Change corner handling.
ray_def should now deal with hitting corners gracefully, though the
raycasting will still discard such rays. If a ray hits a corner
between two diamonds, it will stay there, and calling ray_def::pos
will arbitrarily give one of the squares -- this is not optimal,
but these rays shouldn't usually show up anyway.
