I don't think it's necessary: the builder uses `addTestWindow` under the hood. It's the builder that requires documentation.

In fact, the entire class requires a bit of TLC for documentation. I even wrote some after Lawrence @lawrence-andrew created the first version of `PassFailJFrame` but I never finished it. Even this part was implemented nearly a year ago.

I plan to create a wiki page on the [client-libs wiki](https://wiki.openjdk.org/display/ClientLibs) to describe creating manual tests with `PassFailJFrame`.
