This extension defines an interface that allows various types of data

This extension introduces named vertex array objects which encapsulate
vertex array state on the client side. The main purpose of these
objects is to keep pointers to static vertex data and provide a name
for different sets of static vertex data.
By extending vertex array range functionality this extension allows multiple
vertex array ranges to exist at one time, including their complete sets of
state, in manner analogous to texture objects.
GenVertexArraysAPPLE creates a list of n number of vertex array object
names. After creating a name, BindVertexArrayAPPLE associates the name with
a vertex array object and selects this vertex array and its associated
state as current. To get back to the default vertex array and its
associated state the client should bind to vertex array named 0.
