Owen W. Taylor 26a074588b 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.
