The "position" cue setting for non-region cues positions the cue box, while for region cues it positions the text inside the region box. This will be very confusing when we harmonize the region and non-region cue rendering. We should probably disallow "position" on region-cues. If we want the offset feature, we should introduce a new cue setting called "indent" or "offset" or something else. But maybe there isn't really a use case for it. I'd say we remove "position" from region-cues for v1 and discuss "indent" for v2.
