af759fb3fe [libpng15] Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that 
interferes with "blocky" expansion of sub-8-bit interlaced PNG files.

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).

ec89c54e42 [libpng16] Choose to use windowBits==15 or the zlib header setting via the 
benign-errors setting.  If benign errors are allowed, then ignore
the windowBits setting in the zlib header.
Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so
undid the improvement in beta04.

a2669c39c3 [libpng15] Fixed a minor bug in types to malloc and major bug in handling 
compressed iTXt. Compressed iTXt could not be handled. Change was made
earlier but omitted from libpng-1.5.14beta02 distributions.

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.

0ff5150f91 [libpng15] Reject all iCCP chunks after the first, 
even if the first one is invalid.

8a2033d77f [libpng15] Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from 
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.

Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
