This preference covers where new SystemWindows are opened on the 
screen.  #reverseWindowStagger (which is on by default) causes windows 
to be opened in scattered areas of the screen, so that previously 
opened windows are less likely to be covered.  If it's off, new windows 
always open in the upper-left corner.  It doesn't have a huge impact on 
performance, but there seems to be less need for window redrawing when 
it's off, since it's always covering the previously opened window.

Anyway, I wouldn't mind a third type of window-placing behavior, 
something more like the Mac OS, where new windows are opened ~30 pixels 
below the previous window.
