Add scrolling tree logging to RemoteLayerTree output
Comment 1 Simon Fraser (smfr) 2014-05-06 20:55:34 PDT 
Sample output:
  (scrolling state tree
    (has changed properties 1)
    (has new root node 0)
    (node 3
      (type frame-scrolling)
      (children
          (node 4
            (type overflow-scrolling)
            (scroll-position (0,157))
            (children
                (node 5
                  (type sticky)
                  (sticky position-at-last-layout width=0 height=-113)
                  (layer-position-at-last-layout (0,447))))))))

I think there should be a dash between sticky and position.
