4b4700ceca Usage message, ability to cache the test set 
This makes tests slightly quicker by allowing the temporary file to be created
beforehand.

0df91242a2 [libpng16] Update CHANGES and ANNOUNCE, about timepng.c 2016-02-26 19:35:59 -06:00

9821954ecc contrib/libtests/timepng: make robust, improve 
The code no longer gives up/fails on invalid PNG data, it just skips it (with
error messages).  The code no longer fails on PNG files with data beyond IEND.
Options exist to use png_read_png (reading the whole image, not by row) and, in
that case, to apply any of the supported transforms.  This makes for more
realistic testing; the decoded data actually gets used in a meaningful fashion.

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.

294d0b8408 [libpng16] Detect wrong libpng versions linked to pngdeflate, which currently 
only works with libpng versions that can be made to reliably fail when
    the deflate data contains an out-of-window reference.  This means only
    1.6 and later.
  Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
    message which it is easier to work round than ignore.
