Latest changes:

13-Nov-2010  GBM.DLL 1.71
             * RAW codec
               - Update to libraw 0.11.2 (based on dcraw 9.05)
               - All supported RAW formats checked with some sample images
                 (added missing extensions, removed unsupported extensions like Sigma Foveon)
               - Better handling of additional rows/columns due to rounding accuracy
                 (between image info and post decoding size)
               - Fix wrong image size when combining halfsize and aber or denoise params
               - Default interpolation quality is now 2 (PPG) as a good compromise
                 between performance and quality
               - Allow manual gamma adjustment, default is sRGB
               - Add options for clipping, saturation, blacklevel and four color RGGB interpolation
               - Allow disabling camera withe balance correction

             * PNG codec:

             * Add resampling scaler filters:
               - blackman, catmullrom, quadratic, gaussian, kaiser
             * Final fix for sometimes generated moire due to rounding issues
               in sample contribution calculations.
