'''OpenGL extension NV.vertex_array_range2
Overview (from the spec)
Enabling and disabling the vertex array range is specified by the
original NV_vertex_array_range extension specification to flush the
vertex array range implicitly. In retrospect, this semantic is
extremely misconceived and creates terrible performance problems
for any application that wishes to mix conventional vertex arrays
with vertex arrange range-enabled vertex arrays.
This extension provides a new token for enabling/disabling the
vertex array range that does NOT perform an implicit vertex array
range flush when the enable/disable is performed.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/NV/vertex_array_range2.txt
