Not entirely, there's DwmEnableComposition() and DwmIsCompositionEnabled() in
dwmapi. I think it would make sense for Wine to at least properly implement
those.

As for actually disabling compositing for D3D applications, I'm not sure how
this is handled on Windows for pre-Vista applications, but applications that
are aware of it usually disable it themselves.
