Why don't things less than half a device pixel round to zero (at least for used value)? That is what I would expect (unless you were going to simulate a 60th of a pixel by averaging the colors of the subpixels, the way anti-aliasing or image size interpolation does). I assume you have a perfectly logical reason, but I cannot guess what it is.
