bool bGizmoBeingDragged
Used to make it easy to tell whether the gizmo was moved by the user or by undo/redo or some other change that we shouldn't respond to. Basing our movement undo/redo on the gizmo turns out to be quite a pain, though may someday be easier if the transform proxy is able to manage arbitrary objects.
