nit: "the display's root ServerWindow"? and "for the |new_size|", fix the other
mention of |size| to |new_size|.

Changed method otherwise.

+  // new |size| if necessary. |size| is in physical pixels.
+  void UpdateRootWindowSize(const gfx::Size& new_size);

Would it make sense to keep this as OnViewportMetricsChanged, and just have the
impl use its pixel_size?

Hmm, we're not using the rest of the values now.. but we definitely need them in
the future. Changed back.
