giflib -- A library for processing GIFs

File Release Notes and Changelog

Release Name: giflib-4.1.4

Notes:
Version 4.1.4
=============
This version fixes some bugs with deallocating ColorMaps.  Fix building on
several platforms.  Fix x86_64 builds to not hang the encoder.

* Fix several areas in decoding where we removed a ColorMap from our GifFile
  but didn't set the pointer to NULL.  This could lead to double free's of
  the ColorMap.
* Fix a bug in dev2gif.c where we redefined some gl types incorrectly.
* Fix a bug in the gif LZW encoder that was triggered on modern 64 bit
  platforms.
* Fix building on Windows.  Note -- there has been one API changing event for
  Windows (renaming DrawText to DrawGifText.)  This should have conflicted with
  Windows API and therefore caused the builds to fail previously.  If you had
  it working with DrawText before, apologies, you'll need to change to
  DrawGifText in your code.  This only affects Windows.
* Add support for building on The Game Boy Advance.  Note: Due to the GBA's
  limited memory, the API for the GBA uses short's in many places where the
  other platforms use ints.  This shouldn't affect anyone unless you've
  been able to get an older version of the code to run on GBA and want to
  start using this version instead.  A recompile of your dependent code
  will be necessary in this case.

    Changes from Lennie Araki:
    * gba/giftest.mak: Prefix the names of defines for the GBA build with _GBA.
    * lib/dgif_lib.c, lib/gif_lib_private.h, lib/gif_err.c:
      - When Compiling for Game Boy Advance, file functions are not needed so
        exclude DGifOpenFileName(), DGifOpenFileHandle(), DGifSlurp(), and
        PrintGifError().
      - On Game Boy Advance we need to reduce memory usage.  Change values to
        short int where appropriate.
    * lib/gif_lib.h:
      - Handle te GBA changes by defining GifPrefixType and GifWord to int
        unless compiling on GBA.  Then use unsigned short and short
        respectively.
      - Fix a problem with the API on _WIN32.  DrawText conflicts with the
        Windows API.  Call it DrawGifText instead.
