Juan A. Suarez Romero 3b81d2d30d mesa/st: do not expose ARB_shader_image_load_store if not fully implemented
So far we were checking ARB_shader_image_load_store is supported as
requirement to expose GLES 3.1.

But when this extension functionality was added in GLES 3.1 spec, it
was relaxed, and one of its requirements, the support for formatless
writing, was not included.

So this means that a driver that support all the extension
functionality except formatless writing, could expose GLES 3.1, but it
couldn't expose the extension itself (nor GL 4.2, which requires fully
implementation of the extension).

v2:
 - Add the same exposure treatment to ARB_shader_image_size (Ilia).

v3:
 - Remove dependency for OES_texture_buffer (Ilia).
 - Check image resources for GLES 3.1 (Ilia).

v4:
 - Check for MaxImageUniforms in compute shader (Ilia).
 - Check for max combined image uniforms/ssbo (Ilia).

v5:
 - Remove ARB_shader_image_load_store from check (Ilia).
 - ARB_shader_image_store and ARB_shader_image required for
   ARB_ES3_1_compatibility (Ilia).

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


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

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. 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 `OFTC's #dri-devel
<irc://irc.oftc.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.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
