	(mln::internal::bool_proxy): New class.
	(mln::internal::unbool<V>:): New trait class.
	(mlc_unbool): New (local) shortcut macro.
	(mln::internal::data< complex_image<D, G, V> >::values_):
	Change type from metal::vec< D + 1, std::vector<V> >
	to metal::vec< D + 1, std::vector< mlc_unbool(V) > >.
	(mln::complex_image<D, G, V>::lvalue)
	(mln::complex_image<D, G, V>::rvalue):
	Adjust typedefs.
	(mln::complex_image<D, G, V>::values() const):
	Adjust method.
	(data< complex_image<D, G, V> >::data):
	Adjust ctor.
	Simplify precondition.
	(complex_image<D, G, V>::complex_image(const p_complex<D, G>&)):
	Simplify.
	(init_(image_t, complex_image<D,G,V>&, const complex_image<D,G,W>&)):
	Depend on model's domain instead of its values to compute the
	number of n-faces.
