Uhh, are you sure we really want to make that change now? It will
increase the amount of data and possibly slow things down. Currently,
we can hack away all the cases that don't work.

BTW: rotation, clipping etc. in OpenGL can be achieved by putting
in Vobs that affect the OpenGL state (see putnoc in the demos;
especially try in the fillet demo rotating the one view to an oblique
angle)
