      * Feature in Windows.  The SysLink window class
      * does not include CS_DBLCLKS.  This means that these
      * controls will not get double click messages such as
      * WM_LBUTTONDBLCLK.  The fix is to register a new
      * window class with CS_DBLCLKS.
      *
      * NOTE:  Screen readers look for the exact class name
      * of the control in order to provide the correct kind
      * of assistance.  Therefore, it is critical that the
      * new window class have the same name.  It is possible
      * to register a local window class with the same name
      * as a global class.  Since bits that affect the class
      * are being changed, it is possible that other native
      * code, other than SWT, could create a control with
      * this class name, and fail unexpectedly.
