  1. '''OpenGL extension EXT.vertex_array
  2.  
  3. Overview (from the spec)
  4.     
  5.     This extension adds the ability to specify multiple geometric primitives
  6.     with very few subroutine calls.  Instead of calling an OpenGL procedure
  7.     to pass each individual vertex, normal, or color, separate arrays
  8.     of vertexes, normals, and colors are prespecified, and are used to
  9.     define a sequence of primitives (all of the same type) when a single
  10.     call is made to DrawArraysEXT.  A stride mechanism is provided so that
  11.     an application can choose to keep all vertex data staggered in a
  12.     single array, or sparsely in separate arrays.  Single-array storage
  13.     may optimize performance on some implementations.
  14.     
  15.     This extension also supports the rendering of individual array elements,
  16.     each specified as an index into the enabled arrays.
  17.  
  18. The official definition of this extension is available here:
  19.     http://oss.sgi.com/projects/ogl-sample/registry/EXT/vertex_array.txt
