Since splines allows to adjust both control points and time values, it's
often possible to tweak a spline to be somewhat constant in speed.

However, when people walk they don't keep constant speed. Every time one
starts or stops walking or when turning in a curve the speed of the walk
changes. When one goes from walk to run or things like that the speed also
changes.

Yes, that's the idea. Not implemented yet though, but I'm working on it.
