:) I think they may have used some ideas :) but we didn't participate in the process. Back ten I suggested to use Cacio (and improve upon it), but I didn't receive any follow up.

Cacio is a Java2D backend in the end, I don't know if it works with JavaFX, but it would be nice to give it a try, maybe you could help us on that? :) Cheers, Mario --- pgp key: http://subkeys.pgp.net/ PGP Key ID: 80F240CF Fingerprint: BA39 9666 94EC 8B73 27FA FC7C 4086 63E3 80F2 40CF http://www.ladybug-studio.com IcedRobot: www.icedrobot.org Proud GNU Classpath developer: http://www.classpath.org/ Read About us at: http://planet.classpath.org OpenJDK: http://openjdk.java.net/projects/caciocavallo/ Please, support open standards: http://endsoftpatents.org/
