// 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.
