All,
The code in gl-render.cc was incorrectly turning off line anti-aliasing all
of the time. This changeset restores the correct behavior
(http://hg.savannah.gnu.org/hgweb/octave/rev/be8d7721ac16). Octave now
looks to use Full Scene Anti-Aliasing (GL_MULTISAMPLE) first. If this is
not available then it tries to use the old built-in algorithm
(GL_LINE_SMOOTH). I would welcome some comments about the desirablility of
this feature. My screen does not support GL_MULTISAMPLE and I find that I
prefer jagged edges to the attempt by OpenGL to anti-alias the lines. If
enough OpenGL implementations are bad it may be better to have jagged lines
if GL_MULTISAMPLE is not available.

Rik, for reference, this is what I get on Mac OS X.
