    clutter-backend-x11: Don't set the font-dpi computed on X11 parameters
    
    We already correctly set the font-dpi based on user settings in
    MetaSettings at each user change and as part of backend initialization,
    so there's no point to set it also during x11 backend post-parsing and
    using X11 values, as this may happen at later point and lead to a wrong
    clutter font DPI value.
