Anyone have this changeset around? Looks like it was not posted to the mailing

In Squeakland and Etoys, characters are not morphs :-(. Small morphs like 
character glyphs pose interesting challenges in programming. Just storing 
polylines, curves and textures is not enough. Without proportions and shape 
hints, aesthetics will be difficult to preserve across transformations.

Has anyone tried to the create the equivalent of Don Knuth's METAFONT in
