-TODO: an overview for wxPen.
+wxPen uses a reference counting system, so assignments between brushes are very
+cheap. You can therefore use actual wxPen objects instead of pointers without
+efficiency problems. Once one wxPen object changes its data it will create its
+own pen data internally so that other pens, which previously shared the
+data using the reference counting, are not affected.
