I am not sure about this, but honestly I don't really know much about 
IDirect3DTexture2::Load is supposed to work. When I ported ddraw.dll to use 
wined3d I only did routine adjustments to the code to cope with the wined3d 
objects. I think Lionel Ulmer wrote the original code, maybe he can comment 
on it?

I think we really need a few unit tests for this method. From the docs, it 
seems that this method is related to IDirect3DDevice9::LoadTexture, maybe we 
can map it to WineD3D's loadtexture.
