2.0图形之基类System.Windows.Shapes.Shape

介绍
Silverlight 2.0 图形：基类System.Windows.Shapes.Shape（Ellipse, Line, Path, Polygon, Polyline, Rectangle都继承自抽象类System.Windows.Shapes.Shape）。
    Fill - 填充（System.Windows.Media.Brush类型）
    Stroke - 笔触（System.Windows.Media.Brush类型）
    StrokeThickness - 笔触尺寸
    Stretch - 拉伸值 [System.Windows.Media.Stretch 枚举]
    StrokeDashArray - 虚线和间隙的值的集合 [System.Windows.Media.Stretch 枚举]
    StrokeDashCap - 虚线两端（线帽）的类型 [System.Windows.Media.PenLineCap 枚举]
    StrokeStartLineCap - 虚线起始端（线帽）的类型 [System.Windows.Media.PenLineCap 枚举]
    StrokeEndLineCap - 虚线终结端（线帽）的类型 [System.Windows.Media.PenLineCap 枚举]
    StrokeDashOffset - 虚线的起始位置。从虚线的起始端的 StrokeDashOffset 距离处开始描绘虚线
    StrokeLineJoin - 图形连接点处的连接类型 [System.Windows.Media.PenLineJoin 枚举]
    StrokeMiterLimit - 斜接长度 与 StrokeThickness/2 的比值。默认值 10，最小值 1
