-/** A class representing the swizzle access pattern for a texture. Note that if the texture is
- *  an alpha-only texture then the alpha channel is substituted for other components. Any mangling
- *  to handle the r,g,b->a conversions for alpha textures is automatically included in the stage
- *  key. However, if a GrProcessor uses different swizzles based on its input then it must
- *  consider that variation in its key-generation.
