Graphviz: reducing margin on skewed polygon node

Question

I want to use a skewed polygon (aka parallelogram) on Graphviz, the problem is there is too much space between parallelogram border and it's text.

digraph G {
    poly1[margin=0, width=0, height=0, shape=polygon, label="This is a polygon\nwithout skew"]
    poly2[margin=0, width=0, height=0, shape=polygon, label="This is a polygon\nwith skew", skew=0.3]
}

This is the result of previous code:

As you can see, as soon I set a skew value (ìn this case skew=0.3) the polygon's interior margin increases a lot. Setting margin=0, width=0 and height=0 does not solve the issue.

Is there a way to remove the polygon's interior margin?

Answer 1

There's a way, but it ain't pretty:

digraph G {
    poly1[margin=0, width=0, height=0, shape=polygon, label="This is a polygon\nwithout skew"]
    poly2[margin=0, width=1.8, height=0.46, shape=polygon, fixedsize=true, label="This is a polygon\nwith skew", skew=0.3]
}

Adding fixedsize=true and specifying the node's width and height (by trial and error) yields this:
