I added them while trying to get the vertical wrapping labels
doing w4h.

The intention was to ensure the minimum size in the backwards
request mode. A horizontal label likes to be asked its width but
returns an invented value for the height; so when asked for its
desired height it returns the desired heights for the minimum width.

It seems the required_rect in this case is rendered with the minimum
width making the required_rect.height be the correct value anyway.

In this case we should at least do:
   natural = MAX (minimum, natural);

To make sure the label is responding to the api correctly.

Great, thanks.
