/**
 * @class   vtkDefaultPainter
 * @brief   sets up a default chain of painters.
 *
 *
 * This painter does not do any actual rendering.
 * Sets up a default pipeline of painters to mimick the behaiour of
 * old vtkPolyDataMapper. The chain is as follows:
 * input--> vtkScalarsToColorsPainter --> vtkClipPlanesPainter -->
 * vtkDisplayListPainter --> vtkCompositePainter -->
 * vtkCoincidentTopologyResolutionPainter -->
 * vtkLightingPainter --> vtkRepresentationPainter -->
 * \<Delegate of vtkDefaultPainter\>.
 * Typically, the delegate of the default painter be one that is capable of r
 * rendering graphics primitives or a vtkChooserPainter which can select appropriate
 * painters to do the rendering.
