   * @brief extends vtkContextInteractorStyle to fire start/end interaction events.
   *
   * vtkPVContextInteractorStyle simply extends vtkContextInteractorStyle to fire
   * vtkCommand::StartInteractionEvent and vtkCommand::EndInteractionEvent to mark
   * the beginning and end of the interaction consistent with
   * vtkPVInteractorStyle (used for render views).
