    app: gimp_device_info_get_device_coords(): workaround for XI2 b0rk
    
    for the time being, use gdk_window_get_device_position() instead of
    gdk_device_get_axis() for X and Y, which gets rid of subpixel
    coordinates, but at least returns values != 0. Also, don't ask
    keyboard devices for coordinates.
