79  - Should the child vobscene define the number of coordsys  - Should the child vobscene define the number of coordsys
80    in the beginning to replace with coordsys from the parent?    in the beginning to replace with coordsys from the parent?
81    
82    - What about coordinate system 0? Should it be special in the child
83      and always correspond to cs 0 of the parent (i.e. unit transformation)?
84      This is made problematic by the twim roles of coordinate system 0:
85      on the one hand, it's the "root" coordinate system,
86      on the other hand, it's the "no transofrmation" coordinate system.
87    
88        RESOLVED: It should be special. However, we should start a new
89        convention: coordinate system **1** is the "root" coordinate system,
90        and **0** remains the "identity" coordinate system.
