I agree. Feel free to add that (and please mention face remapping, as I believe it is the only reason why the buffer, as opposed to the frame, could be relevant). > BTW, why does the Elisp manual say that it does "mostly provide > compatibility with old versions of Emacs"? AFAIU, it only says so about the set-face-FOO functions, which doesn't include face-font. > But we also should mention (and I still think `font-info' is the better > place for that) what happens when the current buffer has rescaled text > but is not displayed on the selected frame (or the frame denoted by the > argument of `font-info').

In face-remap.el, and then in xfaces.c (search for face_remapping in the latter). Assuming I understand correctly what is it that confused you.
