Returns this quaternion with a magnitude of 1 (Read Only).
When normalized, a quaternion keeps the same orientation but its magnitude is 1.0.
Note that the current quaternion is unchanged and a new normalized quaternion is returned. If you
want to normalize the original quaternion, use the Normalize method instead.
If the quaternion is too small to be normalized Quaternion.identity will be returned.
