Known Subclasses:
  - JacobiConformalSpherical

This is a conformal projection of a triaxial ellipsoid to a plane in which the `X` and `Y` grid lines are straight.

Ellipsoidal coordinates beta and omega are converted to Jacobi Conformal y respectively x separately. Jacobi's coordinates have been multiplied by `sqrt(a**2 - c**2) / (2 * b)` so that the customary results are returned in the case of an ellipsoid of revolution.
