1695 * Name : int WIN32API SetWindowRgn
1696 * Purpose : The SetWindowRgn function sets the window region of a window. The
1697 * window region determines the area within the window where the
1698 * operating system permits drawing. The operating system does not
1699 * display any portion of a window that lies outside of the window region
1700 * When this function is called, the system sends the WM_WINDOWPOSCHANGING and
1701 * WM_WINDOWPOSCHANGED messages to the window.
1702 *
1703 * Parameters: HWND hWnd handle to window whose window region is to be set
1704 * HRGN hRgn handle to region
1705 * BOOL bRedraw window redraw flag
1706 * Variables :
1707 * Result : If the function succeeds, the return value is non-zero.
1708 * If the function fails, the return value is zero.
1709 * Remark :
1710 * Status : UNTESTED STUB
