Previously our region code was just a simple y,x sorted list of
non-intersecting rectangles. This can cause us to have simple regions
represented in a complex unoptimizable way.
Switching to pixman regions gives us a canonical region implementation.
There are some cases when this can cause performance regressions.
For example, with the old region code we end up with this region:
http://people.mozilla.org/~jmuizelaar/region-pre.html
which is represented like this:
http://people.mozilla.org/~jmuizelaar/region-post.html
with the new code.
We call SimplifyOutward(4) on this. With old regions we can't simplify it so we
end up taking the bounds and get 1 rect. With the new regions we have only 3
rects to start and so we do nothing. The difference between 3 rects and 1 rect
cause D2D to do a PushLayer() instead of a ClipRect() and that seems to be the
causes for the regression.

What LIBXUL_LIBRARY does is:
- Imply FORCE_STATIC_LIB
- Build with -DIMPL_LIBXUL
- Build with -DMOZILLA_INTERNAL_API
Those intermediate libs that end up in gkmedias and have LIBXUL_LIBRARY defined
in their moz.build are all third party code (or handled like third party code).
Besides FORCE_STATIC_LIB, none of the side effects of LIBXUL_LIBRARY should be
needed.

This does a 2x2 ordered dither in the same way that Skia does.
One of the things I'm currently unhappy with is that it duplicates
the gradient walker code for 16 bits. We could turn it into a large
macro that does the appropriate things for 16 bit and 32 bit
versions, but that's not particularly appealing.

This takes the bilinear interpolation code from Skia. It
uses 4 bits of precision instead of 8. This lets it interpolate
two components at a time because the results fit in 16 bits.
The lower precision code is only used in the fallback code
and not in any of the specialized code for NEON. This means
pixman gives different results depending on the cpu which isn't
great. However, this was easiest and the NEON code doesn't
gain as much from using lower precision.
Skia actually uses even lower interpolation when working with
565 but that's harder to plug in right now, and this gives
a reasonable improvement.

Tor Lillqvist (1):
Support __thread on MINGW 4.5
Non-libxul builds include pixman.h directly instead of having it included
by pixman-private.h which defines PIXMAN_USE_INTERNAL_API. So we ensure
PIXMAN_USE_INTERNAL_API is defined before including pixman.h
The disassembler was producing:
strh r4, [r0, #2]
instead of
strh r4, [r0], #2
which was causing the alignment and index to go all wrong causing crashes.
