  Holds point data. Is usually handled internally by the library and serves only as detailed information to the end-user.



  Parameters:

  - `:x` [`t:non_neg_integer/0`]: first point coordinate;

  - `:y` [`t:non_neg_integer/0`]: first point coordinate;

  - `:z` [`t:non_neg_integer/0`]: first point coordinate (used only in Jacobian coordinates);
