8a6253ed6f [libpng15] Merged pngtest.c with libpng-1.6.17/pngtest.c 
Display user limits in the output from pngtest.
Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
  and 1-million-row default limits in pnglibconf.dfa, that can be reset
  by the user at build time or run time.  This provides a more robust
  defense against DOS and as-yet undiscovered overflows.

7852e7786b [libpng15] Use memcpy instead of CopyMemory in the definition of png_memcpy. 
The Borland C++ build breaks otherwise (Cosmin).

71fcb39efc [libpng15] Merged pngvalid and pngtest from libpng-1.5; made compressed chunks 
after IDAT work with the progressive read code (this is a minor and
somewhat ugly fix-up; the proper fix is in 1.6).

bd7143e6eb [libpng15] Fixed 'unused' warnings and mergeed with libpng16 pngvalid. 
Various warnings revealed by configurations added to the tested
configurations in libpng 1.6 need corresponding fixes in libpng 1.5.
This takes the libpng 1.6 pngvalid.c and adds it back to libpng 1.5,
however one write-only test is currently disabled because it does not
work; possibly because of failures to reset or initialize the deflate
stream correctly in write-only cases.

c9f2269857 [libpng15] Enabled renaming of the extern (but not DLL exported) ARM filter 
functions.  Also enabled inclusion of pngpriv.h in non-C files by preventing
C/C++ specific definitions if PNG_VERSION_INFO_ONLY is defined.

84dc479108 [libpng15] De-configured build fixes to make a range of deconfiguration options 
(such as switching off read or write support) work in more cases.  Also
upgraded pngtest and pngvalid to the libpng 1.6 versions (with some
modifications) which provide more extensive testing.  Replaced pngtest.png
because pngtest writes the ancillary chunks in a different order.

62cfc893e0 [libpng15] Rearranged building of ARM NEON optimizations. The ARM specific code 
is split out entirely to the arm subdirectory and changes to configure.ac and
Makefile.am to add new stuff are reduced.  Now material code changes,
although for build test purposes, --enable-arm-neon now builds on non-ARM
systems.
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.2.5.

17878c6e65 [libpng15] Work around compilers that don't support declaration of const data. 
Some compilers fault 'extern const' data declarations (because the data is
not initialized); this turns on const-ness only for compilers where
this is known to work.

4fa96a42f7 [libpng15] Fixes for C++ compilation using g++ When libpng source is compiled 
using g++. The compiler imposes C++ rules on the C source; thus it
    is desireable to make the source work with either C or C++ rules
    without throwing away useful error information.  This change adds
    png_voidcast to allow C semantic (void*) cases or the corresponding
    C++ static_cast operation, as appropriate.

aff44028ba [libpng15] Fixed bug in pngvalid on early allocation failure; fixed type cast 
in pngmem.c; pngvalid would attempt to call png_error() if the allocation
of a png_struct or png_info failed. This would probably have led to a
crash.  The pngmem.c implementation of png_malloc() included a cast
to png_size_t which would fail on large allocations on 16-bit systems.
