   * @param index
   *            Specifies the index of the generic vertex attribute to be
   *            modified.
   * @param size
   *            Specifies the number of components per generic vertex
   *            attribute. Must be 1, 2, 3, or 4. The initial value is 4.
   * @param type
   *            Specifies the data type of each component in the array.
   *            Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT,
   *            GL_UNSIGNED_SHORT, GL_FIXED, or GL_FLOAT are accepted. The
   *            initial value is GL_FLOAT.
   * @param normalized
   *            Specifies whether fixed-point data values should be normalized
   *            (true) or converted directly as fixed-point values
   *            (false) when they are accessed.
   * @param stride
   *            The byte offset between consecutive generic vertex
   *            attributes. If stride is 0, the generic vertex attributes are
   *            understood to be tightly packed in the array. The initial
   *            value is 0.
   * @param offset The byte offset into the buffer object's data store
