>> 1 point = 1/72 inch.  (ie, 72 point type is 1 inch tall)

Actually, a point is 1/72.27 inches according to the pros.  Only PostScript
insists on thinking that a point is 1/72 inches.  I've wondered if a TeX
ruler that is made by dvips ends up wrong because of this?  (TeX uses the
correct value.)  I've never tested it.
