What is it ? : This coloring draws approximations of the Hilbert Curve, a fractal covering
the plane. It should be used on a "Pixel"like formula.
The Parameters : Style : Allow to modify the look of the Hilbert Curve. Thickness : Modify the way the distance is computed. The smaller this parameter is, the thinner the curve will look. Number of iterations : Successive iterations are used to approximated
the curve. With an infinite number of iterations, it covers the plane.
