That would be interesting. When I was working on selections I found I
wasn't even able to come up with an idea that would work. Unless scanning
all scanlines of an image and doing something clever when the difference between
the previous and the current pixel passes a threshold is what would work,
after all... The gimp does something frightfully clever with segments -- I
never grasped that at all.
