Added occlusion culling capability in the BGE. More info: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.49/Game_Engine#BGE_Scenegraph_improvement MSVC, scons, cmake, Makefile updated. Other minor performance improvements: - The rasterizer was computing the openGL model matrix of the objects too many times - DBVT view frustrum culling was not properly culling behind the near plane: Large objects behind the camera were sent to the GPU - Remove all references to mesh split/join feature as it is not yet functional
