numeric
The state of anti-aliasing for graphic_window. Anti-aliasing is a facility which masks the jagged edges produced when vectors or text characters are displayed at angles which are not parallel to major axes. The masking is done by a dithering process resulting in smoother-looking vectors.
By default a graphic window has anti-aliasing turned off (0), but setting this attribute to 1 will turn the feature on. Note: anti-aliased graphics currently take approximately 50% longer to draw.
This facility is not available on Unix implementations.
