/**
 * Native bindings to the OES_vertex_array_object extension.
 * 
 * This extension introduces vertex array objects which encapsulate vertex array states on the server side (vertex buffer objects). These objects aim to
 * keep pointers to vertex data and to provide names for different sets of vertex data. Therefore applications are allowed to rapidly switch between
 * different sets of vertex array state, and to easily return to the default vertex array state.
