world ipo-s

hey, is there any way (I haven’t found one yet) to control world ipo-s in the game engine?

I want to be able to control things like the fog depth, and the horizon color…

I would prefer to not have to use python, but if it is necescary…

In the Game Engine works only:
1)Object Ipos
2)Light Ipos
3)Camera Ipos

You have to work Rasterizer module to set Backgound color,setMist etc.
