// .NAME vtkSQLineSource - create a line defined by two end points
// .SECTION Description
// vtkSQLineSource is a source object that creates a polyline defined by
// two endpoints. The number of segments composing the polyline is
// controlled by setting the object resolution.
//
// Modified to work with the dynamic load ballancing of the SQ Field Tracer.
