Folders removed entirely: * //extern/recastnavigation * //intern/decklink * //intern/moto * //source/blender/editors/space_logic * //source/blenderplayer * //source/gameengine This includes DNA data and any reference to the BGE code in Blender itself. We are bumping the subversion. Pending tasks: * Tile/clamp code in image editor draw code. * Viewport drawing code (so much of this will go away because of BI removal that we can wait until then to remove this.
