Cool, I'll have to try this!

Saturation belongs in -vop eq, IMHO. Actually the code is pretty much
already there -- just apply the contrast filter to the chroma planes.
But be sure to special case default saturation so that the chroma
planes can pass thru without copying if no saturation adjustment is
desired.
