%(BoxStyle:table)s

        mutation_scale : float, default: 1
            Scaling factor applied to the attributes of the box style
            (e.g. pad or rounding_size).

        mutation_aspect : float, default: 1
            The height of the rectangle will be squeezed by this value before
            the mutation and the mutated box will be stretched by the inverse
            of it. For example, this allows different horizontal and vertical
            padding.
