Added

• Convenience method on Scene to determine whether it is the current scene. Scene.isCurrentScene() (#982)
• New PointerEvent.stopPropagation() method added. Works the same way as (https://developer.mozilla.org/en-US/docs/Web/API/Event/stopPropagation) (#912)

  • pause - on playback pause;
  • stop - on playback stop;
  • emptied - on data cleanup(f.e. when setting new data);
  • resume - on playback resume;
  • playbackstart - on playback start;
