Comment (by Balling):

 >Well, the regression is after this commit, so it clearly affects rgb2yuv
 and in wrong way too.


 It disabled more accurate SIMD, so that broke rgb2yuv. Here the issue is
 in rgb2yuv, not yuv2rgb. I remember that when that commit was done someone
 cerified that it is closer to what H.273 wants.
