PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism

Moved version 1.4.0 back into beta.
version 1.4.0beta88 [October 30, 2009]
Revised libpng*.txt section about differences between 1.2.x and 1.4.0

Removed all remaining WIN32_WCE #ifdefs except those involving the

Revised libpng*.txt to describe differences from 1.2.40 to 1.4.0 (instead
of differences from 1.2.41 to 1.4.0)
version 1.4.0beta93 [November 7, 2009]
Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
PNG_ALLOCATED macros to detect deprecated direct access to the
png_struct or info_struct members and other deprecated usage in
applications (John Bowler).
Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
to prevent warnings about direct access to png structs by libpng
functions while building libpng. They need to be tested, especially
those using compilers other than gcc.
Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
They should work but still need to be updated to remove
references to pnggccrd.c or pngvcrd.c and ASM building.
Added README.txt to the beos, cbuilder5, netware, and xcode projects warning
that they need to be updated, to remove references to pnggccrd.c and
pngvcrd.c and to depend on pngpriv.h
Removed three direct references to read_info_ptr members in pngtest.c
that were detected by the new PNG_DEPSTRUCT macro.
Moved the png_debug macro definitions and the png_read_destroy(),
png_write_destroy() and png_far_to_near() prototypes from png.h
to pngpriv.h (John Bowler)
Moved the synopsis lines for png_read_destroy(), png_write_destroy()
png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3.
version 1.4.0beta94 [November 9, 2009]
Removed the obsolete, unused pnggccrd.c and pngvcrd.c files.
Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
Removed dependency of pngtest.o on pngpriv.h in the makefiles.
Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
version 1.4.0beta95 [November 10, 2009]
Changed png_check_sig() to !png_sig_cmp() in contrib programs.
Added -DPNG_CONFIGURE_LIBPNG to contrib/pngminm/*/makefile
Changed png_check_sig() to !png_sig_cmp() in contrib programs.
Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
Changed pngminim/*/gather.sh to stop trying to remove pnggccrd.c and pngvcrd.c
Added dependency on pngpriv.h in contrib/pngminim/*/makefile
version 1.4.0beta96 [November 12, 2009]
Renamed scripts/makefile.wce to scripts/makefile.cegcc
Revised Makefile.am to use libpng.sys while building libpng.so
so that only PNG_EXPORT functions are exported.
Removed the deprecated png_check_sig() function/macro.
Removed recently removed function names from scripts/*.def
Revised pngtest.png to put chunks in the same order written by pngtest
(evidently the same change made in libpng-1.0beta54 was lost).
Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
version 1.4.0beta97 [November 13, 2009]
Restored pngtest.png to the libpng-1.4.0beta7 version.
Removed projects/beos and netware.txt; no one seems to be supporting them.
Revised Makefile.in
version 1.4.0beta98 [November 13, 2009]
Added the "xcode" project to zip distributions,
Fixed a typo in scripts/pngwin.def introduced in beta97.
version 1.4.0beta99 [November 14, 2009]
Moved libpng-config.in and libpng.pc-configure.in out of the scripts
directory, to libpng-config.in and libpng-pc.in, respectively, and
modified Makefile.am and configure.ac accordingly. Now "configure"
needs nothing from the "scripts" directory.
version 1.4.0beta100 [November 14, 2009]
Removed ASM builds from projects/visualc6 and projects/visualc71
Removed scripts/makefile.nommx and makefile.vcawin32
Revised CMakeLists.txt to account for new location of libpng-config.in
and libpng-pc.in
Updated INSTALL to reflect removal and relocation of files.
version 1.4.0beta101 [November 14, 2009]
Restored the binary files (*.jpg, *.png, some project files) that were
accidentally deleted from the zip and 7z distributions when the xcode
project was added.
version 1.4.0beta102 [November 18, 2009]
Added libpng-config.in and libpng-pc.in to the zip and 7z distributions.
Fixed a typo in projects/visualc6/pngtest.dsp, introduced in beta100.
Moved descriptions of makefiles and other scripts out of INSTALL into
scripts/README.txt
Updated the copyright year in scripts/pngwin.rc from 2006 to 2009.
version 1.4.0beta103 [November 21, 2009]
Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt
Align row_buf on 16-byte boundary in memory.
Restored the PNG_WRITE_FLUSH_AFTER_IEND guard around the call to png_flush()
after png_write_IEND(). See 1.4.0beta32, 1.4.0beta50 changes above
and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES. Someone needs this
feature.
Make the 'png_jmpbuf' macro expand to a call that records the correct
longjmp function as well as returning a pointer to the setjmp
jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
(John Bowler)
version 1.4.0beta104 [November 22, 2009]
Removed png_longjmp_ptr from scripts/*.def and libpng.3
Rebuilt configure scripts with autoconf-2.65
version 1.4.0beta105 [November 25, 2009]
Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535() to accomplish
alpha premultiplication when PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
Changed "/255" to "/255.0" in background calculations to make it clear
that the 255 is used as a double.
version 1.4.0beta106 [November 27, 2009]
Removed premultiplied alpha feature.
