An additional thing i've done [already long ago but time flies by] is to
patch some of hobbies modules so that when needed this method is used
instead of the kind of pseudo typesetting that takes place in the diagram
modules. Interesting code in itself, this code of hobby, since it assembles
numbers from snippets of btex/etex pictues, but unfortunately it invokes
too many additional runs.
