Fix miniwindows auto-arranging bug
With this patch, minimized windows do not reshuffle anymore.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=361241
where Martin Hinsch reported:
"The behaviour of icons (minimized applications) is severely broken when
automatic placement is switched on.
* When switching the workspace icons often stick thereby covering (and
hiding) icons on the workspace one is switching to.
* After minimizing an application, clicking (singly or doubly) on one of
the icons causes all of them to reshuffle, usually in a way that the
icon in question changes its place (which is extremely annoying).
* Icon placement ignores the dock so that icons disappear behind
it/cover it.
All of these suddenly appeared about a year ago (I think with 91.0). The
problems are not architecture-specific since they occur in exactly the
same way on my pentium machine. Wiping the complete configuration (rm -r
~/GNUstep) did not make a change either."
