Awesome work!
Looking through the code my first concern is with the classes under org.svgweb. I'm happy to use them, but it looks like they're under an Apache License - and Reflex is already releasing under the MIT license. Do you know the author by chance? If not I can reach out to him and see if he'd allow us to redistribute it under the MIT license.
Once that's worked out, the best way to contribute would be to create a fork of the
reflex-framework project on github and start committing your contributions in the reflex.graphics package there. When you're ready just give me a ping or submit a pull request on github, and I'll be able to pull the changes right in. If you're not up for using github I can integrate contributions from the code you send me, but I want to be sure you get due credit in the version history.
Thanks - and I'm looking forward to seeing those graphics in the Reflex demos! :)
