public interface ColorTweaker

Interface defining how a colour is changed from some input colour to some output colour. Two methods are defined which should perform the same transformation, but one uses Color objects and the other an sRGB array. Although it is possible to define each in terms of the other, performance can be improved considerably by implementing them both directly.
