Minor update

2.1.1 - July 1 2015

• Add Animation.timeline getter

• Add AnimationEffect.parent getter

• Make AnimationEffectTiming (returned by AnimationEffect.timing) attributes mutable

• Expose the Animation constructor

• Change custom effects from AnimationEffects to onsample functions. Custom effects should now be created by setting the onsample attribute of a KeyframeEffect.

  For example, this is deprecated:

  var myEffect = new KeyframeEffect(
     element,
     function(timeFraction, target, effect) {
        target.style.opacity = timeFraction;
     },
     1000);
  var myAnimation = document.timeline.play(myEffect);
  

  and this should be used insead:

  var myEffect = new KeyframeEffect(element, [], 1000);
  effect.onsample = function(timeFraction, effect, animation) {
     effect.target.style.opacity = timeFraction;
  };
  var myAnimation = document.timeline.play(myEffect);
