This is a port of the Metacity Clearlooks theme, pieced together from screenshots of the Metacity theme.

Inspired by "Clearlooks-Xfce-Colors" from here: http://xfce-look.org/content/show.php/Clearlooks-Xfce-Colors?content=90384

Mine has a working "restore" button; the one linked above uses the restore button for disabled windows but *always* shows Maximize for active windows, which is an error. Mine is more accurate to the Metacity theme.
