// Use of this event for highlighting repaint

// in the Camera class:
// c->get_scene_context()->register_data();
//
// RepaintRect may be initiated at the request 
// of a leaf that needed redraw. In such cases
// RepaintRect will store the troublemaker's 
// address and some data associated with the 
// poor bastard. Upon processing, the requestor 
// may retrieve this data and figure out the 
// redrawing actions it should take.
//
// Please note that this event CANNOT have 
// data when sent into the timed queue via 
// GraphWindow::enqueue_event()
// because it was intended to pass local data
// (from the stack) and thus that data will
// become invalid when the event reaches
// processing.
