Drawing text on subpixel coordinates?

Would it be possible to snap to 0.5px instead of 1px verticals for retina displays? We have a object whose position animates very smoothly, and the snapping text during animation is very obvious and undesirable.

We’ve tried drawing the text to an image first, which makes the animation wonderful, but then we can’t get the text to look the same on retina devices (Text anti-aliasing looks different when drawn to image).
