there's a lot of windows. can we always prefix with Native or Foreign for
clarity throughout this CL?

We're always referring to the foreign window in this API. Let me know what you
think about the changes I made to these functions. If a "Foreign" prefix is
needed I can add that too.

+  void SetWindowVisible(bool visible);
+
+  // Called when window contents have changed.
+  void OnWindowContentsChanged();
+
+  // Called when window has been destroyed.
+  void OnWindowDestroyed();
+
+ private:
+  void CreateTexture();
+  void OnTextureCreated(scoped_refptr<ForeignWindowTexture> texture);
+
+  scoped_ptr<views::View> contents_view_;
+  scoped_ptr<aura::Window> window_;
