How do I go about bumpmapping a simple polygon (in my case, a square)? I've already imported the normal map (as a bitmap) and can use it as a texture, but there seems to be a shit-ton more functions that I need to call for it to actually used as a normal map on the polygon.

Can you even do normal mapping in OpenGL while still using the fixed-function pipeline? I was under the impression that you had to write a shader program to do it. Though, knowing OpenGL there's probably some pre-SL1.0 extensions which aren't supported on half the chipsets to do normal mapping, but what the fuck.
