If polling is what you're doing, I guess the reason for involving a 
video element is that getSettings is not yet implemented (there the 
width and height is available).

The (WhatWG flavor at least) video element also has the resize event 
which sounds like what you'd want to use to avoid polling if there is no 
event on the track that can be used.

I agree that a resolutionchanged/resize event could be quite useful in 
certain situations, but can't overconstrained solve some of the cases? 
Put a mandatory constraint on height 90; if this is not met there will 
be an event fired.
