NAME
     glutPopWindow -- Request to raise the current window to the top

LIBRARY
     OpenGLUT - window

SYNOPSIS
     #include <openglut.h>

     void
     glutPopWindow(void);

DESCRIPTION
     Request that the  current window	be brought to the top.

     A window can be in front of or behind other windows, as determined by the z-order from front to back.  Top-level OpenGLUT windows can be
     placed at the front or back of the z-order by means of the glutPopWindow() and glutPushWindow() API functions.

     A z-order also applies to the subwindows of a top-level window.  While the z-order of top-level windows can usually be adjusted by the user,
     subwindow z-order is controlled entirely by the application.

     If this has any effect on your window's visibility, you should receive a glutWindowStatusFunc() callback and a glutDisplayFunc() callback.

CAVEATS
     The z-order of top-level windows is ultimately managed by the windowing system.  Therefore, a push or pop request by an OpenGLUT application
     may not necessarily succeed or take immediate effect.

     Not applicable to offscreen windows.
