[Johan Dahlin <johan src gnome org>]

commit 680a2e04ac4f80ad16e820d3f753519477c988aa
Author: Johan Dahlin <johan gnome org>
Date:   Wed Mar 14 15:20:53 2012 -0300

    Add bw-compatible arguments to Gtk.Adjustment
    
    The argument used to be called page/step_incr, if they
    are found map them to the existing properties for extra
    compatibility.
