OK. In that case you mean the 65536 needs to removed from the other 3
coords. That is I want:

 else
  {
    fprintf(out, "/FontBBox [%ld %ld %ld %ld] def\n",
                 ti->ttface->bbox->xMin,
                 ti->ttface->bbox->yMin,
                 ti->ttface->bbox->xMax,
                 ti->ttface->bbox->yMax);
  }

Correct?

That's fine :)  We haven't heard from him for a long time now, so I
wanted to say something encouraging in his favour.

I'll be able to apply your patch in the next day or two, but I'm not
sure of a good way to test it.  Do you know of a reliable way to force
firefox, say, (which prints to Xprint) to select a type 3 font via
freetype, in such a way that ti->ttheader remains undefined, where ti is
a struct ft2info (ttheader is read from FT_Get_Sfnt_Table) ?  Well I
guess I can explicitly set the ttheader to null for testing purposes,
but I'm not sure about invoking the type 3 font.
