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 avoids a crash by writing to d3d9surface member on surfaces
that are not win32

win32: Use a font_face hash table to provide unique font faces
win32-font: Improve static data reset function
Bug 717178. Part 2: Import changesets eb29a25d, 6e3e3291 and 101fab7c from upstream.
======
From 101fab7cd8a90f7cf3d8113c792b3f8c2a9afb7d Mon Sep 17 00:00:00 2001
The hashtable is guaranteed to only contain font faces which are
currently referenced, hence there is no need to remove any font face
when it is reset (just like for toy-font).
This makes the function simpler and fixes the assertion
Assertion failed: predicate != NULL, file cairo-hash.c, line 373
hit by multiple tests (the first one being "clear").
See https://bugs.freedesktop.org/show_bug.cgi?id=38049

Similar to the freetype and toy font backends, use a hash table
to map logfont,hfont to font faces.
This fixes the multiple embedding of the same font in PDF.

the compiler is smart enough to turn it into something fast.

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.

Skia uses a value of 0.5, however using such a high value causes some reftest failures.
Switch to 0.3 because we can do that without changing the reftests too much. We
can still use a higher value if we need to later. This should give us sqrt(3)
reduction in the number of segments.

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.
It seems like we sometimes end up using EXTEND_NONE unintentionally, this is
likely caused by different rounding between cairo and pixman. Pixman already
does a similar reduction to EXTEND_NONE so there's not point in duplicating it
here.
