Ah, makes sense. Wasn't there once upon a time a CSS draft that let
you specify how replaced elements should stretch in situations like
this? So you could choose if it should zoom-to-fit (like it sounds
like <video> does) or stretch-to-fit (like <img> does), zoom-to-fill
as well as a few other things. I can't seem to find it though...

I guess my point is, can we let CSS deal with this? If it indeed needs
to be dealt with.
