150    So far, the only special CS has been coordinate system 0.
151    From now on, coordinate system **1** shall be the "root" coordinate system,
152    and **0** remains the "identity" coordinate system (representing
153    an identity transformation).
154    
155    The unit box of CS 1 is set to screen size, while the unit box
156    of CS 0 is (1,1).
