Having slept on the problem I don't think many games (if any) are going to use ARGB colours for
anything other than the diffuse and specular colour inputs, all the textures will be in the
correct order and so are the shader constants. If a game does use any unexpected colours inputs
the shader can always be compiled with those inputs swizzled too.
