- Add dummy textures so texture operations which dont reference the
texture can work.
- Support 2d and 3d textures properly.
- Reapply the texture state information as textures get set, as opengl
stores the state along with the bound texture whereas directx uses the
current state information during the draw stage.
- 3rd attempt to sort out lighting, for programs which dont set normals.
- Temporarily silence some unnecessary fixmes.
