Commit: Martin Rudalics <address@hidden>

    Fix a few issues with latest GTK scaling changes
    
    * src/xfns.c (Fx_display_monitor_attributes_list): Call
    gdk_screen_get_monitor_scale_factor only for GTK versions
    3.10..3.21.
    * src/xterm.c (x_set_offset): Call xg_get_scale for GTK only.
