Each of these functions builds a lazy layout specification for the given
layout function, to be used with layout_() or add_layout_(). The
specification is only evaluated when the layout is actually computed, so it
can be combined with layout modifiers such as component_wise() or
normalize().
as_bipartite(), as_star() and as_tree() wrap layout_as_bipartite(),
layout_as_star() and layout_as_tree() respectively. in_circle(),
nicely(), on_grid(), on_sphere() and randomly() wrap
layout_in_circle(), layout_nicely(), layout_on_grid(),
layout_on_sphere() and layout_randomly(). with_dh(), with_fr(),
with_gem(), with_graphopt(), with_kk(), with_lgl(), with_mds(),
with_sugiyama() and with_drl() wrap layout_with_dh(),
layout_with_fr(), layout_with_gem(), layout_with_graphopt(),
layout_with_kk(), layout_with_lgl(), layout_with_mds(),
layout_with_sugiyama() and layout_with_drl().
