Base-class and default implementation of event-handler for TGLViewer.
This allows for complete disentanglement of GL-viewer from GUI event handling. Further, alternative event-handlers can easily be designed and set at run-time.
The signals about object being selected or hovered above are emitted via the TGLViewer itself.
The following rootrc settings influence the behaviour:
