Now, that would be an _excellent_ idea.  Maybe another list member
will volunteer to do it or contact GNOME and KDE people and have this
done, just to see...

I've dug very deeply into X for many years, so the results will make
sense to me, although they may surprise me.  :)

Actually, I'm betting it's mostly PutImage and CopyArea.  X lacks
primitives to render many of the things people want to see in these
GUIs.
