           Summary: [WebVTT] Need to be able to move group of cues to a
                    different on-screen location

Sometimes when you render captions on a video, there is burnt-in text appearing
at exactly the location that your captions are rendered. So, you want to be
able to move the cues that are currently rendered in that location as a group
to another on-screen location while that text is shown and back to the original
position again after this.

This can be the case both for pop-on or roll-up captions, e.g. with two cues,
where they are both rendered bottom middle, then together moved to top middle
to avoid text, then one disappears and the next cue is rendered at top middle,
then these two cues move back to the original position bottom middle as the
burnt-in text disappears.

The moving of the group of captions' rendering location should be possible in
WebVTT. It is also a feature that should be possible interactively in the UA
after rendering.
