Great work! One documentation bug:
Now it is time to discuss units. \MP\ uses as basic unit PostScript points which correspond to $1/72$ inch. We use them in \FMP, too. |hspace 8| defines a horizontal distance of $1/9$ inch or approximately $2.82$ mm.
This contradicts the table that immediately follows, in which it is evident that a unit of '1' is one printer's point, 1/72.27 of an inch; the Postscript points are called 'bp'. Which is correct?
Thanks for spotting this mistake. FMPPicture.lhs has the answer:
mm, pt, dd, bp, cm, pc, cc, inch:: Numeric mm = 2.83464 pt = 0.99626 dd = 1.06601 bp = 1 cm = 28.34645 pc = 11.95517 cc = 12.79213 inch = 72
which a quick test also ensures. So the table is mistaken, we will fix it shortly. Cheers: Feri.
