Version 1.6.20rc02 [November 29, 2015]
In libpng 1.6 zlib initialization was changed to use the window size
in the zlib stream, not a fixed value. This causes some invalid images,
where CINFO is too large, to display 'correctly' if the rest of the
data is valid. This provides a workaround for zlib versions where the
error arises (ones that support the API change to use the window size
in the stream).
