This seems to work very nicely! Wonderful :-)

I just played a bit around with the FLTK backend and have a few
observations:

*) If I do

imshow (rand (100))
text (30, 30, "Hello, world")

and print the result then the text is visible in the print, but
not on screen. I don't know if this is a bug in the on-screen
visualisation or in the printing, though.

*) If I do

sphere ()
print sphere.pdf

then I get the attached file. In this, the sphere seems
'semi-transparent'. By that I mean that I can see the edges of
the occluded part of the sphere in the print. I cannot see these
on the screen

Regarding the text over the image, I see the text on my screen. It is much easier to see if I ...

    text (30, 30, "Hello, World", "color", "b", "fontsize", 30)

Regarding the "occluded" part (new word for me!), if I understand you correctly this is a feature of how the surface plot is drawn. Each rectangle is actually drawn as a pair of triangles. The edges of the triangles, along the rectangle's diagonal, are visible. I see the same effect when I produce pdf output from Matlab (plot is attached). Perhaps this is a feature of OpenGL?
