    Avoid shrinking windows with Gtk+ 3.20.3
    
    Problem reported by Matthias Clasen (Bug#23144).
    This was fixed in a different way in master.
    Do not merge to master.
    * src/xterm.c (handle_one_xevent) [GTK_CHECK_VERSION (3, 20, 3)]:
    Do not call xg_frame_resized in the MapNotify case.
