  Both Vector classes have a value named ``epsilon`` that defaults to ``1e-6``.
  This value acts as a numerical margin in various methods to account for floating point
  arithmetic errors. Specifically, ``epsilon`` is used in the following places:

     * comparing Vectors (``==`` and ``!=``)
     * the ``is_normalized`` method (if the square of the length is within ``epsilon`` of 1, it's normalized)
     * slerping (a Vector with a length of ``<epsilon`` is considered a zero vector, and can't slerp with that)
     * reflection (can't reflect over the zero vector)
     * projection (can't project onto the zero vector)
     * rotation (only used when rotating by a multiple of 90 degrees)

  While it's possible to change ``epsilon`` for a specific instance of a Vector, all the other Vectors
  will retain the default value. Changing ``epsilon`` on a specific instance however could lead to some
  asymmetric behavior where symmetry would be expected, such as

  ::

     u = pygame.Vector2(0, 1)
     v = pygame.Vector2(0, 1.2)
     u.epsilon = 0.5 # don't set it nearly this large

     print(u == v) # >> True
     print(v == u) # >> False

  You'll probably never have to change ``epsilon`` from the default value, but in rare situations you might
  find that either the margin is too large or too small, in which case changing ``epsilon`` slightly 
  might help you out.

  | :sl:`Creates a Vector3(x, y, z) or sets x, y and z from a spherical coordinates 3-tuple.`
  | :sg:`Vector3.from_spherical((r, theta, phi)) -> Vector3`
  | :sg:`Vector3().from_spherical((r, theta, phi)) -> None`

  If used from the class creates a Vector3(x, y, z), else sets x, y, and z.
  The values of x, y, and z are from a tuple ``(r, theta, phi)`` where r is the radial
  distance, theta is the inclination angle and phi is the azimuthal angle.

  .. ## Vector3.from_spherical ##

  | :sl:`projects a vector onto another.`
  | :sg:`project(Vector3) -> Vector3`

  Returns the projected vector. This is useful for collision detection in finding the components in a certain direction (e.g. in direction of the wall). 
  For a more detailed explanation see `Wikipedia <https://en.wikipedia.org/wiki/Vector_projection>`_.

  .. versionadded:: 2.0.2

  .. ## Vector3.project ##

  | :sl:`Returns a copy of itself.`
  | :sg:`copy() -> Vector3`

  Returns a new Vector3 having the same dimensions.

  **Experimental:** feature still in development available for testing and feedback. It may change.
  `Please leave clamp_magnitude feedback with authors <https://github.com/pygame/pygame/pull/2990>`_

  Returns a new copy of a vector with the magnitude clamped between 
  ``max_length`` and ``min_length``. If only one argument is passed, it is 
  taken to be the ``max_length``

  This function raises ``ValueError`` if ``min_length`` is greater than
  ``max_length``, or if either of these values are negative.

  **Experimental:** feature still in development available for testing and feedback. It may change.
  `Please leave clamp_magnitude_ip feedback with authors <https://github.com/pygame/pygame/pull/2990>`_

  Clamps the vector's magnitude between ``max_length`` and ``min_length``.
  If only one argument is passed, it is taken to be the ``max_length``

  This function raises ``ValueError`` if ``min_length`` is greater than
  ``max_length``, or if either of these values are negative.

  Sets coordinates x, y, and z in place.
