   Log Message:
   Update to 1.2.37:

   version 1.2.37beta01 [May 14, 2009]
     Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36.  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 () statment;" 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 about using png_get_io_ptr() in configure scripts to detect
       the presence of libpng.
