Changes since the last public release (1.4.20):
version 1.4.22beta01 [August 28. 2017]
Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing
parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse).
version 1.4.22beta02 [September 14, 2017]
Compute a larger limit on IDAT because some applications write a deflate
buffer for each row (Bug report by Andrew Church).
Fixed incorrect typecast of some arguments to png_malloc() and
png_calloc() that were png_uint_32 instead of png_alloc_size_t
(Bug report by "irwir" in Github libpng issue #175).
version 1.4.22beta03 [September 20, 2017]
Initialize memory allocated by png_inflate to zero, using memset, to
stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2()
due to truncated iTXT or zTXT chunk.
