Comment (by belg4mit):

 I understand your point, but that's still a form of iteration, simply over
 a continuously updated list rather than pixel indices (which does occur as
 well). Regardless, why couldn't the start cells be divided up among
 multiple threads? e.g; those on the top of the image for core0, and those
 on bottom for core1.
