From 08be1d288f216232d3974f5997b266a8dd720928 Mon Sep 17 00:00:00 2001
From: Ian Romanick <ian.d.romanick@intel.com>
Date: Fri, 27 Jul 2012 11:56:42 -0700
Subject: [PATCH] mesa/es: Validate glEnable cap in Mesa code rather than the
 ES wrapper

Also handle glDisable, glIsEnabled, glEnableClientState, and
glDisableClientState.

v2: Add proper core-profile and GLES3 filtering.
