Rats.

The metrics according to Pango appear to be in 0.1pt increments.  If we
are talking about PostScript/TeX point confusion, 42pt are 41.84bp, so
that would be _just_ short of 41.9bp after rounding.  I would not rule
it out as a source of the problem (particularly if Pango has to round to
get into its 0.1pt scale, and back again), but I am somewhat sceptical
nevertheless.

The main question is likely whether we now get consistent results from
LilyPond: Kieren reported inconsistent sizes depending on how the
absolute font size was arrived at.
