I believe Chrome will rescale it to whatever you want, whereas Firefox 
will fail with OverconstrainedError, reflecting the fact that no camera 
on the machine has a native 160x90 mode. Both are to spec btw, but which 
one honors the intent of the spec?

See my other post right now about discovery and arbitrary scaling being 
mutually exclusive.
