Thanks -- I've checked out GM and done a diff of composite.c. I think
that it has most of what I need at the moment. One thing I still don't
quite get. I had supposed that you'd need different composition algorithms
for different colour models, but I cannot find them, even though I have
found support for CMYK in GM/IM.
