30th May 2010  John Allison  (greps-V09-03-02)
- G4VVisManager: Added Draw(const G4VDigi&) and FilterDigi(const G4VDigi&).
- G4VGraphicsScene: Added AddCompound (const G4VDigi&).

29th May 2010  John Allison  (greps-V09-03-01)
- G4VVisManager:

  o Added DispatchToModel(const G4VTrajectory&), i.e., without i_mode, to
    distinguish usage and in preparation for i_mode migration.

7th May 2010  John Allison  (greps-V09-03-00)
- G4VVisManager: Added a public static boolean flag,
  IsDefaultDrawTrajectory, to assist deprecation of i-mode trajectory
  drawing parameter.  After 10.0, it can be removed.

  of doing multiple boolean operations. This permited to solve most
  tricky cases in LHCb visualization.

3rd April 2007  John Allison  (greps-V08-02-01)

  an expendable copy on the heap, thus following the behaviour of
  CreateAttValues in trajectories, hits, etc.  This achieves consistency
  of behaviour and user expectation; the user must delete after use.

- Introduced Establish/DecommissionSpecials (G4PhysicalVolumeModel&)
  in place of BeginModeling (G4PhysicalVolumeModel&).

- Tagged.

April 9th, 98 G.Cosmo
- Porting on DEC-cxx 6.0.
  Removed meaningless usage of "const" qualifier from functions
  return type for basic types by value. Modified files: G4NURBS.cc

greps-00-05-02  4th April 1998  John Allison
- Re-engineered maintenance of current depth, etc.  Needed new method
  G4VGraphicsScene::BeginModeling (G4PhysicalVolumeModel&) in
  graphics_reps.  The result is much cleaner model and modeling
  parameters classes.  Also, the current depth, physical volume and
  logical volume are immediately available as protected pointers in
  G4VScene.

HEAD  3rd April 1998  John Allison
- Added GetWorld/ScreenDiameter/Radius to G4VMarker.

April 2, 1998 G.Barrand :
- G4Polyhedron.cc : add a G4double cast to help NT/Visual compiler.

greps-00-05-01  26th March 1998  John Allison
- Removed #if defined(__DECCXX) || defined(WIN32) from G4NURBS.hh.
- Improved comments in G4VMarker.hh

7th January 1998  John Allison
- Added arguments to PreAddThis in G4VGraphicsScene.hh.
- Added virtual destructor to G4VVisManager.

December 19, 97 G. Cosmo - (alpha03)

- Created.
