It's good to know that when you do "$i->scaleTo(0,0)", it doesn't output an "empty object" ( nothing... ) on the screen, but the object with its original dimensions.

swfdisplayitem::scaleto() scales the current object to

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

after a shape etc. has been added, the refence to the DisplayItem is returned:
$displayItem = $sprite->add($shape);
$displayItem->scaleTo(0.1,0.1);
the above scales it to 0.1 of whatever its original size was
