Agree. Not sure where I copied that from, but splitting in width/height
definitely makes sense.
Also, might even be worth considering adding something for 3d scene
files, but that's probably future talk for the next few years ;)

I was originally using seconds, but then decided that seconds are too
low accuracy for properly displaying a slider or progress bar when the
audio/video is just a few seconds. I can't imagine any usecase where
flick accuracy would be needed, but if there are, I'd rather like to
move those in a separate field. The <length/> is mostly for something
that can actually be displayed to normal users, and flick unit accurate
numbers certainly can't, except when rounded to millisecond accuracy or
less ;)
