PDF's are fundamentally a VECTOR format. A vector
format designed around
typography where the most natural unit since long before computers has been
the point (=1/72 inch).
Technically, 100/7227 inch, which is to say, there are 72.27 points per inch
in typography prior to the creation of the Macintosh. (I don't believe that
Postscript originally used a 1/72 measure, and TeX certainly didn't, so I can't
just say "non-computerized typography".)
If you think *this* mailing list goes off-topic from time to time, you should
check out the Letpress mailing list, for metal type and ink folks.
