NAME
       glutShowOverlay, glutHideOverlay - shows or hides the overlay of the current window

SYNTAX
       void glutShowOverlay(void);
       void glutHideOverlay(void);

DESCRIPTION
       glutShowOverlay	shows  the  overlay  of  the current window; glutHideOverlay hides the overlay. The effect of showing or hiding an overlay
       takes place immediately. Note that glutShowOverlay will not actually display the overlay unless the window is also shown (and even a  shown
       window  may  be	obscured by other windows, thereby obscuring the overlay). It is typically faster and less resource intensive to use these
       routines to control the display status of an overlay as opposed to removing and re-establishing the overlay.
