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.
