created stub for printing with OpenGL toolkit
Printing with graphics_toolkit FLTK has some known limitations:

* Tex/Latex symbols won't show up in the generated print even if they are
visible in the plot window. See bugs #42988, [| #42320], #42340 which are
mostly duplicate entries for the same problem.

* Can't print multiline text objects: [ bug#31468]

But you can use LaTex if you want to include symbols or formulas.
See "help print" for a description of 'pslatex', 'epslatex'
'pdflatex', 'pslatexstandalone', 'epslatexstandalone', 'pdflatexstandalone'
