And if *I* were a beginner, I would expect that you could specify sizes
for plot symbols in physical pixel units if you wanted, and that at
least a given symbol of a given size would occupy a fixed number of
pixels from one platform to the next. I would sure be one disappointed
beginner, though, especially if I had learned from some higher power how
to summon the powers of "device,copy" to erase areas of windows for
dynamic re-drawing.
