There's no easy way to specify the material component that a texture should
affect (such as emissive, specular) in plain OpenGL.
The way to go these days is a fragment shader. You could also use a multi-pass
technique to apply another texture.
(Maybe register combiners offer something useful but I'm not sure about that.)
