Translation of integrated title bar actions

[Reinout van Schouwen <reinouts gnome org>]

Hello all,

In Dutch, we have (close to) complete translations of both Mutter and
Gtk+. Window operations such as Minimize and Close are translated in the
respective po files in the 3.10 and master branches.

However, running with Mageia 4 beta (gtk+ 3.10.4, mutter 3.10.2) with
locate nl_NL here, the window actions in the context menu on windows
with integrated title bars, such as Web and Documents, are shown in
English.

I'm not sure where to translate these strings if not in either Mutter or
Gtk+. Can anyone help?

regards,
