This looks good to me. I'm not sure what the game is doing makes a whole lot of
sense though as it's submitting unsigned byte data. I guess if it's only
needing positive offsets that's ok (but wouldn't make any sense with shaders).

If that's a problem related to that texture format, you could try setting the
env var MESA_EXTENSION_OVERRIDE=-GL_ATI_envmap_bumpmap in this case the game
should never try to use that texture format.
