    Bug 591114 - Remove expanded background
    
    The "expanded background" that is behind the workspaces etc. in the overview
    should be removed.  It isn't in the designs, it is distracting, and it breaks
    the overview metaphor.
    
    At least temporarily, just make the background of the overview black.
    Change the pane popup to black as well, but keep a blue border so that
    it is visually distinguished from the background.
    
    Based on a patch by Colin Walters, with fixes from  Marina Zhurakhinskaya.
