I just kind of remembered that if we're doing (xy+x)/256 and x is a destination channel and y is 255-sa, then you can get the +x for free by multiplying by 256-sa instead. (d * (255-sa) + d) (d * (255-sa + 1)) (d * (256-sa) ) Duh. This is a trick we play in a lot of legacy code and I've just now realized it's exactly equivalent to the trick I want to play here... sigh. Folding this math in kind of makes mul/mad_unorm8 moot.
