This comment is accurate, though it was a bit confusing to me since this class
doesn't directly derive from View (indeed, this is a few steps up the class
hierarchy).

Good point.  I'll change these.

+                mojo::Array<uint32_t> children_needing_layout,
+                const OnLayoutCallback& callback) override;
+
+  void UpdateScene();
+  void DrawContent(SkCanvas* canvas);
+
+  mojo::Size size_;
+
+  DISALLOW_COPY_AND_ASSIGN(ShapesView);
+};
+
+}  // namespace examples
