    Not bad. It feels like by the time we get tesselation shaders, everything in 4.1 and 4.2 will have been done. If that's the case, how about going from Mesa 10 directly to Mesa 13?

    How about, going from Mesa 10 to Mesa 11, and matching directx numbering. ( OpenGL 4.x = DirectX 11 )

    So what real world problem does the extension solve?

    Rendering all faces of a cube shadow map (or any cube map render target really) with one render pass.

    Incorrect. What you're talking about is layered rendering, which is part of GL 3.2.

    How about moving to roman numerals?

    Therefore stay forever at version 11?

    Yeah, 4.1 and 4.2 changes will almost certainly be done before 4.0 is, just like 3.3 was done before 3.2.

    In addition to tesselation shaders, 4.0 also requires some pretty big changes in Mesa for fp64 and glsl subroutines. I haven't seen any sign that anyone is working on those either.
