I got the following bug report...

--------------------
PfaEdit puts in ghost hints to align the bottom of curves which are in
within blue zones. But this appears not to work with freetype.

To me this seems like a reasonable thing for PfaEdit to do, but I may be
wrong. David, or Werner is this my bug or yours?
