= Spec =
https://w3c.github.io/presentation-api/

= Summary =
This is implementing the receiving side of the API in order to allow a
web page to be presented and interact with the presenting web page.
Chrome will support presentation pages in the 1-UA mode (rendered
locally offscreen).

= Motivation =
This is implementing the missing bits from
https://www.chromestatus.com/feature/6676265876586496. It will allow
regular websites to be presented using Chromium.

= Compatibility Risk =
Firefox: In development
Edge: No public signals
Safari: No public signals
Web developers: No signals

Ongoing technical constraints? None.

Will this feature be supported on all six Blink platforms (Windows, Mac,
Linux, Chrome OS, Android, and Android WebView)?
Android will not have support before L because of OS limitations.
Otherwise, same as the general Presentation API: all platforms except
WebView.
