t-pivot Animation #2

I need to create an easy way to animate the t 'pivot' moving along its control polygon.

The fix I implemented was to define a unit vector in the direction from tracker to p2 as well as a span (the magnitude of the vector from the tracker center to p2 center). To animate the tracker moving, shift in the direction of the unit vector by a scale factor [-span, span]... one major issue is it is still possible for a user to shift beyond the bounds of the control points, but it works for my application, so I'll leave it for now.
