[balsa/wip/gtk4: 239/351] Use gtkwidget_get_realized

[Peter Bloomfield <peterb src gnome org>]

commit 7b3ae4760111007c7aa19cc27269ca21e854689f
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Tue Mar 20 20:32:42 2018 -0400

    Use gtkwidget_get_realized
    
    to check whether a widget has been realized, instead of using
    gtk_widget_get_has_surface, which indicates something totally different.
    
    More fallout from the GdkWindow rename.
