Jonathan Blandford is the real TreeView maintainer, I'm just a kind of
co-maintainer.

The original idea was to get it in GTK+ 2.2, but it got punted to GTK+
2.4. I guess I'll commit it once GTK+ 2.2 branches.

Rhythmbox (rhythmbox.org) is using the filter model with pretty big
treemodels. The filter model seems to hold pretty well. So I think it's
pretty stable. Of course bug reports are always welcome :)

Yeah, I only have a few (two or so) outstanding fixes which I will try
to commit soonish. Those aren't crucial fixes though.
