glutMenuStatusFunc -- Modern variant of glutMenuStateFunc()
OpenGLUT - menucallback
glutMenuStatusFunc(void( *callback )( int status, int x, int y ));
callback Client menu status hook.
Broadly, OpenGLUT operates in two modes. At any given time, it is either in menu mode (with a popup menu display, possibly with subitems) or
it is not.
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 transi-
tion took place.
This callback is bound to both the current window and the current menu .
Your callback is not actually called presently.

glutSetWindow -- Select the <i>current window</i>
OpenGLUT - window
ID Window identifier
Sets the current window to ID.
All OpenGL rendering goes to the current window . Many OpenGLUT functions also implicitly use the current window .
Many OpenGLUT callback operations are tied to a window. When your callback is invoked, OpenGLUT will set that particular window to be the
current window . However, some callbacks---such as that registered via glutIdleFunc()---do not have associated windows. If a callback is
not associated to a particular window, then when OpenGLUT invokes that callback you should always use glutSetWindow() to select the appro-
priate window before doing any OpenGL rendering or doing any OpenGLUT window-related operations.
There may be cases when you can get away with assuming that the current window is unchanged since some prior time, but OpenGLUT has con-
siderable liberaty with respect to when it invokes your functions. Also, your program may add more windows or more operations on other win-
dows as you develop it.
Lastly, this is a convenient way to select among multiple windows for drawing without actually waiting for that window's display callback.
Simply set the current window and draw immediately. This is not always advisable, but may be practical.
It is an error to set the current window to a non-existant window (e.g., one that you have closed). A warning will be printed on stderr
if you try to do so, and the current window should be unchanged.
