Fix bug 16310 in the SSE2 fast path in function
fbCompositeSolidMask_nx8888x0565Csse2
commit eb53d111bd8651cd00c1b728b09e8be09b8482f7
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.

- Delete pixman_region_empty()
- Make pixman_region_validate() static and don't export it.

commit 02268903e4311709744c11e495f9b17f171ec5e9
pixman-sse.c: silence pointer-cast compiler warnings.
Cast pointers to words of the same size, not 32-bits.
commit eb2d95de98683a387153f010077ad9c3c3b1b01d
Fix implicit declaration of function 'free'.
Otherwise pointer will be truncated on 64bit arch and
your programs will crash.
commit 29d144712e558aaeb49f4384028dd669d76a410b
Fix memory leak by freeing boxes{16,32}.
After calling pixman_region_init_rects() or
pixman_region32_init_rects(), boxes{16,32} were not freed before
returning. Fixes bug 16312.
commit 5d32519316b40b35113c6df9e15d955a16709ba2
Use pixman_malloc_ab instead of plain malloc for the
fbStore64_generic scratch buffer.
commit b1c70c4e6435d7f15751111828c381feb1d139cf
Move PIXMAN_FORMAT_16BPC to pixman-private.h
commit 7fa966df0ee781fa486715710f389b148c11d36e
Decide based on the image formats whether we need wide compositing.
commit 7cb735c9c0fa55ae1f4d8d13da9f33e3da2ae8fe
Take the source format into account in pixman_expand.
Extract the original bits of the source image for each
component and then replicate up to 16 bits to fill the wide
components. Make sure to hard-code the alpha value to 1 if
the source format didn't have alpha.
commit c0d98e96605c6d03f4b02f337f2f5827165bb092
Make expansion and contraction loops clearer.
commit fc0b28bf6af81428b7ac045614eea97fbf9c4a70
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.
commit 42a3a2d6fc8d3e521c6914ff8fb89f1fbc673e28
Add wide fetch/store functions.
Use the narrow ones and expand/contract where necessary. Still
need wide paths for fancy pictures, but this gets the
basic stuff working.
commit 7591d3f1d7e0884f9362018edf720724095cf380
Add expand and contract functions to convert between ARGB8
and ARGB16. The expansion function isn't quite correct,
but gives reasonable results.

Skip the SSE2 configure test if we already know we don't have SSE,
because Sun Studio gets the result of the SSE2 test wrong.

Also (this is noted in the Makefile):
The configure script is written to fail if it detects gcc<4.0
for lack of -fvisibility=hidden. In keeping with the pkgsrc
tradition of portability, we'll opt to use libtool to export
the desired symbols, hiding the rest.
I have verified the list of visible symbols is unchanged from
the "factory" build.

Bump rev.
to me than the release. Bump rev.
Changes include:
Guard MMX get_fast_path() with pixman_have_mmx()
Use -fvisibility=hidden by default.
Add a PIXMAN_EXPORT macro that expands to the appropriate GCC magic.
Various formatting fixes.
Make the tables static; remove unused flag
Set maskRepeat to FALSE when the function is NEED_SOLID_MASK
Conditionalize MMX code with USE_MMX
Don't skip fbFetch/fbStore when PIXMAN_FB_ACCESSORS is enabled.
pixman_composite_rect_general_accessors skips the fetch / store steps by
setting store to NULL when the op is ADD or OVER and the dest format is

Presently, nothing depends on this library, but probably will soon.
Also, those building their own Xorg servers will need this.
