This fractal is an oversized thing consisting of three main
Mandeloids, the largest of which barely appears in the southwest corner
of the default screen."

If I zoom out some on the parent fractal I can see the largest mandeloid
fully. Can there images produced using the 
MandelbrotMix4 formula such that you could continue to zoom out and find
them in the largest possible field? Or is there a limit to how far out
they can occur?
