"Update Marble French documentation screenshots (20). In a default KDE installation, use KSnapshot to do all the screenshots to match the English ones from https://projects.kde.org/projects/kde/kdeedu/marble/repository/revisions/master/show/doc. Instructions about screenshots: http://l10n.kde.org/docs/screenshots.php. Some screenshots are existing but in an outdated window decoration here http://websvn.kde.org/trunk/l10n-kde4/fr/docs/kdeedu/marble/ and they all need to be redone.
Expected results: The 20 screenshots in French interface are up-to-date with current Marble interface and current KDE default style and default window decoration.
Prerequisites: Marble installed with French interface, KSnapshot, Marble knowledge"
