 Concrete physical shape - a GL drawable. Physical shapes are the     
 objects the user can actually see, select, move in the viewer. It is 
 a placement of the associated local frame TGLLogicaShape into the    
 world frame. The draw process is:                                    
                                                                      
 Load attributes - material colors etc                                
 Load translation matrix - placement                                  
 Load gl name (for selection)                                         
 Call our associated logical shape Draw() to draw placed shape        
                                                                      
 The physical shape supports translation, scaling and rotation,       
 selection, color changes, and permitted modification flags etc.      
 A physical shape cannot modify or be bound to another (or no)        
 logical shape - hence const & handle. It can perform mutable         
 reference counting on the logical to enable purging.                 
                                                                      
 See base/src/TVirtualViewer3D for description of common external 3D  
 viewer architecture and how external viewer clients use it.          

 Construct a physical shape using arguments:
    ID             - unique drawable id.
    logicalShape   - bound logical shape
    transform      - transform for placement of logical drawing
    invertedWind   - use inverted face polygon winding?
    rgba           - basic four component (RGBA) diffuse color

 Construct a physical shape using arguments:
    ID             - unique drawable id.
    logicalShape   - bound logical shape
    transform      - 16 Double_t component transform for placement of logical drawing
    invertedWind   - use inverted face polygon winding?
    rgba           - basic four component (RGBA) diffuse color

 Destroy the physical shape

 Update our internal bounding box (in global frame)

 Initialise the colors, using basic RGBA diffuse material color supplied

 Set full color attributes - see OpenGL material documentation
 for full description

 0...3  - diffuse
 4...7  - ambient
 8...11 - specular
 12..15 - emission
 16     - shininess

 Draw physical shape, using LOD flags, potential from display list cache

 Draw physical shape, using LOD flags - can be captured into display list cache

 Load gl name (for selection)
 Load translation matrix - placement
 Call associated fLogicalShape Draw() method

 Return draw flags for shape, suitible for use under projection defined by 'camera',
 taking account of which local axes of the shape support LOD adjustment, and the
 global 'sceneFlags' passed.

 sceneFlags.Style() - copied to shape draw style
 sceneFlags.LOD() - factored into projection LOD

 Returned LOD() component is UInt 0 (kLODPixel - lowest quality) to
 100 (kLODHigh - highest quality) or special case kLODUnsupported if shape
 does not support LOD at all

 Request creation of context menu on shape, attached to 'menu' at screen position
 'x' 'y'
