+//	Name:		NormalSwizzleShader
+//	Author: 	Kenan Chabuk (@Kenamis)
+//	This works in conjunction with the AtlasNormalShader that swizzles the alpha to red channel of the packed normal and blends them.
+//	Then this post effect re-swizzles the normal into the packed format for use with standard shaders.
