[PATCH 2/5] d3dx11: Made texture loader use wined3dformat instead of d3dformat.

I somewhat doubt it. It wasn't too hard to use the d3dx9 parts for d3dx11, and 
it shouldn't be too hard to make it a good generic version. It would make both 
d3dx9 and d3dx11 simpler, while providing modular abstraction. Just loading a 
texture or texture information is something that can be standalone.

I'm open to change of course, but I'd like to understand the reason behind it. 
It's not linked to wined3d anymore, only uses the intermediate imageformat. 
Since a generic imageloader can't rely on DX9 types nor on DX11 and since I 
didn't want to reinvent the wheel, I just used the implemenation at hand: 
wined3dformat.
