We reuse PositionOrAuto here, and let "auto" represent the situation when the author omits "at <position>" because it has a special meaning. https://drafts.fxtf.org/motion-1/#valdef-ray-at-position Note: No need to update css/motion/parsing/offset-path-parsing-valid.html because Blink added some to the upstream repo already.
