Use postfix decrement, not prefix, in region-test.c

Eliminate empty rectangles in pixman_region_init_rects().

Otherwise they show up in the validated regions.

Add an initialization with an empty rectangle to region-test.c

This should produce a valid region without empty rectangles in
it. Currently it doesn't.

Expand comment in miClipPictureSrc() to explain why a client clip is required.

Fix forgotten use BITMAP_BIT_ORDER to be ifndef WORDS_BIG_ENDIAN

Return TRUE for the two new formats in pixman_format_supported_source().

Inlucde pixman-private.h in pixman-region.c

Delete some duplicated macros.

Rename OptimizedOperatorInfo to optimized_operator_info_t

Add accessor functions for PIXMAN_x2r10g10b10 and PIXMAN_a2r10g10b10

Avoid overrunning scanlines in NEON blitters.

Really fix ARM build.

Commit 9d3f71d726c8b959b64c3e6b43ca4d3ccb320c32 broke the build
on ARM architectures by just removing custom include files and
not providing "pixman-private.h" as a replacement.

Fix ARM build.

Commit 6e20c2574354d1cb071a1201ff166cb5e92c00d2 broke the build on ARM
architectures by not updating the use of fbComposeGetSolid()
correctly.

Change checks for srca == 0 to src == 0

It is not generally correct to bail out just because the source alpha
is 0. The color channels still mig not be and in that case the correct
result is:

       s + (1 - srca) * d = s + d

which is not generally 0.

Make arm compositing functions static

Delete ARM header files

Use -mcpu instead of -march for ARM SIMD runtime autodetection

Option -mcpu has higher priority than -march with the current versions
of gcc and that's why it is better to use. There is no particular
reason why 'arm1136j-s' is used in this patch, it could be any armv6
compatible core.

Add test cases to oob-test using PIXMAN_{a,x}2b10g10r10

Post-release version bump

Pre-release version bump

Delete scanFetchProc type. Use fetch_scanline_t instead.

fetch_scanline_t now takes a pixman_image_t argument instead of an
bits_image_t, so there is also a bunch of updates in pixman-access.c

Constify the mask argument to scanline fetchers.

Add a mask and mask_bits argument to the raw scanline fetchers.

Rename fetchProc32 to fetch_scanline_t and fetch_pixels_32_t to fetch_pixels_t

Get rid of the 64 bit fetcher types.

It's simpler to just declare everything as 32 bit fetchers and do the
conversion in the few functions that actually need to know the size of
the pixel type.

Consolidate the three scanline store types into one.

The 64 bit storers do their own type conversion.

Get rid of remaining scanFetchProc casts

Get rid of scanFetchProc casts in pixman-radial-gradient.c

Get rid of scanFetchProc casts in pixman-conical-gradient.c

Get rid of casts to scanFetchProc in pixman-bits-image.c

Instead just declare the functions with the required type and do any
type conversions in the function itself.

Fix bug where 64 bit pixel were fetched as 32 bit ones.

Delete FbIntMult and FbIntDiv macros, and move FbIntAdd to pixman-combine.h

Add a table to oob-test so that it can test more than one setup.

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.

Fix typo in oob-test.c

Add test case for out-of-bounds memory access.

Fix comment in pixman-utils to have the right sense.

Subtract x_off/y_off before conversion to integer.

They are fixed-point values, not integers.

Bug 22437, reported by Michel Dänzer.

Add convolution-test.c program

Delete leftover use of PIXMAN_OP_FLASH_SUBTRACT

Remove support for component alpha with HSL blend modes.

It isn't clear that component alpha makes sense with HSL blend modes.

Remove FLASH_SUBTRACT blend mode.

We may resurrect it later, but leave it out for now, as the closest
thing we have to a spec:

http://www.kaourantin.net/2005/09/some-word-on-blend-modes-in-flash.html

claims that alpha values should be subtracted, whereas real-world flash
files indicate that they shouldn't.

Fix BlendColorBurn

It should return 0 when sa == 0

Add screen-test.c test program

Make the composite test window bigger by default.

Also rearrange the squares to better match typical aspect ratios.

Use floating point in SetLum

fix Multiply component-alpha version

fix comment

fix component-alpha versions for seperable blend modes

rename operator SUBTRACT to FLASH_SUBTRACT

Also document it and move it out of the PDF blend modes to make clear
that it is not in any way related to PDF.

rework blend-mode documentation to match current code better

typo fix: Seperable => Separable

remove semicolon at end of macro

remove a leftover debugging statement

That was an assertion check by infinite loop

invent a Subtract operator for component alpha

This seems to make sense, and as I can't test it against Adobe's Flash
player as that one can't do component alpha, this one looks best.

add non-seperable versions for component alpha
