This is somewhat tricky. Actually I had a mechanism for that but I 
discarded the code. However there will be a feature like that some day 
as it needs a rather tight integration in the core of context's font 
handling. (btw, there is a feature for type 1 fonts that adds 'missing' 
kerns based on shape codes).
