cs2d max has a new rendering/drawing order for floors/walls/players/sprites/images. depending on the usage of env_sprite und env_image some old maps might look messed up due to the new rendering order of cs2d max. (tiles overlapping sprites/images etc.)

you only have to use this entity if you want to change the rendering order to the old rendering order of 0.1.0.4. ignore this entity if you don't have problems with the rendering order of sprites/images.
