Qt window placement

[Ethan A M. <sf...@us...>]

At some point between 4.6 and current CVS, the initial placement of 
Qt plot windows has changed.   

It used to be that the Qt plot window would open nicely in some unoccupied
part of the screen, probably because that is how I set the window manager
policy.

Now it always opens in the center of the screen, which is probably the
worst possible place.  Changing the window manager placement policy
has no effect.

How can we restore the previous behaviour?
