// .NAME vtkValuePainter - painter that renders arrays encoded into
// pixel colors.
// .SECTION Description
// vtkValuePainter renders polygonal geometry where data values
// are encoded into 24 bit integers and send to the screen.
// The pixel colors can then be read and converted back into values later.
//
// .SECTION See Also
