Well, if there was some way of getting the images marked up as (for
example) width='40em', then we can let the browser do the scaling (which
would be way cool - it mean the graphics would shrink and grow with
CTRL-+/CTRL-minus).  

Can you specify an equation width in the source?  Would that be too much
work?
