Bool_t MouseEnter(TGLOvlSelectRecord& selRec)
 Mouse has enetered this element.
 Return TRUE if you want additional events.
Bool_t MouseStillInside(TGLOvlSelectRecord& selRec)
 A new overlay hit is about to be processed.
 By returning FALSE one can force mouse-leave (MouseLeave will be
 called shortly).
 If you return TRUE, Handle will be called soon.
 Use this if your overlay object has some inactive parts,
 see TGLManipSet.
Bool_t Handle(TGLRnrCtx& rnrCtx, TGLOvlSelectRecord& selRec, Event_t* event)
 Handle overlay event.
 Return TRUE if event was handled.
void MouseLeave()
 Mouse has left the element.
TGLOverlayElement& operator=(const TGLOverlayElement& )
virtual ~TGLOverlayElement()

void Render(TGLRnrCtx& rnrCtx)
