Remarks
IScreenDisplay::Invalidate fires this event to notify all clients a display has been invalidated. The display, the area invalidated, the erase setting, and the cacheID are all returned to clients listening to this event.
The Map object is one client that listens for this event and it may in turn fire the IActiveViewEvenets::ViewRefreshed event.
