(integer) The manual
documents it as returning a table, which meant I didn't know what to do having
detected a duplicate, but I found this text in the changelog which led
to the above.
* The 'define_font' callback interface has changed a little.
It is now:
retval = function (name,size,fontid)
where fontid is the internal font number of the font that
is currently being defined, and retval can be either a table
(as before) or a different, previously defined fontid. This is
useful if a previous definition can be reused instead of
creating a whole new font structure.
done
it could be the id of an already defined font (e.g. with font.define)
