* Fresh new wallpaper as a PNG from gnome-look: http://gnome-look.org/content/show.php/Echo?content=137142 (By user hyperdude111, released as "do whatever you want") * Terminal bug fix for --geometry option, which was derping on height vs. width. * Compositor bug fix for wallpaper app not showing up at the bottom. Fixed by doing a better job of reordering the windows on a REORDER call (which we weren't actually doing).
