 Marco and I have been working on the activities donut to create the
 following behavior:

  * the current activity should always be at the bottom of the donut
  * when pressing alt-tab, the donut should rotate to place possible new
 current activities at the bottom.

 Back around the build 193 days, I had this working almost completely.  The
 biggest bug was that if the user pressed and released alt-tab too quickly,
 the homewindow wouldn't see the release event and wouldn't select the next
 activity.  It would be nice if someone who really knew X and GTK could
 help me to correctly hook up to alt-tab press and release events.

 I'm attaching the current version of the rotation code.  There is no alt-
 tab code yet.  Animation is also currently disabled ("1 frame per
 rotation") pending performance work.
