Re: [visualViewport]: Proposal and RFC

I've added ViewportAPI to the TPAC agenda
<https://wiki.csswg.org/planning/tpac-2016?&#proposed-agenda>.  If desired
I can give a short presentation and lead a discussion on some of the
issues.  But I don't have all the context Yash and David do, so we may want
to do most of the detailed API debate on GitHub where they can participate.
