There are a few problems with using this script with Octave.

(1) The script sets the units property to "pixel" instead of "pixels". 
Apparently Matlab will match that correctly for a radio-property?

(2) The script also assumes that the ticklabels are stored as character arrays. 
Since Matlab permits this property to be be character, numeric, or cells, this 
is a bug for the script.

(3) The script relies upon extent and position info for the axes labels. 
Unfortunately, the gnuplot backend does not provide this info.

(4) The script requires that the text can be rotated. The FLTK backend only 
supports text rotation in increments of 90 degrees.

Perhaps a bug report should be filed for (1).

As part of the motivation for the OpenGL backend was to eliminate problems such 
as (3), I don't expect anything to be done about that.

The non-general rotation of the text objects will eventually be resolved by 
adding the functionality to FLTK or by use of another OpenGL backend (Qt?).
