My use for a spline is to make keyframes for a walk cycle. It's hard enough
to figure out how to figure out the points _within my range_ to look right.
I find it mentally aggravating to have to 'add' two extra points on either
side to figure out how to make it smooth and well-behaved. If I were making
a solitary camera path, yes I might use a cubic spline, but not when I have
8-16 splines to manage at once!
