Summary 0007223: [RFE] GIFReadWriter and Animated Gifs can be done better.
Description GIFReadWriter had a serious bug affecting the reading of animated gifs.

That has been diagnosed and patched in 0007210.

In the course of looking into that problem, I learned enough about gifs to wish for a more elegant reader.

Additional Information The gif spec just about describes how to structure a program.
Also the current reader/writer has a high code smell due to too many ivars and methods with high temp var counts as well.

I am sure some of the justification for that was the need to coax speed out of the reader.

I think with a second pass over the code some simple resturcturing could make it more robust and compartmentalized.

I didn't want to burden the previous report with that task.

So I have started this one to contain the more extensive work.
