Now that we have the full image flags available, the SSE2 and MMX
iterators can simply check against SAMPLES_COVER_CLIP_NEAREST (which
is computed in pixman_image_composite32()) instead of comparing all
the x/y/width/height parameters.

From: Søren Sandmann Pedersen s...@redhat.com
When pixman_image_composite32() is called some flags are computed that
indicate various things about the composite operation that can't be
deduced from the image flags themselves. These additional flags are
not currently available to iterators. All

I don't believe the changes were ever reverted.

When a destination image I has an alpha map A, the following rules apply:
- If I has an alpha channel itself, the content of that channel is
undefined
- If A has RGB channels, the content of those channels is
undefined.

When adding glyphs to the mask, bypass most of the overhead of
pixman_image_composite32() by:
- Only looking up the composite function when the glyph changes either
format or flags.
- Just intersecting the glyph rectangle with the destination

This way it can be used in other tests.

This new API allows entire glyph strings to be composited in one go
which reduces overhead compared to multiple calls to
pixman_image_composite32().

This commit adds some new inline functions to maintain a doubly linked
list.
The way to use them is to embed a pixman_link_t into the structures
that should be linked, and use a pixman_list_t as the head of the
list.
The new functions are

Maybe the difference is that you are using -O0 where Ryan is using

It's actually added in the two optimizations later in the series. I used
to have them in the API patch too, but they must have gotten lost in the
rebases. I'll add them there too.
Thanks,
