Event to use if you want to dynamically draw things as the mouse/digitizer moves.
Every time the mouse moves, DynamicDraw will be called once per viewport. The
calls to DynamicDraw happen AFTER the call to MouseMove.
If you are drawing anything that takes a long time, periodically call
InterruptMouseMove() to see if you should stop.
