class TGLEventHandler: public TGEventHandler


 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:
 OpenGL.EventHandler.ViewerCentricControls:  1
 OpenGL.EventHandler.ArrowKeyFactor:        -1.0
 OpenGL.EventHandler.MouseDragFactor:       -1.0
 OpenGL.EventHandler.MouseWheelFactor:      -1.0
