Ignacio Vera updated LUCENE-8071:
---------------------------------
    Attachment: testPointsWithIn.patch

Thanks for committing [~karl wright],

Fair to say that the shape only supports planets which are slightly elongated 
like WGS84 (~abs(flattening)<0.1). 

I attach the test I am using to check the shape in case you think it is useful. 
I will move this shape to the spatial4j wrapper if it is ok with you.

> Hi [[email protected]],
> There is still a situation when the test can fail. It happens when the planet 
> model is a SPHERE and the radius is slightly lower than PI. The circle is 
> created with two sectors but the circle plane is too big and the shape is 
> bogus.
> I will attach a test and a proposed solution. (I hope this is the last issue 
> of this saga)
