Detailed Description

Base scene-graph class.

See scene_graph.hh.

Functionality of this base class:

• creates and caches "branch nodes" for state-sorting according to NodeSort
• can attach low-level nodes
• can attach higher-level Objects
• automatically detaches Objects when DestroyObject event is broadcast
