In the old navigation model, we set focus to a node, and checked to see if that node was still valid (could have changed since we built the navigation cache). Then we sent a message back to the UI thread to tell it to draw the ring differently. In the new model, we are essentially moving a mouse, so we do not concern ourselves with whether the node is valid. Removed all the code for passing the message to the UI thread and calling into native. Needs a change to external/webkit to work properly.
