    pango/shape.c: Use the former rounding code as needed
    
    The careful rounding code that was brought back as a result of commit
    d4356779 only had effect if we are using a backend that supported font
    hinting, so on other backends, use the former rounding code that was
    dropped in favor of the careful rounding code that unfortunately did not
    apply for all backends.
    
    Should fix #578.
