Re: [presentation-api] Same-screen presentation (#476)

Thanks @anssiko - having a Picture-in-Picture surface sounds like a very interesting idea! However, I probably wasn't clear enough in my initial post as to what PowerPoint is trying to accomplish.

Today in PowerPoint's desktop application, if you click on the 'slide show' button in the bottom right corner, you will see the slides in fullscreen. If there is a second screen, the slides will be fullscreen on the second screen, and the original view will be changed to a notes view. If there is only one screen, the slides show up as fullscreen on the one screen, and the original view is not changed at all (though it is not visible unless you, e.g. alt-tab to switch back to it).

They are interested in supporting the latter case via PresentationAPI, but currently no user agent that I'm aware of will provide a choice of the current screen.

Based on your response, it sounds like this is not disallowed by the spec, so perhaps existing implementations could change to support this (would love to hear others' takes on this). Or perhaps we could consider adding an optional dictionary to PresentationRequest start() and getAvailability() to hint to the UA that this behavior is desired?
