glutremovelayer(3)
NAME
glutRemoveOverlay - removes the overlay (if one exists)
from the current window.
SYNTAX
void glutRemoveOverlay(void);
DESCRIPTION
glutRemoveOverlay removes the overlay (if one exists). It
is safe to call glutRemoveOverlay even if no overlay is
currently established--it does nothing in this case.
Implicitly, the window's layer in use changes to the nor
mal plane immediately once the overlay is removed.
If the program intends to re-establish the overlay later,
it is typically faster and less resource intensive to use
glutHideOverlay and glutShowOverlay to simply change the
display status of the overlay.
