It's now this:
Second, the cache calls, only when needed, a client-provided function
to convert an @FTC_FaceID into a new @FT_Face object. The latter is
then completely managed by the cache, including its termination
through @FT_Done_Face. To monitor termination of face objects, the
finalizer callback in the `generic' field of the @FT_Face object can
be used, which might also be used to store the @FTC_FaceID of the
face.
Thanks for the feedback.
