The text view subclass in this picture uses the code I

sure why. There are also other minor drawing glitches.
No pun intended, but it looks to me like the artefacts are to do with
rounding errors. The pixilation of curves can differ depending on
exactly where the curves start and end relative to pixel boundaries.
