I hadn't seen the applyCSS conversation, but looks like it was contained deep
in a node validation thread:
http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/008549.html
Looks like the request is already covered in RT-21206 as pointed out by David.
Looks like the feature will show up some time post-Java8, which is why there is
nothing on Node now.
For now, I stick with Kevin's node snapshot workaround:
// create a dummy scene so layout and CSS will work
new Scene(new Group(node));
node.shapshot(...)
Thanks for the info!

I could have sworn we have already had this conversation and we had a name
picked out and everything (maybe it was applyCSS?). I don't see it in Node yet
though.

There is https://javafx-jira.kenai.com/browse/RT-21206, which I've just edited
to be public.
