GUIEventHandler provides a basic interface for any class which wants to handle a GUI Events.
The GUIEvent is supplied by a GUIEventAdapter. Feedback resulting from the handle method is supplied by a GUIActionAdapter, which allows the GUIEventHandler to ask the GUI to take some action in response to an incoming event.
For example, consider a Trackball Viewer class which takes mouse events and manipulates a scene camera in response. The Trackball Viewer is a GUIEventHandler, and receives the events via the handle method. If the user 'throws' the model, the Trackball Viewer class can detect this via the incoming events, and request that the GUI set up a timer callback to continually redraw the view. This request is made via the GUIActionAdapter class.
Convenience method that only passes on to the handle(,,,) method events that either haven't been handled yet, or have been handled but haven't be set to be ignored by the IgnoreHandledEventsMask. Note, this method is an inline method, and not appropriate for users to override, override the handle(,,,) method instead.
