        * XplatUIX11.cs: send a WM_NCPAINT on WM_NCCALCSIZE so that 
        the window gets to paint its borders even if the window is
        getting smaller.
        
        * Form.cs: on a WM_NCPAINT invalidate the entire menu, 
        otherwise the old control buttons would still be painted 
        if the window gets bigger.
        
        * PaintEventArgs.cs: add an internal method so that the clip 
        rectangle can be changed.
