rotateVector

Rotates the given Vector3 by this quaternion.

This quaternion (this) should be a unit quaternion to represent a pure rotation. If this quaternion is not normalized, the transformation will also include scaling. The rotation is applied using the formula derived from v' = q * v * conjugate(q), often implemented efficiently as v_rotated = v + 2w * (u × v) + 2 * (u × (u × v)), where q = (u, w) (u is the vector part, w is the scalar part) and v is the vector.
