Remove v_glslgamma cvar (now assumed to be 1) and corresponding code like R_DrawGamma.

RENDERPATH_GL1* paths no longer support bloom.

Fix a bug in D3D9 renderpath where SHADERPERMUTATION_GAMMARAMPS would crash due to using the wrong variable for the texture unit.

Enable GL_ARB_texture_non_power_of_two on OSX again - the old OSX versions and corresponding hardware that had issues are long gone.
