        * gui/greeter_item_pam.c: Add pam-error-logo item type.
        * gui/greeter/greeter_item.h, gui/greeter/greeter_canvas_item.c,
          gui/greeter/greeter_geometry, gui/greeter/greeter_parser.c: Add item
          type button to use a real GTK+ button, this better supports
          accessibility.  Add "startover" string to stock, this better name
          for the "Cancel" button was recommended.
        * gui/greeter/themes/happygnome/happygnome.xml,
          gui/greeter/themes/happygnome/happygnome-list.xml,
          gui/greeter/themes/circles/circles.xml: Updated theme to use real
          GTK+ buttons.  Now says "Start Over" instead of "Cancel" on the
          button.
        * gui/greeter/greeter_events.c, gui/greeter/greeter_item.c: Code
          cleanup.
        * docs/gdm/gdm.xml: Add docs for new features and the gtk-theme
          greeter element feature added in 2.12 but after string-freeze, so
          docs couldn't be updated then.
