// Note: The mandelbrot pattern was put into Vivid almost as a joke.
// Currently the format for specifying it is terrible. The
// first two parameters of the scale value determine the
// x y scaling of the set while the 3rd parameter determines
// the maximum number of iterations. The result of the
// iteration calculation is then scaled by the max number of
// iterations to determine the relative percentages of the
// surface parameters for that point. Once I figure out a
// resonable way of doing this Mandelbrot and Julia sets
// will become a real part of Vivid.
