    This is more horrible than I had realized
    
    Due to tragic misunderstandings at the birth of ATK, AtkUtil
    can't actually be properly derived. Instead, each implementation
    has to poke its vfuncs directly into the AtkUtilClass struct.
    
    So painful to have shipped this stuff for 10 years...
