  Message : Move VAO buffer clearing code to the destructor, instead of the constructor. This fixes assertion failures during the VertexArray destructor in Debug mode. TRAC #23390 Signed-off-by: Shannon Woods Signed-off-by: Geoff Lang Authored-by: Jamie Madill

  // This class contains prototypes for representing GLES 3 Vertex Array Objects:
  //
  //   The buffer objects that are to be used by the vertex stage of the GL are collected
  //   together to form a vertex array object. All state related to the definition of data used
  //   by the vertex processor is encapsulated in a vertex array object.
