[Jasper St. Pierre <jstpierre src gnome org>]

commit 575963bee7f132656dcdb254a8e2e89c88419fd5
Author: Jasper St. Pierre <jstpierre mecheye net>
Date:   Tue Apr 29 15:55:55 2014 -0400

    window: Turn grab_op_begin / grab_op_ended into vfuncs
    
    And move the grab_resize_popup management to the X11 window class,
    as this is only used under X11.
