08b0620202 [libpng16] Fixed #include in filter_neon_intrinsics.c and ctype macros. The 
ctype char checking macros take an unsigned char argument, not a signed char.

5b1df53a82 [libpng16] Cleaned up (char*) casts of zlib messages. The latest version of 
the Intel C compiler complains about casting a string literal as (char*), so
copied the treatment of z_const from the library code into pngfix.c

f5f1206778 [libpng16] Fixed undefined behavior in contrib/tools/pngfix.c and added new 
strip option. pngfix relied on undefined behavior and even a simple change from
gcc to g++ caused it to fail.  The new strip option 'unsafe' has been
implemented and is the default if --max is given.  Option names have
been clarified, with --strip=transform now stripping the bKGD chunk,
which was stripped previously with --strip=unused.
Added all documented chunk types to pngpriv.h

ff141eb21e [libpng16] Renamed contrib/tools/fixitxt to contrib/tools/png-fix-itxt. 
Added information in the documentation about problems with and fixes for
the bad CRC and bad iTXt chunk situations.

9afb90f885 [libpng16] Attempt to detect configuration issues with pngdeflate, 
which requires both the correct libpng and the correct zlib to function
correctly.

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.

0c7ac064d3 [libpng16] Added an option to force maximum window size for inflating. 
For inflate, reverted previous fixes.
Added fixitxt and pngdeflate to the built programs and removed warnings
from the source code and timepng that are revealed as a result.  Fixed
fixitxt when the chunk length is more than 65535 (untested, no test case).

f1736a636b [libpng16] Added contrib/tools/fixitxt.c, to repair the erroneous iTXt 
chunk length written by libpng-1.6.0 and 1.6.1.
