The available_graphics_toolkits() reports those backend that have been 
initialized.

If you first type "graphics_toolkit fltk" and then type 
"available_graphics_toolkits" you'll see fltk listed.

octave:1> available_graphics_toolkits 
ans = 
{
  [1,1] = gnuplot
}
octave:2> graphics_toolkit fltk
octave:3> available_graphics_toolkits 
ans = 
{
  [1,1] = fltk
  [1,2] = gnuplot
}
