If you're looking for U/V mapping (where the image follows the bezier patch as
it's stretched), go to
http://www.public.usit.net/rsuzuki/e/povray/iso/index.html
This unofficial version of POV has a limited ability to do U/V mapping of
bezier patches. I know about it 'cause I programmed it... I also know that
it's a bit
buggy and quite limited, but it does work.
