glutShowOverlay, glutHideOverlay - shows or hides the overlay of the current
window
void glutShowOverlay(void);
void glutHideOverlay(void);
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.
