	tag: pixman-0.19.2

	Andrea Canciani (2):
	      support single-stop gradients
	      test: verify that gradients do not crash pixman
	Brad Smith (1):

	      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

	      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
