With anti-aliased fonts we need a more fine-grained horizontal position
than a single pixel. 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.

Sometimes the console must be rotated. Add a driver which supports rotating
the text clockwise to 90, 180 and 270 degrees. This can support devices
where the display is rotated for mechanical reasons.
