This is NOT the way to do it, unfortunately.  Everything will be scaled:
linewidth, font sizes, etc.
Instead, you have to do something like

	/cm {UNIT mul} def 	% or bind def perhaps?

where UNIT is the appropriate conversion factor.  And then you have to write
"cm" after every measuring value :-(  Thanks to Adobe who apparently didn't
realise that postscript brought printing from the typesetting industry to
the office, where people use ordinary rulers.

P.S.
I am so confused by the current discussion, that I don't dare to suggest the
value of this conversion factor.  Can someone post it, please?
