* globalToLocal was just broken when there was a rotation and a translation at the same time. This fixes that and adds a test. * update graphic used by spinning_mixed since the old one went 404. * simplify some of the code in the demo. * fix MatrixUtils.transformPoint to be consistent with how we transform points elsewhere. * stop transforming points elsewhere, just use MatrixUtils.transformPoint. * make the Widget binding handle not having a root element. * make the spinning_mixed demo update its widget tree.
