glutShowWindow, glutHideWindow, glutIconifyWindow - change
the display status of the current window.

glutHideWindow
	glutHideWindow() -> None
glutIconifyWindow
	glutIconifyWindow() -> None
glutShowWindow
	glutShowWindow() -> None

void glutShowWindow(void);
void glutHideWindow(void);
void glutIconifyWindow(void);

glutShowWindow will show the current window (though it may
still  not be visible if obscured by other shown windows).
glutHideWindow will hide the current window.  glutIconify-
Window will iconify a top-level window, but GLUT prohibits
iconification of a subwindow.  The effect of showing, hid-
ing,  and  iconifying  windows does not take place immedi-
ately. Instead the requests are saved for  execution  upon
return  to  the GLUT event loop. Subsequent show, hide, or
iconification requests on a window replace the  previously
saved request for that window. The effect of hiding, show-
ing, or iconifying top-level windows  is  subject  to  the
window system's policy for displaying windows.

glutPopWindow, glutPushWindow
