And text that is blue and underlined causes a click-reflex :)

I would also be interested in support for underline, overline, 
strike-through, italic and bold fonts, (for all texts, not just HTML 
labels) basically because Graph::Easy supports these (as does CSS after 
which it is modeled) and currently it cannot output these things in 
graphviz.
