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.
