/**
 * A semantic event which indicates that an Animation-defined action occured.
 * This high-level event is generated by an Animation Object when
 * an action occurs (such as a change in progress).
 * The event is passed to every <code>AnimationListener</code> object
 * that registered to receive such events using the Animation's
 * <code>addAnimationListener</code> method.
 * <P>
 * The object that implements the <code>AnimationListener</code> interface
 * gets this <code>AnimationEvent</code> when the event occurs. The listener
 * is therefore spared the details of processing individual selection, and can
 * instead process a "meaningful" (semantic) event.
