I presume one of the advantages of RGB for software is that it's
additive: if you have two images that you want to mix, and you have
the pixels as R,G,B color components, mixing becomes trivial (just
average the components).  Many shading algorithms also use this
additive property extensively.  I don't think this is as easy for YUV.
