[webvtt] Wide Review Comment 2017: position and size reference is video or video viewport?

nigelmegitt has just created a new issue for https://github.com/w3c/webvtt:

== Wide Review Comment 2017: position and size reference is video or video viewport? ==
Copy/paste from https://lists.w3.org/Archives/Public/public-tt/2017Sep/0080.html - raising as an issue for tracking/disposition purposes.

In some places sizes and positions are defined relative to the video viewport; in others the video itself. This is likely to cause some confusion or mis-alignment when the two are not the same (e.g. a 16:9 aspect ratio video is displayed in a 14:9 viewport) and creates an authoring problem. For example the cue box size is relative to the video but the cue box line is relative to the video viewport (both defined within section 3.1).
