Missing ::layout() const in certain Engines

[Richard Guenther]

Hi!

Is there something why f.i. Engine< .. IndexFunction .. > or
Engine< .. ApplyFieldStencil<> .. > dont have a ::layout() const
method? This prevents me from f.e. writing

  a(I) = stencil1(stencil2(b))(I);

(doesnt compile, complains about missing ::layout()). If I just add

  inline DomainLayout<Dim> layout() const { return DomainLayout<Dim>(domain_m); }

to src/Field/DiffOps/FieldStencil.h::Engine<Dim, T, ApplyFieldStencil<Functor, Expression> >
this compiles and seems to work as expected (need to do a formal testcase,
though).

Any hints to something I'm missing?

Richard.
