Two questions about :visible-border

Hello lispworkers,

1. Does anybody know about
     :visible-border :outline ?
This is mentioned in examples/capi/elements/text-input-pane.lisp. I do not
see any difference from
     :visible-border :default
 in LWW 4.4.

2. Is it possible to make
     :visible-border nil
 work for capi:text-input-choice and capi:option-pane?
