By default, this method will call ``_reference_clone`` (see ``_reference``). Args: pdf_dest: Target to clone to. force_duplicate: By default, if the object has already been cloned and referenced, the copy will be returned; when ``True``, a new copy will be created. (Default value = ``False``) ignore_fields: List/tuple of field names (for dictionaries) that will be ignored during cloning (applies to children duplication as well). If fields are to be considered for a limited number of levels, you have to add it as integer, for example ``[1,"/B","/TOTO"]`` means that ``"/B"`` will be ignored at the first level only but ``"/TOTO"`` on all levels.
