This project uses the following include files:
- 7seg.h
- Nothing interesting here, just a function prototype.
- gif.h
- This contains the GIF compressor's work area data structure, gif_context_t.
The work area is used for compressing the bitmap to GIF format.
Since the topic of GIF compression is beyond the scope of this book I won't go details.
All of the global variables that were present in the original GIF encoder were
gathered up and placed into a data structure.
