[whatwg] <video><overlay> for captions/subtitles/etc

[Philip Jägenstedt]

As part of the work in the W3C HTML Accessibility Task Force I have  
proposed a new <overlay> element to handle several use cases which are  
currently not solved by HTML5 <video>.

Certainly we shouldn't be adding this to HTML5 at this point, but I think  
HTML6 and beyond is something the WHATWG should be involved with.
