Depends on how you write the HTMLFormatter and SVGFormatter. We can probably 
write a general base class that handles looking for _html_() methods and to 
allow registration of functions for types that cannot be modified. I've broken 
out the deferred type-dispatching I use in our pretty.py before; I'll try to 
find it.
