Sure. At this point I think we mainly care that it's consistent with
dxgi_device_init().
As far as dxgi is concerned though, I think it's mostly a matter of
making the result of d3d_level_from_caps() from wined3d/directx.c
available somewhere. Perhaps as a separate call, perhaps just as part
of the wined3d_caps structure.
