All plots in [1] were made with Octave 4.1.0+ aka default branch. There
are some plot regressions (like the missing colorbars) which are also
not printed when using the default FLTK backend. Perhaps I should create
a new comarison with OSMesa, FLTK, gnuplot side by side.

__gl_print__ is compiled with mkoctfile so I think the easiest way to
link against a specific Octave version is to explicitly use
mkoctfile-4.1.0+ or mkoctfile-3.8.2.
