The problem there is not so much Motif, it's openGL.  I don't know why
gtk went with cairo instead of openGL.  For awhile there was gtkglext,
and I still have support for it in Snd, but I believe it has died.  I'll look
again at cairo (geez, I hate that name -- I can't rid myself of the
suspicion that I'm dealing with crypto-proselytizers), and see if it
has 3D graphics support.  Or maybe there's some other way in gtk?
