  /**
   * The Timeline Update Event.
   * 
   * This event is dispatched by a Tween Timeline every time it updates, which can happen a lot of times per second,
   * so be careful about listening to this event unless you absolutely require it.
   * 
   * Listen to it from a Timeline instance using `Timeline.on('update', listener)`, i.e.:
   * 
   * ```javascript
   * var timeline = this.tweens.timeline({
   *     targets: image,
   *     ease: 'Power1',
   *     duration: 3000,
   *     tweens: [ { x: 600 }, { y: 500 }, { x: 100 }, { y: 100 } ]
   * });
   * timeline.on('update', listener);
   * timeline.play();
   * ```
   *
   * @event Phaser.Tweens.Events#TIMELINE_UPDATE
   * 
   * @param {Phaser.Tweens.Timeline} timeline - A reference to the Timeline instance that emitted the event.
