Bug in vtkPointLocator::FindClosestInsertedPoint
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
In the special case, when the point locator is empty, i.e. no points have been inserted yet, the function vtkPointLocator::FindClosestInsertedPoint returns "0" instead of "-1".
"-1" means no closest point was found, and would be the correct return value.
