Antialiasing draws a small ring around the edges, which fades to transparency. As a result, edges look much smoother. This is only noticeable when using rounded corners or [member skew].
[b]Note:[/b] When using beveled corners with 45-degree angles ([member corner_detail] = 1), it is recommended to set [member anti_aliasing] to [code]false[/code] to ensure crisp visuals and avoid possible visual glitches.

- This changes the size of the faded ring. Higher values can be used to achieve a "blurry" effect.

+ This changes the size of the antialiasing effect. [code]1.0[/code] is recommended for an optimal result at 100% scale, identical to how rounded rectangles are rendered in web browsers and most vector drawing software.
+ [b]Note:[/b] Higher values may produce a blur effect but can also create undesired artifacts on small boxes with large-radius corners.
