    clutter: Reuse GTK+'s RTL/LTR handling
    
    Commit a4fb7ef5a3e dropped translations of our internal cogl/clutter
    forks, which broke the local-based text direction support. Instead
    of bringing back translations just for this purpose, we can re-use
    GTK's translations which use the same technique.
