A long time ago someone mentioned that they had written a preliminary
patch for NURBS.  I think it was Nathan but the messages I have don't
seem to go back far enough.

Anyway, the person offered to share it with anyone interested.  If I can
find the time, I plan on writing a patch to do direct rendering of
bicubic patches, and it seems it should be possible to include NURBS.  I
could use any help I could get, so it would be great if whoever has that
code could forward it to me.  :)

I hear that the direct approach causes rendering artifacts, but I'd like
to try it just the same.
