+ *
+ * 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.
