Well, the WINED3DOK_NO3D is intended to say "you got your d3d object, but it 
will only do 2D drawing for you", and then its up to the client to accept 
this or not(Although I just see I forgot to release the returned object in 
this case). I don't see the problem.

I dislike create flags as much as dxVersion checks, and we should handle as 
much as possible without them. I feel strongly against using a create flag in 
patch 4. I just think passing in a flag to call X and call Y's behavior will 
miraculously change is ugly, although sometimes we can't avoid it.

The only places where I think we really need a create flag:
* Fixed buffer declarations
* D3D7 VB conversion / no conversion
* device vs surface palette
* and the COM priv data addref or no addref, although maybe there's a way to 
add a release() in ddraw
* the surface pitch alignment

That's quite a lot of them already
