wp 之path详细 以及一个关于LinearGradientBrush 的动画

首先LinearGradientBrush 画刷竟然包含Trsanslate 属性也就有x，y 属性

<Path HorizontalAlignment="Center"
                VerticalAlignment="Center"
                StrokeThickness="25"
                Data="M 100    0
                      C  45    0,    0   45, 0 100
                      S  45  200,  100  200
                      S 200  150,  250  100
                      S 345    0,  400    0
                      S 500   45,  500  100
