e5a5c78045 Use a big triangle instead of 2 to cover full screen. 
This allows to rasterize a single primitive instead of two, and avoid
trashing the cache between the 2 triangles drawing.

e571afc43b Speed up SSAO again 
Use log2(xy) = log2(x) + log2(y), and approximate log2(alpha) =
log2(previous alpha) + .5.
Log2 is indeed a costly instruction.
