The "rename" rule is a published synonym for the "opt" transform rule, however
only the latter is supported by cwrappers.  Change them all to "opt" rules for
consistency and to gain compatibility with cwrappers.

Update to 1.4.2. Shared library name changes from libpn12.* to libpng14.*,
so bump ABI depends.

Remove libpng.* from package, instead use buildlink to help some packages
that are looking for the library themselves instead of using pkg-config
or libpng-config.


version 1.4.2:
  Restored the macro definition of png_check_sig().
  Conditionally compile an "else" statement in png_decompress_chunk().
  Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
  Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
    more accurately what it actually does.  At the same time, renamed
    the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
  Added some "(long)" typecasts to printf calls in png_handle_cHRM().
  Relaxed the overly-restrictive permissions of some files.
  Added the "vstudio" project to replace "visualc6" and "visualc71" which
    will be removed from libpng-1.5.0.
  Demonstrate in example.c that lang_key should be initialized.
    contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
  Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
  Removed dummy_inflate.c and uncompr.c from contrib/pngminim/encoder
    in gregbook/readpng2.c
  Corrected protection of png_get_user_transform_ptr. The API declaration in
    png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
    but was left defined in pngtrans.c
  Moved declarations of umsg[] inside the proper #ifdef blocks in pngrutil.c

version 1.4.1 [February 25, 2010]

  Updated CMakeLists.txt for consistent indentation and to avoid an
    unclosed if-statement warning (Philip Lowman).
  Revised and to remove references to Y2KINFO,
    KNOWNBUG, and (Robert Schwebel).
  Revised the makefiles to install the same files and symbolic
    except for and
  Make png_set|get_compression_buffer_size() available even when
    PNG_WRITE_SUPPORTED is not enabled.
  Revised and to simplify their maintenance.
  Revised the makefiles to install a link to
  Removed png_set_premultiply_alpha() from scripts/*.def
  Revised png_decompress_chunk() to improve speed and memory usage when
    decoding large chunks, using a two-pass method suggested by John Bowler.
  Added png_set|get_chunk_malloc_max() functions.
  Relocated "int k" declaration in pngtest.c to minimize its scope.
  Folded some long lines in the source files.
  Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
  Return allocated "old_buffer" in png_push_save_buffer() before calling
    png_error(), to avoid a potential memory leak.
  Removed the cbuilder5 project, which has not been updated to 1.4.0.
  Complete rewrite of two-pass png_decompress_chunk() by John Bowler.
  Removed obsolete unused MMX-querying support from contrib/gregbook
  Removed the AIX redefinition of jmpbuf in png.h
  Define _ALL_SOURCE in, makefile.aix, and CMakeLists.txt
    when using AIX compiler.
  Removed unused gzio.c from contrib/pngminim gather and makefile scripts

Changes to Libpng from version 1.2.42 to 1.4.0 (January 4, 2010)

Libpng-1.4.0 was released by the PNG Development Group on January
3, 2010.  Important new features include support for the iTXt chunk
and a function for limiting the amount of memory that a possibly
malicious compressed chunk can consume.  Some long-deprecated functions
and features have been removed.  A new private header file that is
not visible to applications has been created, to improve our ability
to maintain binary compatibility among future libpng versions.


1. Private libpng prototypes and macro definitions were moved from
png.h and pngconf.h into a new pngpriv.h header file that is not
visible to applications.

2. Some obsolete/deprecated macros and functions have been removed.

   a. We eliminated the obsolete, unused pnggccrd.c and pngvcrd.c files
      and related makefiles.

   b. We removed the typecasted NULL definitions such as

          #define png_voidp_NULL    (png_voidp)NULL

      If you used these in your application, just use NULL instead.

   c. We eliminated the PNG_1_0_X and PNG_1_2_X macros.

   d. We eliminated the PNG_LEGACY_SUPPORTED macro.

   e. We removed many WIN32_WCE #ifdefs.

   f. We removed the functions png_read_init(info_ptr),
      png_write_init(info_ptr), png_info_init(info_ptr),
      png_read_destroy(), and png_write_destroy().
      They have been deprecated since libpng-0.95.

   g. We removed the png_permit_empty_plte() function. It has been
      deprecated since libpng-1.0.9.  Use png_permit_mng_features() instead.

   h. We removed the obsolete stub functions png_get_mmx_flagmask(),
      png_set_mmx_thresholds(), png_get_asm_flags(),
      png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
      png_set_asm_flags(), and png_mmx_supported()

   i. We removed the obsolete png_check_sig(), png_memcpy_check(), and
      png_memset_check() functions.  Instead use !png_sig_cmp(),
      png_memcpy(), and png_memset(), respectively, i.e.,

        png_check_sig(buf, 8)
        png_sig_cmp(buf, 0, 8) == 0

        png_memcpy_check(png_ptr, dest, src, length)
        png_memcpy(dest, src, length)

      and replace
        png_memset_check(png_ptr, dest, value, length)
        png_memset(dest, value, length)

   j. We removed support for global arrays to improve thread safety.

   k. We removed support for numbered error messages by default, since we
      never got around to actually numbering the error messages. The function
      png_set_strip_error_numbers() was removed from the library by default.

   l. The png_zalloc() and png_zfree() functions are no longer exported.
      The png_zalloc() function no longer zeroes out the memory that it

   m. The function png_set_gray_1_2_4_to_8() was removed. It has been
      deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
      png_set_expand_gray_1_2_4_to_8() because the former function also
      expanded palette images.

3. Several function prototypes were changed.

   a. We changed the prototype for png_malloc() from
      png_malloc(png_structp png_ptr, png_uint_32 size) to
      png_malloc(png_structp png_ptr, png_alloc_size_t size)

   b. We changed the prototypes of png_get_compression_buffer_size() and
      png_set_compression_buffer_size() to work with png_size_t instead of

4. We added some new features:

   a. We enabled iTXt chunk support by default.  This changes the png_text
      structure by adding the itxt_length, lang, and lang_key members.

   b. We added the functions png_set_benign_errors(), png_benign_error(),
      and png_chunk_benign_error().  With these, you can choose to treat
      certain normally fatal errors as nonfatal.

   c. Support for setting the maximum amount of memory that the application
      will allocate for reading chunks was added, as a security measure.
      The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
      were added to the library.

   d. We added the png_calloc() function and used it in place of
      of "png_malloc(); png_memset();" except in the case in png_read_png()
      where the array consists of pointers; in this case a "for" loop is used
      after the png_malloc() to set the pointers to NULL, to give robust.
      behavior in case the application runs out of memory part-way through
      the process.

   e. We implemented support for I/O states by adding png_ptr member io_state
      and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c

   f. We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
      input transforms.

5. Other changes

   a. We changed the names of the png_struct and info_struct members "trans"
      and "trans_values" to "trans_alpha" and "trans_color", respectively.

   b. Checking for and reporting of errors in the IHDR chunk is more thorough.

   c. We removed the trailing '.' from the warning and error messages.

   d. Direct access to png_ptr->jmpbuf has been deprecated since libpng
      version 1.0.6, and libpng now generates a warning about it.

      To avoid such warnings, change
