// .NAME vtkDijkstraImageContourLineInterpolator - Contour interpolator for placing points on an image.
//
// .SECTION Description
// vtkDijkstraImageContourLineInterpolator interpolates and places
// contour points on images. The class interpolates nodes by
// computing a graph laying on the image data. By graph, we mean
// that the line interpolating the two end points traverses along
// pixels so as to form a shortest path. A Dijkstra algorithm is
// used to compute the path.
//
// The class is meant to be used in conjunction with
// vtkImageActorPointPlacer. One reason for this coupling is a
// performance issue: both classes need to perform a cell pick, and
// coupling avoids multiple cell picks (cell picks are slow). Another
// issue is that the interpolator may need to set the image input to
// its vtkDijkstraImageGeodesicPath ivar.
