Octave 3.1.50 available for ftp

[John W. Eaton]

A new snapshot of Octave is now available for ftp from ftp.octave.org in the
directory /pub/octave/bleeding-edge:

  2e7ffb7e79a7d9895136987e14ebebd0  octave-3.1.50.tar.bz2
  52ba9e6f736efbeb279945fc4d9eb069  octave-3.1.50.tar.gz

  -rw-r--r-- 1 506 1012 10699800 Jul 18 21:28 octave-3.1.50.tar.bz2
  -rw-r--r-- 1 506 1012 12264734 Jul 18 21:30 octave-3.1.50.tar.gz

The snapshot is tagged in the usual way (ss-3-1-50) in the Mercurial
archive and will be marked as the "development" version of
Octave on the download page of the Octave web site.

I didn't bother to make diffs from any previous version as they would
be quite large.

This snapshot includes the new experimental OpenGL-based graphics
code, but the gnuplot backend is used by default.  Assuming you have
all the required libraries and have built the OpenGL bits properly,
you should be able to switch to the new backend with the commands

  input_event_hook ("__fltk_redraw__");
  __init_fltk__ ();
  set (0, "defaultfigure__backend__", "fltk");

I'm sure there will be a simpler way to do this once the new backend
code is more mature.
