Re: [presentation-api] Add support for allowing same-screen display (#479)

@dlibby- Sorry for the very delayed response, I was unable to spend much time on SSWG issues until recently.

If I understand correctly, the desire is to use the Presentation API to open a new browser window and have it possibly shown on the current display, or a local secondary display or remote display (which are all the possible scenarios I can think of).

If the user chooses the current display, were you assuming that the window with the presentation will be shown fullscreen on that display?

Is it important that these possibilities are all shown in the same dialog?  One solution that is possible without adding to the Presentation API is to use `window.open()` followed by [`document.requestFullscreen()`](https://fullscreen.spec.whatwg.org/#dom-element-requestfullscreen)

There's also the [Window Placement API](https://github.com/webscreens/window-placement/blob/master/EXPLAINER.md#support-requests-to-show-elements-fullscreen-on-a-specific-screen) in incubation, which would allow you to place a fullscreen document on the current display or an external display.  That may be a better fit depending on your use case.
