Firebug decompiles the document object. So it starts with
window.documentElement and walks all of the childNodes and their
children recursively.  Well actually it doesn't do that ;-). It starts
with the currently selected element and walks it parents to the root
and the children, rendering one branch from root to leaf. Then if you
visit siblings it remembers the branches it has already rendered.
