    x11: Stop reordering visuals
    
    The old code was ordering visuals by depth, but considering that these
    days we either use the default visual or a 32bit RGBA visual, that
    reordering does not have an effect anymore.
    
    In theory, the only effect is that the GLX Visual selection might select
    a different replacement Visual when it checks for improved GL Visuals, but
    even there I can't come up with a case where that matters, because
    again, the visuals are only reordered by depth and we want to keep the
    depth.
    
    In any case, make this a separate commit so bisecting can find this
    problem if it ever shows up.
