New description:
In #12993, Christian had the great idea to use the rank function (for a
ranked poset) to compute the heights when plotting a poset.
For example, we would want the following poset
{{{
sage: P = Poset(([1,2,3,4],[[1,4],[2,3],[3,4]]), facade = True)
sage: P.plot()
}}}
to be plotted like this:
{{{
o
/ \
o o
/
o
}}}
