 This callback is not bound to any window. This callback is bound to a specific menu.

| Modern variant of glutMenuStateFunc(). 
 
 When moving from non-menu to menu status, callback (if defined) will be called with GLUT_MENU_IN_USE . Conversely, when moving from menu to non-menu status, callback (if defined) will be called with GLUT_MENU_NOT_IN_USE . This differs from glutMenuStateFunc() in that callback is also given the x and y coordinates of the mouse when the menu state transition took place. This callback is bound to both the current window and the current menu.
