i would be happy to fix that (by adding you as developer), but squeaksource
today living its last days,
and does not persists project changes (including adding developer(s)),
means that every time SqS image reboot you will need to ask to be added
again and again.
Today, we placed all relevant Pharo VM sources on github (yes, including
all .st sources in form of FileTree)
and freetype plugin is one of them, and we're going to support it there.
Needless to say, that everyone is invited to contribute there.

font in that set..
Which is utterly ugly, i would say.
