+Auto-Updating Contents
+----------------------
+
+Contents which update automagically (e.g. animated gifs) should, when an update
+occurs, send a message up to the content's users to notify that a change has
+happened. It is then left up to the users to decide what to do about it.
+
+Thus, for animated GIFs, which update off the scheduler, when the scheduled
+callback happens, the content handler should update its frame counter, and
+send a content changed message. On receipt of the message, the relevant user(s)
+should decide what to do (if anything -- if the GIF's not visible, there's no
+point decoding the new frame and attempting to display it).
