GeometryOffsetPolyline2d Method

Inflates or deflates polyline by delta units (pixels), producing polygons. If delta is positive, makes the polyline grow outward. Returns an array of polygons because inflating/deflating may result in multiple discrete polygons. If delta is negative, returns an empty array.

Each polygon's vertices will be rounded as determined by join_type, see GeometryPolyJoinType.

Each polygon's endpoints will be rounded as determined by end_type, see GeometryPolyEndType.

The operation may result in an outer polygon (boundary) and inner polygon (hole) produced which could be distinguished by calling IsPolygonClockwise(Vector2).
