I've update msf_gif.h from v2.1 to v2.2.
v2.2 is backward-compatible with v2.1 and adds the following features:
- support for encoding transparent gifs
- a set of functions to encode directly to a file, for use on memory-constrained platforms
- support for passing in pixels in BGRA byte order
- improved memory footprint and allocator usage
- improved documentation
Additionally, all the code and data I use for testing is now included in the repository, which should make it possible, and hopefully easy, for contributors to use.
