need mechanism to mark nodes as "layout roots" such that layout changes below them don't trigger layout beyond the root

      Currently requestLayout() will recurse up the hierarchy, marking all ancestors with needsLayout=true.
      however sometimes certain nodes in the scene graph (e.g. scrollpane, some controls) do not want
      layout requests underneath them percolating up beyond because the graph above should be unaffected
      by the changes within that branch. The current system causes a lot of unnecessary layout processing.

      We need to alter our requestLayout mechanics to support this concept.
