I think I can get something acceptable with `font-get`. indeed,
thank you.

Hmmm... based on my naive understanding of these things I think we
should be able to convert a font-entity into a font-object by calling
the `open_font` method of the font driver. Of course, this can fail and
it's not free so it's not a good option.
Similarly it should be possible to compare font-object and font-entities
but ignoring the last few fields. Or offer a function to convert
a font-object or font-entity into a font-spec (similarly by dropping
the last few fields).
Also maybe we can use the FONT_OBJLIST_INDEX field of font-entities to
provide a "font-instance-of" test to see if a font-object is an instance
of a given font-entity.
