    <thetext>The ExclusionPolygon class stores the polygon&apos;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 &quot;center&quot; value.  The above and below lists are recursively subdivided until no above/below edges remain.  The class should provide a minSubtreeSize parameter that stops the recursive subdivision when only a small number of edges remain.</thetext>

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