Go faster!

I've done some further investigation of yesterday's excruciatingly slow fractal, and discovered that in setting it to render larger, it had indeed gone into arbitrary precision, which accounts for some of the slowness. I also figured out that I could switch to the associated Julia set and get an almost identical effect without having to zoom so deeply. So I've got a different version rendering now, and it says it has a mere three hours to go. Hooray!

Some tinkering with a nearby Mandelbrot region, and some nice quick simple orbit trap coloring, has given me an idea for a possible label design. I'm not sure about the color. It seems somewhat too dark.
