[whatwg] Proposal for a tab visibility API

[Ian Hickson]

Back in December there was a discussion about a tab visibility API.

I haven't added this feature to the HTML specification at this time, for 
a couple of reasons: first, it seems like something we'd really want to 
have implementation experience before deciding on a specific API, and 
second, it seems like something that belongs more in the CSSOM API spec 
than in the primarily media-independent HTML spec.

I have saved all the feedback on the topic in case anyone is interested in 
working on a specification for this.
