compiled for the update "png" package depend on it.

- ImageMagick has a new logo (contributed by Ofer Tenenbaum).
- Requests for all or part of a pixel row, or multiple complete pixel
rows, are mapped directly to the underlying image in memory, or memory
mapped from a disk file, avoiding performance-robbing pixel copying.
Requested rectangular regions which are narrower than the image width
must still be copied to a scratch space.
- Support for WBMP, Wireless Bitmap (level 0) images (contributed by
Milan Votava)
- Image sizes are limited by physical memory plus available disk space on
the machine, or the file addressing limits of the operating system,
whichever comes first. This means that if you can figure out how to
build a big enough machine (and have plenty of time) terabyte images
can be processed.
- An image cache subsystem and API are provided to map portions (as small
as one pixel or as large as the entire image) of images into memory and
to save any updates.
- Memory mapping is used to access files. This is the most efficient
access mechanism available.
- DirectColor pixels are now stored in an efficient 32-bit structure (or
64-bit when QuantumLeap is enabled).
- PseudoColor indices are now stored separately from the DirectColor
pixels (PseudoColor and DirectColor representations are still available
simultaneously).
- In-memory run-length encoding is eliminated.
- Compressed images are decompressed and compressed incrementally in
order to limit memory consumption.
- Lots of minor C API fixes and improvements.
- Cache threshold setting for setting the boundary between use of RAM or
RAM + disk when processing an image:
- Use the --enable-cache option (e.g. --enable-cache=160) to set the
compiled-in default when running the configure script.
- Use -cache for ImageMagick utilities
- Set the cache_threshold attribute in PerlMagick
- Set the cacheThreshold attribute in Magick++
- The identify utility now displays precise read-time values.
- The Win32 build environment (now called "VisualMagick") is completely
re-done and supports building both multi-thread DLL as well as static
libraries.

- 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)

avoid dependence on "gnome-libs" packages. Version 1.1.18 fixes several bugs
discovered in release 1.1.13 and invents many new features. The complete
change list contains more than 5000 lines and can't be listed here.

There's a bug in tgif-4.1.26 and tgif-4.1.27 with undoing and redoing

in tgif-4.1.28.

1) Fix a divide-by-zero bug in creating an arc (of the 2nd kind). Thanks to
Christoph Kukulies <kuku@gilberto.physik.RWTH-Aachen.DE>
for pointing out the problem.
2) Fix a crashing bug in exiting tgif. Thanks to Wolfgang Glunz
<Wolfgang.Glunz@icn.siemens.de> for pointing out the problem.
3) Fix a menuing bug in using tgif with the NetManage PC X Server. Thanks to
Wolfgang Glunz <Wolfgang.Glunz@icn.siemens.de> for pointing out
the problem.
4) Fix a bug in exporting to PDF format. With the previous implementation,
the PDF file may be generated in the wrong directory. The Tgif.PsToPdf
X default now must contain 2 "%s" substrings. The new default value for
it is "ps2pdf %s %s".
5) Fix a bug in exporting to GIF format using Print One File Per Page
when page file names are specified. Thanks to Hal Snyder
<hal@vailsys.com> for pointing out the problem.
6) The current implementation of the whiteboard has a buffer size limitation.
When the buffer size is exceeded, tgif will now print an error message
and cancel the operation that causes the buffer overflow.
