Changes from version 3.0:
Version 4.1.0
============
* Several minor memory leaks in error conditions have been plugged.
* New Function EGifOpen(void *userData, OutputFunc writeFunc) allows user
specified gif writing functions.
* Old copyright notices in a few source files have been updated. All library
copyrights should now reflect the copyright notice in the COPYING file.
Version 4.0.0 -- giflib
=======================
This version of the giflib library merges Eric Raymond's giflib-3.0 release
with the libungif-4.0 release to give people a binary compatible choice
between the two libraries and gives me the chance to add bugfixes to giflib
that have been incorporated in libungif.
PLEASE READ THE FILE PATENT_PROBLEMS BEFORE USING THIS LIBRARY!
Version 4.0.0
=============
Major fixes have been made to the code that handles Extensions.
Unfortunately, this causes binary incompatibility with giflib-3.0 and
libungif-3.x. However, the API is still intact. I am, however, deprecating
the use of saveImage[x].Function. Use
saveImage[x].ExtensionBlocks[y].Function instead.
Version 3.1.1
=============
The following bugs which caused SegFaults have been fixed:
* When reading gif files with extensions, DGifSlurp would violate memory.
* When closing a gif that had a local colormap, DGifCloseFile would attempt
to free the colormap twice.
* Fix a potential memory leak in DGifSlurp.
The following enhancements have been made:
* New function DGifOpen to allow specifying a user definable gif reading
function.
Version 3.1.0
=============
* Add a new function:
GifFileType *DGifOpen(void * userData, InputFunc readFunc)
to read the gif image from a user defined input function.
* A few bugfixes.
Version 3.0
===========
Changes from Eric Raymond's libgif:
* A new gif encoder that makes uncompressed gifs rather than standard,
LZW-compressed gifs. This is actually the major motivating factor behind
libungif; to provide third-party distributors a means to provide a gif
library without the patented LZW encoder.
* A new configure script to make compilation of the library on multiple
platforms easier. The package should now build shared libraries on all
platforms supported by GNU libtool.
* Removed the getarg functions from libgif. These were not part of the
public API and only used by the tools in the utils directory so I separated
them from the rest of the library.
* Fixed a few bugs in the tools in the utils directory.

need not depend on or use X. Its two X functions (capture window and
display image) are done rather well by programs available elsewhere, many
of which already support GIF (or at least PPM, which can be converted).
Also include <stdlib.h> such that the malloc() warnings go away on LP64.

Add -lX11 flags to the util Makefile to make this thing build.. How it
builds/runs on a.out is beyond me.. ELF seems to be a little more sane
in this respect.

- New, optional Makefile variable HOMEPAGE, specifies a URL for
the home page of the software if it has one.
- The value of HOMEPAGE is used to add a link from the
README.html files.
- pkglint updated to know about it. The "correct" location for
HOMEPAGE in the Makefile is after MAINTAINER, in that same
section.

informational purposes," it's not used by any of the toolchain and is
pretty much useless.

Make use of ${BSD_INSTALL_*} macros.

Remove redundant (and sometimes erroneous) comments.

have ${PREFIX}/lib in ld.so.conf instead. This ensures things
even work after a reboot.
