-				Adds a point to a curve at [param position] relative to the [Curve2D]'s position, with control points [param in] and [param out].
-				If [param at_position] is given, the point is inserted before the point number [param at_position], moving that point (and every point after) after the inserted point. If [param at_position] is not given, or is an illegal value ([code]at_position &lt;0[/code] or [code]at_position &gt;= [method get_point_count][/code]), the point will be appended at the end of the point list.
+				Adds a point with the specified [param position] relative to the curve's own position, with control points [param in] and [param out]. Appends the new point at the end of the point list.
+				If [param index] is given, the new point is inserted before the existing point identified by index [param index]. Every existing point starting from [param index] is shifted further down the list of points. The index must be greater than or equal to [code]0[/code] and must not exceed the number of existing points in the line. See [member point_count].
