation had.
+
+ == Implementation notes:
+
+ The new formula described above is implemented in single precision
+ floating point, and the eight divisions necessary to compute the
+ cached values are done by multiplication with the reciprocal of the
+ distance between the color stops.
+
+ The alpha values used in the cached computation are scaled by 255.0,
+ whereas the RGB values are kept in the [0, 1] interval. The ensures
+ that after premultiplication, all values will be in the [0, 255]
+ interval.
+
+ This scaling is done by first dividing all the all the channels by
+ 257, and then later on dividing the r, g, b channels by 255. It would
+ be more natural to do all this scaling in only one place, but
+ inexplicably, that results in a (substantial) slowdown on Sandy Bridge
+ with GCC v 4.7.
+
+ == Performance impact (median of three runs of radial-perf-test):
+
+ == Intel Sandy Bridge, Core i3 @ 1.2GHz
+
+ Before: 0.014553
+ After: 0.014410
+ Change: 1.0% faster
+
+ == AMD Barcelona @ 1.2 GHz
+
+ Before: 0.021735
+ After: 0.021328
+ Change: 1.9% faster
+
+ Ie., slightly faster, though conceivably there could be a negative
+ impact on machines with a bigger difference between integer and
+ floating point performance.
+
+ V2:
+
+ - Use 's' and 'b' in the variable names instead of 'm' and 'd'. This
+ way they match the explanation above
+
+ - Move variable declarations to the top of the function
+
+ - Remove unused stepper field
+
+ - Some formatting fixes
+
+ - Don't pointlessly include pixman-combine32.h
+
+ - Don't offset x for each pixel; go back to offsetting left_x and
+ right_x at reset time. The offsets cancel out in the formula above,
+ so there is no impact on the calcualations.

+ Fix to lowlevel-blt-bench
+
+ The source, mask and destination buffers are initialised to 0xCC just after
+ they are allocated. Between each benchmark, there are a pair of memcpys,
+ from the destination buffer to the source buffer and back again (there are
+ no explanatory comments, but presumably this is an effort to flush the
+ caches). However, it has an unintended consequence, which is to change the
+ contents of the buffers on entry to subsequent benchmarks. This means it is
+ not a fair test: for example, with over_n_8888 (featured in the following
+ patches) it reports L2 and even M tests as being faster than the L1 test,
+ because after the L1 test, the source buffer is filled with fully opaque
+ pixels, for which over_n_8888 has a shortcut.
+
+ The fix here is simply to reverse the order of the memcpys, so src and
+ destination are both filled with 0xCC on entry to all tests.

+ utils.c: Increase acceptable deviation to 0.0064 in pixel_checker_t
+
+ The check-formats programs reveals that the 8 bit pipeline cannot meet
+ the current 0.004 acceptable deviation specified in utils.c, so we
+ have to increase it. Some of the failing pixels were captured in
+ pixel-test, which with this commit now passes.
+
+ == a4r4g4b4 DISJOINT_XOR a8r8g8b8 ==
+
+ The DISJOINT_XOR operator applied to an a4r4g4b4 source pixel of
+ 0xd0c0 and a destination pixel of 0x5300ea00 results in the exact
+ value:
+
+ fa = (1 - da) / sa = (1 - 0x53 / 255.0) / (0xd / 15.0) = 0.7782
+ fb = (1 - sa) / da = (1 - 0xd / 15.0) / (0x53 / 255.0) = 0.4096
+
+ r = fa * (0xc / 15.0) + fb * (0xea / 255.0) = 0.99853
+
+ But when computing in 8 bits, we get:
+
+ fa8 = ((255 - 0x53) * 255 + 0xdd / 2) / 0xdd = 0xc6
+ fb8 = ((255 - 0xdd) * 255 + 0x53 / 3) / 0x53 = 0x68
+
+ r8 = (fa8 * 0xcc + 127) / 255 + (fb8 * 0xea + 127) / 255 = 0xfd
+
+ and
+
+ 0xfd / 255.0 = 0.9921568627450981
+
+ for a deviation of 0.00637118610187, which we then have to consider
+ acceptable given the current implementation.
+
+ By switching to computing the result with
+
+ r = (fa * s + fb * d + 127) / 255
+
+ rather than
+
+ r = (fa * s + 127) / 255 + (fb * d + 127) / 255
+
+ the deviation would be only 0.00244961747442, so at some point it may
+ be worth doing either this, or switching to floating point for
+ operators that involve divisions.
+
+ Note that the conversion from 4 bits to 8 bits does not cause any
+ error in this case because both rounding and bit replication produces
+ an exact result when the number of from-bits divide the number of
+ to-bits.
+
+ == a8r8g8b8 OVER r5g6b5 ==
+
+ When OVER compositing the a8r8g8b8 pixel 0x0f00c300 with the x14r6g6b6
+ pixel 0x03c0, the true floating point value of the resulting green
+ channel is:
+
+ 0xc3 / 255.0 + (1.0 - 0x0f / 255.0) * (0x0f / 63.0) = 0.9887955
+
+ but when compositing 8 bit values, where the 6-bit green channel is
+ converted to 8 bit through bit replication, the 8-bit result is:
+
+ 0xc3 + ((255 - 0x0f) * 0x3c + 127) / 255 = 251
+
+ which corresponds to a real value of 0.984314. The difference from the
+ true value is 0.004482 which is bigger than the acceptable deviation
+ of 0.004. So, if we were to compute all the CONJOINT/DISJOINT
+ operators in floating point, or otherwise make them more accurate, the
+ acceptable deviation could be set at 0.0045.
+
+ If we were doing the 6-bit conversion with rounding:
+
+ (x / 63.0 * 255.0 + 0.5)
+
+ instead of bit replication, the deviation in this particular case
+ would be only 0.0005, so we may want to consider this at some
+ point.

+ test: Add new pixel-test regression test
+

+
+ test: Add new check-formats utility
+
+ Given an operator and two formats, this program will composite and
+ check all pixels where the red and blue channels are 0. That is, if
+ the two formats are a8r8g8b8 and a4r4g4b4, all source pixels matching
+ the mask
+
+ 0xff00ff00
+
+ are composited with the given operator against all destination pixels
+ matching the mask
+
+ 0xf0f0
+
+ and the result is then verified against the do_composite() function
+ that was moved to utils.c earlier.
+
+ This program reveals that a number of operators and format
+ combinations are not computed to within the precision currently
+ accepted by pixel_checker_t. For example:
+
+ check-formats over a8r8g8b8 r5g6b5 | grep failed | wc -l
+ 30
+
+ reveals that there are 30 pixel combinations where OVER produces
+ insufficiently precise results for the a8r8g8b8 and r5g6b5 formats.

+ stresstest: Ensure that the rasterizer is only given alpha formats
+
+ In c2cb303d33ec11390b93cabd90f0f9, return_if_fail()s were added to
+ prevent the trapezoid rasterizers from being called with non-alpha
+ formats. However, stress-test actually does call the rasterizers with
+ non-alpha formats, but because _pixman_log_error() is disabled in
+ versions with an odd minor number, the errors never materialized.
+
+ Fix this by changing the argument to random format to an enum of three
+ values DONT_CARE, PREFER_ALPHA, or REQUIRE_ALPHA, and then in the
+ switch that calls the trapezoid rasterizers, pass the appropriate
+ value for the function in question.

+
+ Improve L1 and L2 benchmark tests for caches that don't use allocate-on-write
+
+ In particular this affects single-core ARMs (e.g. ARM11, Cortex-A8), which
+ are usually configured this way. For other CPUs, this should only add a
+ constant time, which will be cancelled out by the EXCLUDE_OVERHEAD runs.
+
+ The problems were caused by cachelines becoming permanently evicted from
+ the cache, because the code that was intended to pull them back in again on
+ each iteration assumed too long a cache line (for the L1 test) or failed to
+ read memory beyond the first pixel row (for the L2 test). Also, the reloading
+ of the source buffer was unnecessary.
+
+ These issues were identified by Siarhei in this post:

+ pixman-combine-float.c: Use IS_ZERO() in clip_color() and set_sat()
+
+ The clip_color() function has some checks to avoid division by zero,
+ but they are done by comparing the value to 4 * FLT_EPSILON, where a
+ better choice is the IS_ZERO() macro that compares to +/- FLT_MIN.
+
+ In set_sat(), the check is that *max > *min before dividing by *max -
+ *min, but that has the potential problem that interactions between GCC
+ optimizions and 80 bit x87 registers could mean that (*max > *min) is
+ true in 80 bits, but (*max - *min) is 0 in 32 bits, so that the
+ division by zero is not prevented. Using IS_ZERO() here as well
+ prevents this.

+
+ Use pixman_transform_point_31_16() from pixman_transform_point()
+
+ Old functions pixman_transform_point() and pixman_transform_point_3d()
+ now become just wrappers for pixman_transform_point_31_16() and
+ pixman_transform_point_31_16_3d(). Eventually their uses should be
+ completely eliminated in the pixman code and replaced with their
+ extended range counterparts. This is needed in order to be able
+ to correctly handle any matrices and parameters that may come
+ to pixman from the code responsible for XRender implementation.

+ test: Added matrix-test for testing projective transform accuracy
+
+ This test uses __float128 data type when it is available
+ for implementing a "perfect" reference implementation. The
+ output from from pixman_transform_point_31_16() and
+ pixman_transform_point_31_16_affine() is compared with the
+ reference implementation to make sure that the rounding
+ errors may only show up in a single least significant bit.
+
+ The platforms and compilers, which do not support __float128
+ data type, can rely on crc32 checksum for the pseudorandom
+ transform results.

+
+ Add higher precision "pixman_transform_point_*" functions
+
+ The following new functions are added:
+
+ pixman_transform_point_31_16_3d() -
+ Calculates the product of a matrix and a vector multiplication.
+
+ pixman_transform_point_31_16() -
+ Calculates the product of a matrix and a vector multiplication.
+ Then converts the homogenous resulting vector [x, y, z] to
+ cartesian [x', y', 1] variant, where x' = x / z, and y' = y / z.
+
+ pixman_transform_point_31_16_affine() -
+ A faster sibling of the other two functions, which assumes affine
+ transformation, where the bottom row of the matrix is [0, 0, 1] and
+ the last element of the input vector is set to 1.
+
+ These functions transform a point with 31.16 fixed point coordinates from
+ the destination space to a point with 48.16 fixed point coordinates in
+ the source space.
+
+ The results are accurate and the rounding errors may only show up in
+ the least significant bit. No overflows are possible for the affine
+ transformations as long as the input data is provided in 31.16 format.
+ In the case of projective transformations, some output values may be not
+ representable using 48.16 fixed point format. In this case the results
+ are clamped to return maximum or minimum 48.16 values (so that the caller
+ can at least handle NONE and PAD repeats correctly).

+ Faster write-back for the C variant of r5g6b5 dest iterator
+
+ Unrolling loops improves performance, so just use it here.
+
+ Also GCC can't properly optimize this code for RISC processors and
+ allocate 0x1F001F constant in a register. Because this constant is
+ too large to be represented as an immediate operand in instructions,
+ GCC inserts some redundant arithmetics. This problem can be workarounded
+ by explicitly using a variable for 0x1F001F constant and also initializing
+ it by a read from another volatile variable. In this case GCC is forced
+ to allocate a register for it, because it is not seen as a constant anymore.

+
+ Handle solid images in the noop iterator
+
+ The noop src iterator already has code to handle solid images, but
+ that code never actually runs currently because it is not possible for
+ an image to have both a format code of PIXMAN_solid and a flag of
+ FAST_PATH_BITS_IMAGE.
+
+ If these two were to be set at the same time, the
+ fast_composite_tiled_repeat() fast path would trigger for solid images
+ (because it triggers for PIXMAN_any formats, which includes
+ PIXMAN_solid), but for solid images we can usually do better than that
+ fast path.
+
+ So this patch removes _pixman_solid_fill_iter_init() and instead
+ handles such images (along with repeating 1x1 bits images without an
+ alpha map) in pixman-noop.c.
+
+ When a 1x1R image is involved in the general composite path, before
+ this patch, it would hit this code in repeat() in pixman-inlines.h:
+
+ while (*c >= size)
+ *c -= size;
+ while (*c < 0)
+ *c += size;
+
+ and those loops could run for a huge number of iteratons (proportional
+ to the composite width). For such cases, the performance improvement
+ is really big:

+ float-combiner.c: Change tests for x == 0.0 tests to - FLT_MIN < x < FLT_MIN
+
+ pixman-float-combiner.c currently uses checks like these:
+
+ if (x == 0.0f)
+ ...
+ else
+ ... / x;
+
+ to prevent division by 0. In theory this is correct: a division-by-zero
+ exception is only supposed to happen when the floating point numerator is
+ exactly equal to a positive or negative zero.
+
+ However, in practice, the combination of x87 and gcc optimizations
+ causes issues. The x87 registers are 80 bits wide, which means the
+ initial test:
+
+ if (x == 0.0f)
+
+ may be false when x is an 80 bit floating point number, but when x is
+ rounded to a 32 bit single precision number, it becomes equal to
+ 0.0. In principle, gcc should compensate for this quirk of x87, and
+ there are some options such as -ffloat-store, -fexcess-precision=standard,
+ and -std=c99 that will make it do so, but these all have a performance
+ cost. It is also possible to set the FPU to a mode that makes it do
+ all computation with single or double precision, but that would
+ require pixman to save the existing mode before doing anything with
+ floating point and restore it afterwards.
+
+ Instead, this patch side-steps the issue by replacing exact checks for
+ equality with zero with a new macro that checkes whether the value is
+ between -FLT_MIN and FLT_MIN.
+
+ There is extensive reading material about this issue linked off the
+ infamous gcc bug 323:

+ ARM: make use of UQADD8 instruction even in generic C code paths
+
+ ARMv6 has UQADD8 instruction, which implements unsigned saturated
+ addition for 8-bit values packed in 32-bit registers. It is very useful
+ for UN8x4_ADD_UN8x4, UN8_rb_ADD_UN8_rb and ADD_UN8 macros (which would
+ otherwise need a lot of arithmetic operations to simulate this operation).
+ Since most of the major ARM linux distros are built for ARMv7, we are
+ much less dependent on runtime CPU detection and can get practical
+ benefits from conditional compilation here for a lot of users.

+ Faster conversion from a8r8g8b8 to r5g6b5 in C code
+
+ This change reduces 3 shifts, 3 ANDs and 2 ORs (total 8 arithmetic
+ operations) to 3 shifts, 2 ANDs and 2 ORs (total 7 arithmetic
+ operations).
+
+ We get garbage in the high 16 bits of the result, which might need
+ to be cleared when casting to uint16_t (it would bring us back to
+ total 8 arithmetic operations). However in the case if the result
+ of a8r8g8b8->r5g6b5 conversion is immediately stored to memory, no
+ extra instructions for clearing these garbage bits are needed.
+
+ This allows the a8r8g8b8->r5g6b5 conversion code to be compiled
+ into 4 instructions for ARM instead of 5 (assuming a good optimizing
+ compiler), which has no pipeline stalls on ARM11 as an additional
+ bonus.
+
+ The change in benchmark results for 'lowlevel-blt-bench src_8888_0565'
+ with PIXMAN_DISABLE="arm-simd arm-neon mips-dspr2 mmx sse2" and pixman
+ compiled by gcc-4.7.2:

+
+ pixman_composite_trapezoids: Return early if mask_format is not of TYPE_ALPHA
+
+ stress-test -s 0x17ee crashes because pixman_composite_trapezoids() is

+
+ The only mask_format that we actually support are those of TYPE_ALPHA,
+ so this patch add a return_if_fail() to ensure this.
+
+ Similarly, although currently it won't crash if given an invalid

+
+ radial: When comparing t to mindr, use >= rather than >
+
+ Radial gradients are conceptually rendered as a sequence of circles
+ generated by linearly extrapolating from the two circles given by the
+ gradient specification. Any circles in that sequence that would end up
+ with a negative radius are not drawn, a condition that is enforced by
+ checking that t * dr is bigger than mindr:
+
+ if (t * dr > mindr)
+
+ However, it is legitimate for a circle to have radius exactly 0, so
+ the test should use >= rather than >.
+
+ This gets rid of the dots in demos/radial-test except for when the c2
+ circle has radius 0 and a repeat mode of either NONE or NORMAL. Both
+ those dots correspond to a t value of 1.0, which is outside the
+ defined interval of [0.0, 1.0) and therefore subject to the repeat
+ algorithm. As a result, in the NONE case, a value of 1.0 turns into
+ transparent black. In the NORMAL case, 1.0 wraps around and becomes
+ 0.0 which is red, unlike 0.99 which is blue.

+
+ Add new pixman_filter_create_separable_convolution() API
+
+ This new API is a helper function to create filter parameters suitable
+ for use with PIXMAN_FILTER_SEPARABLE_CONVOLUTION.
+
+ For each dimension, given a scale factor, reconstruction and sample
+ filter kernels, and a subsampling resolution, this function will
+ compute a convolution of the two kernels scaled appropriately, then
+ sample that convolution and return the resulting vectors in a form
+ suitable for being used as parameters to
+ PIXMAN_FILTER_SEPARABLE_CONVOLUTION.
+
+ The filter kernels offered are the following:
+
+ - IMPULSE: Dirac delta function, ie., point sampling
+ - BOX: Box filter
+ - LINEAR: Linear filter, aka. "Tent" filter
+ - CUBIC: Cubic filter, currently Mitchell-Netravali
+ - GAUSSIAN: Gaussian function, sigma=1, support=3*sigma
+ - LANCZOS2: Two-lobed Lanczos filter
+ - LANCZOS3: Three-lobed Lanczos filter
+ - LANCZOS3_STRETCHED: Three-lobed Lanczos filter, stretched by 4/3.0.
+ This is the "Nice" filter from Dirty Pixels by
+ Jim Blinn.
+
+ The intended way to use this function is to extract scaling factors
+ from the transformation and then pass those to this function to get a
+ filter suitable for compositing with that transformation. The filter
+ kernels can be chosen according to quality and performance tradeoffs.
+
+ To get equivalent quality to GdkPixbuf for downscalings, use BOX for
+ both reconstruction and sampling. For upscalings, use LINEAR for
+ reconstruction and IMPULSE for sampling (though note that for
+ upscaling in both X and Y directions, simply using
+ PIXMAN_FILTER_BILINEAR will likely be a better choice).

+
+ Add new filter PIXMAN_FILTER_SEPARABLE_CONVOLUTION
+
+ This filter is a new way to use a convolution matrix for filtering. In
+ contrast to the existing CONVOLUTION filter, this new variant is
+ different in two respects:
+
+ - It is subsampled: Instead of just one convolution matrix, this
+ filter chooses between a number of matrices based on the subpixel
+ sample location, allowing the convolution kernel to be sampled at a
+ higher resolution.
+
+ - It is separable: Each matrix is specified as the tensor product of
+ two vectors. This has the advantages that many fewer values have to
+ be stored, and that the filtering can be done separately in the x
+ and y dimensions (although the initial implementation doesn't
+ actually do that).
+
+ The motivation for this new filter is to improve image downsampling
+ quality. Currently, the best pixman can do is the regular convolution
+ filter which is limited to coarsely sampled convolution kernels.
+
+ With this new feature, any separable filter can be used at any desired
+ resolution.

+ test: Added a better PRNG (pseudorandom number generator)
+
+ This adds a fast SIMD-optimized variant of a small noncryptographic
+ PRNG originally developed by Bob Jenkins:
+ http://www.burtleburtle.net/bob/rand/smallprng.html
+
+ The generated pseudorandom data is good enough to pass "Big Crush"
+ tests from TestU01 (http://en.wikipedia.org/wiki/TestU01).
+
+ SIMD code uses http://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html
+ which is a GCC specific extension. There is also a slower alternative
+ code path, which should work with any C compiler.
+
+ The performance of filling buffer with random data:
+ Intel Core i7 @2.8GHz (SSE2) : ~5.9 GB/s
+ ARM Cortex-A15 @1.7GHz (NEON) : ~2.2 GB/s
+ IBM Cell PPU @3.2GHz (Altivec) : ~1.7 GB/s

+ Add text file rounding.txt describing how rounding works
+
+ It is not entirely obvious how pixman gets from "location in the
+ source image" to "pixel value stored in the destination". This file
+ describes how the filters work, and in particular how positions are
+ rounded to samples.

+
+ Convolution filter: round color values instead of truncating
+
+ The pixel computed by the convolution filter should be rounded off,
+ not truncated. As a simple example consider a convolution matrix
+ consisting of five times 0x3333. If all five all five input pixels are
+ 0xff, then the result of truncating will be
+
+ (5 * 0x3333 * 255) >> 16 = 254
+
+ But the real value of the computation is (5 * 0x3333 / 65536.0) * 254
+ = 254.9961, so the error is almost 1. If the user isn't very careful
+ about normalizing the convolution kernel so that it sums to one in
+ fixed point, such error might cause solid images to change color, or
+ opaque images to become translucent.
+
+ The fix is simply to round instead of truncate.

+
+ Round fixed-point multiplication
+
+ After two fixed-point numbers are multiplied, the result is shifted
+ into place, but up until now pixman has simply discarded the low-order
+ bits instead of rounding to the closest number.
+
+ Fix that by adding 0x8000 (or 0x2 in one place) before shifting and
+ update the test checksums to match.

+ pixman_composite_trapezoids(): don't clip to extents for some operators
+
+ pixman_composite_trapezoids() is supposed to composite across the

+ matter since a zero source has no effect on the destination. But for

+
+ So for such operators where a zero source has an effect, don't clip to

+
+ configure.ac: PIXMAN_LINK_WITH_ENV fix
+
+ (fixes bug #52101)
+
+ On MirBSD, the compiler produces a (harmless) warning when the compiler
+ is called without the standard CFLAGS:
+
+ foo.c:0: note: someone does not honour COPTS correctly, passed 0 times
+
+ However, PIXMAN_LINK_WITH_ENV considers _any_ output on stderr as an
+ error, even if the exit status of the compiler is 0. Furthermore, it
+ resets CFLAGS and LDFLAGS at the start. On MirBSD, this will lead to a
+ warning in each test, making all such tests fail. In particular, the
+ pthread_setspecific test fails, thus pixman is compiled without thread
+ support. This leads to compile errors later on, or at least it did when
+ I tried this on pkgsrc. Re-adding the saved CFLAGS, LDFLAGS and LIBS
+ before the test makes it work.
+
+ The second hunk inverts the order of the pthread flag checks. On BSD
+ systems (this is true at least on OpenBSD and MirBSD), both -lpthread
+ and -pthread work but the latter is "preferred", whatever this means.

+
+ This provides a way to enable MIPS DSP ASE optimizations if running

+
+ Only regard images as pixbufs if they have identity transformations
+
+ In order for a src/mask pair to be considered a pixbuf, they have to
+ have identical transformations, but we don't check for that. Since the
+ only fast paths we have for pixbufs require identity transformations,
+ it sufficies to check that both source and mask are
+ untransformed.
+
+ This is also the reason that this bug can't be triggered by any test
+ code - if the source and mask had different transformations, we would
+ consider them a pixbuf, but then wouldn't take the fast path because
+ at least one of the transformations would be different from the
+ identity.

+
+ pixman-access.c: Add floating point accessor functions
+
+ Three new function pointer fields are added to bits_image_t:
+
+ fetch_scanline_float
+ fetch_pixel_float
+ store_scanline_float
+
+ similar to the existing 32 and 64 bit accessors. The fetcher_info_t
+ struct in pixman_access similarly gets a new get_scanline_float field.
+
+ For most formats, the new get_scanline_float field is set to a new
+ function fetch_scanline_generic_float() that first calls the 32 bit
+ fetcher uses the 32 bit scanline fetcher and then expands these pixels
+ to floating point.
+
+ For the 10 bpc formats, new floating point accessors are added that
+ use pixman_unorm_to_float() and pixman_float_to_unorm() to convert
+ back and forth.
+
+ The PIXMAN_a8r8g8b8_sRGB format is handled with a 256-entry table that
+ maps 8 bit sRGB channels to linear single precision floating point
+ numbers. The sRGB->linear direction can then be done with a simple
+ table lookup.
+
+ The other direction is currently done with 4096-entry table which
+ works fine for 16 bit integers, but not so great for floating
+ point. So instead this patch uses a binary search in the sRGB->linear
+ table. The existing 32 bit accessors for the sRGB format are also
+ converted to use this method.

+
+ Add pixman-combine-float.c
+
+ This file contains floating point implementations of combiners for all
+ pixman operators. These combiners operate on buffers containing single
+ precision floating point pixels stored in (a, r, g, b) order.
+
+ The combiners are added to the pixman_implementation_t struct, but
+ nothing uses them yet.
+
+ This commit incorporates a number of bug fixes contributed by Andrea
+ Canciani.
+
+ Some notes:
+
+ - The combiners are making sure to never divide by zero regardless of
+ input, so an application could enable divide-by-zero exceptions and
+ pixman wouldn't generate any.
+
+ - The operators are implemented according to the Render spec. Ie.,
+
+ - If the input pixels are between 0 and 1, then so is the output.
+
+ - The source and destination coefficients for the conjoint and
+ disjoint operators are clamped to [0, 1].
+
+ - The PDF operators are not described in the render spec, and the
+ implementation here doesn't do any clamping except in the final
+ conversion from floating point to destination format.
+
+ All of the above will need to be rethought if we add support for pixel
+ formats that can support negative and greater-than-one pixels. It is
+ in fact already the case in principle that convolution filters can
+ produce pixels with negative values, but since these go through the
+ broken "wide" path that narrows everything to 32 bits, these negative
+ values don't currently survive to the combiners.

+
+ Fix for infinite-loop test
+
+ The infinite loop detected by "affine-test 212944861" is caused by an
+ overflow in this expression:
+
+ max_x = pixman_fixed_to_int (vx + (width - 1) * unit_x) + 1;
+
+ where (width - 1) * unit_x doesn't fit in a signed int. This causes
+ max_x to be too small so that this:
+
+ src_width = 0
+
+ while (src_width < REPEAT_NORMAL_MIN_WIDTH && src_width <= max_x)
+ src_width += src_image->bits.width;
+
+ results in src_width being 0. Later on when src_width is used for
+ repeat calculations, we get the infinite loop.
+
+ By casting unit_x to int64_t, the expression no longer overflows and
+ affine-test 212944861 and infinite-loop no longer loop forever.

+
+ Fix bugs in component alpha combiners for separable PDF operators
+
+ In general, the component alpha version of an operator is supposed to
+ do this:
+
+ - multiply source with mask in all channels
+ - multiply mask with source alpha in all channels
+ - compute the regular operator in all channels using the
+ mask value whenever source alpha is called for
+
+ The first two steps are usually accomplished with the function
+ combine_mask_ca(), but for operators where source alpha is not used,
+ such as SRC, ADD and OUT, the simpler function
+ combine_mask_value_ca(), which doesn't compute the new mask values,
+ can be used.
+
+ However, the PDF blend modes generally *do* make use of source alpha,
+ so they can't use combine_mask_value_ca() as they do now. They have to
+ use combine_mask_ca().
+
+ This patch fixes this in combine_multiply_ca() and the CA combiners
+ generated by PDF_SEPARABLE_BLEND_MODE.

+
+ Add support for sRGB surfaces
+
+ sRGB format is defined as a new format type, PIXMAN_TYPE_ARGB_SRGB. One form of
+ this type is provided, PIXMAN_a8r8g8b8_sRGB. Use of an sRGB format triggers
+ wide processing, and the pixel fetch/store functions handle the relevant
+ conversion between color spaces. Pixman itself is thought to compose in the
+ linearized sRGB color space.
+
+ sRGB conversion is tabularized. For sRGB to linear, we are using only 256
+ values because the current source format uses 8 bits per component precision.
+ For linear to sRGB, it turns out that only 4096 brightness levels are required
+ to generate all of the 256 sRGB color values, and therefore only 12 bits per
+ component are considered during store. As a special case, a no-op
+ sRGB->linear->sRGB conversion is constructed to be lossless by adjusting the
+ sRGB->linear conversion table where necessary.

+
+ Cleanups and simplifications in x86 CPU feature detection
+
+ A new function pixman_cpuid() is added that runs the cpuid instruction
+ and returns the results. On GCC this function uses inline assembly; on
+ MSVC, the function calls the __cpuid intrinsic.
+
+ There is also a new function called have_cpuid() which detects whether
+ cpuid is available. On x86-64 and MSVC, it simply returns TRUE; on
+ x86-32 bit, it checks whether the 22nd bit of eflags can be
+ modified. On MSVC this does have the consequence that pixman will no
+ longer work CPUS without cpuid (ie., older than 486 and some 486
+ models).
+
+ These two functions together makes it possible to write a generic
+ detect_cpu_features() in plain C. This function is then used in a new
+ have_feature() function that checks whether a specific set of feature
+ bits is available.
+
+ Aside from the cleanups and simplifications, the main benefit from
+ this patch is that pixman now can do feature detection on x86-64, so
+ that newer instruction sets such as SSSE3 and SSE4.1 can be used. (And
+ apparently the assumption that x86-64 CPUs always have MMX and SSE2 is
+ no longer correct: Knight's Corner is x86-64, but doesn't have them).
+
+ V2: Rename the constants in the getisax() code, as pointed out by Alan
+ Coopersmith. Also reinstate the result variable and initialize
+ features to 0.
+
+ V3: Fixes for the fact that the upper 32 bits of a 64 bit register are
+ zeroed whenever the corresponding 32 bit register is written to.
+
+ V4: Fixes for the fact that in 32 bit mode, when gcc is not optimizing
+ there were not enough registers available. The new code uses the "a",
+ "b", "c", and "d" constraints instead, and has two separate versions
+ for 32 and 64 bit modes.

+
+ Simplify CPU detection on PPC.
+
+ Get rid of the initialized and have_vmx static variables in
+ pixman-ppc.c There is no point to them since CPU detection only
+ happens once per process.
+
+ On Linux, just read /proc/self/auxv instead of generating the filename
+ with getpid() and don't bother with the stack buffer. Instead just
+ read the aux entries one by one.

+
+ Simplifications to ARM CPU detection
+
+ Organize pixman-arm.c such that each operating system/compiler exports
+ a detect_cpu_features() function that returns a bitmask with the
+ various features that we are interested in. A new function
+ have_feature() then calls this function, caches the result, and return
+ whether the given feature is available.
+
+ The result is that all the pixman_have_arm_<feature> functions become
+ redundant and can be deleted.

+ test: Make stress-test more likely to actually composite something
+
+ stress-test current almost never composites anything because the clip
+ rectangles and transformations are such that either
+ _pixman_compute_composite_region32() or analyze_extent() will return
+ FALSE.
+
+ Fix this by:
+
+ - making log_rand() return smaller numbers so that the clip rectangles
+ are more likely to be within the destination image
+
+ - adding rand_x() and rand_y() functions that pick positions within an
+ image and using them for positioning alpha maps and source/mask
+ positions.
+
+ - making it less likely that clip regions are used in general
+
+ These changes make the test take longer, so speed it up a little by
+ making most images smaller and by reducing the maximum convolution
+ filter from 17x19 to 3x4.
+
+ With these changes, stress-test reveals a crash in iteration 0xd39
+ where fast_composite_tiled_repeat() creates an indexed image without a
+ palette.

+ bits-image: Turn all the fetchers into iterator getters
+
+ Instead of caching these fetchers in the image structure, and then
+ have the iterator getter call them from there, simply change them to
+ be iterator getters themselves.
+
+ This avoids an extra indirect function call and lets us get rid of the
+ get_scanline_32/64 fields in pixman_image_t.

+
+ Faster unorm_to_unorm for wide processing.
+
+ Optimizing the unorm_to_unorm functions allows a speedup from:
+
+ src_8888_2x10 = L1: 62.08 L2: 60.73 M: 59.61 ( 4.30%) HT: 46.81
+ VT: 42.17 R: 43.18 RT: 26.01 (325Kops/s)
+
+ to:
+
+ src_8888_2x10 = L1: 76.94 L2: 78.43 M: 75.87 ( 5.59%) HT: 56.73
+ VT: 52.39 R: 53.00 RT: 29.29 (363Kops/s)
+
+ on a i7 Q720 -based laptop.
+
+ The key of the patch is the observation that unorm_to_unorm's work can
+ more easily be done with a simple multiplication and shift, when the
+ function is applied repeatedly and the parameters are not compile-time
+ constants. For instance, converting from 0xfe to 0xfefe (expanding
+ from 8 bits to 16 bits) can be done by calculating
+
+ c = c * 0x101
+
+ However, sometimes the result is not a neat replication of all the
+ bits. For instance, going from 10 bits to 16 bits can be done by
+ calculating
+
+ c = c * 0x401UL >> 4
+
+ where the intermediate result is 20 bit wide repetition of the 10-bit
+ pattern followed by shifting off the unnecessary lowest bits.
+
+ The patch has the algorithm to calculate the factor and the shift, and
+ converts the code to use it.

+ autotools: use custom build rule to build iwMMXt code
+

+ -march=iwmmxt and override the march value, so we have to use a custom

+
+ Speed up _pixman_composite_glyphs_no_mask()
+
+ Bypass much of the overhead of pixman_image_composite32() by only
+ computing the composite region once instead of once per glyph, and by
+ only looking up the composite function whenever the glyph format or
+ flags change.
+
+ As part of this, the pixman_compute_composite_region32() was renamed
+ to _pixman_compute_composite_region32() and exported in
+ pixman-private.h.
+
+ I couldn't find a trace that would reliably demonstrate that this is
+ actually an improvement by itself (since _pixman_composite_glyphs_no_mask()
+ is called so rarely), but together with the following optimization for
+ solid sources, there is a small but reliable improvement to the
+ xfce4-a1-terminal cairo trace.

+ Speed up pixman_composite_glyphs()

+
+ - Only using a white source when the glyph format is different from

+
+ Add support for alpha maps to compute_crc32_for_image().
+
+ When a destination image I has an alpha map A, the following rules apply:
+
+ - If I has an alpha channel itself, the content of that channel is
+ undefined
+
+ - If A has RGB channels, the content of those channels is
+ undefined.
+
+ Hence in order to compute the CRC32 for such an image, we have to mask
+ off the alpha channel of the image, and the RGB channels of the alpha
+ map.
+
+ V2: Shifting by 32 is undefined in C

+
+ Add pixman_glyph_cache_t API
+
+ This new API allows entire glyph strings to be composited in one go
+ which reduces overhead compared to multiple calls to
+ pixman_image_composite32().
+
+ The pixman_glyph_cache_t is a hash table that maps two keys (a "font"
+ and a "glyph" key, but they are just keys; there is no distinction
+ between them as far as pixman is concerned) to a glyph. Glyphs in the
+ cache can be composited through two new entry points
+ pixman_glyph_cache_composite_glyphs() and
+ pixman_glyph_cache_composite_glyphs_no_mask().
+
+ A glyph cache may only be inserted into when it is "frozen", which is
+ achieved by calling pixman_glyph_cache_freeze(). When
+ pixman_glyph_cache_thaw() is later called, if the cache has become too
+ crowded, some glyphs (currently the least-recently-used) will
+ automatically be evicted. This means that a user must ensure that all
+ the required glyphs are present in the cache before compositing a
+ string. The intended way to use the cache is like this:
+
+ pixman_glyph_t glyphs[MAX_GLYPHS];
+
+ pixman_glyph_cache_freeze (cache);
+
+ for (i = 0; i < n_glyphs; ++i)
+ {
+ const void *g;
+
+ if (!(g = pixman_glyph_cache_lookup (cache, font_key, glyph_key)))
+ {
+ img = <rasterize glyph as a pixman_image_t>;
+
+ g = pixman_glyph_cache_insert (cache, font_key, glyph_key,
+ glyph_origin_x, glyph_origin_y,
+ img);
+
+ if (!g)
+ {
+ /* Clean up out-of-memory condition */
+ goto oom;
+ }
+
+ glyphs[i].pos_x = glyph_x_pos;
+ glyphs[i].pos_y = glyph_y_pos;
+ glyphs[i].glyph = g;
+ }
+ }
+
+ pixman_composite_glyphs (op, src, dest, ..., cache, n_glyphs, glyphs);
+
+ pixman_glyph_cache_thaw (cache);
+
+ V2:
+ - Move glyphs to front of the MRU list when they are used. Pointed
+ out by Behdad Esfahbod.
+ - Composite glyphs with (white IN glyph) ADD mask in order to support
+ mixed a8 and a8r8g8b8 glyphs. Also pointed out by Behdad.
+ - Add pixman_glyph_get_mask_format

+ Add doubly linked lists
+
+ This commit adds some new inline functions to maintain a doubly linked
+ list.
+
+ The way to use them is to embed a pixman_link_t into the structures
+ that should be linked, and use a pixman_list_t as the head of the
+ list.
+
+ The new functions are
+
+ pixman_list_init (pixman_list_t *list);
+ pixman_list_prepend (pixman_list_t *list, pixman_link_t *link);
+ pixman_list_move_to_front (pixman_list_t *list, pixman_link_t *link);
+
+ There are also a new macro:
+
+ CONTAINER_OF(type, member, data);
+
+ that can be used to get from a pointer to a member to the containing
+ structure.
+
+ V2: Use the C89 macro offsetof() instead of rolling our own -
+ suggested by Alan Coopersmith.

+ Pass the full image flags to iterators
+
+ When pixman_image_composite32() is called some flags are computed that

+
+ Fix that by passing the info->{src, mask, dest}_flags on to the
+ iterator initialization and store the flags in the iter struct as
+ "image_flags". At the same time rename the *iterator* flags variable
+ to "iter_flags" to avoid confusion.

+
+ test: Composite with solid images instead of using pixman_image_fill_*
+
+ There is a couple of places where the test suite uses the
+ pixman_image_fill_* functions to initialize images. These functions
+ can fail, and will do so if the "fast" implementation is disabled.
+
+ So to make sure the test suite passes even using
+ PIXMAN_DISABLE="fast", use pixman_image_composite32() with a solid
+ image instead of pixman_image_fill_*.

+
+ MIPS: DSPr2: Fix bug in over_n_8888_8888_ca/over_n_8888_0565_ca routines
+
+ In main loop (unrolled by factor 2), instead of negating multiplied
+ mask values by srca, values of srca was negated, and passed as alpha
+ argument for
+
+ UN8x4_MUL_UN8x4_ADD_UN8x4 macro.
+
+ Instead of:
+
+ ma = ~ma;
+ UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s);
+
+ Code was doing this:
+
+ ma = ~srca;
+ UN8x4_MUL_UN8x4_ADD_UN8x4 (d, ma, s);
+
+ Key is in substituting registers s0/s1 (containing srca value), with
+ t0/t1 containing mask values multiplied by srca. Register usage is
+ also improved (less registers are saved on stack, for
+ over_n_8888_8888_ca routine).
+
+ The bug was introduced in commit d2ee5631 and revealed by composite test.

+ configure.ac: Fail the ARM/iwMMXt test if not compiling with -march=iwmmxt
+
+ If not compiling with -march=iwmmxt, the configure test will still pass,
+ thinking that the __builtin_arm_* intrinsic is a function instead of
+ generating a single instruction. Since no linking is done, the configure
+ test doesn't catch this, and we get linking errors in the build.

+
+ Uses the pmadd technique described in

+
+ The technique uses the packssdw instruction which uses signed
+ saturatation. This works in their example because they pack 888 to 555
+ leaving the high bit as zero. For packing to 565, it is unsuitable, so
+ we replace it with an or+shuffle.

+ mmx: Use Loongson pinsrh instruction in pack_565
+
+ The pinsrh instruction is analogous to MMX EXT's pinsrw, except like
+ other Loongson vector instructions it cannot access the general purpose
+ registers. In the cases of other Loongson vector instructions, this is a
+ headache, but it is actually a good thing here. Since the instruction is
+ different from MMX, I've named the intrinsic loongson_insert_pi16.

+ mmx: don't pack and unpack src unnecessarily
+
+ The combine function was store8888'ing the result, and all consumers
+ were immediately load8888'ing it, causing lots of unnecessary pack and
+ unpack instructions.
+
+ It's a very straight forward conversion, except for mmx_combine_over_u
+ and mmx_combine_saturate_u. mmx_combine_over_u was testing the integer
+ result to skip pixels, so we use the is_* functions to test the __m64
+ data directly without loading it into an integer register.
+
+ For mmx_combine_saturate_u there's not a lot we can do, since it uses
+ DIV_UN8.

+ mmx: make ldq_u take __m64* directly
+
+ Before, if __m64 is allocated in vector or floating-point registers,
+
+ __m64 vs = ldq_u((uint64_t *)src);
+
+ would cause src to be loaded into an integer register and then
+ transferred to an __m64 register. By switching ldq_u's argument type to
+ __m64 we give the compile enough information to recognize that it can
+ load to the vector register directly.
+
+ This patch is necessary for the Loongson optimizations when __m64 is
+ typedef'd as double.

+ bits_image_fetch_pixel_convolution(): Make sure channels are signed
+
+ In the computation:
+
+ srtot += RED_8 (pixel) * f
+
+ RED_8 (pixel) is an unsigned quantity, which means the signed filter
+ coefficient f gets converted to an unsigned integer before the
+ multiplication. We get away with this because when the 32 bit unsigned
+ result is converted to int32_t, the correct sign is produced. But if
+ srtot had been an int64_t, the result would have been a very large
+ positive number.
+
+ Fix this by explicitly casting the channels to int.

+ Just use xmmintrin.h when building with Solaris Studio compilers
+
+ Since the Solaris Studio compilers don't have a mode where MMX
+ instructions are available and SSE instructions are not, we can
+ just use the <xmmintrin.h> header directly.
+
+ Fixes build failure due to Studio not supporting the __gnu_inline__
+ or __artificial__ attributes.

+ Disable implementations mentioned in the PIXMAN_DISABLE environment variable.
+
+ With this, it becomes possible to do
+
+ PIXMAN_DISABLE="sse2 mmx" some_app
+
+ which will run some_app without SSE2 and MMX enabled. This is useful
+ for benchmarking, testing and narrowing down bugs.
+
+ The current list of implementations that can be disabled:
+
+ fast
+ mmx
+ sse2
+ arm-simd
+ arm-iwmmxt
+ arm-neon
+ mips-dspr2
+ vmx
+
+ The general and noop implementations can't be disabled because pixman
+ depends on those being available for correct operation.

+
+ Disable MMX when Clang is being used.
+
+ There are several issues with the Clang compiler and pixman-mmx.c:
+
+ - When not optimizing, it doesn't seem to recognize that an argument
+ to an __always_inline__ function is compile-time constant. This
+ results in this error being produced:
+
+ fatal error: error in backend: Invalid operand for inline asm
+ constraint 'K'!
+
+ - This inline assembly:
+
+ asm ("pmulhuw %1, %0\n\t"
+ : "+y" (__A)
+ : "y" (__B)
+ );
+
+ results in
+
+ fatal error: error in backend: Unsupported asm: input constraint
+ with a matching output constraint of incompatible type!
+
+ So disable MMX when the compiler is Clang.

+
+ test: Add a new "pixel_checker_t" object.
+
+ Add a new pixel_checker_t object to test/utils.[ch]. This object
+ should be initialized with a format and can then be used to check
+ whether a given "real" pixel in that format is close enough to a
+ "perfect" pixel given as a double precision ARGB struct.
+
+ The acceptable deviation is calcuated as follows. Each channel of the
+ perfect pixel has 0.004 subtracted from it and is then converted to
+ the format. The resulting value is the minimum value that will be
+ accepted. Similarly, to compute the maximum value, the channel has
+ 0.004 added to it and is then converted to the given format. Checking
+ a pixel is then a matter of splitting it into channels and checking
+ that each is within the computed bounds.
+
+ The value of 0.004 was chosen because it is the minimum one that will
+ make the existing composite test pass (see next commit). A problem
+ with this value is that it causes 0xFE to be acceptable when the
+ correct value is 1.0, and 0x01 to be acceptable when the correct value
+ is 0. It would be better if, when the result is exactly 0 or exactly
+ 1, an a8r8g8b8 pixel were required to produce exactly 0x00 or 0xff to
+ preserve full black and full white. A deviation value of 0.003 would
+ produce this, but currently this would cause tests with operators that
+ involve divisions to fail.

+ Reject trapezoids where top (botttom) is above (below) the edges
+
+ When a trapezoid has a top/bottom that is above/below the left/right
+ edges, degenerate trapezoids become possible. For example the edge
+ could be very short and close to horizontal. If the bottom edge is far
+ below the bottom point of such a short edge, the result is that the
+ lower right corner of the trapezoid will be extremely far to the left.
+
+ This kind of trapezoid causes overflows in the rasterization code, so
+ change pixman_trapezoid_valid() to reject them.

+
+ Fix a bunch of signed overflow issues
+
+ In pixman-fast-path.c: (1 << 31) - 1 causes a signed overflow, so
+ change to (1U << n) - 1.
+
+ In pixman-image.c: The check for whether m10 == -m01 will overflow
+ when -m01 == INT_MIN. Instead just check whether the variables are 1
+ and -1.
+
+ In pixman-utils.c: When the depth of the topmost channel is 0, we can
+ end up shifting by 32.
+
+ In blitters-test.c: Replicating the mask would end up shifting more
+ than 32.
+
+ In region-contains-test.c: Computing the average of two large integers
+ could overflow. Instead add half the difference between them to the
+ first integer.
+
+ In stress-test.c: Masking the value in fake_reader() would sometimes
+ shift by 32. Instead just use the most significant bits instead of
+ the least significant.
+
+ All these issues were found by the IOC tool:

+ gradient-walker: For NONE repeats, when x < 0 or x > 1, set both colors to 0
+
+ ec7c9c2b6865b48b8bd14e4 introduced a bug where NONE gradients would be
+ misrendered, causing the area outside the gradient to be treated as a
+ (very) long fade to transparent.The problem was that a check for
+ positions outside the gradients were dropped in favor of relying on
+ the sentinels.
+
+ Aside from misrendering, this also caused a signed integer overflow
+ when the code would compute a stepper size based on MIN_INT32.
+
+ This patches fixes the issue by reinstating a check for these cases
+ and setting both the right and left colors to transparent black.

+
+ ARM: NEON: Bilinear macro template for instruction scheduling
+
+ This macro template takes 6 code blocks.
+
+ 1. process_last_pixel
+ 2. process_two_pixels
+ 3. process_four_pixels
+ 4. process_pixblock_head
+ 5. process_pixblock_tail
+ 6. process_pixblock_tail_head
+
+ process_last_pixel does not need to update horizontal weight. This
+ is done by the template. two and four code block should update
+ horizontal weight inside of them. head/tail/tail_head blocks
+ consist unrolled core loop. You can apply instruction scheduling
+ to the tail_head blocks.
+
+ You can also specify size of the pixel block. Supported size is 4
+ and 8. If you want to use mask, give BILINEAR_FLAG_USE_MASK flags
+ to the template, then you can use register MASK. When using d8~d15
+ registers, give BILINEAR_FLAG_USE_ALL_NEON_REGS to make sure
+ registers are properly saved on the stack and later restored.

+
+ Strength-reduce BILINEAR filter to NEAREST filter for identity transforms
+
+ An image with a bilinear filter and an identity transform is
+ equivalent to one with a nearest filter, so there is no reason the
+ standard fast paths shouldn't be usable.
+
+ But because a BILINEAR filter samples a 2x2 pixel block in the source
+ image, FAST_PATH_SAMPLES_COVER_CLIP can't be set in the case where the
+ source area is the entire image, because some compositing operations
+ might then read pixels outside the image.
+
+ This patch fixes the problem by splitting the
+ FAST_PATH_SAMPLES_COVER_CLIP flag into two separate flags
+ FAST_PATH_SAMPLES_COVER_CLIP_NEAREST and
+ FAST_PATH_SAMPLES_COVER_CLIP_BILINEAR that indicate that the clip
+ covers the samples taking into account NEAREST/BILINEAR filters
+ respectively.
+
+ All the existing compositing operations that require
+ FAST_PATH_SAMPLES_COVER_CLIP then have their flags modified to pick
+ either COVER_CLIP_NEAREST or COVER_CLIP_BILINEAR depending on which
+ filter they depend on.
+
+ In compute_image_info() both COVER_CILP_NEAREST and
+ COVER_CLIP_BILINEAR can be set depending on how much room there is
+ around the clip rectangle.
+
+ Finally, images with an identity transform and a bilinear filter get
+ FAST_PATH_NEAREST_FILTER set as well as FAST_PATH_BILINEAR_FILTER.

+
+ test: better coverage for BILINEAR->NEAREST filter optimization
+
+ The upcoming optimization which is going to be able to replace BILINEAR filter
+ with NEAREST where appropriate needs to analyze the transformation matrix
+ and not to make any mistakes.
+
+ The changes to affine-test include:
+ 1. Higher chance of using the same scale factor for x and y axes. This can help
+ to stress some special cases (for example the case when both x and y scale
+ factors are integer). The same applies to x/y translation.
+ 2. Introduced a small chance for "corrupting" transformation matrix by flipping
+ random bits. This supposedly can help to identify the cases when some of the
+ fast paths or other code logic is wrongly activated due to insufficient checks.

+ single operation:
+
+ << /content //COLOR_ALPHA /width 480 /height 800 >> surface context
+ << /width 1 /height 677 /format //ARGB32 /source <|!!!@jGb!m5gD']#$jFHGWtZcK&2i)Up=!TuR9`G<8;ZQp[FQk;emL9ibhbEL&NTh-j63LhHo$E=mSG,0p71`cRJHcget4%<S\X+~> >> image pattern
+ //EXTEND_REPEAT set-extend
+ set-source
+ n 0 0 480 677 rectangle

+ pop
+
+ which is a simple composition of a single pixel wide image. Sadly this
+ is a workaround for lack of independent repeat-x/y handling in cairo and
+ pixman. Worse still is that the worst-case behaviour of the general repeat
+ path is for width 1 images...

+
+ In pixman_image_create_bits() allow images larger than 2GB
+
+ There is no reason for pixman_image_create_bits() to check that the
+ image size fits in int32_t. The correct check is against size_t since
+ that is what the argument to calloc() is.
+
+ This patch fixes this by adding a new _pixman_multiply_overflows_size()
+ and using it in create_bits(). Also prepend an underscore to the names
+ of other similar functions since they are internal to pixman.
+
+ V2: Use int, not ssize_t for the arguments in create_bits() since
+ width/height are still limited to 32 bits, as pointed out by Chris
+ Wilson.

+
+ Speed up pixman_region{,32}_contains_rectangle()
+
+ When someone selects some text in Firefox under a non-composited X
+ server and initiates a drag, a shaped window is created with a complex
+ shape corresponding to the outline of the text. Then, on every mouse
+ movement pixman_region_contains_rectangle() is called many times on
+ that complicated region. And pixman_region_contains_rectangle() is
+ doing a linear scan through the rectangles in the region, although the
+ scan does exit when it finds the first box that can't possibly
+ intersect the passed-in rectangle.
+
+ This patch changes the loop so that it uses a binary search to skip
+ boxes that don't overlap the current y position. The performance
+ improvement for the text dragging case is easily noticable.
+
+ V2: Use the binary search for the "getting up to speed or skippping
+ remainder of band" as well.

+
+ C fast path for scaled src_x888_8888 with nearest filter
+
+ The necessity is justified by a message in the pixman mailing list:
+ http://lists.freedesktop.org/archives/pixman/2011-July/001330.html
+
+ NONE repeat is not supported, but could be added by tweaking
+ the interpretation and making use of 'fully_transparent_src'
+ scanline function argument.

+ Bilinear REPEAT_NORMAL source line extension for too short src_width
+
+ To avoid function call and other calculation overhead, extend source
+ scanline into temporary buffer when source width is too small.
+ Temporary buffer will be repeatedly accessed, so extension cost is
+ very small due to cache effect.

+
+ REPEAT_NORMAL support for bilinear fast path template
+
+ The basic idea is to break down normal repeat into a set of
+ non-repeat scanline compositions and stitching them together.
+
+ Bilinear may interpolate last and first pixels of source scanline.
+ In this case, we can use temporary wrap around buffer.

+
+ Replace boolean arguments with flags for bilinear fast path template
+
+ By replacing boolean arguments with flags, the code can be more
+ readable and flags can be extended to do some more things later.
+
+ Currently following flags are defined.
+
+ FLAG_NONE
+ - No flags are turned on.
+
+ FLAG_HAVE_SOLID_MASK
+ - Template will generate solid mask composite functions.
+
+ FLAG_HAVE_NON_SOLID_MASK
+ - Template will generate bits mask composite functions.
+
+ FLAG_HAVE_SOLID_MASK and FLAG_NON_SOLID_MASK should be mutually
+ exclusive.

+ ARM: Fix two bugs in neon_composite_over_n_8888_0565_ca().
+
+ The first bug is that a vmull.u8 instruction would store its result in
+ the q1 register, clobbering the d2 register used later on. The second
+ is that a vraddhn instruction would overwrite d25, corrupting the q12

+
+ Fixing the second bug caused a pipeline bubble where the d18 register
+ would be unavailable for a clock cycle. This is fixed by swapping the

+ Offset rendering in pixman_composite_trapezoids() by (x_dst, y_dst)
+
+ Previously, this function would do coordinate calculations in such a
+ way that (x_dst, y_dst) would only affect the alignment of the source

+ absolute destination coordinates. This is unlike the
+ pixman_image_composite() function which also registers the mask to the
+ destination.
+
+ This patch makes it so that traps are also offset by (x_dst, y_dst).
+
+ Also add a comment explaining how this function is supposed to
+ operate, and update tri-test.c and composite-trap-test.c to deal with
+ the new semantics.

+
+ Add simple support for the r8g8b8a8 and r8g8b8x8 formats.
+
+ This format is particularly useful on big-endian architectures, where RGBA in
+ memory/file order corresponds to r8g8b8a8 as an uint32_t. This is important
+ because RGBA is in some cases the only available choice (for example as a pixel
+ format in OpenGL ES 2.0).

+
+ test: Randomize some tests if PIXMAN_RANDOMIZE_TESTS is set
+
+ This patch makes so that composite and stress-test will start from a
+ random seed if the PIXMAN_RANDOMIZE_TESTS environment variable is
+ set. Running the test suite in this mode is useful to get more test
+ coverage.
+
+ Also, in stress-test.c make it so that setting the initial seed causes
+ threads to be turned off. This makes it much easier to see when
+ something fails.

+ Main loop template for fast single pass bilinear scaling
+
+ Can be used for implementing SIMD optimized fast path
+ functions which work with bilinear scaled source images.
+
+ Similar to the template for nearest scaling main loop, the
+ following types of mask are supported:
+ 1. no mask
+ 2. non-scaled a8 mask with SAMPLES_COVER_CLIP flag
+ 3. solid mask
+
+ PAD repeat is fully supported. NONE repeat is partially
+ supported (right now only works if source image has alpha
+ channel or when alpha channel of the source image does not
+ have any effect on the compositing operation).

+ Add direct-write optimization back
+
+ Introduce a new ITER_LOCALIZED_ALPHA flag that indicates that the
+ alpha value computed is used only for the alpha channel of the output;
+ it doesn't affect the RGB channels.
+
+ Then in pixman-bits-image.c, if a destination is either a8r8g8b8 or

+ directly into the image.

+Date: Fri Dec 10 11:30:27 2010 -0500
+
+ Add iterators in the general implementation
+
+ We add a new structure called a pixman_iter_t that encapsulates the
+ information required to read scanlines from an image. It contains two
+ functions, get_scanline() and write_back(). The get_scanline()
+ function will generate pixels for the current scanline. For iterators
+ for source images, it will also advance to the next scanline. The
+ write_back() function is only called for destination images. Its
+ function is to write back the modified pixels to the image and then
+ advance to the next scanline.
+
+ When an iterator is initialized, it is passed this information:
+
+ - The image to iterate
+
+ - The rectangle to be iterated
+
+ - A buffer that the iterator may (but is not required to) use. This
+ buffer is guaranteed to have space for at least width pixels.
+
+ - A flag indicating whether a8r8g8b8 or a16r16g16b16 pixels should
+ be fetched
+
+ There are a number of (eventual) benefits to the iterators:
+
+ - The initialization of the iterator can be virtualized such that
+ implementations can plug in their own CPU specific get_scanline()
+ and write_back() functions.
+
+ - If an image is horizontal, it can simply plug in an appropriate
+ get_scanline(). This way we can get rid of the annoying
+ classify() virtual function.
+
+ - In general, iterators can remember what they did on the last
+ scanline, so for example a REPEAT_NONE image might reuse the same
+ data for all the empty scanlines generated by the zero-extension.
+
+ - More detailed information can be passed to iterator, allowing
+ more specialized fetchers to be used.
+
+ - We can fix the bug where destination filters and transformations
+ are not currently being ignored as they should be.
+
+ However, this initial implementation is not optimized at all. We lose
+ several existing optimizations:
+
+ - The ability to composite directly in the destination
+ - The ability to only fetch one scanline for horizontal images
+ - The ability to avoid fetching the src and mask for the CLEAR
+ operator
+
+ Later patches will re-introduce these optimizations.

+
+ Fix for potential unaligned memory accesses
+
+ The temporary scanline buffer allocated on stack was declared
+ as uint8_t array. As a result, the compiler was free to select
+ any arbitrary alignment for it (even though there is typically
+ no reason to use really weird alignments here and the stack is
+ normally at least 4 bytes aligned on most platforms). Having
+ improper alignment is non-portable and can impact performance
+ or even make the code misbehave depending on the target platform.
+
+ Using uint64_t type for this array should ensure that any possible
+ memory accesses done by pixman code are going to be handled correctly
+ (pixman-combine64.c can access this buffer via uint64_t * pointer).
+
+ Some alignment related problem was reported in:
+ http://lists.freedesktop.org/archives/pixman/2010-November/000747.html

+ ARM: better NEON instructions scheduling for over_n_8_0565
+
+ Code rearranged to get better instructions scheduling for ARM Cortex-A8/A9.
+ Now it is ~30% faster for the pixel data in L1 cache and makes better use
+ of memory bandwidth when running at lower clock frequencies (ex. 500MHz).
+ Also register d24 (pixels from the mask image) is now not clobbered by
+ supplementary macros, which allows to reuse them for the other variants
+ of compositing operations later.

+ Radial gradients are "conical", thus they can have some non-opaque

+
+ To guarantee that a radial gradient is actually opaque, it needs to

+
+ The performance improvement is only in the ballpark of 5% when
+ compared against C code built with a reasonably good compiler
+ (gcc 4.5.1). But gcc 4.4 produces approximately 30% slower code
+ here, so assembly optimization makes sense to avoid dependency

+
+ ARM: nearest scaling support for NEON scanline compositing functions
+
+ Now it is possible to generate scanline processing functions
+ for the case when the source image is scaled with NEAREST filter.
+
+ Only 16bpp and 32bpp pixel formats are supported for now. But the
+ others can be also added later when needed. All the existing NEON
+ fast path functions should be quite easy to reuse for implementing
+ fast paths which can work with scaled source images.

+
+ ARM: NEON: source image pixel fetcher can be overrided now
+
+ Added a special macro 'pixld_src' which is now responsible for fetching
+ pixels from the source image. Right now it just passes all its arguments
+ directly to 'pixld' macro, but it can be used in the future to provide
+ a special pixel fetcher for implementing nearest scaling.
+
+ The 'pixld_src' has a lot of arguments which define its behavior. But
+ for each particular fast path implementation, we already know NEON
+ registers allocation and how many pixels are processed in a single block.
+ That's why a higher level macro 'fetch_src_pixblock' is also introduced
+ (it's easier to use because it has no arguments) and used everywhere
+ in 'pixman-arm-neon-asm.S' instead of VLD instructions.
+
+ This patch does not introduce any functional changes and the resulting code
+ in the compiled object file is exactly the same.

+
+ Do CPU features detection from 'constructor' function when compiled with gcc
+
+ There is attribute 'constructor' supported since gcc 2.7 which allows
+ to have a constructor function for library initialization. This eliminates
+ an extra branch for each composite operation and also helps to avoid
+ complains from race condition detection tools like helgrind.
+
+ The other compilers may or may not support this attribute properly.
+ Ideally, the compilers should fail to compile the code with unknown
+ attribute, so the configure check should do the right job. But in
+ reality the problems are surely possible. Fortunately such problems
+ should be quite easy to find because NULL pointer dereference should
+ happen almost immediately if the constructor fails to run.
+
+ clang 2.7:
+ supports __attribute__((constructor)) properly and pretends to be gcc
+
+ tcc 0.9.25:
+ ignores __attribute__((constructor)), but does not pretend to be gcc

+
+ Remove workaround for a bug in the 1.6 X server.
+
+ There used to be a bug in the X server where it would rely on
+ out-of-bounds accesses when it was asked to composite with a
+ window as the source. It would create a pixman image pointing
+ to some bogus position in memory, but then set a clip region
+ to the position where the actual bits were.
+
+ Due to a bug in old versions of pixman, where it would not clip
+ against the image bounds when a clip region was set, this would
+ actually work. So when the pixman bug was fixed, a workaround was
+ added to allow certain out-of-bound accesses.
+
+ However, the 1.6 X server is so old now that we can remove this
+ workaround. This does mean that if you update pixman to 0.22 or later,
+ you will need to use a 1.7 X server or later.

+
+ Make classification consistent with rasterization
+
+ Use the same computations to classify the gradient and to
+ rasterize it.
+ This improves the correctness of the classification by
+ avoiding integer division.

+
+ Improve precision of linear gradients
+
+ Integer division (without keeping the remainder) can discard a lot
+ of information. Doing the division maths in floating point (and
+ paying attention to error propagation) allows to greatly improve
+ the precision of linear gradients.

+
+ Draw radial gradients with PDF semantics
+
+ Change radial gradient computations and definition to reflect the
+ radial gradients in PDF specifications (see section 8.7.4.5.4,
+ Type 3 (Radial) Shadings of the PDF Reference Manual).
+
+ Instead of having a valid interpolation parameter value for every
+ point of the plane, define it only for points withing the area
+ covered by the family of circles generated by interpolating or
+ extrapolating the start and end circles.
+
+ Points outside this area are now transparent black (rgba 0 0 0 0).
+ Points within this area have the color assiciated with the maximum
+ value of the interpolation parameter in that point (if multiple
+ solutions exist within the range specified by the extend mode).

+
+ Remove broken optimizations in combine_disjoint_over_u()
+
+ The first broken optimization is that it checks "a != 0x00" where it
+ should check "s != 0x00". The other is that it skips the computation
+ when alpha is 0xff. That is wrong because in the formula:
+
+ min (1, (1 - Aa)/Ab)
+
+ the render specification states that if Ab is 0, the quotient is
+ defined to positive infinity. That is the case even if (1 - Aa) is 0.

+ Delete simple repeat code
+
+ This was supposedly an optimization, but it has pathological cases
+ where it definitely isn't. For example a 1 x n image will cause it to
+ have terrible memory access patterns and to generate a ton of modulus

+
+ Since no one has ever measured whether it actually is an improvement,

+ pipeline, and since with the previous commit it can't be triggered
+ anymore because we now require SAMPLES_COVER_CLIP for regular fast

+
+ Fix bug in FAST_PATH_STD_FAST_PATH
+
+ The standard fast paths deal with two kinds of images: solids and
+ bits. These two image types require different flags, but
+ PIXMAN_STD_FAST_PATH uses the same ones for both.
+
+ This patch makes it so that solid images just get the standard flags,
+ while bits images must be untransformed contain the destination clip
+ within the sample grid.
+
+ This means that the old FAST_PATH_COVERS_CLIP flag is now not used
+ anymore, so it can be deleted.

+ Move aligned_malloc() to utils
+
+ The aligned_malloc() routine will be used in more than one test utility.
+ At least, a low-level blitter benchmark needs it. Therefore, let's make

+
+ There are versions for all combinations of x8r8g8b8/a8r8g8b8 and

+ The new scalers are all commented out, but the next commits will

+ analyze_extents: Fast path for non-transformed BITS images
+
+ Profiling various cairo traces showed that we were spending a lot of
+ time in analyze_extents and compute_sample_extents(). This was
+ especially bad for glyphs where all this computation was completely
+ unnecessary.
+
+ This patch adds a fast path for the case of non-transformed BITS
+ images. The result is approximately a 6% improvement on the
+ firefox-talos-gfx benchmark:
+
+ Before:
+
+ [ # ] backend test min(s) median(s) stddev. count
+ [ 0] image firefox-talos-gfx 13.797 13.848 0.20% 6/6
+
+ After:
+
+ [ # ] backend test min(s) median(s) stddev. count
+ [ 0] image firefox-talos-gfx 12.946 13.018 0.39% 6/6

+ When an image is solid or repeating, the FAST_PATH_COVERS_CLIP flag

+
+ Also the code that turned this flag off in pixman.c was not correct;

+ doesn't set the flag by default, but instead relies on the call to

+
+ This is the first demo implementation, it should be possible to

+
+ PAD repeat support for fast scaling with nearest filter
+
+ When processing pixels from the left and right padding, the same
+ scanline function is used with 'unit_x' set to 0.
+
+ Actually appears that gcc can handle this quite efficiently. When
+ using 'restrict' keyword, it is able to optimize the whole operation
+ performed on left or right padding pixels to a small unrolled loop
+ (the code is reduced to a simple fill implementation):
+
+ 9b30: 89 08 mov %ecx,(%rax)
+ 9b32: 89 48 04 mov %ecx,0x4(%rax)
+ 9b35: 48 83 c0 08 add $0x8,%rax
+ 9b39: 49 39 c0 cmp %rax,%r8
+ 9b3c: 75 f2 jne 9b30
+
+ Without 'restrict' keyword, there is one instruction more: reloading
+ source pixel data from memory in the beginning of each iteration. That
+ is slower, but also acceptable.

+
+ Nearest scaling fast path macro split into two parts
+
+ Scanline processing is now split into a separate function. This provides
+ an easy way of overriding it with a platform specific implementation,
+ which may use SIMD optimizations. Only basic C data types are used as
+ the arguments for this function, so it may be implemented entirely in
+ assembly or be generated by some JIT engine.
+
+ Also as a result of this split, the complexity of code is reduced a
+ bit and now it should be easier to introduce support for the currently
+ missing NONE, PAD and REFLECT repeat types.

+ Be more paranoid about checking for GTK+
+
+ From time to time people run into issues where the configure script

+
+ https://bugs.freedesktop.org/show_bug.cgi?id=29736
+
+ This patch makes the configure script more paranoid by
+
+ - always using PKG_CHECK_MODULES and not PKG_CHECK_EXISTS, since it
+ seems PKG_CHECK_EXISTS will sometimes return true even if a dependency
+ of GTK+, such as pixman-1, is missing.
+
+ - explicitly checking that pixman-1 is installed before enabling GTK+.

+ Introduce new FAST_PATH_SAMPLES_OPAQUE flag
+
+ This flag is set whenever the pixels of a bits image don't have an
+ alpha channel. Together with FAST_PATH_SAMPLES_COVER_CLIP it implies
+ that the image effectively is opaque, so we can do operator reductions
+ such as OVER->SRC.

+
+ Replace compute_src_extent_flags() with analyze_extents()
+
+ This commit fixes two separate problems: 1. Incorrect computation of
+ the FAST_PATH_SAMPLES_COVER_CLIP flag, and 2. FAST_PATH_16BIT_SAFE is
+ a nonsensical thing to compute.
+
+ == 1. Incorrect computation of SAMPLES_COVER_CLIP:
+
+ Previously we were using pixman_transform_bounds() to compute which
+ source samples would be used for a composite operation. This is
+ incorrect for several reasons:
+
+ (a) pixman_transform_bounds() is transforming the integer bounding box
+ of the destination samples, where it should be transforming the
+ bounding box of the samples themselves. In other words, it is too
+ pessimistic in some cases.
+
+ (b) pixman_transform_bounds() is not rounding the same way as we do
+ during sampling. For example, for a NEAREST filter we subtract
+ pixman_fixed_e before rounding off to the nearest sample so that a
+ transformed value of 1 will round to the sample at 0.5 and not to the
+ one at 1.5. However, pixman_transform_bounds() would simply truncate
+ to 1 which would imply that the first sample to be used was the one at
+ 1.5. In other words, it is too optimistic in some cases.
+
+ (c) The result of pixman_transform_bounds() does not account for the
+ interpolation filter applied to the source.
+
+ == 2. FAST_PATH_16BIT_SAFE is nonsensical
+
+ The FAST_PATH_16BIT_SAFE is a flag that indicates that various
+ computations can be safely done within a 16.16 fixed-point
+ variable. It was used by certain fast paths who relied on those
+ computations succeeding. The problem is that many other compositing
+ functions were making similar assumptions but not actually requiring
+ the flag to be set. Notably, all the general compositing functions
+ simply walk the source region using 16.16 variables. If the
+ transformation happens to overflow, strange things will happen.
+
+ So instead of computing this flag in certain cases, it is better to
+ simply detect that overflows will happen and not try to composite at
+ all in that case. This has the advantage that most compositing
+ functions can be written naturally way.
+
+ It does have the disadvantage that we are giving up on some cases that
+ previously worked, but those are all corner cases where the areas
+ involved were very close to the limits of the coordinate
+ system. Relying on these working reliably was always a somewhat
+ dubious proposition. The most important case that might have worked
+ previously was untransformed compositing involving images larger than
+ 32 bits. But even in those cases, if you had REPEAT_PAD or
+ REPEAT_REFLECT turned on, you would hit bits_image_fetch_transformed()
+ which has the 16 bit limitations.
+
+ == Fixes
+
+ This patch fixes both problems by introducing a new function called
+ analyze_extents() that has the responsibility to reject corner cases,
+ and to compute flags based on the extents.
+
+ It does this through a new compute_sample_extents() function that will
+ compute a conservative (but tight) approximation to the bounding box
+ of the samples that will actually be needed. By basing the computation
+ on the positions of the _sample_ locations in the destination, and by
+ taking the interpolation filter into account, it fixes problem one.
+
+ The same function is also used with a one-pixel expanded version of
+ the destination extents. By checking if the transformed bounding box
+ will overflow 16.16 fixed point, it fixes problem two.

+
+ Extend scaling-crash-test in various ways
+
+ This extends scaling-crash-test to test some more things:
+
+ - All combinations of NEAREST/BILINEAR/CONVOLUTION filters and
+ NORMAL/PAD/REFLECT repeat modes.
+
+ - Tests various scale factors very close to 1/7th such that the source
+ area is very close to edge of the source image.
+
+ - The same things, only with scale factors very close to 1/32767th.
+
+ - Enables the commented-out tests for accessing memory outside the
+ source buffer.
+
+ Also there is now a border around the source buffer which has a
+ different color than the source buffer itself so that if we sample
+ outside, it will show up.
+
+ Finally, the test now allows the destination buffer to not be changed
+ at all. This allows pixman to simply bail out in cases where the
+ transformation too strange.

+
+ Fix conical gradients to match QConicalGradient from Qt
+
+ Under the assumption that pixman gradients are supposed to match
+ QConicalgradient, described here:
+
+ http://doc.trolltech.com/4.4/qconicalgradient.html
+
+ this patch fixes two separate bugs in pixman-conical-gradient.c.
+
+ The first bug is that the output of atan2() is in the range of [-pi,
+ pi], which means the parameter into the gradient can be negative. This
+ is wrong since a QConicalGradient always interpolates around the
+ center from 0 to 1. The fix for that is to (a) make sure the given
+ angle is between 0 and 360, and (b) add or subtract 2 * M_PI if the
+ computed angle ends up outside [0, 2 * pi].
+
+ The other bug is that we were interpolating clockwise, whereas
+ QConicalGradient calls for a counter-clockwise interpolation. This is
+ easily fixed by subtracting the parameter from 1.
+
+ Finally, this patch encapsulates the computation in a new force-inline
+ function so that it can be reused in both the affine and non-affine
+ case.

+
+ Eliminate mask_bits from all the scanline fetchers.
+
+ Back in the day, the mask_bits argument was used to distinguish
+ between masks used for component alpha (where it was 0xffffffff) and
+ masks for unified alpha (where it was 0xff000000). In this way, the
+ fetchers could check if just the alpha channel was 0 and in that case
+ avoid fetching the source.
+
+ However, we haven't actually used it like that for a long time; it is
+ currently always either 0xffffffff or 0 (if the mask is NULL). It also
+ doesn't seem worthwhile resurrecting it because for premultiplied
+ buffers, if alpha is 0, then so are the color channels
+ normally.
+
+ This patch eliminates the mask_bits and changes the fetchers to just
+ assume it is 0xffffffff if mask is non-NULL.

+
+ ARM: Workaround for a NEON bug in assembler from binutils 2.18
+
+ The problem was reported as bug 25534 against pixman in
+ freedesktop.org bugzila. Link to a patch for binutils:
+ http://sourceware.org/ml/binutils/2008-03/msg00260.html
+
+ For pixman the impact is a build failure when using
+ binutils 2.18. Versions 2.19 and higer are fine. Still
+ some distros may be using older versions of binutils and
+ this is causing problems.
+
+ This patch workarounds the problem by replacing a problematic
+ "vmov a, b" instruction with equivalent "vorr a, b, b". Actually
+ they even map to the same instruction opcode in the generated
+ code, so the resulting binary is identical with and without patch.

+
+ ARM: Use '.object_arch' directive in NEON assembly file
+
+ This can be used to override the architecture recorded in the EABI object
+ attribute section. We set a minimum arch to 'armv4'. Binutils documentation
+ recommends to use this directive with the code performing runtime detection
+ of CPU features.
+
+ Additionally NEON/VFP EABI attributes are suppressed. And the instruction
+ set to use is explicitly set to '.arm'.
+
+ Configure test for NEON support is also updated to include a bunch of
+ these new directives (if any of these is unsupported by the assembler,
+ it is better to fail configure test than to fail library build).
+
+ All these changes are required to fix SIGILL problem on armv4t, reported in
+ http://lists.freedesktop.org/archives/pixman/2010-March/000123.html

+
+ Add specialized fast nearest scalers

+Date: Fri Mar 12 15:41:01 2010 +0100
+
+ Add FAST_PATH_SAMPLES_COVER_CLIP and FAST_PATH_16BIT_SAFE
+
+ FAST_PATH_SAMPLES_COVER_CLIP:
+
+ This is set of the source sample grid, unrepeated but transformed
+ completely completely covers the clip destination. If this is set
+ you can use a simple scaled that doesn't have to care about the repeat
+ mode.
+
+ FAST_PATH_16BIT_SAFE:
+
+ This signifies two things:
+ 1) The size of the src/mask fits in a 16.16 fixed point, so something like:
+
+ max_vx = src_image->bits.width << 16;
+
+ Is allowed and is guaranteed to not overflow max_vx
+
+ 2) When stepping the source space we're guaranteed to never overflow
+ a 16.16 bit fix point variable, even if we step one extra step
+ in the destination space. This means that a loop doing:
+
+ x = vx >> 16;
+ vx += unit_x; d = src_row[x];
+
+ will never overflow vx causing x to be negative.
+
+ And additionally, if you track vx like above and apply NORMAL repeat
+ after the vx addition with something like:
+
+ while (vx >= max_vx) vx -= max_vx;
+
+ This will never overflow the vx even on the final increment that
+ takes vx one past the end of where we will read, which makes the
+ repeat loop safe.

+ This fixes blitters-test on big-endian machines.

+
+ Store the operator table more compactly.
+
+ The four cases for each operator:
+
+ none-are-opaque, src-is-opaque, dest-is-opaque, both-are-opaque
+
+ are packed into one uint32_t per operator. The relevant strength
+ reduced operator can then be found by packing the source-is-opaque and
+ dest-is-opaque into two bits and shifting that number of bytes.
+
+ Chris Wilson pointed out a bug in the original version of this commit:
+ dest_is_opaque and source_is_opaque were used as booleans, but their
+ actual values were the results of a logical AND with the
+ FAST_PATH_OPAQUE flag, so the shift value was wildly wrong.
+
+ The only reason it actually passed the test suite (on x86) was that
+ the compiler computed the shift amount in the cl register, and the low
+ byte of FAST_PATH_OPAQUE happens to be 0, so no shifting actually took
+ place, and the original operator was returned.

+
+ Make the operator strength reduction constant time.
+
+ By extending the operator information table to cover all operators we
+ can replace the loop with a table look-up. At the same time, base the
+ operator optimization on the computed flags rather than the ones in
+ the image struct.
+
+ Finally, as an extra optimization, we no longer ignore the case where
+ there is a mask. Instead we consider the source opaque if both source
+ and mask are opaque, or if the source is opaque and the mask is
+ missing.

+
+ Move all code to do debugging spew into pixman-private.
+
+ Rather than the region code having its own little debug system, move
+ all of it into pixman-private where there is already return_if_fail()
+ macros etc. These macros are now enabled in development snapshots and
+ nowhere else. Previously they were never enabled unless you modified
+ the code.
+
+ At the same time, remove all the asserts from the region code since we
+ can never turn them on anyway, and replace them with
+ critical_if_fail() macros that will print spew to standard error when
+ DEBUG is defined.
+
+ Finally, also change the debugging spew in pixman-bits-image.c to use
+ return_val_if_fail() instead of its own fprintf().

+ Eliminate all the composite methods.

+ They are no longer necessary because we will just walk the fast path

+
+ Make general_composite_rect() just another fast path.
+
+ We introduce a new PIXMAN_OP_any fake operator and a PIXMAN_any fake
+ format that match anything. Then general_composite_rect() can be used
+ as another fast path.
+
+ Because general_composite_rect() does not require the sources to cover
+ the clip region, we add a new flag FAST_PATH_COVERS_CLIP which is part
+ of the set of standard flags for fast paths.
+
+ Because this flag cannot be computed until after the clip region is
+ available, we have to call pixman_compute_composite_region32() before
+ checking for fast paths. This will resolve itself when we get to the
+ point where _pixman_run_fast_path() is only called once per composite
+ operation.

+ When fetching from an alpha map, replace the alpha channel of the image
+
+ Previously it would be multiplied onto the image pixel, but the Render
+ specification is pretty clear that the alpha map should be used
+ *instead* of any alpha channel within the image.
+
+ This makes the assumption that the pixels in the image are already
+ premultiplied with the alpha channel from the alpha map. If we don't
+ make this assumption and the image has an alpha channel of its own, we
+ would have to first unpremultiply that pixel, and then premultiply the
+ alpha value onto the color channels, and then replace the alpha
+ channel.

+
+ This program demonstrates three bugs relating to alpha maps:
+
+ - When fetching from an alpha map into 32 bit intermediates, we use
+ the fetcher from the image, and not the one from the alpha map.
+
+ - For 64 bit intermediates we call fetch_pixel_generic_lossy_32()
+ which then calls fetch_pixel_raw_64, which is NULL because alpha
+ images are never validated.
+
+ - The alpha map should be used *in place* of any existing alpha
+ channel, but we are actually multiplying it onto the image.

+
+ region: Enable or disable fatal errors and selfchecks based on version number
+
+ There is a couple of bugs in bugzilla where bugs in the X server
+ triggered asserts in the pixman region code. It is probably better to
+ let the X server survive this. (In fact, I thought I had disabled them
+ for 0.16.0, but apparently not).
+
+ The patch below uses these rules:
+
+ - In _stable_ pixman releases, assertions and selfchecks are turned
+ off. Assertions, so that the X server doesn't die. Selfchecks,
+ for performance reasons.
+
+ - In _unstable_ pixman releases, both assertions and selfcheck are
+ turned on. These releases are what get added to development
+ distributions such as rawhide, so we want as much self-checking
+ as possible.
+
+ - In _random git checkouts_, assertions are enabled, so that bugs
+ are caught, but selfchecks are disabled so that you can use them
+ for performance work without having to fiddle with turning
+ selfchecks off.

+
+ Existing template already supports 2D images processing,

+
+ Fix rounding of top and bottom coordinates.
+
+ The rules for trap rasterization is that coordinates are rounded
+ towards north-west.
+
+ The pixman_sample_ceil() function is used to compute the first
+ (top-most) sample row included in the trap, so when the input
+ coordinate is already exactly on a sample row, no rounding should take
+ place.
+
+ On the other hand, pixman_sample_floor() is used to compute the final
+ (bottom-most) sample row, so if the input is precisely on a sample
+ row, it needs to be rounded down to the previous row.
+
+ This commit fixes the rounding computation. The idea of the
+ computation is like this:
+
+ Floor operation that rounds exact matches down: First subtract
+ pixman_fixed_e to make sure input already on a sample row gets rounded
+ down. Then find out how many small steps are between the input and the
+ first fraction. Then add those small steps to the first fraction.
+
+ The ceil operation first adds (small_step + pixman_e), then runs a
+ floor. This ensures that exact matches are not rounded off.
+
+ Based on a patch by M Joonas Pihlaja.

+
+ Fix slightly skewed sampling grid for antialiased traps
+
+ The sampling grid is slightly skewed in the antialiased case. Consider
+ the case where we have n = 8 bits of alpha.
+
+ The small step is
+
+ small_step = fixed_1 / 15 = 65536 / 15 = 4369
+
+ The first fraction is then
+
+ frac_first = (small_step / 2) = (65536 - 15) / 2 = 2184
+
+ and the last fraction becomes
+
+ frac_last
+ = frac_first + (15 - 1) * small_step = 2184 + 14 * 4369 = 63350
+
+ which means the size of the last bit of the pixel is
+
+ 65536 - 63350 = 2186
+
+ which is 2 bigger than the first fraction. This is not the end of the
+ world, but it would be more correct to have 2185 and 2185, and we can
+ accomplish that simply by making the first fraction half the *big*
+ step instead of half the small step.
+
+ If we ever move to coordinates with 8 fractional bits, the
+ corresponding values become 8 and 10 out of 256, where 9 and 9 would
+ be better.
+
+ Similarly in the X direction.

+
+ Eliminate the NEED_SOLID_MASK flag
+
+ This flag was used to indicate that the mask was solid while still
+ allowing a specific format to be required. However, there is not
+ actually any need for this because the fast paths all used
+ _pixman_image_get_solid() which already allowed arbitrary formats.
+
+ The one thing that had to be dealt with was component alpha. In
+ addition to interpreting the presence of the NEED_COMPONENT_ALPHA
+ flag, we now also interprete the *absence* of this flag as a
+ requirement that the mask does *not* have component alpha.
+
+ Siarhei Siamashka pointed out that the first version of this commit
+ had a bug, in which a NEED_SOLID_MASK was accidentally not turned into
+ a PIXMAN_solid in the ARM NEON implementation.

+
+ Use the destination buffer directly in more cases instead of fetching.
+
+ When the destination buffer is either a8r8g8b8 or x8r8g8b8, we can use
+ it directly instead of fetching into a temporary buffer. When the
+ format is x8r8g8b8, we require the operator to not make use of
+ destination alpha, but when it is a8r8g8b8, there are no restrictions.

+ ARM: Remove fallback to ARMv6 implementation from NEON delegate chain
+
+ This can help to fix build problems with '-mthumb' gcc option in CFLAGS.
+ ARMv6 optimized code can't be compiled for thumb (because of its inline

+
+ Every ARMv6 optimized fast path function also has a better NEON

+ delegate chain should additionally result in a bit better performance.

+
+ Test program for stressing the use of different formats and operators
+
+ The code and overall method is mostly based on scaling-test. This one
+ focuses on trying to stress as many different color formats and types
+ of composition operations as possible.
+
+ This is an initial implementation which may need more tuning. Also
+ not all color format and operator combinations are actually used.
+
+ When cpu specific optimizations are disabled, this test provides
+ identical deterministic results on x86, PPC and ARM.
+
+ Script blitters-test-bisect.rb now works in non-stop mode, until
+ it finds any problem. This allows to run it for example overnight
+ in order to test a lot more variants of pixman calls and increase
+ chances of detecting problems in pixman. Just like with scaling-test,
+ running blitters-test binary alone with no command line arguments
+ runs a small predefined number of tests and compares checksum
+ with a reference value for quick verification.

+
+ Make pix_add_mul() in pixman-mmx.c produce exact results.
+
+ Previously this routine would compute (x * a + y * b) / 255. Now it
+ computes (x * a) / 255 + (y * b) / 255, so that the results are
+ bitwise equivalent to the non-mmx versions.

+
+ Rewrite the two-component arithmetic macros.
+
+ Previously they were not bit-for-bit equivalent to the one-component
+ versions. The new code is also simpler and easier to read because it
+ factors out some common sub-macros.
+
+ The x * a + y * b macro now only uses four multiplications - the
+ previous version used eight.

+ Add implementation of MMX __m64 functions for MSVC x64.
+
+ Microsoft C++ does not define __m64 and all related MMX functions in
+ x64. However, it succeeds in generating object files for SSE2 code
+ inside pixman.
+
+ The real problem happens during linking, when it cannot find MMX functions
+ (which are not defined as intrinsics for AMD64 platform).
+
+ I have implemented those missing functions using general programming.
+
+ MMX __m64 is used relatively scarcely within SSE2 implementation, and the
+ performance impact probably is negligible.

+ Only apply the workaround if the clip region extends beyond the drawable.
+
+ This works because the X server always attempts to set a clip region
+ within the bounds of the drawable, and it only fails at it when it is
+ computing the wrong translation and therefore needs the workaround.

+
+ Rework the workaround for bogus X server images.
+
+ Bug 22844 demonstrates that it is not sufficient to play tricks with
+ the clip regions to work around the bogus images from the X
+ server. The problem there is that if the operation hits the general
+ path and the destination has a different format than a8r8g8b8, the
+ destination pixels will be fetched into a temporary array. But because
+ those pixels would be outside the clip region, they would be fetched
+ as black. The previous workaround was relying on fast paths fetching
+ those pixels without checking the clip region.
+
+ In the new scheme we work around the problem at the
+ pixman_image_composite() level. If an image is determined to need a
+ work around, we translate both the bits pointer, the coordinates, and
+ the clip region, thus effectively undoing the X server's broken

+ Fix NEON build for older ARM CPUs
+
+ The pld instruction used in the NEON assembler code is only available

+
+ Set -mcpu=cortex-a8 when compiling the source file (similar to what is
+ already done for the SIMD build).

+ ARM: Workaround cs2007q3 compiler bug for NEON registers clobber list
+
+ 128-bit registers "qX" are incorrectly handled in inline assembly
+ clobber list for codesourcery cs2007q3 gcc toolchain. Only the
+ first 64-bit half is saved and restored by gcc. Changing clobber
+ list to use only 64-bit register aliases can solve this problem.
+ For example, 128-bit register q0 is mapped to two 64-bit
+ registers d0 and d1, q1 is mapped to d2 and d3, etc.

+ Add a lot more sanity checks to region code
+
+ - Introduce a GOOD_RECT() macro that checks that a pixman_box_t is not
+ empty or degenerate an use it.
+ - Use GOOD_RECT() instead of magic if statements for funtions that take
+ x, y, width, height arguments
+ - Use GOOD_RECT() in _reset(). The checks in the previous code seemed to
+ allow an empty box, but then created a broken region from it.
+ - Add GOOD(region) check at the end of _translate()

+
+ Add workarounds for X servers doing out-of-bounds accesses.
+
+ Old X servers rely on out-of-bounds accesses when they are asked
+ to composite with a window as the source. They create a pixman image
+ pointing to some bogus position in memory, but then they set a clip
+ region to the position where the actual bits are.
+
+ Due to a bug in old versions of pixman, where it would not clip
+ against the image bounds when a clip region was set, this would
+ actually work.
+
+ The workaround added by this commit is to try and detect whether a
+ source drawable is actually a window without a client clip set. Such a
+ window will generally have a clip region that corresponds exactly to
+ the hierarchy clip in the server, whereas pixmaps will have a clip
+ region that is an exact match to the drawable.
+
+ When we detect such a window, we allow a fast path to run that would
+ normally be rejected due to the sources not completely subsuming the
+ composite region.
+
+ Fixed X servers should call the new function
+ pixman_disable_out_of_bounds_workaround() to disable the workaround.
+
+ This was reported in bug 22484.

+
+ Update the CRC value in scaling-test.c.
+
+ The changes in pixman behavior justifying this are:
+
+ - New clipping rules
+
+ - Bug fixes in region code. In particular, when
+ pixman_region_init_rects() is called on these two boxes:
+
+ { 2, 6, 7, 6 }
+ { 4, 1, 6, 7 }
+
+ it now ignores the first one, which is empty and produces
+
+ { 4, 1, 6, 7 }
+
+ Previously, it would produce:
+
+ { 2, 1, 7, 7 }
+
+ for some reason.

+
+ Fix offset bug in pixman_run_fast_path().
+
+ Fast paths should only run when the source images complete cover the
+ composite region, because otherwise they would be required to sample
+ the border, and fast paths generally don't know how to do that.
+
+ The check for this did not work right because it didn't take the
+ offset generated by the composite coordinates into account. This
+ commits fixes that by adding (x, y) coordinates to image cover
+ indicating the new position of the source in destination coordinates.
+
+ Based on this we now compare against the region extents which are
+ already in destination coordinates.

+ Remove redundant NULL checks from general_composite_rect().
+
+ The general_composite_rect() function has two invocations
+ of the return_if_fail() macro before any of its variable
+ declarations. Removing them allows for compilation to
+ succeed using a pre-C99 compiler.

+
+ [NEON] Add transparent rect blitter.
+
+commit 8eeeca993252edc39da9c5c57545b81215fafc81
+Author: Jonathan Morton <jmorton@sd070.hel.movial.fi>
+Date: Tue Jun 16 12:08:29 2009 -0400
+
+ [NEON] Replace Ian's glyph-blitter with a better one.
+
+ Each scanline of the destination is bulk-loaded into a cached buffer on
+ the stack (using the QuadWordCopy routine) before being processed. This
+ is the primary benefit on uncached framebuffers, since it is necessary
+ to minimise the number of accesses to such things and avoid
+ write-to-read turnarounds.
+
+ This also simplifies edge handling, since QuadWordCopy() can do a
+ precise writeback efficiently via the write-combiner, allowing the main
+ routine to "over-read" the scanline edge safely when required. This is
+ why the glyph's mask data is also copied into a temporary buffer of
+ known size.
+
+ Each group of 8 pixels is then processed using fewer instructions,
+ taking advantage of the lower precision requirements of the 6-bit
+ destination (so a simpler pixel multiply can be used) and using a more
+ efficient bit-repacking method.
+
+ (As an aside, this patch removes nearly twice as much code as it
+ introduces. Most of this is due to duplication of Ian's inner loop,
+ since he has to handle narrow cases separately. RVCT support is of
+ course preserved.)
+
+ We measured the doubling of performance by rendering 96-pixel height
+ glyph strings, which are fillrate limited rather than latency/overhead
+ limited. The performance is also improved, albeit by a smaller amount,
+ on the more usual smaller text, demonstrating that internal overhead is
+ not a problem.

+
+ Simplify clipping rule
+
+ The new rule is:
+
+ - Output is clipped to the destination clip region.
+
+ - If a source image has the clip_sources property set, then there
+ is an additional step, after repeating and transforming, but before
+ compositing, where pixels that are not in the source clip are
+ rejected. Rejected means no compositing takes place (not that the
+ pixel is treated as 0). By default source clipping is turned off;
+ when they are turned on, only client-set clips are honored.
+
+ The old rules were unclear and inconsistently implemented.

+ pixman: define pixman_have_{mmx,sse2} on 64-bit Linux
+
+ The refactoring of pixman removed pixman-sse2.h and pixman-mmx.h in commit
+ 41a9a17e0308f2075bb1bd59c4411e43a67d49ec
+ (http://cgit.freedesktop.org/pixman/commit/?id=41a9a17e0308f2075bb1bd59c4411e43a67d49ec).
+ On 64-bit Linux this breaks linking of new programs as well as execution of
+ existing programs with the following errors:
+
+ ../pixman/.libs/libpixman-1.so: undefined reference to `pixman_have_mmx'
+ ../pixman/.libs/libpixman-1.so: undefined reference to `pixman_have_sse2'
+
+ This patch fixes the issue for me by re-introducing the definitions for these
+ functions. It might be preferable, though, to create proper trivial static
+ inline functions instead.

+ Fix alpha map computation in pixman_compute_composite_region()
+
+ According to the RENDER spec, the origin of the alpha map is
+ interpreted relative to the origin of the drawable of the image, not
+ the origin of the drawable of the alpha map.
+
+ This commit fixes that and adds an alpha-test.c test program.
+
+ The only use of alpha maps I have been able to find is in Qt and they
+ don't use a non-zero alpha origin.

+ Fix overflows during trap rasterization. [Bug 16560].
+
+ Avoid overflows when rasterizing traps that fall entirely in the space
+ between the final sample row and the end of the coordinate system, or
+ in the space between the beginning of the coordinate system and the
+ first sample row. Such traps don't contain any sample points, so the
+ top and bottom of the edges can safely be moved to the beginning/end.

+ Fixed rendering bug for source alpha == 0 in OVER fastpath functions
+
+ Handling of the case when source alpha is zero was keeping destination

+ For example fbOver(0x00200483, 0x9CAC7E9F) == 0x9CCC82FF and the
+ destination pixel changes from 0x9CAC7E9F to 0x9CCC82FF in spite
+ of having zero alpha.

+ a PASS/FAIL verdict based on the precalculated crc32 value
+ for using pixman with all the fastpath functions disabled,

+
+ Set srcRepeat = False when using fbCompositeSrcScaleNearest
+
+ NORMAL repeat was broken (the optimized function can handle repeat operation
+ itself and can be screwed up if 'pixman_walk_composite_region' tries to help it
+ by splitting the work into handling multiple separate areas).
+
+ Splitting work into handling different areas does not work right for the
+ transform case (and it is never used for generic path). The point is that this
+ splitting only has full pixel precision at the moment, while correct blitting
+ needs to preserve some fractional part in calculations when moving from one
+ "tile" to another.

+ Add a special case for a source transformation that is only a scale and
+ preserves rectangular pixels and doesn't rotate the image. Currently, only
+ SOURCE is special cased, however I plan to do more work in this area as needed.
+ The biggest advantage the specialization currently has is writing directly to
+ the destination surface instead of a temporary scanline buffer. However, it is
+ still pretty unoptimized but I want to keep things simple for now.

+
+ Unify scanline buffer types
+
+ Change the type of the stack based scanline buffer to uint8_t to match the rest
+ of the variables. Also premultiply the scanline buffer size by sizeof(uint32_t)
+ because the bpp can be either sizeof(uint32_t) or sizeof(uint64_t).

+ Rename the current ARM code to ARM SIMD
+
+ This code is only for CPUs supporting the SIMD instructions, not for all ARM
+ CPUs.
+
+ I stumbled above the recent commit with the ARM SIMD code while preparing a
+ patch that models the patch from #13445 after the MMX and SSE2 cases:
+
+ The ARM SIMD option currently uses --disable-arm, although this code is only
+ for CPUs >= ARMv6. That's as if one would call the option to disable the SSE2
+ code --disable-x86.
+
+ This patch therefore renames the configure option and the function and file
+ names to arm-simd/arm_simd.

+ Move _mm_empty() to correct place
+
+ The "fbComposeSetupSSE2()" function is guarding most of its code
+ depending on the capabilities of the CPU, but unfortunately the call
+ to "_mm_empty()" is not part of this code path but executed
+ unconditionally. This results in a "illegal instruction" crash on
+ non-MMX / non-SSE capable CPUs caused by the the "emms" instruction
+ (embedded in "_mm_empty()").
+
+ Fix bug 17729.

+ There was significant performance overhead associated with indirect

+
+ Also, the old code assumed that if the number of rectangles in the

+ whenever the source clip is different from pict->common.full_region.
+
+ Based on a patch from Antoine Azar.

+
+ Add a lossy 32-bit generic pixel fetch function for wide surfaces.
+
+ The transformed fetch path currently only works at 32-bit precision. Until a
+ wide version of that function is added, we need to have a path to perform a
+ wide FetchPixel and then contract it down to a8r8g8b8.
+
+ Also, use the right format when expanding the result in fbFetchTransformed64.
+ fbFetchTransformed returns a8r8g8b8 results.

+
+ Add wide source picture, external alpha, and transformed image routines.
+
+ The wide external alpha path should work correctly with wide formats. The wide
+ transformed fetch code for now just does a 32-bit fetch and then expands, which
+ will lose precision. Source pictures, for now, are evaluated at depth 32 and
+ then are expanded to depth 64. We could get higher precision by evaluating them
+ directly at depth 64, but this should be good enough for now.

+ Work around GCC bug causing crashes in Mozilla with SSE2

+ When using SSE2 intrinsics, gcc assumes that the stack is 16 byte

+
+ The __force_align_arg_pointer__ makes gcc generate a prologue that

+
+ Fix the SSE related AMD64 build breakage
+
+ The introduction of pixman_have_sse() copied the #ifdef __amd64__
+ found around pixman_have_mmx() in pixman-mmx.c but didn't include the
+ equivalents of the macros in pixman-mmx.h. As a result, the AMD64 link
+ fails because the pixman_have_sse() function doesn't exist.
+
+ I also introduced header inclusion guards to pixman-mmx.h and
+ pixman-sse.h while I was at it.

+
+ Add rounding epsilon for NEAREST filter after transformation, not before.
+
+ For nearest filtering, the transformed location must be rounded to the
+ nearest sample. For locations that precisely in the middle between two
+ samples, we round down by adding -epsilon to the coordinates.
+
+ Before, we would do this on untransformed coordinates. This patch
+ changes it to happen after transformation. It also clarifies the
+ difference between sample locations and rounding.
+
+ Reported by Robert O'Callahan.

+ rasterize traps that extend outside of the image bounds correctly
+
+ Traps that extend outside of the image bounds are rasterized incorrectly
+ currently; the problem is a signed vs. unsigned comparison that got
+ introduced when a width parameter went from int -> uint. This patch
+ puts it back to int (since it's stored as an int in the bits structure
+ to begin with), and also fixes a similar warning in the memset wrapper

+ Use the general code in some cases even when a fast path is available

+ If src or mask are repeating 1x1 images and srcRepeat or

+ 1x1 requests, we just use the general code (which does

+Here are the steps to follow to create a new pixman release:
+
+1) Ensure that there are no uncommitted changes or unpushed commits,
+ and that you are up to date with the latest commits in the central
+ repository. Here are a couple of useful commands:
+
+ git diff (no output)
+
+ git status (should report "nothing to commit")
+
+ git log master...origin (no output; note: *3* dots)
+
+2) Increment pixman_(major|minor|micro) in configure.ac according to
+ the directions in that file.
+
+3) Make sure that new version works, including
+
+ - make distcheck passes
+
+ - the X server still works with the new pixman version
+ installed
+
+ - the cairo test suite hasn't gained any new failures compared
+ to last pixman version.
+
+4) Use "git commit" to record the changes made in step 2 and 3.
+
+5) Generate and publish the tar files by running
+
+ make PREV=<last version> GPGKEY=<your gpg key id> release-publish
+
+ If your freedesktop user name is different from your local one,
+ then also set the variable USER to your freedesktop user name.
+
+6) Run
+
+ make release-publish-message
+
+ to generate a draft release announcement. Edit it as appropriate and
+ send it to
+
+ cairo-announce@cairographics.org
+
+ pixman@lists.freedesktop.org
+
+ xorg-announce@lists.freedesktop.org
+
+7) Increment pixman_micro to the next larger (odd) number in
+ configure.ac. Commit this change, and push all commits created
+ during this process using
+
+ git push
+ git push --tags
+
+ You must use "--tags" here; otherwise the new tag will not
+ be pushed out.
+
+8) Change the topic of the #cairo IRC channel on freenode to advertise
+ the new version.

+*** General notes about rounding
+
+Suppose a function is sampled at positions [k + o] where k is an
+integer and o is a fractional offset 0 <= o < 1.
+
+To round a value to the nearest sample, breaking ties by rounding up,
+we can do this:
+
+ round(x) = floor(x - o + 0.5) + o
+
+That is, first subtract o to let us pretend that the samples are at
+integer coordinates, then add 0.5 and floor to round to nearest
+integer, then add the offset back in.
+
+To break ties by rounding down:
+
+ round(x) = ceil(x - o - 0.5) + o
+
+or if we have an epsilon value:
+
+ round(x) = floor(x - o + 0.5 - e) + o
+
+To always round *up* to the next sample:
+
+ round_up(x) = ceil(x - o) + o
+
+To always round *down* to the previous sample:
+
+ round_down(x) = floor(x - o) + o
+
+If a set of samples is stored in an array, you get from the sample
+position to an index by subtracting the position of the first sample
+in the array:
+
+ index(s) = s - first_sample
+
+
+*** Application to pixman
+
+In pixman, images are sampled with o = 0.5, that is, pixels are
+located midways between integers. We usually break ties by rounding
+down (i.e., "round towards north-west").
+
+
+-- NEAREST filtering:
+
+The NEAREST filter simply picks the closest pixel to the given
+position:
+
+ round(x) = floor(x - 0.5 + 0.5 - e) + 0.5 = floor (x - e) + 0.5
+
+The first sample of a pixman image has position 0.5, so to find the
+index in the pixel array, we have to subtract 0.5:
+
+ floor (x - e) + 0.5 - 0.5 = floor (x - e).
+
+Therefore a 16.16 fixed-point image location is turned into a pixel
+value with NEAREST filtering by doing this:
+
+ pixels[((y - e) >> 16) * stride + ((x - e) >> 16)]
+
+where stride is the number of pixels allocated per scanline and e =
+0x0001.
+
+
+-- CONVOLUTION filtering:
+
+A convolution matrix is considered a sampling of a function f at
+values surrounding 0. For example, this convolution matrix:
+
+ [a, b, c, d]
+
+is interpreted as the values of a function f:
+
+ a = f(-1.5)
+ b = f(-0.5)
+ c = f(0.5)
+ d = f(1.5)
+
+The sample offset in this case is o = 0.5 and the first sample has
+position s0 = -1.5. If the matrix is:
+
+ [a, b, c, d, e]
+
+the sample offset is o = 0 and the first sample has position s0 =
+-2.0. In general we have
+
+ s0 = (- width / 2.0 + 0.5).
+
+and
+
+ o = frac (s0)
+
+To evaluate f at a position between the samples, we round to the
+closest sample, and then we subtract the position of the first sample
+to get the index in the matrix:
+
+ f(t) = matrix[floor(t - o + 0.5) + o - s0]
+
+Note that in this case we break ties by rounding up.
+
+If we write s0 = m + o, where m is an integer, this is equivalent to
+
+ f(t) = matrix[floor(t - o + 0.5) + o - (m + o)]
+ = matrix[floor(t - o + 0.5 - m) + o - o]
+ = matrix[floor(t - s0 + 0.5)]
+
+The convolution filter in pixman positions f such that 0 aligns with
+the given position x. For a given pixel x0 in the image, the closest
+sample of f is then computed by taking (x - x0) and rounding that to
+the closest index:
+
+ i = floor ((x0 - x) - s0 + 0.5)
+
+To perform the convolution, we have to find the first pixel x0 whose
+corresponding sample has index 0. We can write x0 = k + 0.5, where k
+is an integer:
+
+ 0 = floor(k + 0.5 - x - s0 + 0.5)
+
+ = k + floor(1 - x - s0)
+
+ = k - ceil(x + s0 - 1)
+
+ = k - floor(x + s0 - e)
+
+ = k - floor(x - (width - 1) / 2.0 - e)
+
+And so the final formula for the index k of x0 in the image is:
+
+ k = floor(x - (width - 1) / 2.0 - e)
+
+Computing the result is then simply a matter of convolving all the
+pixels starting at k with all the samples in the matrix.
+
+
+--- SEPARABLE_CONVOLUTION
+
+For this filter, x is first rounded to one of n regularly spaced
+subpixel positions. This subpixel position determines which of n
+convolution matrices is being used.
+
+Then, as in a regular convolution filter, the first pixel to be used
+is determined:
+
+ k = floor (x - (width - 1) / 2.0 - e)
+
+and then the image pixels starting there are convolved with the chosen
+matrix. If we write x = xi + frac, where xi is an integer, we get
+
+ k = xi + floor (frac - (width - 1) / 2.0 - e)
+
+so the location of k relative to x is given by:
+
+ (k + 0.5 - x) = xi + floor (frac - (width - 1) / 2.0 - e) + 0.5 - x
+
+ = floor (frac - (width - 1) / 2.0 - e) + 0.5 - frac
+
+which means the contents of the matrix corresponding to (frac) should
+contain width samplings of the function, with the first sample at:
+
+ floor (frac - (width - 1) / 2.0 - e) + 0.5 - frac
+
+This filter is called separable because each of the k x k convolution
+matrices is specified with two k-wide vectors, one for each dimension,
+where each entry in the matrix is computed as the product of the
+corresponding entries in the vectors.
