They're just an expedient for bootstrapping the use of the new awScene. There's not much point in making them private and giving them accessors, since they'll be gone when awScene is multithreaded.
Note, in the mean time, that our sense of dirtiness here is 'local'. Having dirty children doth not a dirty parent make.

| void setMaintainSceneHierarchy | ( | bool | maintain, |

The node is flagged to maintain hierarchy below it as coming from the scene, or coming from the imported file.
If a node is flagged as "do not maintain scene hierarchy", all of its descendents would have to be marked as such as well. If it's marked as "do maintain scene hierarchy", all of its ancestors need to be marked as such as well. This will be done automatically for you, unless you use the non-default value for the propagate flag. Note that setting the correct flag value is not automatic for the insertParent/insertChild/removeParent/removeChild operations. Methods "isMaintainSceneHierarchyFlagConsistent" and "fixMaintainSceneHierarchy" may come in handy for detecting and fixing any problems.
| bool getMaintainSceneHierarchy | ( | ) | const |
| bool isMaintainSceneHierarchyFlagConsistent | ( | ) | const |
| void fixMaintainSceneHierarchy | ( | ) |
| virtual bool needToMaintainSceneHierarchy | ( | ) | const [virtual] |
Look at the children and parents, and let us know if this node should be marked as "maintain" or not.
Return true if we really, really need that flag set. The "set...Check" behaves as the "set..." above if maintain is false. If maintain is true, it consults the "needTo..." to decide if it should set it or not. In the process, it may fix up the parents as well.
Reimplemented in Import, and LodCollapse.
