'''OpenGL extension NV.light_max_exponent
Overview (from the spec)
Default OpenGL does not permit a shininess or spot exponent over
128.0. This extension permits implementations to support and
advertise a maximum shininess and spot exponent beyond 128.0.
Note that extremely high exponents for shininess and/or spot light
cutoff will require sufficiently high tessellation for acceptable
lighting results.
Paul Deifenbach's thesis suggests that higher exponents are
necessary to approximate BRDFs with per-vertex ligthing and
multiple passes.
The official definition of this extension is available here:
