Function arcXY

arcXY(
    centre: Point,
    radius: number,
    start_angle: number,
    arc_angle: number,
    segments?: number,
): Point[]
Generates a 2D arc from a center point, covering a specific angular sweep.
Parameters
- centre: Point
  The geometric center of the arc curve.
- radius: number
  Spatial radius of the arc.
- start_angle: number
  The starting polar angle in radians.
- arc_angle: number
  The total sweep angle in radians (positive = CCW).
- segments: number = 100
  Interpolation segments (default 100).
Returns Point[]
Array of Points traversing the arc continuously.
