If edge-labels? is #f, no edge labels are
drawn. Otherwise, they are.
If edge-label-font is supplied, it is used when drawing the labels on the edges. Otherwise, the font is not set before drawing the labels, defaulting to the dc<%> object’s font.
This mixin overrides many methods to draw lines between
graph-snip<%> that it contains.
