In principle there are functions like MonitorFromWindow() that would let you
find the monitor the window is on. They probably don't work correctly in Wine
at the moment because we just pretend there's one large monitor though. And
yeah, I think the Windows behavior is to set the gamma based on which window
currently has the focus, or something along those lines.
