Oh yeah, one thing I noticed is that the SSSE3 version of RV40 chroma
MC is missing, probably b/c of the different rounding. Is there any
reason it's implemented this way and (given no speed loss for
H264/VC1), is it OK if I change the SSSE3 function prototype to fit
RV40 as well, like the MMX function prototype? Should make RV40
decoding significantly faster.
