Submitted by Laurent Pointecouteau

Actually, I'm not 100% sure that will be a definitive enhancement, but I'm asking anyway.
The dark variant feature (see http://developer.gnome.org/gtk3/3.2/GtkSettings.html#GtkSettings--gtk-application-prefer-dark-theme) is used by GTK3 apps such as Eye of GNOME, Totem (and his future successor Videos), and will be in the SHotwell viewer in the near future, according to their bugtracker. Is this feature relevant for a video editing app such as PiTiVi ? Maybe it is still bit early to ask for it...
