Well... im really a noob (learning c since 3 days i think oO ) could you
please explain your code? Im not getting totally through it...

I dont understand what this is good for... and ive no idea what is done
in the different d3dtss calls... i really do what i can, but i think i
lack experience...

*Dou* my fault...

Alright.

Okay, they dont seem to break anything and i guess its quite painfull to
figure out what they do, so ill leave them for now.
