Changes the scale for the objects suceeding the scale object. This enables you to use, for example "mm," to describe the location of objects. Layers of graphics are rendered in z-order. The lowest z-order layer is painted first, and the highest z-order layer is painted last. Consequently, the lower z-order layers are conceived of as "farther" from the human viewer of a screen (or printed page). And the higher z-order layers are "closer" to the human viewer.
