Hi, again.
I have been playing around a bit more with this library. However I just realized that you don't have defined license anywhere. This is something I need to know before continuing to work on this, since I'm planning to use it with a commercial project. We were previously using XSpriter, but your work has some features that are missing from it and much better codebase.
I also found more bugs and missing features and have patches for those. Bigger than one liners this time. I tried to create an account at assembla, but it doesn't let me fork and I don't want spend time figuring out why. Tell me if you have preferred way of receiving patches. I/You could put it up at CodePlex or GitHub if the license allows and you are fine with it.
