Well I guess we can enable it on ES also then. But the bigger question 
is whether there is a requirement from an extension to enable it on GLX, 
see patch 1.

Anyone know if the Nvidia or AMD blobs enable this? I was told Feral 
games might be using this but I'm becoming unsure about that. Either way 
it could still be useful to enable it via a config option for some games.
