Bug 717178. Part 2: Import changesets eb29a25d, 6e3e3291 and 101fab7c from upstream.

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").

Subject: win32: Use a font_face hash table to provide unique font faces
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 new version of the code is more obviously correct. Hopefully
the compiler is smart enough to turn it into something fast.

Cairo is a 3rd party project and we decided in bug that silencing the
warnings was easier than patching.

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 a trick from skia to go faster. For now, it's only
used on non-NEON devices.

This will allows us to scale and repeat in a single pass instead
of doing it in two.

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.
