anything involving yuv has to one way or another deal with multiple yuv
variants. for yuv2yuv there will be a simple same yuv type case (what we
have now) and a case for differing yuv type.
but for rgb<->yuv there are coefficients that can be changed and so only
one case in the code has to exits, handling multiple yuv types should be
