The biggest problem is that you would have to define the behaviour in
a fairly counterintuitive way
new ImageData(400, 400) would not necessarily result in an ImageData
object with width=400, height=400
as a system with a non-1:1 css to device pixel ratio.

Part of my commentary was on a misunderstanding of the spec sorry :(
That said, what do you mean by using getImageData as a storage
mechanism?
