Italo Nicola d7b9da2673 mesa/main: allow readpix/teximage to read from implicitly multisampled fbos
The GL_EXT_multisampled_render_to_texture spec explicitly allow reading
from these FBOs.

"Similarly, for ReadPixels:
 'An INVALID_OPERATION error is generated if the value of READ_-
FRAMEBUFFER_BINDING (see section 9) is non-zero, the read framebuffer is
framebuffer complete, and the value of SAMPLE_BUFFERS for the read
framebuffer is one.'

 These errors do not apply to textures and renderbuffers that have
associated multisample data specified by the mechanisms described in
this extension, i.e., the above operations are allowed even when
SAMPLE_BUFFERS is non-zero for renderbuffers created via Renderbuffer-
StorageMultisampleEXT or textures attached via FramebufferTexture2D-
MultisampleEXT."

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
