TweenLite, Flash渐变第三方模块

DESCRIPTION:
 Tweening. We all do it. Most of us have learned to avoid Adobe's Tween class in favor of a more powerful,
 less code-heavy engine (Tweener, Fuse, MC Tween, etc.). Each has its own strengths & weaknesses. A few years back,
 I created TweenLite because I needed a very compact tweening engine that was fast and efficient (I couldn't
 afford the file size bloat that came with the other tweening engines). It quickly became integral to my work flow.
