LUCENE-9152: Improve line intersection detection for polygons (#1187)
> Improve line intersections from polygons
> ----------------------------------------
>
> Key: LUCENE-9152
> URL: https://issues.apache.org/jira/browse/LUCENE-9152
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Ignacio Vera
> Priority: Minor
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Currently we always check triangle intersection in polygons without considering the boundary. This is not totally right as it might miss an intersection if a polygon and a triangle are touching each other.
>
> The proposal is the following:
> * if there is no points of the triangle inside the polygon, then consider the boundary
> * If all points are inside the polygon, then do not consider the boundary.
