void BeginScene()

Bool_t RebuildScene()
If we accepted all offered physicals into the scene no point in
rebuilding it
Int_t AddObject(const TBuffer3D & buffer, Bool_t * addChildren)
Add an object to the viewer, using internal physical IDs
Int_t AddObject(UInt_t physicalID, const TBuffer3D & buffer, Bool_t * addChildren)
Add an object to the viewer, using an external physical ID.
Bool_t OpenComposite(const TBuffer3D & buffer, Bool_t * addChildren)
void CloseComposite()
If we have a partially complete composite build it now
void AddCompositeOp(UInt_t operation)
Int_t ValidateObjectBuffer(const TBuffer3D & buffer, Bool_t logical) const
kCore: Should always be filled
TGLLogicalShape* CreateNewLogical(const TBuffer3D & buffer) const
Buffer should now be correctly filled
TGLPhysicalShape* CreateNewPhysical(UInt_t ID,
const TBuffer3D & buffer,
const TGLLogicalShape & logical) const
Extract indexed color from buffer
TODO: Still required? Better use proper color triplet in buffer?
RootCsg::BaseMesh* BuildComposite()
void InitGL
void SetupCameras(const TGLBoundingBox & box)
void SetupLights()
Setup lights
void DoDraw()
Draw out the the current viewer/scene
void PreDraw()
GL work which must be done before each draw of scene
void PostDraw()
GL work which must be done after each draw of scene
void MakeCurrent() const
void SwapBuffers() const
void RequestDraw(UInt_t LOD)
Bool_t DoSelect(const TGLRect & rect)
Select lock should already been taken in other thread in
TGLViewer::DoSelect()
void RequestSelect(UInt_t x, UInt_t y)
Take select lock on scene immediately we enter here - it is released
in the other (drawing) thread - see TGLViewer::Select()
Removed when gVirtualGL removed

void SelectionChanged()
Int_t DistancetoPrimitive(Int_t /*px*/, Int_t /*py*/)
Can't track the indvidual objects in rollover. Just set the viewer as the
selected object, and return 0 (object identified) so we receive ExecuteEvent calls
