Indeed, he even opened a dedicated website (http://bohoomil.com) but I
can't find an e-mail address to include him in this discussion... I
can't speak of him and his interest but I can make these patches public
to anyone with a desire for them.
Regarding the "right way", I agree that environment variables are to be
avoided but maybe not completely i.e. allowing just one to select from
the various built-in sets of settings and/or pointing to a user specific
custom settings file. I'm not familiar with the FT_Property_* API but
these settings (in the struct below) are quite many, lots of work to
pass them through function calls...
