稳扎稳打Silverlight(10) - 2.0其它之Transform详解，以及UIElement和FrameworkElement的常用属性

作者： webabcd


介绍
Silverlight 2.0 其它：
    RenderTransform - 呈现位置的转换（System.Windows.Media.Transform类型）
        TranslateTransform - 平移转换
        RotateTransform - 旋转转换（顺时针）
        ScaleTransform - 缩放转换
        SkewTransform - 扭曲转换
        MatrixTransform - 仿射矩阵变换
        TransformGroup - 多个 Transform 组成的复合转换
    RenderTransformOrigin - 位置转换的中心点
    Clip - 容器的剪辑区域（System.Windows.Media.Geometry类型）
    IsHitTestVisible - 命中测试是否可见
    Opacity - 不透明度。0 - 1之间
    OpacityMask - 不透明蒙版（遮罩）（System.Windows.Media.Brush类型）
    UseLayoutRounding - 是否使用完整像素布局
    Cursor - 鼠标移动到 FrameworkElement 上面时，鼠标指针的样式
    Margin - 容器边缘与边缘之外的空白距离（像素值：上下左右；左右,上下；左,上,右,下）
    Tag - 保存一些额外的信息（System.Object类型）
