Received this bug report: https://sourceforge.net/p/libpng/bugs/265/
libpng16 is adding an extra zero-length IDAT when the zlib buffer
for the final IDAT is exactly filled by the data. I've confirmed that
the bug exists in libpng-1.6.13 through 1.6.30beta03 but not in
libpng-1.5.29 and earlier.
A bugfix would be welcome.
Glenn
