Hi, [EMAIL PROTECTED] (2005-03-01 at 2059.06 -0800): It ought to be easy enough to detect when antialiasing will be needed and automagically turn it on. I havnt looked at the supersampling code yet, but I think it might be much faster to do the supersampling in a second pass since such a

Hi, [EMAIL PROTECTED] (2005-03-01 at 2248.36 +0100): Supersampling is to avoid aliasing, which is not caused only by those discontinuities but high frequency data (IIRC abrupt change is like infinite frequency). You can have aliasing with a square wave (segments that do not match) but also
