* Mon Jul 01 2013
  - updated to 1.5.17:
    Removed a redundant test from png_set_IHDR().
    Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt)
    Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt
    Make ARM NEON support work at compile time (not just configure time).
      This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
      using a compiler that compiles for multiple architectures at one time.
      pnglibconf.h, allowing more of the decisions to be made internally
      (pngpriv.h) during the compile.  Without this, symbol prefixing is broken
      under certain circumstances on ARM platforms.  Now only the API parts of
      the optimizations ('check' vs 'api') are exposed in the public header files
      except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
      decision about whether or not to use the optimizations.
    Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage.
      Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
      on __ARM_NEON__ from configure time to compile time.  This breaks symbol
      prefixing because the definition of the special png_init_filter_functions
      call was hidden at configure time if the relevant compiler arguments are
      passed in CFLAGS as opposed to CC.  This change attempts to avoid all
      the confusion that would result by declaring the init function even when
      it is not used, so that it will always get prefixed.
    Revised libpng.3 so that "doclifter" can process it.
    Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18
      as parameters for png_set_gamma().  These have been available since
* Thu May 23 2013
  - updated to 1.5.16:
    Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
      (Flavio Medeiros).
    Revised stack marking in arm/filter_neon.S and
    Ensure that NEON filter stuff is completely disabled when switched 'off'.
      Previously the ARM NEON specific files were still built if the option
      was switched 'off' as opposed to being explicitly disabled.
    Avoid a compiler warning about unused png_ptr in translate_gamma_flags()
    Revise pngtest.c to skip tests of unsupported features.
    Test for 'arm*' not just 'arm' in the host_cpu configure variable.
    Rebuilt the configure scripts.
    Expanded manual paragraph about writing private chunks, particularly
      the need to call png_set_keep_unknown_chunks() when writing them.
    Updated contrib/pngminus/pnm2png.c (Paul Stewart):
      Check for EOF
      Ignore "#" delimited comments in input file to pnm2png.c.
      Fixed whitespace handling
      Added a call to png_set_packing()
      Initialize dimension values so if sscanf fails at least we have known
      invalid values.
    Allow contrib/pnminus/pnm2png.c to compile without WRITE_INVERT and
      WRITE_PACK supported (writes error message that it can't read P1 or P4
      PBM files).
    Revised contrib/pngminim/*/makefile to separate CPPFLAGS and CFLAGS, and
      to generate pnglibconf.h with the right zlib header files.
    Ported contrib/pngminus/pnm2png.c changes back from libpng-1.6.3beta06,
      to use unsigned long, not png_uint_32 arguments to sscanf().
* Mon Apr 15 2013
  - Added url as source.
    Please see
* Thu Mar 28 2013
  - updated to 1.5.15:
    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.
    Added png_get_palette_max() function.
    Made a probably general fix for the preprocessing used to generate source
      files. This change might make the check for a special C preprocessor
      unnecessary, and it also eliminates the requirement for sed in the
      configure build process.
    Turn serial tests back on (recently turned off by autotools upgrade).
    Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED
      block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly.
    Fixed a race condition in the creation of the build 'scripts' directory
      while building with a parallel make.
    Use parentheses more consistently in "#if defined(MACRO)" tests.
    Fixed PNG_ALIGN(ED)_MEMORY and add ability to turn off ARM_NEON
      runtime checks
    Updated the INSTALL document.
    Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES.
    Avoid a possible memory leak in contrib/gregbook/readpng.c
    etc. see ANNOUNCE or CHANGES
* Tue Jan 29 2013
  - updated to 1.5.14:
    Ignore, with a warning, out-of-range value of num_trans in png_set_tRNS().
    Fixed a minor bug in types to malloc and major bug in handling compressed
      iTXt. Compressed iTXt could not be handled.
    Check validity of "num_unknowns" parameter of png_set_unknown_chunks()
      (Bug report from yuris).
    Check the validity of the "nentries" parameter of png_set_sPLT() and the
    "num_text" parameter of png_set_text_2().
* Wed Oct 24 2012
  - Add missing baselib requires for compat-devel-32bit
* Thu Sep 27 2012
  - updated to 1.5.13:
    Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
    Removed references to png_zalloc() and png_zfree() from the manual.
    Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
      lone semicolons (patch ported from libpng-1.6.0beta11).
    Corrected handling of the image array and the row_pointers array in example.
    When png_set_filler is used to strip a filler channel during write, the
      code prior to 1.5 would ignore the case where the output required an
      alpha channel or when the output was a palettized PNG.  In libpng-1.5 the
      ignorance was lost and libpng proceeded to strip the channel resulting
      in a bad (potential memory overwrite) failure later.  This reverts
      the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
      expected to issue an error on the erroneous png_set_filler call.
    Use png_memset() consistently (pngmem.c contained some bare "memset" calls).
* Wed Jul 11 2012
  - updated to 1.5.12:
    Changed "a+w" to "u+w" in to fix CVE-2012-3386.
* Fri Jun 15 2012
  - updated to 1.5.11:
    Enable png_set_check_for_invalid_index() for both read and write.
    Made fixes for new optimization warnings from gcc 4.7.0. The compiler
      performed an optimization which is safe but then warned about it.
      Changing the type of 'palette_number' in pngvalid.c removes the warning.
    Improved efficiency of new do_check_palette_indexes() function.
    Don't check palette indexes if num_palette is 0 (as it can be in MNG files).
    Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
      and renamed three whose names were inconsistent with those in
* Thu Mar 29 2012
  - updated to 1.5.10:
    Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
    Always put the CMAKE_LIBRARY in "lib" (removed special WIN32 case).
    Removed empty vstudio/pngstest directory (Clifford Yapp).
    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).
    Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h
      to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
      To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED" on the configure
      command or put "#define PNG_SAFE_LIMITS_SUPPORTED" in pnglibconf.h.
    Revised the SAFE_LIMITS feature to be the same as the feature in libpng16.
    Added information about the new limits in the manual.
    Removed unused "current_text" members of png_struct and the png_free()
      of png_ptr->current_text from pngread.c
    Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
    Fixed CMF optimization of non-IDAT compressed chunks, which was added at
      libpng-1.5.4.  It sometimes produced too small of a window.
    Reject all iCCP chunks after the first, even if the first one is invalid.
    Added palette-index checking. Issue a png_benign_error() if an invalid
      index is found.
    Revised example.c to put text strings in a temporary character array
      instead of directly assigning string constants to png_textp members.
      This avoids compiler warnings when -Wwrite-strings is enabled.
    Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
    Revised png_set_text_2() to avoid potential memory corruption (fixes
* Mon Feb 20 2012
  - updated to 1.5.9:
    * fixed CVE-2011-3026 [bnc#747311]
* Thu Feb 02 2012
  - updated to 1.5.8:
    Fixed one-byte (stack) buffer-overrun bug in png_formatted_warning()
* Mon Dec 19 2011
  - updated to 1.5.7:
    Added support for ARM processor (Mans Rullgard)
    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.
    Fix for the preprocessor of the Intel C compiler. The preprocessor
      splits adjacent @ signs with a space; this changes the concatentation
      token from @-@-@ to PNG_JOIN; that should work with all compiler
    Paeth filter speed improvements from work by Siarhei Siamashka. This
      changes the 'Paeth' reconstruction function to improve the GCC code
      generation on x86. The changes are only part of the suggested ones;
      just the changes that definitely improve speed and remain simple.
      The changes also slightly increase the clarity of the code.
    Check compression_type parameter in png_get_iCCP and remove spurious
      casts. The compression_type parameter is always assigned to, so must
      be non-NULL. The cast of the profile length potentially truncated the
      value unnecessarily on a 16-bit int system, so the cast of the (byte)
      compression type to (int) is specified by ANSI-C anyway.
    Fixed FP division by zero in pngvalid.c; the 'test_pixel' code left
      the sBIT fields in the test pixel as 0, which resulted in a floating
      point division by zero which was irrelevant but causes systems where
      FP exceptions cause a crash. Added code to pngvalid to turn on FP
      exceptions if the appropriate glibc support is there to ensure this is
      tested in the future.
    Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the
      new PNG_JOIN macro.
    Added versioning to pnglibconf.h comments.
    Simplified read/write API initial version; basic read/write tested on
      a variety of images, limited documentation (in the header file.)
    Installed more accurate linear to sRGB conversion tables. The slightly
      modified tables reduce the number of 16-bit values that
      convert to an off-by-one 8-bit value.  The "makesRGB.c" code that was used
      to generate the tables is now in a contrib/sRGBtables sub-directory.
    etc. see CHANGES
* Thu Dec 01 2011
  - Name field shouldn't contain a macro
* Thu Dec 01 2011
  - add libtool as buildrequire to avoid implicit dependency
* Thu Nov 03 2011
  - updated to 1.5.6:
    Fixed some 64-bit type conversion warnings in pngrtran.c
    Moved row_info from png_struct to a local variable.
    The various interlace mask arrays have been made into arrays of
      bytes and made PNG_CONST and static (previously some arrays were
      marked PNG_CONST and some weren't).
    Additional checks have been added to the transform code to validate the
      pixel depths after the transforms on both read and write.
    Removed some redundant code from pngwrite.c, in png_desgtroy_write_struct().
    Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4].
      This removes the need to allocate temporary strings for chunk names on
      the stack in the read/write code.  Unknown chunk handling still uses the
      string form because this is exposed in the API.
    Added a note in the manual the png_read_update_info() must be called only
      once with a particular info_ptr.
    Revised to report FAIL when pngtest fails.
    Added "--strict" option to pngtest, to report FAIL when the failure is
      only because the resulting valid files are different.
    Revised CMakeLists.txt to work with mingw and removed some material from
      CMakeLists.txt that is no longer useful in libpng-1.5.
    Fixed typo in and ("-M Wl" should be "-M -Wl")."
    Speed up png_combine_row() for interlaced images. This reduces the generality
      of the code, allowing it to be optimized for Adam7 interlace.  The masks
      passed to png_combine_row() are now generated internally, avoiding
      some code duplication and localizing the interlace handling somewhat.
    Align png_struct::row_buf - previously it was always unaligned, caused by
      a bug in the code that attempted to align it; the code needs to subtract
      one from the pointer to take account of the filter byte prepended to
      each row.
    Optimized png_combine_row() when rows are aligned. This gains a small
      percentage for 16-bit and 32-bit pixels in the typical case where the
      output row buffers are appropriately aligned. The optimization was not
      previously possible because the png_struct buffer was always misaligned.
    Removed two redundant tests for unitialized row.
    Fixed a relatively harmless memory overwrite in compressed text writing
      with a 1 byte zlib buffer.
    Add ability to call png_read_update_info multiple times to pngvalid.c
    Fixes for multiple calls to png_read_update_info. These fixes attend to
      most of the errors revealed in pngvalid, however doing the gamma work
      twice results in inaccuracies that can't be easily fixed.  There is now
      a warning in the code if this is going to happen.
    Turned on multiple png_read_update_info in pngvalid transform tests.
    Prevent libpng from overwriting unused bits at the end of the image when
      it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
      overwrite the partial byte at the end of each row if the row width was not
      an exact multiple of 8 bits and the image is not interlaced.
    Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
      (Mans Rullgard).
    Changed misleading "Missing PLTE before cHRM" warning to "Out of place cHRM"
    Added PNG_LSR() and PNG_LSL() macros to defend against buggy compilers that
      evaluate non-taken code branches and complain about out-of-range shifts.
    Renamed the local variable 'byte' because it appears in a MSYS header
    Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/*/pngusr.h

    * Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin
      and contrib/pngminim/*/makefile
    * Relocated png_do_chop() to its original position in pngrtran.c; the
