it is you who doesn't understand a damn thing. or rather, you're
starting with a baseless assumption and reasoning from there. the
number of horizontal or vertical samples in the encoded image has
NOTHING to do with the size at which it is to be displayed. the size
to display it is determined solely by the aspect ratio. samples are
just that, samples, not pixels and certainly not square pixels.
