The old version was hardcoded for noise images that were two component and floating point. The new version should handle 1-4 components (it will use the first) and it should warn if the noise input is not float. If no noise inpt was provided this class was creatnig one by default, but it was VTK_DOUBLE not float. Added an ImageCast to float to make it work like it should when using a default noise.
