  That was is; it's fixed on the wiki.  Olivier can enjoy his line of
little skulls with the correct metrics ...

  By the way, I thought the test on size was wrong too [if (size < 0)
then size = (- 655.36) * size end] because, from reading the LuaTeX
reference, I assumed that a size of -1 meant an actual size of
design_size, thus defaulting to 10pt == 655360sp.  But after testing, it
seems that it's actually not the case and that that number has to be
divided by 1000.  Am I mystified or should the paragraph at the end of
page 50 of the manual be corrected?  I do remember having read something
about a factor 1000 in the past ... (like Metafont's mag parameter).
