GNUstep-back fix

[Wolfgang Lux]

Hello,

the following patch fixes an issue when running under Apple's
quartz-wm window manager and possibly other window managers
as well. In order to work around a problem that is attributed
to the Metacity window manager, XGServerWindow's private function
setNormalHints sets the minimum and maximum size of a non-resizable
window to the window's current size. At least for Apple's quartz-wm
this not only prevents the user from resizing the window, but also
prevents resizing the window programmatically. (In fact, the resize
operation is performed, but the window manager then resizes the
window back to its original size.) The attached patch attempts
to work around the work around by temporarily removing the minimum
and maximum window size hints before a window is resized in
method -placewindow::.
