Perhaps nothing. On w32 maximized windows covers the area that are not
reserved by the taskbar (or other bars). I think this is the area that
we should return (as I have said before).

Maybe a bit of confusion comes in because the taskbar only reserves
this area on w32 if it is not automatically hidden.
