MaterialRectCenterArcTween class

A Tween that interpolates a Rect by moving it along a circular arc from begin's to end's while interpolating the rectangle's width and height.

The arc that defines that center of the interpolated rectangle as it morphs from begin to end is a MaterialPointArcTween.
