We already have durationchange. Duration is metadata. If we want to  
support changes to width/height, and the script is interested in when that  
happens, maybe there should be a dimensionchange event (but what's the use  
case for changing width/height mid-stream?). Does the spec support changes  
to text tracks mid-stream?
