The ExclusionPolygon class stores the polygon's edges in an interval tree implementation called ExclusionPolygonEdgeTree. Each tree node stores a list of edges whose Y coordinates that are completely above, overlap, or below a "center" value. The length of the overlap list can be considerable and providing a pair of sorted views of the list would speed up the query methods in some cases.

The patch for https://bugs.webkit.org/show_bug.cgi?id=96811 replaced ExclusionPolygonEdgeTree with an instance of the existing PODIntervalTree template class.
