// .NAME vtkStandardPolyDataPainter - A standard implementation of vtkPolyDataPainter.
//
// .SECTION Description
// vtkStandardPolyDataPainter is a catch-all painter.  It should work with pretty
// much any vtkPolyData, and attributes, and vtkPolyDataPainterDeviceAdapter.  On
// the flip side, the vtkStandardPolyDataPainter will be slower than the more
// special purpose painters.
// .SECTION See Also
// vtkDefaultPainter
// .SECTION Thanks
// Support for generic vertex attributes in VTK was contributed in
// collaboration with Stephane Ploix at EDF.
