[cairo] How do I use an XRender Picture as a Cairo surface?

Could we get my patches to pixman (which make pixman implement GOOD/BEST
directly) pushed? This would allow Cairo to not have to fall back to the
image backend for these filters. Good is really not much slower than
bilinear at scales where the bilinear result is acceptable, so it appears
the overhead of the image backend is considerable.
I have a separate patch to allow cairo to use pixman for GOOD/BEST, but it
requires knowledge of what version of X11 supports it.
This would also allow pixman to be enhanced to do 2-pass filtering, which
is sorely needed and Cairo is only about 15 years behind on this...
