My self-compiled LilyPond produces the 'other' glyph version (i.e.,
not `two.png`).

Attached you can find the METAFONT proof sheet for glyph 'two'.  Since
METAFONT is not involved in our font production chain (METAPOST is),
it is a good indicator that the 'other' glyph version is the right
one.

BTW, a PFB font without FontForge postprocessing can be created with

```
FONTFORGE=foo perl ../scripts/build/mf2pt1.pl --rounding=0.0001 
feta-alphabet20.mf
```

For glyph 'two', the postprocessing effects are very subtle; FontForge
adds points at all extrema and reduces the number of points to get
smaller fonts (ensuring that the outline changes are less than a
certain threshold).  I suspect that this last step doesn't work
correctly.
