maximized state and normal frame size lost after hide/show

[Cosmin Apreutesei]

I noticed that if I unmap a window, when I map it back, it's maximized
state along with the restore-to size and position are all lost (Ubuntu
10). Is there a way to get the normal size/pos so I can put it back
before mapping? Or do I have to track it myself through resize events
(if that's even possible)?

Thanks.
