    Basing my answer on the knowledge (which there is not a lot of on povray in my
mind as we speak) that povray tesselates everything into triangles before render
time, rendering shouldn't be a problem.  All that would be needed is a nurbs
tesselater into the pipeline, i haven't looked at the povray code but wouldn't this
be how the bicubic patches are handled or is it directly rendering the bicubic
surface (not tesselating it).
