Replying to [comment:9 hamish]:
> I don't know if it is possible to get the right-hand coordinate of a PS
pseudo-text box when the text is left-justified. I do not wish to right-
justify those labels.
You can use the `stringwidth` operator to obtain the width of a string
(the distance that the current point will move if you `show` the string).
If the string is short, you can obtain the bounding box with a combination
of the `charpath` and `pathbbox` operators (if the string is long,
`charpath` may overflow the maximum path length).
