Characters can be positioned to start part-way through a pixel, with anti-aliasing (greyscale edges) taking care of the visual effect. To cope with this, use fractional units (1/256 pixel) for horizontal positions in the text console.

At present the name is formed from the driver name with a suffix indicating the rotation value. It seems better to name them sequentially since this can be controlled by driver order.
