// .NAME vtkPassThroughLayoutStrategy - a layout strategy that does absolutely nothing
//
// .SECTION Description
// Yes, this incredible strategy does absoluted nothing to the data
// so in affect passes through the graph untouched. This strategy
// is useful in the cases where the graph is already laid out.

// Description:
// This is the layout method where the graph that was
// set in SetGraph() is laid out. The method can either
// entirely layout the graph or iteratively lay out the
// graph. If you have an iterative layout please implement
// the IsLayoutComplete() method.

// I'm an iterative layout so this method lets the caller
