glutWindowStatusFunc -- Sets the window status callback.
OpenGLUT - windowcallback
glutWindowStatusFunc(void( *callback )( int state ));
callback Client window status hook.
When the visibility status of your window changes, OpenGLUT either invokes the callback registered by this function or the Visibility
callback---or neither, if you have not registered either callback.
This differs from glutVisbilityFunc() in that the callback has three states, rather than two, that it may receive. These states are:
- GLUT_VISIBLE (every pixel visible)
- GLUT_FULLY_COVERED (every pixel obscured)
- GLUT_HIDDEN (intermediate)
The callback is bound to the current window .
Makes glutVisibilityFunc() obsolete.

glutVisibilityFunc - sets the visibility callback for the current window.
void glutVisibilityFunc(void (*func)(int state));
func The new visibility callback function.
glutVisibilityFunc sets the visibility callback for the current window. The visibility callback for a window is called when the visibility
of a window changes. The state callback parameter is either GLUT_NOT_VISIBLE or GLUT_VISIBLE depending on the current visibility of the
window. GLUT_VISIBLE does not distinguish a window being totally versus partially visible. GLUT_NOT_VISIBLE means no part of the window is
visible, i.e., until the window's visibility changes, all further rendering to the window is discarded.
GLUT considers a window visible if any pixel of the window is visible or any pixel of any descendant window is visible on the screen.
Passing NULL to glutVisibilityFunc disables the generation of the visibility callback.
If the visibility callback for a window is disabled and later re-enabled, the visibility status of the window is undefined; any change in
window visibility will be reported, that is if you disable a visibility callback and re-enable the callback, you are guaranteed the next
visibility change will be reported.
