public class Fractal extends JRootPane implements ActionListener
Application which calculates fractals using a multithreaded system. The formula define the fractals uses complex numbers the default is z = `z^2 + c`, the `c` value is given by the coordinates of the individual pixels, and the color depends on the number of iterations it takes before the value diverges. The equation of the fractal can be changed, but must only use the variables `z` and `c`. The formula for colors can also be changed. The default is `[ (itts % 10)/10 ,( itts % 100)/100, (itts % maxItts)/ maxItts ]` the result of evaluation should be a vector with three item which values between 0 and 1. The formula for colors can contain `z` and `c` as well as `itts` the number of itts before divergence `maxItts` the maximum number of iterations specified. This value is set in a field in the main window. For example `if(itts==maxItts, [0,0,0], [ (re(z) + 4)/8, (4-re(z))/8, (im(z)+4)/8] )` colors by the position of z after the iteration, or black if it did not converge.

The default region shown is (-2,-2) .. (2,2). Double-clicking zooms in centered on the mouse position, right-clicking zooms out, and dragging the mouse shifts the domain.

For details on how the thread are implement see the `FractalCanvas` class. See main thread documentation.
