Newton Raphson Fractal 05, basic case with basic colors

'Pixel Bender' -experiment with Newton Fractal for roots of (z-a)(z-b)(z-c)(z-d) - or in this case z^4-1.

I unrolled the main loop, with 16 iterations - still way too slow for flash player, what a had in mind was a fractal fill for actionscript

Done
