[x3d-public] CSS st5yle usage for Routes [was: id attribute proposal]

[John Carlson]

We can look at draggables with css and classes to get an idea of how to do
things every frame.  I am not sure of the IP on that, but I've seen it in
jquery and meteor.  I am not sure if it's in a published standard.  I am
also not sure about dragging multiple objects...sounds like xerox or apple
IP.  Oh well.

While this is not hard to do (for example jQuery does this), it can cause considerable overhead if you have to check the entire scene graph for matching nodes on every animation step.
