I don't know.

No, the undocumented load_font function does not require GDOS
(it may not even work if you have GDOS).
It actually doesn't load fonts at all, it just registers with the VDI
a list of fonts that your application has loaded.
You can then use the regular VDI functions to select these fonts.
I supplied a routine to load .FED-format fonts, but that could
be rewritten to load other font formats.
