I didn't think that sounded right, but I couldn't figure out why. This
sounds an awful lot like how LCD laptop screens work, where they look fine
if you set the screen size according to the actual physical pixelation of
the screen, but if you go bigger or smaller it gets all wonky as it tries to
average the colors across the pixels.
