Vanilla YSFLIGHT only checks that the apparent radius of an object (screen size) is >=1 prior to drawing it.
Originally, we enhanced this check to also require that the object is in-front of the camera.
This check is further enhanced to also check that the object is within the camera's field of view. Aircraft are also culled now.
