    container: Turn assert into return_if_fail()
    
    There's no reason to insta-crash when something goes wrong. Just don't
    do anything stupid.
    
    Also, remove the SPCIAL_CONTAINER() exception. Every case where special
    containers needed this, it is wrong and made containers draw children
    multiple times.
