    The fog settings do not depend on wether the shader writes to oFog or not,
    instead they depend on the FOGVERTEXMODE and FOGTABLEMODE settings, and if a
    vertex shader is bound at all.
    
    It works the same way as with the fixed function, and having a vertex shader
    is the same as using pretransformed vertices, just that the fog coord comes
    from the shader instead of the specular color:
    
    FOGTABLEMODE != NONE: The Z coord is used, oFog is ignored
    FOGTABLEMODE == NONE, with VS: oFog is used
    FOGTABLEMODE == NONE, no VS, XYZ: Z is used
    FOGTABLEMODE == NONE, no VS, XYZRHW: diffuse color is used
