I think you should just return a Layer here.

I need the LayerDelegate to draw the content of minimized home, and the layer
delegate needs to be owned by someone else. Thus I created the minimized home
layer and then returns its owner (which is actually the LayerDelegate), and
caller will own both the layer and the delegate.

Do you think this needs to be fixed?  It seems doing similarly as aura::Window.
As I reviewed aura::Window interface, I found ignore_events() field.  This could
be implemented by aura::Window with ignore_events field.

Ah, I see.
