 A quaternion is defined as the quotient of two directed lines in a
 three-dimensional space or equivalently as the quotient of two Euclidean
 vectors (https://en.wikipedia.org/wiki/Quaternion).

 Quaternions are often used in calculations involving three-dimensional
 rotations (https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation),
 as they provide greater mathematical robustness by avoiding the gimbal lock
 problems that can be encountered when using Euler angles
 (https://en.wikipedia.org/wiki/Gimbal_lock).

 Quaternions are generally represented in this form:

     w + xi + yj + zk

 where x, y, z, and w are real numbers, and i, j, and k are three imaginary
 numbers.

 Our naming choice `(x, y, z, w)` comes from the desire to avoid confusion for
 those interested in the geometric properties of the quaternion in the 3D
 Cartesian space. Other texts often use alternative names or subscripts, such
 as `(a, b, c, d)`, `(1, i, j, k)`, or `(0, 1, 2, 3)`, which are perhaps
 better suited for mathematical interpretations.

 To avoid any confusion, as well as to maintain compatibility with a large
 number of software libraries, the quaternions represented using the protocol
 buffer below *must* follow the Hamilton convention, which defines `ij = k`
 (i.e. a right-handed algebra), and therefore:

     i^2 = j^2 = k^2 = ijk = −1
     ij = −ji = k
     jk = −kj = i
     ki = −ik = j

 Please DO NOT use this to represent quaternions that follow the JPL
 convention, or any of the other quaternion flavors out there.

 Definitions:

   - Quaternion norm (or magnitude): `sqrt(x^2 + y^2 + z^2 + w^2)`.
   - Unit (or normalized) quaternion: a quaternion whose norm is 1.
   - Pure quaternion: a quaternion whose scalar component (`w`) is 0.
   - Rotation quaternion: a unit quaternion used to represent rotation.
   - Orientation quaternion: a unit quaternion used to represent orientation.

 A quaternion can be normalized by dividing it by its norm. The resulting
 quaternion maintains the same direction, but has a norm of 1, i.e. it moves
 on the unit sphere. This is generally necessary for rotation and orientation
 quaternions, to avoid rounding errors:
 https://en.wikipedia.org/wiki/Rotation_formalisms_in_three_dimensions

 Note that `(x, y, z, w)` and `(-x, -y, -z, -w)` represent the same rotation,
 but normalization would be even more useful, e.g. for comparison purposes, if
 it would produce a unique representation. It is thus recommended that `w` be
 kept positive, which can be achieved by changing all the signs when `w` is
 negative.
