In a quake context, I suspect iqm models should use the same skin concepts as alias models. I'll probably be proven wrong, but it should make things nicer for now, especially with forward lighting. However, Mr Fixit is too bright because the skin isn't set up correctly. Deferred is getting more and more smashed, but I'll fix that up when I've got forward "done".
