this seems to imply that there are indeed PFR0 fonts with kerning info.

Thanks a lot for these explanations. I wasn't able to find this
information in the documentation that comes with the sources. I think
it should be added there.

if I'd have a PFR font with enough kerning information I could try to
make it work for fonts that have multiple type 4 extra item. At the
moment subsequent extra items with kerning info are ignored (see
pfrload.c line 517).
