/**
 * \name dispatch_sanity.cpp
 *
 * Verify that only set of functions that should be available in a particular
 * API are available in that API.
 *
 * The list of expected functions originally came from the functions set by
 * api_exec_es2.c.  This file no longer exists in Mesa (but api_exec_es1.c was
 * still generated at the time this test was written).  It was the generated
 * file that configured the dispatch table for ES2 contexts.  This test
 * verifies that all of the functions set by the old api_exec_es2.c (with the
 * recent addition of VAO functions) are set in the dispatch table and
 * everything else is a NOP.
 *
 * When adding extensions that add new functions, this test will need to be
 * modified to expect dispatch functions for the new extension functions.
