Another thing that we need is some way to determine what the device

tell that it's 1:1 -- you would have do do a fillRect(width-1, height-1,
1, 1),; then getImageData(width-1, height-1, 1, 1) and see if they
match. Conceivably you could do this multiple times to estimate the
ratio, but it would be non-trivial.
Why would you need that data?
The moment people start using getImageData() as storage mechanism (which
they will if browsers do not fix their data: image origin stuff) you'll
have a problem with this if the application is accessed through different
devices that have different ratios. I suspect though that given that
Firefox has a 1:1 ratio sites will simply rely on that...
