The Normal property of the Rotation struct provides a normalized version of the rotation. Normalizing a rotation involves dividing each component of the rotation by its length, ensuring that the rotation maintains a unit length. This is useful for maintaining the integrity of rotational calculations, as it prevents the accumulation of errors that can occur with non-normalized rotations.

To use the Normal property, simply access it from an instance of the Rotation struct. This will return a new Rotation instance that is the normalized version of the original rotation.
