Having a look at how this is used in JS (see
https://developer.mozilla.org/en/DOM/NodeFilter) it seems clear we
just failed to properly bind the NodeFilter functionality. So I think
the answer at the moment is "you probably cannot use it". File a bug
about it and we can try to figure out how to fix it.
