[gtk+/nth-child: 4/22] API: Add gtk_widget_path_set_region_flags()

[Benjamin Otte <otte src gnome org>]

commit 665d1a18588646f3f878076c5b68a2102fe589d8
Author: Benjamin Otte <otte redhat com>
Date:   Wed May 25 19:58:43 2011 +0200

    API: Add gtk_widget_path_set_region_flags()
    
    And gtk_widget_path_get_region_flags(). This is needed to make
    nth-child(first) etc work for widgets and not just for regions.
