  // Description:
  // The interaction state may be set from a widget (e.g., vtkBoxWidget2) or
  // other object. This controls how the interaction with the widget
  // proceeds. Normally this method is used as part of a handshaking
  // process with the widget: First ComputeInteractionState() is invoked that
  // returns a state based on geometric considerations (i.e., cursor near a
  // widget feature), then based on events, the widget may modify this
  // further.
