Log message:
Merge r1.36 of fbcompose.c from xserver CVS:
Special case projective transforms so we can avoid doing the expensive
64-bit math. Unroll the bilinear interpolation loops for an extra
boost.
I tested this with the up/downscaling cairo-benchmarks with Xvfb and
saw a 12% +/- 4% decrease in time taken to run them.
