<description>
Draws a unfilled arc between the given angles. The larger the value of [code]point_count[/code], the smoother the curve. See also [method draw_circle].
[b]Note:[/b] Line drawing is not accelerated by batching if [code]antialiased[/code] is [code]true[/code].
[b]Note:[/b] Due to how it works, built-in antialiasing will not look correct for translucent lines and may not work on certain platforms. As a workaround, install the [url=https://github.com/godot-extended-libraries/godot-antialiased-line2d]Antialiased Line2D[/url] add-on then create an AntialiasedRegularPolygon2D node. That node relies on a texture with custom mipmaps to perform antialiasing. 2D batching is also still supported with those antialiased lines.

A line through several points in 2D space.
A line through several points in 2D space. Supports varying width and color over the line's length, texturing, and several cap/joint types.
[b]Note:[/b] By default, Godot can only draw up to 4,096 polygon points at a time.
