2014-12-28Change colourspace handling round a bit:1.0-colour-cleanupCarl Hetherington
- move the essence of GammaLUT into TransferFunction and handle different bit depths more neatly - add ColourConversion to describe input gamma correction, colour transformation and then output gamma correction in one class. - add default ColourConversions for sRGB->XYZ, Rec709->XYZ and XYZ->RGB.
