[David Zeuthen <davidz src gnome org>]

commit 9b55de1c6b0bb0acb2738ec36ba83f7c7e3aeef6
Author: David Zeuthen <davidz redhat com>
Date:   Mon Mar 14 13:18:03 2011 -0300

    polkit: Make dialogs look more like the mockups
    
    The mockups are here
    
     https://live.gnome.org/GnomeShell/Design/Whiteboards/AuthorizationDialog
    
    Detailed changes
    
     - Don't use an icon for root
     - For root, show Administrator in red
     - Nuke icons for info and error messages
     - Make error messages yellow
     - Use 10pt size for error and message labels, not 12px
     - Don't make the dialog change size when (single-line) error/info
       messages appear
     - Spacing fixes
     - Show "Sorry, that didn't work. Please try again" if authentication fails
     - Don't cancel the PolkitAgentSession if the session has already completed
