 The Frame makes heavy use of trays, with one on each edge.  The design
 specifies that each edge of the frame should correspond to, and align
 with, a separate corner of the screen, which goes hand in hand with the
 design for the new notification system.  I think it's important -- both
 since we're shifting things around now anyway, and since we hope to make
 good use of the notification system for better feedback -- to have this
 alignment issue fixed for the next release.

 The technical details of the problem concern incompatibilities between the
 "model" and "view" used to represent the tray (gtk.Box and gtk.Toolbar),
 only one of which supports pack_start/end. (At least, I think this is the
 problem...)
