Upgrading to Gtk 3.22 #1
Description
I tried update gir-files with ubuntu's latest (like http://packages.ubuntu.com/zesty/amd64/libgtk-3-dev).
Examples with feature gtk_3_18 build fine, but I can't build version depends on gtk/v3_18 as no package with these features published.
So I starting make PRs for prepare these packages, not sure that it time for publish new crates (maybe we need solve other needed problem).
@GuillaumeGomez, how you think?
