* Check that the eXIf chunk has at least 2 bytes and begins with \"II\" or \"MM\".
* Added a set of \"huge_xxxx_chunk.png\" files to contrib/testpngs/crashers, one for each known chunk type, with length = 2GB-1.
* Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts in contrib/pngminus/
*.c to stop some Coverity issues (162705, 162706, and 162707).
* Renamed chunks in contrib/testpngs/crashers to avoid having files whose names differ only in case; this causes problems with some platforms
* Added contrib/oss-fuzz directory which contains files used by the oss-fuzz project- cleanup with spec-cleaner
* Mon Aug 07 2017 pgajdosAATTsuse.com- update to 1.6.31:

* Wed Jul 19 2017 stefan.bruensAATTrwth-aachen.de- Drop png-version-info-only.patch, it has no effect after applying 0001-libpng16-Revised-pngpriv.h-to-use-PNG_VERSION_INFO_O.patch Both patches achieve the same, prefer the upstream version
* Fri Jul 14 2017 stefan.bruensAATTrwth-aachen.de- Add 0001-libpng16-Revised-pngpriv.h-to-use-PNG_VERSION_INFO_O.patch Fix build on ARM
* Mon Jul 10 2017 schwabAATTsuse.de- png-version-info-only.patch: fix missing PNG_VERSION_INFO_ONLY check
* Fri Jun 30 2017 pgajdosAATTsuse.com- update to 1.6.30: Revised documentation of png_get_error_ptr() in the libpng manual. Document need to check for integer overflow when allocating a pixel buffer for multiple rows in contrib/gregbook, contrib/pngminus, example.c, and in the manual (suggested by Jaeseung Choi). This is similar to the bug reported against pngquant in CVE-2016-5735. Check for integer overflow in contrib/visupng and contrib/tools/genpng. Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt. Avoid writing an empty IDAT when the last IDAT exactly fills the compression buffer (bug report by Brian Baird). This bug was introduced in libpng-1.6.0. Add a reference to the libpng.download site in README.
* Thu Mar 16 2017 pgajdosAATTsuse.com- update to 1.6.29: Moved SSE2 optimization code into the main libpng source directory. Configure libpng with \"configure --enable-intel-sse\" or compile libpng with \"-DPNG_INTEL_SSE\" in CPPFLAGS to enable it. Added code for PowerPC VSX optimisation (Vadim Barkov). Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).
* Fri Jan 06 2017 pgajdosAATTsuse.com- update to 1.6.28: fix build issues
* Mon Jan 02 2017 pgajdosAATTsuse.com- update to 1.6.27: fixes CVE-2016-10087
* Thu Oct 20 2016 pgajdosAATTsuse.com- update to 1.6.26: Fixed handling zero length IDAT in pngfix (bug report by Agostino Sarubbo, bugfix by John Bowler). Do not issue a png_error() on read in png_set_pCAL() because png_handle_pCAL has allocated memory that libpng needs to free. Issue a png_benign_error instead of a png_error on ADLER32 mismatch while decoding compressed data chunks. Changed PNG_ZLIB_VERNUM to ZLIB_VERNUM in pngpriv.h, pngstruct.h, and pngrutil.c. If CRC handling of critical chunks has been set to PNG_CRC_QUIET_USE, ignore the ADLER32 checksum in the IDAT chunk as well as the chunk CRCs. Issue png_benign_error() on ADLER32 checksum mismatch instead of png_error(). Updated the documentation about CRC and ADLER32 handling. Fixed offsets in contrib/intel/intel_sse.patch Changed integer constant 4294967294 to unsigned 4294967294U in pngconf.h to avoid a signed/unsigned compare in the preprocessor. Use zlib-1.2.8.1 inflateValidate() instead of inflateReset2() to optionally avoid ADLER32 evaluation.
* Thu Sep 01 2016 pgajdosAATTsuse.com- update to 1.6.25: Reject oversized iCCP profile immediately. Conditionally compile png_inflate(). Don\'t install pngcp; it conflicts with pngcp in the pngtools package. Added MIPS support (Mandar Sahastrabuddhe <
* Thu Aug 04 2016 pgajdosAATTsuse.com- update to 1.6.24: Avoid potential overflow of the PNG_IMAGE_SIZE macro. Correct filter heuristic overflow handling. Use a more efficient absolute value calculation on SSE2. Added pngcp. etc. see ANNOUNCE
* Wed Aug 03 2016 rpmAATTfthiessen.de- Update to new upstream release 1.6.23
* Fixes a potential memleak in png_set_tRNS.
* Fixed the progressive reader to handle empty first IDAT chunk properly.
* Added tests in pngvalid.c to check zero-length IDAT chunks in various positions.
* Fixed the sequential reader to handle these more robustly.
* Corrected progressive read input buffer in pngvalid.c.
* Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch.
* Fixed undefined behavior in png_push_save_buffer(). Do not call memcpy() with a null source, even if count is zero.
* Fixed bad link to RFC2083 in png.5.
* Thu May 26 2016 pgajdosAATTsuse.com- update to 1.6.22: Added a png_image_write_to_memory() API and a number of assist macros to allow an application that uses the simplified API write to bypass stdio and write directly to memory. Relaxed limit checks on gamma values in pngrtran.c. As suggested in the comments gamma values outside the range currently permitted by png_set_alpha_mode are useful for HDR data encoding. These values are already permitted by png_set_gamma so it is reasonable caution to extend the png_set_alpha_mode range as HDR imaging systems are starting to emerge. Restored \"& 0xff\" in png_save_uint_16() and png_save_uint_32() that were accidentally removed from libpng-1.6.17. Changed PNG_INFO_cHNK and PNG_FREE_cHNK from 0xnnnn to 0xnnnnU in png.h (Robert C. Seacord). Added INTEL-SSE2 support (Mike Klein and Matt Sarett, Google, Inc.). SSE filter speed improvements for bpp=3: memcpy-free implementations of load3() / store3(). Added PNG_FAST_FILTERS macro (defined as PNG_FILTER_NONE|PNG_FILTER_SUB|PNG_FILTER_UP).
* Sun Jan 17 2016 jengelhAATTinai.de- Update to new upstream release 1.6.21
* Widened the \'limit\' check on the internally calculated error limits in the \'DIGITIZE\' case (the code used prior to 1.7 for rgb_to_gray error checks) and changed the check to only operate in non-release builds (base build type not RC or RELEASE.)
* Fixed undefined behavior in pngvalid.c, undefined because (png_byte) << shift is undefined if it changes the signed bit (because png_byte is promoted to int). The libpng exported functions png_get_uint_32 and png_get_uint_16 handle this.
* Thu Dec 03 2015 pgajdosAATTsuse.com- update to 1.6.20: Avoid potential pointer overflow/underflow in png_handle_sPLT() and png_handle_pCAL() (Bug report by John Regehr). Fixed incorrect implementation of png_set_PLTE() that uses png_ptr not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126 vulnerability. Backported tests from libpng-1.7.0beta69. Fixed an error in handling of bad zlib CMINFO field in pngfix, found by American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn\'t immediately fault a bad CMINFO field; instead a \'too far back\' error happens later (at least some times). pngfix failed to limit CMINFO to the allowed values but then assumed that window_bits was in range, triggering an assert. The bug is mostly harmless; the PNG file cannot be fixed. In libpng 1.6 zlib initialization was changed to use the window size in the zlib stream, not a fixed value. This causes some invalid images, where CINFO is too large, to display \'correctly\' if the rest of the data is valid. This provides a workaround for zlib versions where the error arises (ones that support the API change to use the window size in the stream).
* Fri Nov 13 2015 pgajdosAATTsuse.com- update to 1.6.19: Fixed potential leak of png_pixels in contrib/pngminus/pnm2png.c Fixed uninitialized variable in contrib/gregbook/rpng2-x.c Fixed the recently reported 1\'s complement security issue. Fixed png_save_int_32 when int is not 2\'s complement by replacing the value that is illegal in the PNG spec, in both signed and unsigned values, with 0. etc., see ANNOUNCE and CHANGES for details- removed: libpng-rgb_to_gray-checks.patch (upstreamed)
* Sat Oct 24 2015 goedhart.martijnAATTgmail.com- enable static library
* Fri Aug 07 2015 pgajdosAATTsuse.com- drop unknown configure switch
* Wed Apr 01 2015 pgajdosAATTsuse.com- Fixed rgb_to_gray checks and added tRNS checks to pngvalid.c. + libpng-rgb_to_gray-checks.patch
* Mon Mar 30 2015 pgajdosAATTsuse.com- updated to 1.6.17: Corrected the width limit calculation in png_check_IHDR(). Removed user limits from pngfix. Also pass NULL pointers to png_read_row to skip the unnecessary row de-interlace stuff. Implement previously untested cases of libpng transforms in pngvalid.c Fixed byte order in 2-byte filler, in png_do_read_filler(). Made the check for out-of-range values in png_set_tRNS() detect values that are exactly 2^bit_depth, and work on 16-bit platforms. Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47. Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and pngset.c to avoid warnings about dead code. Do not build png_product2() when it is unused. 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. Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default. Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins). Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block of png.h. Free the unknown_chunks structure even when it contains no data. Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha value was wrong. It\'s not clear if this affected the final stored value; in the obvious code path the upper and lower 8-bits of the alpha value were identical and the alpha was truncated to 8-bits rather than dividing by 257 (John Bowler).
* Tue Jan 13 2015 pgajdosAATTsuse.com- build with PNG_SAFE_LIMITS_SUPPORTED [bnc#912076], [bnc#912929]
* Mon Dec 29 2014 pgajdosAATTsuse.com- updated to 1.6.16:
* Restored a test on width that was removed from png.c at libpng-1.6.9 (Bug report by Alex Eubanks).
* Fixed an overflow in png_combine_row with very wide interlaced images.
* Thu Nov 20 2014 pgajdosAATTsuse.com- updated to 1.6.15:
* Avoid out-of-bounds memory access in png_user_version_check().
* Fixed incorrect handling of the iTXt compression.
* Free all allocated memory in pngimage.
* Fixed array size calculations to avoid warnings. etc. see ANNOUNCE
* Fri Aug 22 2014 pgajdosAATTsuse.com- updated to 1.6.13: a \"cleanup\" release that have no security fixes or new features.
* Thu Jun 12 2014 pgajdosAATTsuse.com- updated to 1.6.12:
* bugfixes, almost build-related only
* Fri Jun 06 2014 pgajdosAATTsuse.com- updated to 1.6.11:
* fixed CVE-2014-0333
* other bugfixes- removed libpng16-1.6.9-CVE-2014-0333.patch (upstreamed)
* Tue Mar 04 2014 pgajdosAATTsuse.com- fixed CVE-2014-0333 [bnc#866298]- added patches:
* libpng16-1.6.6-CVE-2014-0333.patch
* Fri Feb 07 2014 pgajdosAATTsuse.com- updated to 1.6.9: 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 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. Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69 in the tar distributions. Added checks for libpng 1.5 to pngvalid.c. This supports the use of this version of pngvalid in libpng 1.5 Merged with pngvalid.c from libpng-1.7 changes to create a single pngvalid.c Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0 Merged libpng-1.7.0 changes to make no-interlace configurations work with test programs. Revised pngvalid.c to support libpng 1.5, which does not support the PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in pngvalid.c Allow unversioned links created on install to be disabled in configure. In configure builds \'make install\' changes/adds links like png.h and libpng.a to point to the newly installed, versioned, files (e.g. libpng17/png.h and libpng17.a). Three new configure options and some rearrangement of Makefile.am allow creation of these links to be disabled. Removed potentially misleading warning from png_check_IHDR(). Updated scripts/makefile.
* to use CPPFLAGS (Cosmin). Added clang attribute support (Cosmin).
* Fri Dec 20 2013 pgajdosAATTsuse.com- updated to 1.6.8: Changed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpread.c to [#]ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED to be consistent with what is in pngpriv.h. Moved prototype for png_handle_unknown() in pngpriv.h outside of the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block. Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder. Fixed pngvalid \'fail\' function declaration on the Intel C Compiler. This reverts to the previous \'static\' implementation and works round the \'unused static function\' warning by using PNG_UNUSED(). 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(). This is CVE-2013-6954 and VU#650142.
* Mon Dec 02 2013 pgajdosAATTsuse.com- png_fix macro doesn\'t leave
*.png.fixed (which happened for correct PNGs) [bnc#852862]
* Fri Nov 15 2013 pgajdosAATTsuse.com- updated to 1.6.7:
* Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE combination
* Check user callback behavior in pngunknown.c. Previous versions compiled if SAVE_UNKNOWN was not available but did nothing since the callback was never implemented.
* Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
* Revised pngvalid to generate size images with as many filters as it can manage, limited by the number of rows.
* ARM improvements/fixes
* Wed Sep 25 2013 pgajdosAATTsuse.com- updated to 1.6.6:
* fix arm build
* Thu Sep 12 2013 pgajdosAATTsuse.com- updated to 1.6.4:
* Added information about png_set_options() to the manual.
* Delay calling png_init_filter_functions() until a row with nonzero filter is found.
* Fixed inconsistent conditional compilation of png_chunk_unknown_handling() prototype, definition, and usage. Made it depend on PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.
* Fri Aug 30 2013 cooloAATTsuse.com- remove gpg-offline usage, libpng16 is too low in the build chain
* Thu Aug 08 2013 pgajdosAATTsuse.com- png-fix-too-far-back was actually renamed to pngfix. Adjusted rpm macro names accordingly, %png_fix and %png_fix_dir.
* Tue Aug 06 2013 pgajdosAATTsuse.com- updated to 1.6.3:
* Added png-fix-itxt and png-fix-too-far-back to the built programs and removed warnings from the source code and timepng that are revealed as a result. => new subpackage tools, created rpm macros
* Fri Jun 21 2013 crrodriguezAATTopensuse.org- Build with LFS_CFLAGS in 32 bit archs otherwise calls such as png_image_begin_read_from_file() or png_image_write_to_file() will fail to read/write huge images.- Build with Full RELRO as this library is a possible consumer of malicuous images/files.
* Fri Apr 26 2013 pgajdosAATTsuse.com- updated to 1.6.2: Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling. Fixed incorrect warning of excess deflate data. End condition - the warning would be produced if the end of the deflate stream wasn\'t read in the last row. The warning is harmless. Corrected the test on user transform changes on read. It was in the png_set of the transform function, but that doesn\'t matter unless the transform function changes the rowbuf size, and that is only valid if transform_info is called. Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c (Flavio Medeiros). Corrected length written to uncompressed iTXt chunks (Samuli Suominen). Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length written by libpng-1.6.0 and 1.6.1. Disallow storing sRGB information when the sRGB is not supported. Merge pngtest.c with libpng-1.7.0
* Tue Apr 02 2013 pgajdosAATTsuse.com- conflict with libpng12-compat-devel-32bit and libpng15-compat-devel-32bit
* Thu Mar 28 2013 pgajdosAATTsuse.com- updated to 1.6.1: Made sRGB check numbers consistent. Use parentheses more consistently in \"#if defined(MACRO)\" tests. Reenabled code to allow zero length PLTE chunks for MNG. Fixed ALIGNED_MEMORY support. Avoid a possible memory leak in contrib/gregbook/readpng.c Better documentation of unknown handling API interactions. Corrected simplified API default gamma for color-mapped output, added a flag to change default. In 1.6.0 when the simplified API was used to produce color-mapped output from an input image with no gamma information the gamma assumed for the input could be different from that assumed for non-color-mapped output. In particular 16-bit depth input files were assumed to be sRGB encoded, whereas in the \'direct\' case they were assumed to have linear data. This was an error. The fix makes the simplified API treat all input files the same way and adds a new flag to the png_image::flags member to allow the application/user to specify that 16-bit files contain sRGB data rather than the default linear. etc., see ANNOUNCE or CHANGES for details- dropped upstreamed 0387-Reenable-code-to-allow-zero-length-PLTE-chunks-for-M.patch
* Mon Mar 18 2013 pgajdosAATTsuse.com- allow zero length PLTE chunks (fixes GraphicsMagick testsuite)
* Mon Mar 04 2013 pgajdosAATTsuse.com- remove clean section
* Thu Feb 14 2013 pgajdosAATTsuse.com- updated to 1.6.0- changes from 1.5.x to 1.6.x:
* new simplified api added: macros: PNG_FORMAT_
* PNG_IMAGE_
* structures: png_control png_image read functions png_image_begin_read_from_file() png_image_begin_read_from_stdio() png_image_begin_read_from_memory() png_image_finish_read() png_image_free() write functions png_image_write_to_file() png_image_write_to_stdio()
* possibility to configure libpng to prefix all exported symbols (PNG_PREFIX macro)
* no longer include string.h in png.h
* deprecated api: png_info_init_3() png_convert_to_rfc1123() which has been replaced with png_convert_to_rfc1123_buffer() png_data_freer() png_malloc_default() png_free_default() png_reset_zstream()
* removed api: png_get_io_chunk_name()

* Mon Dec 19 2011 pgajdosAATTsuse.com- 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 AATT signs with a space; this changes the concatentation token from AATT-AATT-AATT to PNG_JOIN; that should work with all compiler preprocessors. 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 idoenmezAATTsuse.de- Name field shouldn\'t contain a macro
* Thu Dec 01 2011 cooloAATTsuse.com- add libtool as buildrequire to avoid implicit dependency
* Thu Nov 03 2011 pgajdosAATTsuse.com- 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 test-pngtest.sh 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 Makefile.in and Makefile.am (\"-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 file. Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/
