This commit contains a number of performance improvements for the BGE in the Scenegraph (parent relation between objects in the scene) and view frustrum culling. The scenegraph improvement consists in avoiding position update if the object has not moved since last update and the removal of redundant updates and synchronization with the physics engine. The view frustrum culling improvement consists in using the DBVT broadphase facility of Bullet to build a tree of graphical objects in the scene. The elements of the tree are Aabb boxes (Aligned Axis Bounding Boxes) enclosing the objects. This provides good precision in closed and opened scenes. This new culling system is enabled by default but just in case, it can be disabled with a button in the World settings. There is no do_version in this commit but it will be added before the 2.49 release. For now you must manually enable the DBVT culling option in World settings when you open an old file. The above improvements speed up scenegraph and culling up to 5x. However, this performance improvement is only visible when you have hundreds or thousands of objects. The main interest of the DBVT tree is to allow easy occlusion culling and automatic LOD system. This will be the object of further improvements.
