    app: string which should be translated too.
    
    There is no reasons not to translate the "occurs" text which will be
    in the color names in palettes extracted from images. It indicates on
    how many pixels a given extracted color was occuring. We should also
    translate the full string (not just "occurs") since some language will
    have to reorder words, and may even use different bracket characters.
    So I also add a translator comment to make sure the translators get
    what the %s and %d stand for in this string.
