3cbe9afba5 mandelbrot: only check bailout once every 2 iterations. 
Once we bailed out we calculate the exact iteration in which it would have happened if needed.

e555119c73 mandelbrot: correct and simplify the formula used in NORMALIZED_ITERATION_COUNT 
Use log(sqrt(mb->bailout)) instead of log(mb->bailout) because mb->bailout represent
the bailout radius squared, and then simplify the two sqrt().
This is also slightly faster.
