Gnome themes for gtk3 ?

[Martin Husemann <martin%duskware.de@localhost>]

Now that more and more things are moving to gtk3, it seems I am missing
something like x11/gnome-themes (which is for gtk2).

I have a "minimal" installation, nothing gnome-ish, but Xfce4 and Firefox
are using gtk3, and it seems the few available themes on my machine are
buggy.

Do we need a separate x11/gnome3-themes and have xfce4 depend on it?
