SWFMovie::add — Adds any type of data to a movie
�˺�����ʵ�����ġ��˺����ı��������Ƽ�������ĵ���������δ���� PHP �����汾��δ֪ͨ�ͱ��ġ�ʹ�ñ����������Ե� ��
Adds an SWF object instance
to the current movie.
For displayable types (shape, text, button, sprite), this returns an SWFDisplayItem, a handle to the object in a display list. Thus, you can add the same shape to a movie multiple times and get separate handles back for each separate instance.
