gnome-desktop/gnome-desktop-fate300461-desktop-gettext.patch

Add support of gettext for desktop entry files.

We only support this for the following keys: Name, GenericName, Comment. We
don't support all keys because it can create issues for the Icon key (which is
localizable -- which can result in a broken icon).

Translations that are present in the desktop entry take precedence over
translations via gettext. If we don't do this, then user modifications won't
appear since they will have lower precedence.
