There likely is less WebGL content that would be broken if you chose to return device pixels here, but for consistency CSS pixels seems like the right thing.
In general I'm not a fan of auto-doubling the backing store. It gets very confusing. The user needs to detect a bunch of things before knowing what will happen. With WebGL it gets even more tricky - what should MSAA do? Produce 16x the backing store?
Yep, these are all very good points. There is some urgency to these questions - both for 2d canvas, 3d canvas and img elements.
