With this commit, we now use a forked version of MESA which only supports OpenGL 1.1, like the windows implementation does. It exposes : - The same pixel formats - The same set of extensions - Nothing more All of this without taking 10% of your build time. If you need a more modern option, look at the MESA package from Rapps, which is (and must be) maintained outside of this code tree. CORE-7499
