Using: TweenMax 1.14.1 The TweenMax docs say that setting TweenMax.defaultEase sets the default easing on TweenMax tweens. As far as I can tell, it doesn't work. Instead, it seems, I need to set TweenLite.defaultEase. (I've also noted that the default for TweenMax.defaultEase is undefined, but the default for TweenLite.defaultEase is Power1.easeOut.) It seems like this is a bug either in the docs or in the code.
