A. What I thought was going on with family seemily being used
differently when paper was 'special'.
Now with some gentle prodding, I see that I was confusing two
different plots I was working on. Some swapping back into memory
hadn't finished on Monday morning when I made my observation. All

Yesterday, I knew considerably less about the difference between EPS
and regular PostScript (and most of that was misconception), so I was
unaware how simple the distinction was. Constrained by that
ignorance, I couldn't think of a way of showing more clearly what I
was on about.
Thanks Brian for your patience in helping me sort that out.
I have a small question about that difference:
Am I correct now in thinking that apart from the first line of a
single page graphic file (with current versions) reading
the only substantial differences between an EPS and a PS file are the
positioning of the origin of the bounding box at 0, 0 and the removal
of page orientation information?
