    icon: provide a symbolic variant of the app icon
    
    Since 3.16 the high contrast accessible theme is
    covered by the recolorable symbolic variant of the app icon.
    
    The symbolic size has been introduced to hicolor to cope with
    the nominal size of 16x16 rather than the backward compatible
    128x128.
