Perturbation-style formulas depend on the #dz value remaining small enough
for fixed-point arithmetic. I managed to sabotage myself by setting a high
bailout value of 1e20 on this deep zoom with perturbation.
After reducing the bailout to 1e10 the formula worked beautifully.
(I wanted a high bailout because I was using smooth coloring)
