// A "state dependent" service class for G4VisManager.
// John Allison  29th November 1999

// G4VisStateDependent is "state dependent", i.e., it is notified on
// change of state (G4ApplicationState).  This is used to message the
// G4VisManager to draw hits and trajectories in the current scene at the
// end of event, as required.
