<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Validates that the result of an overlay operation is geometrically correct within a determined tolerance. </p>
<p>Uses fuzzy point location to find points which are definitely in either the interior or exterior of the result geometry, and compares these results with the expected ones.</p>
<p>This algorithm is only useful where the inputs are polygonal.</p>
<p>This is a heuristic test, and may return false positive results (I.e. it may fail to detect an invalid result.) It should never return a false negative result, however (I.e. it should never report a valid result as invalid.)</p>
