I have prepared a summary of the changes that we have discussed in this
thread and rebased the corresponding changesets onto the current
revision of octave. I think that the first two of the attached
changesets should be adopted independently of the the third one.

1. The first changetset sets the default axis labels size from 12 to 10.

2. The second changeset permits the user to manually set the position
and rotation of the axis labels and title in the fltk backend.

3. The third one fixes:
> px = get (xlabel ('hello world'), 'position')
> px =   0   0   0
This error also occurs with the current octave version, so is not
related to the previous two patches, so the adoption of the third patch
shouldn't be a blocker for the first two.
