I'll implement EXT_texture_env_combine instead. I hope, I have something
working until next week. The EXT_texture_env API can be expressed in terms
of EXT_texture_env_combine, but I'm not shure if this makes sense.
As far I know yet, Mesa would be the only OpenGL implementing this 
extension. It's a bit easier to use, but less flexible.

I will write this extension so that it defines a new mode for
EXT_texture_env_combine.

This would be great.
Could you look, if all other modes are supported, too ??
