IMO adding tesselation of any object would be nice. There is a patch 
for it, but a troublesome one as I understand.

Speed isn't the main thing for me in this, altough it can be usefull 
for animations.

The interesting things with tesselation are what other things one can 
do with a mesh. Think of export to other programms. Manipulation of the 
mesh with POV-Ray, regardless of wether it is done by POV-Ray directly 
or through include files. Think of subsurface division, surface 
displacement, boning, uvmapping etc.

For these I think we'd need a bit extended mesh format, one that also 
accepts (non-flat) polygons.

More important, we'd need to get access to the arrays a mesh2 consists 
of so mesh can be manipulated through SDL.
