This patch fixes RGBA -> YV12 blending for the most part, see trac
ticket [1]. What's still missing is blending of chroma on edge pixels if
they don't line up with chroma blocks. It's still clearly an improvement

A cleaner solution might be to blend onto a temporary I444 picture and
downsample to I420 afterwards.
