   Or for that matter, should print events be fired in Opera when I
select text and press "V", which makes Opera read the selected text out
loud for me. Also, there the fact that if I'm printing a specific
selection of text, I may not need the document to be transformed at all.
In fact, the text I have selected may be contained entirely inside a
single text node, in which case print events can only serve to alter or
remove the text itself.
