Purpose:        Red Black Wavelet Transform with CDF(2,2) biorthogonal base
                        Used for denoising, using 2D lifting on "rectangular images"
                        The transform needs a Horizontal/Vertical step and a second
                        diagonal step.
                        It is 100% inplace and use a Gauss Seidel like scheme

                        Two schemes are used for denoising:
                              - reducing to zero small details by a hard Threshold
                                  - using wavelet shrinking for a soft threshold (Donoho)
