// except that it interpolates the point attributes at the probe locations.
// .SECTION Description
// vtkProbeSelectedLocations is similar to vtkExtractSelectedLocations except
// that it interpolates the point attributes at the probe location. This is
// equivalent to the vtkProbeFilter except that the probe locations are provided
// by a vtkSelection. The FieldType of the input vtkSelection is immaterial and
// is ignored. The ContentType of the input vtkSelection must be
// vtkSelection::LOCATIONS.
