I'm reading this article on the PixelRatio class in React Native. It says "iOS tries to be as faithful as possible to the user value by spreading one original pixel into multiple ones to trick the eye".
What does this mean? Does it mean that if you set something to be 1.9 in size, it will "spread" the element to be 2 pixels? If so, would it round 1.4px down to 1px?
