110     The built-in variable gl_FragFullyCoveredNV is a fragment-shader input 
112     enabled and the fragment is fully covered by the generating primitive, and 
123     fragment programs can read the "fragment.fullycovered" attribute to 
124     determine if the fragment is fully covered by the primitive.

139     If a fragment attribute binding matches "fragment.fullycovered", the "x"
140     component of the fragment attribute variable is set to either 0 or 1,
141     depending on how the fragment is covered by the primitive.  If 
142     CONSERVATIVE_RASTERIZATION is enabled and the fragment is completely 
148     specified, "fragment.fullycovered" binding is unavailable.
