The problem is the implicit surface (IS) destruction in wined3d (device 
and swapchain). Release won't destroy them, so wined3d needs a way to 
destroy IS. I solved it with setImplicit(false); release;.

Another posibility would be to move the IS destruction to d3d8/d3d9. 
There we would have more control over the IS, and the parentDevice 
problem from patch [5] would also be solved. But it means some code 
duplication in d3d8/d3d9.

I went for less code.
