Changes to Exposure tab. Exposure controls (blackpoint, brightness, contrast, S/H compression) are now implemented with NURBS curves. Brightness bug seems fixed as a consequence. Luminance tone curve has been expanded to separate curves for L,a,b; saturation slider has been added, but at the moment saturation limiting has not been implemented in the modified tool.
