To tell you the truth, I don't know what that means.  "Text zoom" is
just one particular case of the use of faces to change the size of text.
So do you want the alternative function to only handle text-zoom
(i.e. remapping of the `default' face, so the face applies to
"everything"), or do you want it to handle the more general case where
every glyph might have different size?

If the former, than it'll just be another ad-hoc hack.
