&&&&& 上次讲的是Transparent Shader Family，他们是绘制半透明的对象使用的，但他们并不能满足我们全部的要求。
&&&&& Transparent Cutout Shader Family是对半透明对象Shader的一类补充，与Transparent Shader Family有所区别的是：Cutout Shader Faimily中的Shaders不允许绘制部分透明的区域。就是说，使用这种Shader绘制出来的对象，要么是全透明，要么是半透明。使用这个家族Shader的对象通常用来转换和接受阴影。半透明对象中常有的排序问题在使用这类Shader的时候不存在。
&&&&&& 这个家族里面的所有Shader都定义了一个Alpha Cutout的数值，纹理中alpha大于Alpha Cutout数值的，被认为是不透明的，否则就是全透明的。通过这个alpha cutoff数值，我们可以控制哪些区域全透明，哪些区域不透明。（也可以用来做一些动画的控制，你懂的）
&&&&&& 这个家族只包含了6个Shader，分别是
&&&&&& (1) Transparent Cutout Vertex-Lit
&&&&&& (2)Transparent Cutout Diffuse
&&&&&& (3) Transparent Cutout Specular
&&&&& (4) Transparent Cutout Bumped Diffuse
&&&&&& (5)Transparent Cutoff Bumped Specular
&&&&&& (6) Transparent Cutout Soft Edge UnLit
&&&&&& 这个是官方文档里面没有记录的，估计是后面新加入的。这个Shader绘制物体的正反两面，不受光照影响，常常用来绘制花草，树木，叶子。
&&&&&& 他包含了两个Pass，第一次将对象中Alpha大于alpha cutoff的部分以不透明的方式绘制。第二次关闭写zbuffer后，以半透明的方式绘制Alpha小于alpha cutoff的部分。这样做可以将绿草这种半透明的对象不需要排序就能绘制正确。
