    Create a convolution kernel.  The current version only
    supports 3x3 and 5x5 integer and floating point kernels.

    In the current version, kernels can only be applied to
    "L" and "RGB" images.

    :param size: Kernel size, given as (width, height). In the current
                    version, this must be (3,3) or (5,5).
    :param kernel: A sequence containing kernel weights.
    :param scale: Scale factor. If given, the result for each pixel is
                    divided by this value.  the default is the sum of the
                    kernel weights.
    :param offset: Offset. If given, this value is added to the result,
                    after it has been divided by the scale factor.

    Create a rank filter.  The rank filter sorts all pixels in
    a window of the given size, and returns the **rank**'th value.

    :param size: The kernel size, in pixels.
    :param rank: What pixel value to pick.  Use 0 for a min filter,
                 ``size * size / 2`` for a median filter, ``size * size - 1``
                 for a max filter, etc.
