DESCRIPTION

By default, OpenGLUT operates in "normal" mode, with respect to layers. If you have a layer open and wish to operate on the layer, you must use glutUseLayer().

Bf Sy
 layer Ef
 can take on the following values, indicating the layer mode to use:


 -  Bf Sy
 GLUT_NORMAL Ef
 
 -  Bf Sy
 GLUT_LAYER Ef
 

 

CAVEATS

Unimplemented.

It is unclear what the consequences are if you are in Bf Sy
 GLUT_OVERLAY Ef
