  I know, but I think that that extra stuff doesn't need very much
modifications to the povray core code.
  However, I think that an OpenGL preview mode would require a lot of changes
in the povray core.

  OpenGL is not available in this SparcStation 5 either...

  You are right of course. If someone can do it easyly, then that's great.
  The only problem I see is that you can't tesselate every primitive in
povray (mainly the infinite ones, like planes and polys).

  Btw: Are there _any_ renderer that can do _real_ non-uniform transformations
to objects?
  Changing the location of triangle vertices is not real non-uniform
transformation.
