    alongside zlib by another project (Sam Serrels).
  Changed png_ptr->options from a png_byte to png_uint_32, to accomodate
    up to 16 options.

Version 1.6.28beta02 [January 4, 2017]
  Added "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
  Moved SSE2 optimization code into the main libpng source directory.
