A new pixman release 0.19.2 is now available. This is a development
snapshot leading up to a stable 0.20.0 release.
News:
- Gradient improvements [Andrea Canciani, Soren Sandmann]
- Altivec detection on OpenBSD [Brad Smith]
- Improved configure-time detection of pthreads [M Joonas Pihlaja]
- Support for x14r6g6b6 format [Marek Vasut]
- Improvements to the test suite [Siarhei Siamashka]
- NEON based combiner for OUT_REVERSE operator [Siarhei]
- Improvements to the SSE2 implementation [Soren]
- Alpha map loops are now caught before they can cause problems [Soren]
- Apply operator strength reduction in more cases [Soren]
Plus bug fixes and some internal reorganisation [Jeff Muizelaar,
Siarhei, Siddarth Agarwal, Soren].

tag: pixman-0.19.2
Log:
Andrea Canciani (2):
support single-stop gradients
test: verify that gradients do not crash pixman
Brad Smith (1):
Add support for AltiVec detection for OpenBSD/PowerPC.
Jeff Muizelaar (3):
Add missing HAVE_CONFIG_H guards for config.h inclusion
Add support for compiling pixman without thread/tls support
create getter for component alpha
M Joonas Pihlaja (6):
Try harder to find suitable flags for pthreads.
Don't trust OpenBSD's gcc to produce working code for __thread.
Check that the OpenMP pragmas don't cause link errors.
Check for specific flags by actually trying to compile and link.
Avoid trailing slashes on automake install dirs.
Fix thinko in configure.ac's macro to test linking.
Marek Vasut (1):
Add support for 32bpp X14R6G6B6 format.
Siarhei Siamashka (9):
test: main loop from blitters-test added as a new function to utils.c
test: blitters-test-bisect.rb converted to perl
test: blitters-test updated to use new fuzzer_test_main() function
test: scaling-test updated to use new fuzzer_test_main() function
test: added OpenMP support for better utilization of multiple CPU cores
test: 'scaling-crash-test' added
test: 'scaling-test' updated to provide better coverage
Code simplification (no need advancing 'vx' at the end of
scanline)
ARM: 'neon_combine_out_reverse_u' combiner
Siddharth Agarwal (1):
Visual Studio 2010 includes stdint.h
S?ren Sandmann Pedersen (57):
Post-release version bump to 0.19.1
Fix uninitialized cache when pthreads are used
Fixes for pthread thread local storage.
[mmx] Fix mask creation bugs
Update README to mention the pixman mailing list
Some minor updates to README
Add pixman_image_get_format() accessor
Remove alphamap from the GTK+ part of tests/Makefile.am
Rename fast_composite_src_8888_x888 to fast_composite_src_memcpy()
Add pixman_region{,32}_intersect_rect()
Add an over_8888_8888_8888 sse2 fast path.
Don't consider indexed formats opaque.
sse2: Add sse2_composite_over_reverse_n_8888
Add support for 8bpp to pixman_fill_sse2()
Don't use __thread on MinGW.
Add macros for thread local storage on MinGW 32
test/gtk-utils: Set the size of the window to the size of the image
Eliminate mask_bits from all the scanline fetchers.
When storing a g1 pixel, store the lowest bit, rather than comparing with
Make separate gray scanline storers.
Fix conical gradients to match QConicalGradient from Qt
Store the conical angle in floating point radians, not fixed point degree
Minor tweaks to README
Make the combiner macros less likely to cause name collisions.
Fix memory leak in the pthreads thread local storage code
Hide the global implementation variable behind a force_inline function.
Cache the implementation along with the fast paths.
Split the fast path caching into its own force_inline function
test: Make sure the palettes for indexed format roundtrip properly
When converting indexed formats to 64 bits, don't correct for channel
wid
Make the repeat mode explicit in the FAST_NEAREST macro.
In the FAST_NEAREST macro call the function 8888_8888 and not x888_x888
fast-path: Some formatting fixes
Check for read accessors before taking the bilinear fast path
[fast] Add fast_composite_src_x888_8888()
[sse2] Add sse2_composite_src_x888_8888()
[sse2] Add sse2_composite_in_n_8()
[sse2] Add sse2_composite_add_n_8()
bits: Fix potential divide-by-zero in projective code
Add x14r6g6b6 format to blitters-test
If we bail out of do_composite, make sure to undo any workarounds.
CODING_STYLE: Delete the stuff about trailing spaces
Fix Altivec/OpenBSD patch
Extend scaling-crash-test in various ways
Replace compute_src_extent_flags() with analyze_extents()
Eliminate recursion from alpha map code
Eliminate get_pixel_32() and get_pixel_64() from bits_image.
