I checked in the following changesets:

  http://hg.savannah.gnu.org/hgweb/octave/rev/8ac9687dbe9f
  http://hg.savannah.gnu.org/hgweb/octave/rev/b124b83e5626

They replace the term "backend" with "graphics toolkit", and rename
the "backend" function to "graphics_toolkit".  Now you will need to
use

  graphics_toolkit ("fltk")

to initialize and switch to the fltk graphics toolkit.

If there is any objection to this change, please speak up soon.
