From GD::Graph

Hmm, it's not in the POD anywhere... but I see you looked in the code. No fair. :-)

This is disabled, though. Does that mean it doesn't work, or they just haven't tried it? If it works, I can't quite seem to figure out how. Reading the GD POD, it says setAntiAliased is used to set the color for anti-aliased lines, but it doesn't say how to enable antialiasing. And even if it did, that would require digging into GD::Graph's internals from outside, which seems ugly. Any other ideas?
