Latest changes:


26-Feb-2012  GBM.DLL 1.75
             * TGA codec
               - Add support for reading and writing 1bpp gray/bw/palette images
                 (uncompressed and RLE compressed)
               - Add support for reading and writing 4bpp gray/palette images
                 (uncompressed and RLE compressed)
               - Add support for writing 8bpp gray images
               - Add support for writing RLE compressed images (all colour depths)
               - Fix write bugs (e.g. uninitialized alpha channel for 24bpp -> 32bpp)

             * ZLIB updated to version 1.2.6
             * PNG codec     : Update to Libpng 1.5.9 (with APNG extension patch)
             * JPEG codec    : Update to IJG 8d
             * JPEG2000 codec: Update to OpenJPEG 1.5
             * RAW codec     : Update to libraw 0.14.5 (based on dcraw 9.12)
             * TIFF codec    : Will not be upgraded to libtiff 4.0.1 because then
                               the old IBM VAC compiler cannot be supported anymore
                               (64bit ints are required now). Also the new libtiff
                               mainly provides new support for BigTIFF which is not
                               widely spread. So there is no need for an upgrade.

             GBMV2 1.59, GBM File Dialog 1.59
             * Update online help for TGA codec (new formats added)

             GBM plugin for Netscape/Mozilla/Firefox/SeaMonkey (NPGBM.DLL version 1.46)
             * Included gbm.dll updated to version 1.75
               -> Minimum required version is still 1.73 though update is encouraged
             
             OpenJPEG codec tools 1.5.0
             * Now using OpenJPEG 1.5
             * Now using IJG JPEG 8d, Libpng 1.5.9, Zlib 1.2.6
