Well, POV 3.5 uses methods that compute the normal, insideness of a 
point, all intersections with a ray, UV coordinates, copy/destroy the 
shape, invert the shape, and the various transformations (translate, 
rotate, scale, and transform). There are also functions for creation and 
computing bounding boxes, and sometimes others. Make a 3.5 patch and it 
shouldn't be too hard to adapt for 4.0, but it is likely you would have 
to rewrite most of the code, and there could be very different 
requirements.

Going to give any hints as to what you are planning? ;-)
