Details:

I used to insert '\n' in a string to get a items beneath each other with
text() of gtext(). 

gnuplot does this, but the FLTK graphics_toolkit does not use the newlines. 


---- below is what demonstrates the issue (when changing gnuplot to fltk). 


octave:1> graphics_toolkit ('gnuplot') 
octave:2> x=linspace(0,3,100) ; y=sin(x) ;plot(x,y,'r;sin(x);') 
octave:3> s=sprintf('line1\nline2\nline3\n') 
s = line1 
line2 
line3 

octave:4> gtext(s)    %click on the plot somewhere..... 
octave:5> 



I think there should be 1 policy here, independent of the backend.
