A DCS's center of rotation is the origin (0,0,0) of the model, i.e.
the origin of the portion of the scene graph beneath the DCS. If
you wish to change the center of rotation either build your own
matrix that does T*R*-T or add another DCS below the rotation with
translation of T and have your rotational DCS include a translation
of -T, i.e.

Geode * ... * DCS(T) * DCS(R*-T) * .... * ChanView
