Re: Extent positioning attributes / model-view separation

Well, if you were careful to set up your text glyphs so that the "alpha" glyph was always reused when you see "\alpha" in the TeX buffer, it would be nearly the same. But AFAIK, if you (very naturally) scanned over the buffer for "\\\(alpha\|beta\|...\)", then did (make-glyph (match-string 1)), you would get a new glyph for each occurance of "\alpha". The idea here would be to make the glyph instantiator be an index into a font (normally simply a character) rather than a string. This way the glyphs for all occurances of "\alpha" would automatically be eq (in Emacs Lisp).
