* The `reboundTraj` (trajectory) is meant to start with the vector that the object over-shot the constraint.

I got my before / after objects switched, resulting in some "opposite" results.
  - meaning, the delta should be (after - before)
  - though (admittedly) this really depends on how the overall vector is treated and how much it needs to be rotated and in which direction. Alas.  This restores it to my original intent.
