+// 圆角裁剪（支持任意宽高纹理）
+// 原理：
+//  1. 正方形纹理的圆角原理参考 https://www.cnblogs.com/jqm304775992/p/4987793.html 
+//  2. 正方形纹理的圆角代码参考 yanjifa/shaderDemor 的 https://github.com/yanjifa/shaderDemo/blob/master/assets/Effect/CircleAvatar.effect
+//  3. 上述皆为只针对正方形纹理做的操作，如果是长方形的纹理，那么圆角就会有拉伸后的效果，最后变成看起来就不是圆角了，本特效支持任意长方形做圆角
