Ahhh! I use ghostview ('gv') for viewing PS files, and (a) you
can set an option for antialising (which gives much better visual
resolution of curved boundaries); (b) you can change the zoom
factor on the fly; (c) if you really want to see what's going
on at a particular place you can outline it with the mouse and
zoom it up.

Well, it's good that the problem got solved!

Best wishes,
Ted.
