  /*
   * spinner.hh --
   *
   *      The spinner widget instantiated by the SpinnerAction. The widget is
   *      intentionally very lightweight because we expect multiple instances
   *      linked to a single action - which is where the heavy lifting should
   *      take place.
   *
   *      So, the widget only defines the mechanics of switching frames.
   *      Loading the frames and setting an animation policy is left to the
   *      action.
