Yeah, it must have, but it's too bad we did not make that a quirk,  
because surely there can be sub-(w3c)pixel positioning on super hi-res  
displays.

Memoization is definitely a can of worms, but surely if you are  
memoizing, you memoize on the actual input value of the method, not on  
some canonicalized value?
