| Yes, you can centralise by working out the height of the text
| (there seems to be a surprising difference in heights of
| fonts for the same point size - but maybe that is my optical

| with `-gravity center'. But the latter centres on the height
| of the entire image, not the label area.

Create the label, and append it with centering.
And yes this is another 'hack'.
Real justified append (left, right, center) has been on the ToDo list
for a long time.
