The AntiAlias flag, when true, advises the renderer to apply anti-aliasing when painting the shading. The default is false. Anti-aliasing can improve the visual smoothness of shading edges and gradient transitions, especially at screen resolution.

The renderer may ignore this flag if it does not support anti-aliasing for shadings, or if the output device does not benefit from it.
