The Scale alteration will cause the sprite to incrementally change size. You can
scale on the x or y axis or both.
FireFox may fail to launch completion events if sprite
size reaches 0.0. Therefore, also set a minimum size of 0.01 or something
smaller if necessary.

- specify a routine to run when the scaling is complete.
- a scale rate per second. Use a negative value to shrink and a positive value to grow
- specify in which direction to scale the sprite. If type is not specified the scaling is performed both ways.
- the value at which the scaling should end. Be sure this number makes sense with
respect to the initial size of the sprite and the rate being negative or positive.
