Tesselation...some objects would render faster if tesselated, and you 
could use the tesselated version as a preview. Also, a low-res 
tesselated version of an object might be useful as a bounding shape for 
some objects.

I think the best way to do this would be a "tesselation {}" keyword for 
objects to specify options and that tesselation should be used. On 
objects which can't be tesselated(julia fractals, CSG, etc), a box, 
sphere, or other approximation could be used.
Infinite objects are more of a problem...a plane could be two triangles 
with the vertices at the largest distance POV can handle, but things 
like poly would have to generate a warning.


Fancy API's? Not needed, and left out for good reasons...
