  29  * Tests basic API support for glIsVertexArray().
  30  *
  31  * From the ARB_vertex_array_object spec:
  32  *
  33  *     "The command
  34  *
  35  *         void GenVertexArrays(sizei n, uint *arrays);
  36  *
  37  *      returns <n> previous unused vertex array object names in <arrays>. These
  38  *      names are marked as used, for the purposes of GenVertexArrays only, but
  39  *      they acquire array state only when they are first bound.
  40  *
  41  *      [...]
  42  *
  43  *      A vertex array object is created by binding a name returned by
  44  *      GenVertexArrays with the command
  45  *
  46  *         void BindVertexArray(uint array);"
  47  *
  48  * The APPLE_vertex_array_object spec contains similar wording.
