  G4TrajectoryDrawerUtils.cc.

  in G4VModel, which is used by default, is simply to return the global
  description and tag.

- Fixed memory leak in G4PhysicalVolumeMassScene.

13th September 2004  John Allison  (modeling-V06-02-00)

// Calculates the mass of a geometry tree taking into account daughters
// up to the depth specified in the G4PhysicalVolumeModel.  Culling is
// ignored so that all volumes are seen.
//
// The calculation is quite tricky, since it involves subtracting the
// mass of that part of the mother that is occupied by each daughter and
// then adding the mass of the daughter, and so on down the heirarchy.
//
// Usage for a given G4PhysicalVolumeModel* pvModel:
//   G4PhysicalVolumeMassScene massScene;
//   massScene.EstablishSpecials (*pvModel);
//   pvModel->DescribeYourselfTo (massScene);
//   G4double volume = massScene.GetVolume();
//   G4double mass = massScene.GetMass();
//   massScene.Reset();
// See, for example, G4ASCIITreeSceneHandler::EndModeling().
- Added some access functions to G4PhysicalVolumeModel:
    GetTopPhysicalVolume, GetRequestedDepth, SetRequestedDepth.
- Protected GetPhysicalVolumeModel when all volumes "invisible".

12th November 2003  John Allison  (modeling-V05-02-02)

23rd February 2002  John Allison (vis-V04-00-02)
- Removed Begin/EndPrimitives from G4HitsModel and
  G4TrajectoriesModel.  This was causing nested calls to
  Begin/EndPrimitives (and thus to glNewList/EndList in OpenGL stored
  mode), since the trajectories and hits Draw methods themselves have
  Begin/EndPrimitives.

24th August 2001  John Allison  (vis-V03-02-13)
- Intoduced argument for printing in G4VModel::Validate(G4bool warn).

  standing bug!).

  textual or graphical representation of the geometry hierarchy is now
  done in G4xxxTree classes in visua;ization/Tree.

25th July 2001  John Allison  (modeling-V03-02-03)
- Added G4VModel::GetG4PhysicalVolumeModel().
- Added G4VModel* argument to G4BoundingSphereScene constructor.
  Both the above are to facilitate access to a model, if it exists, and
  to invoke methods of G4PhysicalVolumeModel if it is one.
- Added code to curtail G4PhysicalVolumeModel search in G4BoundingSphereScene.

24th July 2001  John Allison  (modeling-V03-02-02)
- Added G4VModel::SetExtent(const G4VisExtent&).

3rd February 2001  John Allison  (vis-V03-00-02)
- Tidied for CodeWizard.

29th May 2000  John Allison
- Moved code for maintaining depth, physical and logical volume
  pointers from VisitGeometryAndGetVisReps to DescribeAndDescend to
  handle daughters of replicas correctly (Guy Barrand).

22nd May 2000  John Allison  (modeling-V01-01-00)
- Added G4VTreeGraphicsScene (DTREE).
- Commented out pVPV->SetCopyNo(n) on Makoto's advice in
  G4PhysicalVolumeModel.cc.

vis-V01-01-01  12th April 2000  John Allison
- Made G4PhysicalVolumeModel::DescribeSolid virtual.
- G4PhysicalVolumeModel::DescribeSolid no longer deals with composite
  solids - now programmed into CompositeSolid::CreatePolyhedron, where
  CompositeSolid means G4IntersectionSolid, G4SubtractionSolid and
  G4UnionSolid.
- G4PhysicalVolumeModel::DescribeSolid no longer deals with displaced
  solids - now programmed into G4DisplacedSolid::CreatePolyhedron.
- Added G4LogicalVolumeModel::DescribeSolid, which explicitly adds
  components of composite solids as white forced-wireframe objects.
