Changes only pngvalid and test-pngvalid-full.sh - no libpng changes - corrects the code for palette image tests, disables attempts to validate palette colors.

This problem is present in 1.5.2; if png_set_background is called with need_expand false and the matching 16 bit color libpng erroneously just treats it as an 8-bit color because of where png_do_expand_16 is in the transform list. This simple fix reduces the supplied colour to 8 bits, so it gets smashed, but this is better than the current behavior.

png_expand_16 back where it was before libpng-1.5.3beta07. The change doesn't work because it requires 16 bit gamma tables when the code only generates 8 bit ones. This fails silently; the libpng code just doesn't do any gamma correction. Moving the tests back leaves the old, inaccurate, 8 bit gamma calculations, but these are clearly better than none!

also minor cleanup in the libpng code itself (pngrtran.c and pngrutil.c) and some extra checking there.

libpng-manual.txt. The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative parameters are supplied by the caller), while in the absence of cHRM sRGB/Rec 709 values are still used. The bKGD chunk no longer overwrites the background value set by png_set_background(), allowing the latter to be used before the file header is read. It never performed any useful function to override the default anyway. Send comments/corrections/commendations to png-mng-implement at lists.sf.net: (subscription required; visit

PNG_AFTER_IDAT from pngpriv.h to png.h because they must be visible to applications that call png_set_unknown_chunks().

minor change from the previous (unreleased) ABI/API to hide the exact value used for Macs - it's not a good idea to embed this in the ABI!

that this only affects how composited pixels are returned to the calling application; they don't affect the pixels that are written to a PNG file.
