What about improve D3D in wine?

[Mirek]

Hi i have found Nvidia SDK programs and demos, i can install it in wine 
and some D3D demos can even run, but almost all are someway broken, in 
Nvidia SDK there are even source codes for those demos, what about start 
improving Direct3D in wine with help of this demos? It should be easy to 
track what is wrong and what is right.
