'''OpenGL extension EXT.vertex_array

This module customises the behaviour of the 
OpenGL.raw.GL.EXT.vertex_array to provide a more 
Python-friendly API

Overview (from thespec import 
  
  This extension adds the ability to specify multiple geometric primitives
  with very few subroutine calls.  Instead of calling an OpenGL procedure
  to pass each individual vertex, normal, or color, separate arrays
  of vertexes, normals, and colors are prespecified, and are used to
  define a sequence of primitives (all of the same type) when a single
  call is made to DrawArraysEXT.  A stride mechanism is provided so that
  an application can choose to keep all vertex data staggered in a
  single array, or sparsely in separate arrays.  Single-array storage
  may optimize performance on some implementations.
  
  This extension also supports the rendering of individual array elements,
  each specified as an index into the enabled arrays.

The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/vertex_array.txt
