We are working on the other two (though for depth clip disable I'm not
sure wrt differences to d3d10) so that would fit well. Maybe better to
stick to 3.1 until that has landed however (I'd be happy to lie about
seamless filtering, which probably if not supported any app would just
ignore anyway, but advertizing depth clip disable and then ignoring it
could probably give unexpected results).
