Any plans to support CSS transitions?

[Mike Hearn]

I enjoy iterating on my UI using JFX CSS and a simple hot reload feature I
added to my app, but I still have to drop back into writing code for doing
animations. In practice this means I use fewer nice animations than I
otherwise would, as perfecting them takes longer.

CSS3 has a way to denote transitions of any styleable property. Given that
JFX already has all the infrastructure, has a similar mechanism been
considered for it?
