Timothy Arceri 10556f735c glsl: relax rule on varying matching for shaders older than 4.20 This expands on commit `c54c42321e`. See the code comment for full justifications. At the time of the previous commit Ian wanted to limit the relaxing of the rule to GLSL 3.30 as that was the highest version of shaders seen in the wild that were having trouble with the stricter rules. However since then I've found that the long standing issue with tess shaders failing to compile in the game 'Layers Of Fear' is due to this same issue. The game uses 4.10 shaders and also makes use of explicit varying locations, so here we relax the rule to 4.20 and make sure to apply the restriction to shaders using varyings with explicit locations also.

Build & install
---------------

You can find more information in our documentation (`docs/install.rst

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
