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.
