Log Message:
Update "png" package to version 1.0.6. Changes since version 1.0.5:
- Added contrib/pngsuite and contrib/pngminus (Willem van Schaik)
- Fixed a typo in the png_set_sRGB() function call in example.c (Jan Nijtmans)
- Further optimization and bugfix of pngvcrd.c
- Revised pngset.c so that it does not allocate or free memory in the user's
  text_ptr structure.- Instead, it makes its own copy.
- Added code in pngwrite.c to free info_ptr->text[i].key to stop a memory leak.
- Created separate write_end_info_struct in pngtest.c for a more severe test.
- Moved PNG_FLAG_HAVE_CHUNK_HEADER, PNG_FLAG_BACKGROUND_IS_GRAY and
  PNG_FLAG_WROTE_tIME from flags to mode.
- Added png_write_info_before_PLTE() function.
- Fixed some typecasting in contrib/gregbook/*.c
- Updated scripts/makevms.com (Martin Zinser)
- Moved png_get_header_version from png.h to png.c, to accomodate ansi2knr.
- Removed all global arrays (according to PNG_NO_GLOBAL_ARRAYS macro), to
  accomodate making DLL's: Moved usr_png_ver from global variable to function
  png_get_header_ver() in png.c.- Moved png_sig to png_sig_bytes in png.c and
  eliminated use of png_sig in pngwutil.c.- Moved the various png_CHNK arrays
  into local arrays.- Eliminated use of global png_pass arrays.- Declared the
  png_CHNK and png_pass arrays to be "const".- Made the global arrays
  available to applications when PNG_NO_GLOBAL_ARRAYS is not defined or
  when PNG_USE_GLOBAL_ARRAYS is defined.- Made available to applications a
  macro "PNG_USE_LOCAL_ARRAYS".
- Changed the PNG_sRGB_INTENT macros in png.h to be consistent with PNG-1.2.
- Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3
- Added PNG_EXPORT_VAR macro to accommodate making DLL's.
- Refactored the inflate/deflate support to make adding new chunks with
  trailing compressed parts easier in the future (Eric S. Raymond).
- Added iCCP, iTXt, sCAL, and sPLT support; added "lang", "lang_key", and
  itxt_length" members to the png_text structure (Eric S. Raymond, Glenn R-P)
- Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned
  offsets (Eric S. Raymond).
- Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
  PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
  macros, leaving the separate macros also available.
- Removed comments on #endifs at the end of many short, non-nested #if-blocks.
- Changed makefile.solaris to issue a warning about potential problems when
  the ucb "ld" is in the path ahead of the ccs "ld".
- Removed "- [date]" from the "synopsis" line in libpng.3 and libpngpf.3.
- Added code in pngwrite.c to work around a newly discovered zlib bug.
- Unknown chunk handling is now supported (Eric S. Raymond).
- Option to eliminate all floating point support was added.- Some new
  fixed-point functions such as png_set_gAMA_fixed() were added.
- Added new type "png_fixed_point" for integers that hold float*100000 values
- Added many parentheses, e.g., "if (a && b & c)" becomes "if (a && (b & c))"
- Added png_handle_as_unknown()
- Added chunk_list and num_chunk_list members of png_ptr.
- Define png_get_int_32 when oFFs chunk is supported as well as when pCAL is.
- Added functions png_set_read_user_chunk_fn() and png_get_user_chunk_ptr()
  for setting a callback function to handle unknown chunks and for
  retrieving the associated user pointer (Glenn).
- Added png_free_data() function.
- Added high-level functions png_read_png() and png_write_png() (ESR).
- Renamed pngdll.mak to makefile.bd32
- Cosmetic changes in pngtest.c
- Fixed pngvcrd.c bug by pushing/popping registers in mmxsupport (Bruce Oberg)
- Revised makefile.gcmmx
- Fixed a bug in pngrtran.c that improperly expanded the background color.
- Return *num_text=0 from png_get_text() when appropriate, and fix
  documentation of png_get_text() in libpng.txt/libpng.3.
- Added PNG_SETJMP_SUPPORTED, PNG_SETJMP_NOT_SUPPORTED, and PNG_ABORT() and
  "png_jmpbuf()" macros to pngconf.h, to help people migrate to the new error
  handler that's planned for the next libpng release, and changed example.c,
  pngtest.c, and contrib programs to use this macro.
- Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)
- Fixed some mistakes in the unused and undocumented INCH_CONVERSIONS functions
  in pngget.c
- Updated makefile.linux and makefile.gccmmx to make directories conditionally.
- Increased precision of rgb_to_gray calculations from 8 to 15 bits and
  added png_set_rgb_to_gray_fixed() function.
- Added makefile.bc32 (32-bit Borland C++, C mode)
- Updated references to the zlib home page, which has moved to
  freesoftware.com.
- Corrected bugs in documentation regarding png_read_row() and png_write_row().
- Renamed makefile.borland,turboc3 back to makefile.bor,tc3 as in version
  1.0.3, revised borland makefiles; added makefile.ibmvac3 and makefile.gcc
  (Cosmin)
- Added makefile.sggcc (SGI IRIX with gcc)
