If @racket[edge-labels?] is @racket[#f], no edge labels are
drawn. Otherwise, they are.

If @racket[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 @racket[dc<%>] object's font.

If @racket[cache-arrow-drawing?] is @racket[#f], then the arrows in the snip
are not cached in a bitmap (to speed up drawing when the mouse moves around).
Otherwise, they are.

}

This mixin overrides many methods to draw lines between
@racket[graph-snip<%>] that it contains.}
