(in reality, the method works in some conditions and fails in others, so must be manually tweaked.)
The method is;
1. calc an iter of the fractal. 2. calc the newmag. 3. mul oldmag by a factor. It seems that 0.7 is a good one. In other words we keep track of the magnitude changes but the last one is more important than the first. 4. add newmag to oldmag 5. repeat to point 1 around 70 times 6. the final mag must be divided by itercount 7. take log() of finalmag 8. emboss the plane z=0 by finalmag
