  afx_msg UINT OnNcHitTest( CPoint  point  );
 
  Parameter   Description
 
  <point>     Contains the x- and y-coordinates of the cursor. These
              coordinates are always screen coordinates.
 
  Remarks
 
  Called for the CWnd that contains the cursor (or the CWnd that used the
  SetCapture member function to capture the mouse input) every time the
  mouse is moved.
 
  This message-handler member function calls the Default member
  function. Override this member function in your derived class to handle
  the WM_NCHITTEST message.
