* @class vtkLineSource
* @brief create a line defined by two end points
*
* vtkLineSource 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.
*
* @par Thanks:
* This class was extended by Philippe Pebay, Kitware SAS 2011, to support
* broken lines as well as simple lines.
