ScaleTransition and RotationTransition have duplicate code for the the alignment and filterQuality logic.
A more generic animation to Matrix Transition could both factor the duplicate code, and provide an easy way to make more Matrix based animations.

This is a proposal to make a new generic MatrixTransition class, with the common code, and make ScaleTransition and RotationTransition special cases of it.
