1faa6ff32c [libpng17] Handle zero-length PLTE chunk or NULL palette with png_error() 
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette().

3adf438f39 [libpng17] Made transform implementation functions static. This makes the 
internal functions called by png_do_{read|write}_transformations static.
On an x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.

d45a632529 [libpng17] Bookkeeping: Moved functions around (no changes). Moved transform 
function definitions before the place where they are called so that
they can be masde static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c

05f896004f [libpng17] Changed tabs to 3 spaces in png_debug macros and changed '"%s"m' 
to '"%s" m' to improve portability among compilers.
Changed png_free_default() to free() in pngtest.c

7e2707e2af [libpng17] Ported recent changes from libpng16 to libpng17 
Fixed 'minimal' builds. Various obviously useful minimal configurations
  don't build because of missing contrib/libtests test programs and overly
  complex dependencies in scripts/pnglibconf.dfa. This change adds
  contrib/conftest/*.dfa files that can be used in automatic build
  scripts to ensure that these configurations continue to build.
Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.

9f2fbcf5d8 [libpng17] Fixed #include in filter_neon_intrinsics.c and ctype macros. The 
ctype char checking macros take an unsigned char argument, not a signed char.

72c2577302 [libpng17] Make autogen.sh work with automake 1.13 as well as 1.14. Do this 
by always removing the 1.14 'compile' script but never checking for it.

091fab713c [libpng17] Simplified error message code in pngunknown. The simplification has 
the useful side effect of avoiding a bogus warning generated by the latest
version of the Intel C compiler (it objects to
condition ? string-literal : string-literal).

32aeb2cd4e [libpng17] 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

c1bcdc3a86 [libpng17] Made changes for compatibility with automake 1.14: 
1) Added the 'compile' program to the list of programs that must be cleaned
       in autogen.sh
    2) Added 'subdir-objects' which causes .c files in sub-directories to be
       compiled such that the corresponding .o files are also in the
       sub-directory.  This is because automake 1.14 warns that the
       current behavior of compiling to the top level directory may be removed
       in the future.
    3) Updated dependencies on pnglibconf.h to match the new .o locations and
       added all the files in contrib/libtests and contrib/tools that depend
       on pnglibconf.h
    4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
       way of handling the dependencies of sources that are machine generated;
       unfortunately it only works if the user does 'make all' or 'make check',
       so the dependencies (3) are still required.

d9f60caf72 [libpng17] Fixed default behavior of ARM_NEON_API. If the ARM NEON API option is 
compiled without the CHECK option it defaulted to on, not off.
