The Geom extrema API's are not finding extrema/intersections for
very large circle/line.
Create a circle with centre 0 0 0 and radius 50000.
create a line passing ( 0 0 -50500, 0 0 50500) thru this circle.
Finding extrema gives only one solution ( the farthest point).
For small circles ( of radius 100) , the API gives 4 solutions.
Why not for the earlier case.
