//   This function shows  fireworks4 pop-up menu with relative positon 
//   from image object ,  not with absolute position.
//
//   argv[0]  : fireworks pop-up menu object
//   argv[1]  : image name or 'this'  ('this' is anchor object )
//   argv[2]  : relative X position
//   argv[3]  : relative Y position 
//
// HOW TO
// step 1. add next source  in your  HTML.
//
//  <script language="JavaScript1.2" src="NN_fw_menu.js"></script>
//
// step 2. change your onMouseOver evnt handler.
// 
//   before : onMouseOver="window.FW_showMenu( fw_menu0,  absoluteX, absoluteY );"
//   after  : onMouseOver="NN_FW_showMenu( fw_menu0,  'imageName', relativeX, relativeY );" or
//            onMouseOver="NN_FW_showMenu( fw_menu0,  this , relativeX, relativeY );"
