q:
  1) is layer_ guaranteed to be non-null? OR
  2) are we guaranteed clients won't call isOrphan() when layer_ is null? (i.e.,
doing so would be programmer error)

yes layer_ is not null. it is set to a valid pointer in the constructor.
Layer::Create() always returns a new layer. (see the use of layer_ unguarded in
the current destructor).
