That's the best way in my opinion since I'm bit of povray purist. It would be
nice if beziers were included as options in features where they are not
currently available (such as spherical sweeps), since beziers and linear
splines are alot easier to visualize (in my insignifigant opinion for what
little change that is worth). And since beziers require a lot less points than
a linear spline that looks otherwise identical, it seems to make sense.

Any chance of these getting into future POV Ray versions?
