/**

* Simple test of APPLE_vertex_array_object functionality. This test creates
* a VAO, pushed it (via \c glPushClientAttrib), modifies the VAO, then pops
* it (via \c glPopClientAttrib). After popping, the state of the VAO is
* examined.
*
* According to the APPLE_vertex_array_object spec, the contents of the VAO
* should be restored to the values that they had when pushed.
