A font-extend value of less than 1.0 would actually compress the glyphs, of course. And negative values ought to reflect the glyphs and reverse the text direction, so that <span style="font-extend: -1.0">mirror writing</span> becomes easy to express.

Well, no. It would look like rtl text in a mirror. With the glyphs backwards, and everything.
