        <!--
            线性动画一共有 3 种：ColorAnimation, DoubleAnimation, PointAnimation, 它们均继承自 Timeline
        
            Storyboard.TargetName - 附加属性，要进行动画处理的对象的名称
            Storyboard.TargetProperty - 附加属性，要进行动画处理的对象的属性
            BeginTime - 时间线在被触发 BeginTime 的时间后才能开始播放
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数]（可为正；可为负；可为空；默认值为 0）
            From - 动画的起始值
            To - 动画的结束值
            By - 动画从起始值开始计算，所需变化的总量（To 优先于 By）
            Duration - 时间线的持续时间
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数]
                Automatic - 自动确定
                Forever - 无限长
            AutoReverse - 动画完成后是否要原路返回。默认值为 false
            RepeatBehavior - 动画重复播放的时间、次数或类型
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数]
                nx - 播放次数。1x, 2x, 3x 
                Forever - 永久播放
            SpeedRatio - 时间线的速率的倍数。默认值 1
            FillBehavior - 动画结束后的行为（System.Windows.Media.Animation.FillBehavior 枚举）
                FillBehavior.HoldEnd - 动画结束后，UI 保留动画后的状态。默认值
                FillBehavior.Stop - 动画结束后，UI 恢复为动画前的状态
        
        
            注意：
            1、在 WinRT 中为了流畅的体验，部分动画被优化成了“独立动画”，即动画不依赖于 UI 线程
            2、但是也有一部分动画无法优化成“独立动画”，我们把这类动画称作“依赖动画”，其需要在 UI 线程上运行
            3、通过将 EnableDependentAnimation 设置为 true（默认为 false），开启“依赖动画”
            4、通过将 Timeline.AllowDependentAnimations 设置为 false（默认为 true），可以全局禁止开启“依赖动画”
        
            Independent Animation - 独立动画
            Dependent Animation - 依赖动画
