- updated to 1.6.27: Corrected the width limit calculation in png_check_IHDR(). Removed user limits from pngfix. Also pass NULL pointers to png_read_row to skip the unnecessary row de-interlace stuff. Implement previously untested cases of libpng transforms in pngvalid.c Fixed byte order in 2-byte filler, in png_do_read_filler(). Made the check for out-of-range values in png_set_tRNS() detect values that are exactly 2^bit_depth, and work on 16-bit platforms. Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47. Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and pngset.c to avoid warnings about dead code. Do not build png_product2() when it is unused. Display user limits in the output from pngtest. Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column and 1-million-row default limits in pnglibconf.dfa, that can be reset by the user at build time or run time. This provides a more robust defense against DOS and as-yet undiscovered overflows. Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default. Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins). Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block of png.h. Free the unknown_chunks structure even when it contains no data. Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha value was wrong. It's not clear if this affected the final stored value; in the obvious code path the upper and lower 8-bits of the alpha value were identical and the alpha was truncated to 8-bits rather than dividing by 257 (John Bowler).
