I had essentially never heard of this task.  I do not understand why
it would want to list distance at all.  A slice line passing across
the image but not through the reference pixel would clearly have dIST
starting at some larger number, going to some minimum, and then going
up again.  The X and Y values would be much better for telling where
things really are.  How about I change the task to put out X, Y, and
DIST in 3 columns instead of just DIST in 1 col?
