  // First, a view should decide when to re-visit the G4 kernel.
  // Sometimes it might not be necessary, e.g., if the scene is stored
  // in a graphical database (e.g., OpenGL's display lists) and only
  // the viewing angle has changed.  But graphics systems without a
  // graphical database will always need to visit the G4 kernel.
