I have continued to work on this code. It is more of a hobby for me, and it comes in waves when I get inspired. Please sign up to the releases email forum at: https://groups.google.com/forum/#!topic/spritelibrary That is the quickest way to be notified when I make enough changes to warrant a new release. I do semi-regularly fix things that remain in the development branch until they are stable, or I have enough of them to go through the effort of making an actual release.
If you have questions, please post them on the above forum. I will answer as I can. And, hopefully other SpriteLibrary users will also be able to help.
This is the wiki. There is a lot of basic information here.
