gnome-icon-theme version 2 with gtk+3

Hi all,

I don't know for sure, and I don't want to speculate, if gnome-icon-theme version 2 is only supported for gtk+(2).

More exactly if I have gtk+3, will it work ok with gnome-icon-theme version 2?

And more question, is gnome-icon-theme version 3 going to look ok on a system with gtk 2?

Regards.
