I am working on a postscript renderer class, derived from the OpenGL
Renderer class.  As soon as I have done more work on it I will post to
this mailing list.  (I was unable to find such a class on the internet, so
if someone knows of something please let me know.)  It is based on some
code (I think was written by Mark Kilgard) that uses OpenGL Feedback mode
to render the geometry and then produces an Encapsulated Postscript (EPS)
file.  This preserves the high-resolution rendering.
