[Fluxus] nurbs explode FAIL

oh, yes. sorry, i forgot about that. there are some extra control points 
for nurbs surfaces. it's a bit confusing, so i was suggesting some time 
ago to make smaller surfaces, but stick to the pdata size the user 
requires. for example for nurbs planes you get +1 rows and columns.

i think you can solve it by making the list (+ dim 3) size:
(define vals (build-list (+ dims 3) (lambda (n) (rndf))))
