Hacking only CreateWindow means the driver will get calls for windows
that it hasn't created, that's ugly. Also the window station can change
dynamically, so we need better mechanisms to handle that sort of thing.
Ideally the driver would also have support for it, so that you could do
things like having separate window stations for separate X displays
within the same session.
