Danylo Piliaiev 847ad80e03 tu/lrz: Consider FS depth layout when gl_FragDepth is written
Specifying depth write direction in shader may help us. E.g.
If depth test is GREATER and FS specifies FRAG_DEPTH_LAYOUT_LESS
it means that LRZ won't kill any fragment that shouldn't be killed,
in other words, FS can only reduce the depth value which could
make fragment to NOT pass with GREATER depth test. We just have to
enable late Z test.

There is the same concept in D3D11 and it is seen e.g. in "Stray" game.

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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install

Support
-------

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.
