John Bowler 8d93ec2eca pngvalid fixes and backward compat
This fix is to the PNG_MAX_GAMMA_8 handling and png_set_rgb_to_gray, which had
bugs which were likely to expose end cases of rgb-to-gray conversion errors.
This might explain some of the machine math dependencies we are seeing
(*might*).

the libpng license, although all are open source.  They are not part of
libpng proper and are not used for building the library, although some are used
for testing the library via "make check".
