110 fixed gamma and background correction for paletted images, so
195 fixed bug in gamma handling of 4-bit grayscale
196 added 2-bit grayscale gamma handling (Glenn R-P)
300 Fixed three bugs in pngrtran.c to make gamma+background handling consistent
369 error that was introduced in libpng-0.90 that can cause gamma processing
442 Correct gamma with srgb is 45455 instead of 45000 in pngrutil.c, to be
941 Added warnings when retrieving or setting gamma=0.
1021 Include background_1 in png_struct regardless of gamma support.
1057 Added checks for gamma and chromaticity values over 21474.83, which exceed
1067 Always do gamma compensation when image is partially transparent.
1088 Compute gamma for color components of background even when color_type is gray.
1428 Moved test for nonzero gamma outside of png_build_gamma_table() in pngrtran.c
2041 Prevent gamma from being applied twice.
2361 Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
