Whoa!  There are definitely some issues to address here...  Kicker actually
does set the struts right on those "inner" edges, which really throws things
off in compiz.  I'll see if I can't put together a couple patches to try to do a
better job of handling the struts when they're set, and hacking around the
fact that gnome-panel doesn't set them (currently).
