     swfdisplayitem->setdepth() sets the object's
     z-order to depth. Depth defaults to the 
     order in which instances are created (by adding a shape/text to 
     a movie)- newer ones are on top of older ones. If two objects are 
     given the same depth, only the later-defined one can be moved. 
    
     The object may be a swfshape(), a 
     swfbutton(), a swftext() or a 
     swfsprite() object. It must have been added using
     the swfmovie->add().
