WCMotionEH : WorldCanvas Motion Event Handler

Synopsis

Designed for derivation, this class is the base class which is communicated to when the it is necessary to refresh the display. The application programmer should derive from this class, add any data fields needed, and override operator () to redraw the screen properly.
