Part of me just wants to be evil and auto-migrate at load time. (Changes
hit disk when the user does File->Save).

on read: If version < 1.6.0, fontsize *= 1.3
on save: Save the new size

This requires us to allow floating point sizes to preserve the font
sizes exactly. (Fortunately the floating point number will terminate,
since the scale factor is 1.3, not some horrible fraction).

We could still add the "pt" syntatic sugar when saving, so the new sizes
aren't just magically inferred by looking at the file-format version
number.
