 The attached sugar and sugar-artwork patches add three new home layout
 views: square, triangle, and spiral.  It also fixes the ring view scaling
 code, so that the ring view better handles large numbers of activities.
 Some refactoring of the layout code was done to make it easier to add new
 layouts in the future (requiring patches to fewer separate locations in
 the code).

 With the fixes, the home view layouts can handle up to 120 or so
 activities.  The spiral layout doesn't have any overlapping icons with
 this number of activities; the mesh layout has a small number (since grid
 layout gives up if it can't resolve conflicts); and the ring, square, and
 triangle layouts start overlapping icons, but remain usable.
