  27  *
  28  * Simple test of APPLE_vertex_array_object functionality.  This test creates
  29  * a VAO, pushed it (via \c glPushClientAttrib), modifies the VAO, then pops
  30  * it (via \c glPopClientAttrib).  After popping, the state of the VAO is
  31  * examined.
  32  *
  33  * According to the APPLE_vertex_array_object spec, the contents of the VAO
  34  * should be restored to the values that they had when pushed.
