strange PK problem with a lilypond font

[Werner LEMBERG]

[CVS 2002-08-18 09:13]

There is a serious bug in the fetaXX fonts: The metrics are
resolution-dependent!  As a consequence, feta16.600pk anda
feta16.1800pk and its tfm files, to take an example, have different
checksums.

A diff on the tfm files (using tftopl) starts like this:

It looks like an epsilon quantity being added or subtracted
somewhere...
