 Abstract base class for viewer manipulators, which allow direct in   
 viewer manipulation of a (TGlPhysicalShape) object - currently       
 translation, scaling and rotation along/round objects local axes.    
 See derived classes for these implementations.                       
                                                                      
 This class provides binding to the zero or one manipulated physical, 
 hit testing (selection) for manipulator sub component (widget), and  
 some common mouse action handling/tracking.

TGLManip& operator=(const TGLManip& gm)

assignement operator

~TGLManip()

 Destroy manipulator object

Bool_t Select(const TGLCamera & camera, const TGLRect & rect, const TGLBoundingBox & sceneBox)

 Select active widget (axis component) of the widget

Bool_t HandleButton(const Event_t & event, const TGLCamera & /*camera*/)

 Handle a mouse button event - return kTRUE if processed, kFALSE otherwise

Bool_t HandleMotion(const Event_t & event, const TGLCamera & camera, const TGLBoundingBox & sceneBox)

 Handle a mouse button event - return kTRUE if widget selection change
 kFALSE otherwise

void CalcDrawScale(const TGLBoundingBox & box, const TGLCamera & camera, Double_t & base, TGLVector3 axis[3])

 Calculates base and axis scale factor (in world units) for drawing manipulators with
 reasonable size range in current camera.

void Attach(TGLPhysicalShape * shape)

{ fShape = shape; }

TGLPhysicalShape * GetAttached()

{ return fShape; }

void Draw(const TGLCamera & camera)
