Karl Wright commented on LUCENE-7430:
-------------------------------------
The north rectangle that is misbehaving is a narrow, very tiny rectangle with
one point at the north pole and the other two points not far different from
that. The point is coming up as being not within the bounds but as being
within the shape. But this applies only to the quantized point; the
unquantized point is fine.
So in this case it would initially appear that we have a test problem.
We generally accept that there are some effects of quantization; once a point
is quantized it potentially leaves the exact surface of the world and can
therefore wind up being outside of a shape's bounds. That appears to be the
situation here. The only question is: what to do about it, without making the
test useless?
