        The "options" hash may contain any or all of the following:

        max_iter => $iters

        limit => $limit

        bounds => [ $x1, $x2, $y1, $y2, $width, $height ]

        constant => [ $cx, $cy ]

    The default maximum number of iterations is 600. The default limit is 5.
    The default bounds is [-2.2, -1.1, 1.0, 1.1, 640, 480]. The default
    constant is [0.0, 0.0].

        my $julia = Math::Fractal::Julia->new();

        my $julia = Math::Fractal::Julia->new(%options);

        my $julia = Math::Fractal::Julia->new(
            max_iter => $iters,
            limit    => $limit,
            bounds   => [ $x1, $x2, $y1, $y2, $width, $height ],
            constant => [ $cx, $cy ],
        );

  set_max_iter
    Arguments: $max
    Return value: undefined

    Set the maximum number of iterations. The default value is 600.

        Math::Fractal::Julia->set_max_iter($max);

        $julia->set_max_iter($max);

  set_limit
    Arguments: $limit
    Return value: undefined

    The default value is 5.

    Return value: undefined

    The default values are (0.0, 0.0).

        Math::Fractal::Julia->set_constant( $cx, $cy );

        $julia->set_constant( $cx, $cy );

  point
    Arguments: $x, $y
    Return value: The number of iterations needed to exceed the limit or 0
    if the the limit is not exceeded.

    This function translates the coordinates using the bounds and then
    iterates.

        $iters = Math::Fractal::Julia->point( $x, $y );

        $iters = $julia->point( $x, $y );
