稳扎稳打Silverlight(11) - 2.0动画之ColorAnimation, DoubleAnimation, PointAnimation, 内插关键帧动画

作者：webabcd

介绍
Silverlight 2.0 动画：
    ColorAnimation - 在两个 Color 值之间做线性内插动画处理
    DoubleAnimation - 在两个 Double 值之间做线性内插动画处理
    PointAnimation - 在两个 Point 值之间做线性内插动画处理
    内插关键帧动画 - 在 Color 或 Double 或 Point 动画中内插关键帧，以做线性, 离散, 三次贝塞尔曲线的动画处理
    动态改变动画 - 通过程序控制，动态地改变动画
