NAME
     glutPushWindow -- Request to lower the current window to the bottom.

LIBRARY
     OpenGLUT - window

SYNOPSIS
     #include <openglut.h>

     void
     glutPushWindow(void);

DESCRIPTION
     This function requests that the  current window   be ``pushed'' to the back.

     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.

     There may not be an immediate effect to this function.  Wait for the glutWindowStatusFunc() callback to tell you about whatever obscured/vis-
     ible status your window achieves.

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.
