Here's a c++ implementation of your code to share

Hi Charlie,

I've implemented a c++ class based on this project, `gif-h`.

You can find it [here.](https://github.com/fyngyrz/gifanimcplusplus) Feel free to link to it, etc.; I have of course linked my project to yours.

Also, [credit is given here.](http://ourtimelines.com/itdoc/credits.html)

Thanks so much for your work. Much appreciated!
