Fixed an error in handling of bad zlib CMINFO field in pngfix, found by
American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't
immediately fault a bad CMINFO field; instead a 'too far back' error

triggering an assert. The bug is mostly harmless; the PNG file cannot
be fixed.
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).
