Brian Osman 8c3d183cc2 Rename SkSL 'srgb_unpremul' to just 'color' 
Added comments to explain the semantics (both what's expected when you
set the uniform, and what you see in the shader). The old name was
confusing, because it sounded like you got an sRGB color in the shader.
This is terse, but I think it's the cleanest syntax - and for embedding
clients, they can use C++ (etc.) API to require that color uniforms are
assigned from color types.
