0028 // Class Description:
0029 //
0030 // Class managing the per-thread state of the geometry, spanning those
0031 // which have a per-thread state and their dependents.
0032 // In particular it:
0033 //       - owns the arrays that implement 'split' classes
0034 //       - owns classes/objects which are owned by the split classes.
0035 // The classes/objects affected are:
0036 //       - 'split' classes part of its state is per-thread,
0037 //       - per-thread objects, in particular those which are owned
0038 //         by the split classes.
0039 // Goal: Take ownership and control of per-thread state of
0040 //       classes to work with multi-threading.
