Well, i was going to complain, that although it's called "4.0" it does not contain DSA or multi-threaded rendering.

But after more carefully sifting through all the material, i am actually pretty happy with all the progress. And since tessellation does change so many things, i think it is OK to call it "4.0".

Good job guys!

Now that OpenGL has caught up with the most important features of DX11, i really hope 5.0 gets a more thorough API clean-up.
