Documentation

A rather special geometric problem arising from fillets. Given a 2D point and a normal, find the ellipse that passes through the point with the normal that also passes through origin tangent to the X axis and is symmetric w.r.t. the Y axis.
Returns:
A 2D point, y component is vertical radius of ellipse, x component is horizontal radius.
