The memset() was using "png_ptr->rowbytes" instead of "row_bytes", which the corresponding png_malloc() uses (Joe Drew). Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri) Updated some of the makefiles in the scripts directory (merged with those in libpng-1.4.0beta57). version 1.2.37beta02 [May 19, 2009] Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG) Relocated misplaced #endif in pngwrite.c, sCAL chunk handler. Conditionally compile png_read_finish_row() which is not used by progressive readers. Added contrib/pngminim/preader to demonstrate building minimal progressive decoder, based on contrib/gregbook with embedded libpng and zlib. version 1.2.37beta03 [May 20, 2009] In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there is only one makefile in those directories, and revised the README files accordingly. Reformated sources in libpng style (3-space indentation, comment format) version 1.2.37rc01 [May 27, 2009] No changes. versions 1.2.37 and 1.0.45 [June 4, 2009] Reformatted several remaining "else statement;" and "if () statement;" into two lines. Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h Added sections about the git repository and our coding style to the documentation (merged from libpng-1.4.0beta62) Added a section in the documentation about using png_get_io_ptr() in configure scripts to detect the presence of libpng. versions 1.2.38beta01 [June 17, 2009] Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR() multiple times and to specify the sample order in the tRNS chunk, because the ISO PNG specification has a typo in the tRNS table. Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism available for ignoring known chunks even when not saving unknown chunks. Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of pngconf.h, and moved the various unknown chunk macro definitions outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks. version 1.0.46 [June 18, 2009] Removed some editing cruft from scripts/libpng.pc.in and some makefiles. version 1.2.38rc01 [June 24, 2009] No changes.
