Re: video size when aspect ratio is not 1

I think the classic normative algorithm is to make the narrow 
dimension of the pixels match the pixel width on the display, and 
have the larger dimension occupy 1.x pixels on the display, as that 
preserves all the pixel data in the original.

i.e. if the video is 10x10 pixels and the pixels are 12/10 (taller 
than they are wide), then present in a 12x10 pixel-sized area.
