They have been combined with PNG_SET_USER_LIMITS_SUPPORTED (resolves bug report by Andrew Church). Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. This fixes some arithmetic errors that caused some tests to fail on some 32-bit platforms (Bug reports by Peter Breitenlohner [i686] and Petr Gajdos [i586]). Version 1.6.18beta02 [April 26, 2015] Suppressed some warnings from the Borland C++ 5.5.1/5.82 compiler (Bug report by Viktor Szaka'ts). Version 1.6.18beta03 [May 6, 2015] Replaced "unexpected" with an integer (0xabadca11) in pngset.c where a long was expected, to avoid a compiler warning when PNG_DEBUG > 1. Added contrib/examples/simpleover.c, to demonstrate how to handle alpha compositing of multiple images, using the "simplified API" and an example PNG generation tool, contrib/examples/genpng.c (John Bowler).
