Log Message:
Version 1.7.85 (built with libpng-1.6.16 and zlib-1.2.8)
  Improved reporting of invalid chunk names. Does not try to put
    non-printable characters in STDERR; displays hex numbers instead.
  Fixed include path for utime.h on MSVC (Louis McLaughlin).
  Eliminated "FAR" memory support (it was removed from libpng at version
    1.6.0).
  Disabled the "-already_crushed" option which does not really work well.
