SWFSprite->add() — Adds an object to a sprite
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.
swfsprite->add() adds a swfshape(), a swfbutton(), a swftext(), a swfaction() or a swfsprite() object.
For displayable types (swfshape(), swfbutton(), swftext(), swfaction() or swfsprite()), this returns a handle to the object in a display list.
No value is returned.
