    The :py:func:`register` function is used to register additional viewers::

        from PIL import ImageShow
        ImageShow.register(MyViewer())  # MyViewer will be used as a last resort
        ImageShow.register(MySecondViewer(), 0)  # MySecondViewer will be prioritised
        ImageShow.register(ImageShow.XVViewer(), 0)  # XVViewer will be prioritised

    :param viewer: The viewer to be registered.
    :param order:
        Zero or a negative integer to prepend this viewer to the list,
        a positive integer to append it.
