.Only it doesn't do that--it *really* generates the starting image (of the whole
.set) in about 5 seconds.  Now this image is about 1/3 the size of the screen...

Meaning, about 1/9 the pixel area of the screen?  And (important!) how many
iterations?  The run time is proportional to number of pixels times
number of iterations per pixel, *not* to the area of complex plane covered.

.I could go home and run some benchmarks if you insist. :-)

No, that's ok, I apologize.  I'll run my own tests soon as I download it.
