   the figure's click callback, and sets the mouse pointer to a watch.

   BUSYFIGURE(FIGUREHANDLE, BUSY, STATUSSTRING, OLDINFO) also sets status
   information via the Matlab 'setstatus' function; passing an empty
   string will skip this call.  (Note that passing in an empty string
   does _not_ set the status to ''.)  When freezing, the figure's
   original pre-freeze state is returned; pass this structure as the
   fourth argument when unfreezing to restore state.</pre></div>
