-  Layout: the RenderObject needs a relayout after the style change
-  Visible: The change is visible, but no relayout is needed
-  NonVisible: The object does need neither repaint nor relayout after
-       the change.

-  optimisations are unimplemented, and currently result in the
-  worst case result causing a relayout of the containing block.
