Re: video aspect use case

We want to be very careful here that we don't go all the way of  
fitting content to the available screen space, that should be left to  
composition languages. SMIL has umpteen ways to clip/scale/extend  
media (zoom x/y independently, zoom coordinated and fill destination  
area, zoom coordinated and make sure whole picture is still visible,  
zoom coordinated but never enlarge, probably a few more I've forgotten  
about).

My opinion: if we do aspect at all we only do the one use case of  
converting between 16x9 and 3x4. (And anything that comes "for free"  
if we do that).
