// .NAME vtkImageQuantizeRGBToIndex - generalized histograms up to 4 dimensions
// .SECTION Description
// vtkImageQuantizeRGBToIndex takes a 3 component RGB image as
// input and produces a one component index image as output, along with
// a lookup table that contains the color definitions for the index values.
// This filter works on the entire input extent - it does not perform
// streaming, and it does not supported threaded execution (because it has
// to process the entire image).
//
// To use this filter, you typically set the number of colors
// (between 2 and 65536), execute it, and then retrieve the lookup table.
// The colors can then be using the lookup table and the image index.
