bd9934551f Move __force_align_arg_pointer workaround before composite32() 
Since otherwise the workaround won't take effect when you call
pixman_image_composite32() directly.

3db76b9004 Restructure the flags computation in compute_image_info(). 
Restructure the code to use switches instead of ifs. This saves a few
comparisons and make the code slightly easier to follow. Also add some
comments.

16ef3ab230 Add a1-trap-test 
When a trapezoid sample point is exactly on a polygon edge, the rule
is that it is considered inside the trapezoid if the edge is a top or
left edge, but outside for bottom and right edges.

This program tests that for a1 trapezoids.

94f585916a 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().

61f4ed9c7a Compile by USE_SSE2 only without USE_MMX 
Although we added MMX emulation for Microsoft Visual C++ compiler for x64,
USE_SSE2 still requires USE_MMX.  So we remove dependency of USE_MMX
for Windows x64.

6b2da683de Move NULL check out of get_image_info()

do it for destinations and sources.

1dd8744f40 Add a fast path for non-repeating sources in walk_region_internal(). 
In the common case where there is no repeating, the loop in
walk_region_internal() reduces to just walking of the boxes involved
and calling the composite function.

362a9f564a Move more things out of the inner loop in do_composite().

- the check for whether the involved images cover the composite

f831552bce Optimize for the common case wrt. the workaround. 
In the common case no images need the workaround, so we check for that
first, and only if an image does need a workaround do we check which
one of the images actually need it.

fa4df6225d Eliminate all the composite methods. 
They are no longer necessary because we will just walk the fast path
tables, and the general composite path is treated as another fast
path.

This unfortunately means that sse2_composite() can no longer be
responsible for realigning the stack to 16 bytes, so we have to move
that to pixman_image_composite().

488480301c Don't call _pixman_implementation_composite() anymore. 
Instead just call _pixman_run_fast_path(). Since we view

87430cfc35 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.
