SWFDisplayItem->setRatio

Description

swfdisplayitem->setratio() sets the object's ratio to ratio. Obviously only useful for morphs.

The object may be a swfshape(), a swfbutton(), a swftext() or a swfsprite() object. It must have been added using the swfmovie->add().

This simple example will morph nicely three concentric circles.
