+Summary: System.Drawing.DrawCurve with numberOfSegments problem
+
+Description of Problem:
+
+public void DrawCurve(
+   Pen pen,
+   Point[] points,
+   int offset,
+   int numberOfSegments,
+   float tension
+);
+
+doesn't draw a proper curve, when you use an array and pass a specified
+number of elements of the array as numberOfSegments. Haven't checked the
+other overloaded methods which use numberOfSegments.
+
+Steps to reproduce the problem:
+Check the test case.
+
+How often does this happen?
+Always
