I was wondering why splines, within POV, are not all interchangeable and
applicable everywhere. Are not all splines the same basic thing? Lemme
see if I recall the different types in existance. There are Linear,
Quadratic, Cubic, Bezier, Catmull-Rom, B, NURB, Hermite, etc., etc.
Could all these different types be added to POV in such a way that they
could be used everywhere? For example, that I could use a bezier spline
in a sphere_sweep, or a catmull-rom spline in a prism? And the spline
keyword in the SuperPatch, couldn't it be made to accept all splines?

[Note: POV designates official, and superpatch versions]
