[whatwg] Full screen for the <video> element

[Dave Singer]

If we don't have a way for content to request full screen (markup, 
script, whatever), I'm OK with that.  But I think that we should say 
why we left it out, in the spec., and not be silent.  Otherwise we'll 
merely see browser makers doing their own extensions to do it anyway, 
and then we'll also have non-interoperable methods as well as the 
security issues...
