Another thing, if I as a website developer find a video that was
encoded with the wrong pixel ratio, wouldn't the simplest, and most
intuitive, way to fix it be to simply set a width and height on video
until it looked approximately correct? Yes, it's a hack, and should
not discouraged, but so is pixelratio.

(haven't followed this discussion in detail so appologies if
width/height has been disqualified already)
