-        vertices : float, (N, 2) array_like
-            The N control points of the next 2-dimensional bezier curve making
-            up self. Note in particular that freestanding points are bezier
-            curves of order 0, and lines are bezier curves of order 1 (with two

+            that freestanding points are bezier curves of order 0, and lines
+            are bezier curves of order 1 (with two control points).
         code : Path.code_type
             The code describing what kind of curve is being returned.
             Path.MOVETO, Path.LINETO, Path.CURVE3, Path.CURVE4 correspond to
             bezier curves with 1, 2, 3, and 4 control points (respectively).
+            Path.CLOSEPOLY is a Path.LINETO with the control points correctly
+            chosen based on the start/end points of the current stroke.
