Title: Crash because of shadows- 3.2

Crash!
Eception: OpenGL extension not supported: GL_ARB_shadow_ambient, required for Shadow Mapping

This happened when I turned shadow mapping on and started a custom game.
Also, this didn't show up in the error.log or crash.txt

I think this is because your graphics card is missing the extension and not really an error (info on the extension at http://www.opengl.org/registry/specs/ARB/shadow_ambient.txt ). Shadows may be implemented differently in a shader (when we get to it) but if it keeps coming up you may need to disable shadows.

This is apparently a problem for some NVidia cards.
Was recently discussed on the MG board and someone pointed out this post,

I guess someone should apply that patch some time ;)

Oops, I forgot about that post. I've applied the patch now.
