Follow-up Comment #46, bug #45494 (project octave):

The attached simple patch is enough to have Octave use the native gl2ps pdf
output for "-dpdf" and "-dpdfwrite". Try 


clf ()
sombrero
colorbar
print /tmp/foo.pdf
open /tmps/foo.pdf


As you can probably see:
* The text labels are misplaced. This bug has been solved in the latest dev
version of gl2ps [1]
* If you are using a version of gl2ps  < 1.4, the image of the colorbar is
missing [2].

On linux we can't expect that lts distributions will ship with gl2ps 1.4.0
(don't speak about 1.4.1 which will have text alignment fixed) before a few
years from now. So I don't think it is an option to do the switch *unless*
Octave itself includes its own copy of gl2ps as it used to do. 

Thoughts ?
