Adam Jackson 768238fdc0 glx: Fix drawable refcounting for naked Windows 
driFetchDrawable is only ever called from the MakeCurrent path, which
means it has to handle the case of pre-GLX-1.3 Windows being named as
the drawable. When it finds the drawable in the hash, it increments its
refcount before returning it, so for a GLXWindow it would be 2 on first
return, one from glXCreateWindow and one from glXMakeCurrent. But when
it does not find the drawable and creates one for the naked Window, the
reference count on first return would only be 1. As a result, if this
context was then ever bound to a different drawable, the old Window's
DRI drawable state (like the back buffer) would be destroyed.

Fixes piglit's glx-multi-window-single-context and glx-make-current for
a variety of drivers.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


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
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
(`docs/bugs.rst <https://mesa3d.org/bugs.html>`_).


Contributing
------------

Contributions are welcome, and step-by-step instructions can be found in our
