NAME
       glutUseLayer - changes the layer in use for the current window.

SYNTAX
       #include <GLUT/glut.h>

       void glutUseLayer(GLenum layer);

ARGUMENTS
       layer	 Either GLUT_NORMAL or GLUT_OVERLAY, selecting the normal plane or overlay respectively.

DESCRIPTION
       glutUseLayer  changes  the per-window layer in use for the current window, selecting either the normal plane or overlay. The overlay should
       only be specified if an overlay exists, however windows without an overlay may still call glutUseLayer(GLUT_NORMAL).  OpenGL  commands  for
       the window are directed to the current layer in use.

       To query the layer in use for a window, call glutLayerGet(GLUT_LAYER_IN_USE).
