If anyone is interested, the plan is to replace the current t1 hinting module
with one which uses the autofit module, providing the hints from the font
instead of letting autofit guess them itself.

It hasn’t gotten done because autofit does a good job on its own (especially in
its vertical-only mode, named light autohinting in the API) and most t1/cff
fonts these days seem to be autohinted anyway.

FT_LOAD_TARGET_LIGHT|FT_LOAD_FORCE_AUTOHINT may even be a better choice for gs
than FT_LOAD_NO_HINTING, for type1 and cff.

Also, with regard to 11009, does a_fapi_font->is_type1 match cff fonts, too?  I
doubt ft’s cff hinting is any different than its type1 hinting....
