looks like when we change from image wallpaper to solid background color, we
wont have an fade in animation. Not the other way around.

And this seems specify to solid color. Could you please reword the comment?

I think my comment precisely reflects what this function does. It sends
animation finished notification event. But it is true that it is used for solid
colors only. But I think this comment could be in SetColorLayerForContainer but
to me it is obvious and won't add readability to the code.

+  void NotifyAnimationFinished();
+
   // Can change at runtime.
   bool locked_;
 
   BackgroundMode desktop_background_mode_;
 
   SkColor background_color_;
 
   // The current wallpaper.
   scoped_ptr<WallpaperData> current_wallpaper_;
 
   scoped_refptr<WallpaperOperation> wallpaper_op_;
 
   base::WeakPtrFactory<DesktopBackgroundController> weak_ptr_factory_;
 
   DISALLOW_COPY_AND_ASSIGN(DesktopBackgroundController);
