It's 4.  Looking up and down is not accomplished by rotation.  It is
accomplished by a clever hack, which gives the impression of looking up and
down.  All they do when you look up is start drawing at a greater angle, and
stop drawing at lesser angle.  It's difficult to explain, but you can tell
because when you look up as far as it will let you, everything becomes
distorted.  Also, no matter how high your head is pointed, the walls are always
vertical.  If it were rotating the head, then the wall at the bottom of the
screen would be closer than the wall at the top of the screen when you look up.
