[Papervision3D] PaperVision3D + APE experiment test

Oh! just for reference in case someone else sees this, I just had to change
the line:

shadowPlanes[s].copyPosition(vector);

To

shadowPlanes[s].position(vector);

copyPosition() was expecting a Matrix3D or a DisplayObject3D;

*from DisplayObject3D:**
public function copyPosition( reference:* ):void
        {
            var trans  :Matrix3D = this.transform;
            var matrix :Matrix3D = (reference is DisplayObject3D)?
reference.transform : reference;

            trans.n14 = matrix.n14;
            trans.n24 = matrix.n24;
            trans.n34 = matrix.n34;
        }*
