Comment (by reimar):
I'd really like to see how you would scale a video by a factor 3 and
encode it at 320x240 resolution without cropping after scale.
That is a case that is completely impossible, but in general the border
pixels will look different between both orders, and the one with crop
first is only correct when croppping borders. When cropping content (e.g.
to change aspect) cropping after scale will give more accurate results.
