I try to save the traces generated by Redex to an image. However, the
arrows between the expressions don't show up in the result.
I tried some combinations of #:x-spacing, #:edge-labels? and #:layout
to let the arrows showed up in trace, but the edges remain hidden when
I ran trace/ps. Any clue about this?

(traces R 5 #:x-spacing 400)
(traces/ps R 5 "trace-ps-image.ps" #:x-spacing 400)
