Effectively disable _TexEnvProgram before calling _swrast_DrawPixels().
It's OK to use _TexEnvProgram regardless of the texture state, but if fog is also enabled, the fragment program is lacking the actual fog computation so fogging doesn't appear. Fixing this might involve a new _MaintainFogProgram field and related code. For now, just disable the _TexEnvProgram and let swrast handle everything.
