I didn't realize there was an actual draft that defined that. But you're right: What I'm looking for is something inheritable that can double the number of hardware pixels per 'px' used in each dimension for each 'zoom' level multiplier (it doesn't have to be called 'zoom' or have anything to do with existing zoom implementations). But if set to '1', it would revert to normal pixel resolution. 

I thought 'zoom' worked like that; I stand corrected.
