libpng 1.6.36

Description
libpng is the official PNG reference library. It supports almost all PNG features, is extensible, and has been extensively tested for over 23 years. The home site for development versions (i.e., may be buggy or subject to change or include experimental features) is https://libpng.sourceforge.io/, and the place to go for questions about the library is the png-mng-implement mailing list.

libpng is available as ANSI C (C89) source code and requires zlib 1.0.4 or later (1.2.5 or later recommended for performance and security reasons). The current public release, libpng 1.6.36, fixes some build issues, adds a couple of small optimizations (ARM png_do_expand_palette(), Intel SSE2 memcpy()), and updates the license (identical terms to the zlib license, with the old license appended in the manner of the Python Software Foundation License version 2, and the list of contributing authors moved to a separate AUTHORS file).
