轻量的AS3 Tween类 – TweenLite

http://blog.greensock.com/tweenliteas3

特点：

• Minimize file size – 缩小文件尺寸
• Minimize the amount of code required to initiate a tween – 减少任务代码
• Tween multiple properties with a single call (including a MovieClip’s volume and color)  – 多属性同一代码调用
• Maximize performance – 增强性能
• Build in the ability to call any function when a tween has completed and pass any number of parameters to that function – 完成时事件控制
• Build in the ability to call any function when a tween starts and pass any number of parameters to that function – 初始化事件控制
• Allow the user to set a delay before the tween takes effect (useful when looping through an array and you want to have tweens activate in a sequential way) - 启动时的延迟接口
