I had a different idea in mind. Instead of building geometric frameworks on top 
of morphs, we could treat Morph as a box glyph associated with a shape 
definition (bitmap, graphemes, emoticons, svg element, LaTeX code, postscript, 
metapost ...). A "edit" message (shift-click) to a morph will invoke a class-
specific editor to edit the definition. drawOn: would interpret this definition 
to render the glyph to a bitmap and cache it. The cache will be invalidated 
when definition is edited.
