/** \brief
|
|
* Validates that the result of an overlay operation is
|
|
* geometrically correct within a determined tolerance.
|
|
*
|
|
* 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.
|
|
*
|
|
* This algorithm is only useful where the inputs are polygonal.
|
|
*
|
|
* 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.)
