Hi Michael, I think the current setting for anti-aliasing works fine for me. Please note that I have the line width set to "0.1", which is really and arbitrary number less than 1, but it seems to reduce the original heaviness of the lines.
(The line width is set in the current .ini)

I notice that the "smoothness" of MoI's anti-aliased lines fall somewhere in-between the quality of CorelDRAW's (which is course) and Adobe Illustrator's (which is often too blurry). MoI's drawing had one great advantage I really like, and that is the literal and correct triangle shapes at the corners of curves and lines that come to an exact point. Now that's a sharp look.
