28 // Class Description:
29 //
30 // Class managing the per-thread state of the geometry, spanning those
31 // which have a per-thread state and their dependents.
32 // In particular it:
33 // - owns the arrays that implement 'split' classes
34 // - owns classes/objects which are owned by the split classes.
35 // The classes/objects affected are:
36 // - 'split' classes part of its state is per-thread,
37 // - per-thread objects, in particular those which are owned
38 // by the split classes.
39 // Goal: Take ownership and control of per-thread state of
40 // classes to work with multi-threading.
