61257bc2de [libpng16] Update CHANGES and ANNOUNCE 2015-09-25 18:25:08 -05:00

c3e7e7d715 [libpng16] tests backported from libpng 1.7 
This updates libpng16 with all the test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used.

pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7.  More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progresive-read (there is a separate test which does
that.)

Some signed/unsigned fixes have been made.

b26b51d154 [libpng16] Quieted Coverity issues in pngfix.c, png-fix-itxt.c, pngvalid.c, 
pngstest.c, and pngimage.c. Most seem harmless, but png-fix-itxt
would only work with iTXt chunks with length 255 or less.

61ea3eacb0 [libpng16] Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING 
in the manual, example.c, pngtest.c, and applications in the contrib directory.
It was incorrect advice.

6f2c50e7fc [libpng16] Free all allocated memory in pngimage. The file buffer cache was left 
allocated at the end of the program, harmless but it causes memory
leak reports from clang.
