Well, except the bug that causes some control points to be ignored, but you
couldn't reproduce that on your development model, so it was never fixed.

Furthermore the cubic spline function is different from the cubic spline
used in prisms, even if the control points are exactly the same. While that
may not be a bug, it sure is a strange inconsistency.
