The problem is that generally you can't really be sure if you are maximized or 
just big.

But with a relative new window manager, there are properties we can look at to 
deduce what to do or not do, so we can cover those cases at least (i.e. all 
KDE, Gnome, XFCE and some more).  I'll see what I can come up with.
