+ * has been created. Therefore we decided on the following
+ * behaviour, both under Windows and under UNIX/X11:
+ * - When you create a window with position (x,y) and size
+ * (w,h), the upper left hand corner of the outside of the
+ * window is at (x,y) and the size of the drawable area is
+ * (w,h).
+ * - When you query the size and position of the window--as
+ * is happening here for Windows--"freeglut" will return
+ * the size of the drawable area--the (w,h) that you
+ * specified when you created the window--and the coordinates
+ * of the upper left hand corner of the drawable area, i.e.
+ * of the client rect--which is NOT the (x,y) you specified.
