There was a "triangle scanner" include file a while ago that did this, I 
think it was written for MegaPOV. The method it used didn't work very 
well, it was mainly only useful for a cheap preview.
It would theoretically be possible to duplicate the tessellation patch 
in POV-Script using trace(). It'd be a lot slower, and wouldn't have any 
advantages over the patch.
