16 Multiplies the point (x, y, z) by the quaternion q, storing the result
17 in (*xout, *yout, *zout). This is quite a bit slower than
18 apply_matrix_f(), so only use it to translate a few points. If you have
19 many points, it is much more efficient to call quat_to_matrix() and
20 then use apply_matrix_f().
