73fe848e07 Fix: Cycles log levels conflict with macros on some platforms
In particular DEBUG, but prefix all of them to be sure.

d32d787f5f Clang-Format: Allow empty functions to be single-line
For example

```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```

becomes

```
OIIOOutputDriver::~OIIOOutputDriver() {}
```

Saves quite some vertical space, which is especially handy for
constructors.

3d9f4012dc Cycles: Fixes for viewport render on Metal drawing backend
This change fixes issues with viewport rendering when Metal
GPU backend is used for drawing. This is not a default build
configuration and requires the following tweaks:

- Enable WITH_METAL_BACKEND CMake option (set it to on)
- Use `--gpu-backend metal` command line arguments

It also helps using the `--factory-startup` command line
argument to ensure Eevee is not used (it is not ported and
will crash).

The root of the problem was in the use of glViewport().
It is replaced with the GPU_viewport_size_get_i() which
is supposed to be portable equivalent form the GPU module.
Without this change the viewport size is detected to be 0
which backfired in few places.

The rest of the changes were to make the code more robust
in the extreme conditions instead of asserting or crashing.

Simplified and streamlined GPU resources creation in the
display driver. It was a bit convoluted mix of creation of
the GPU resources and resizing them to the proper size. It
even seemed to be done in the reverse order. Now it is as
simple as "just ensure GPU resources are there for the
given texture or buffer size".

Also avoid division by zero in the tile manager.

9cfc7967dd Cycles: use SPDX license headers
* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
  to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.

292c2cefe3 Fix T93727: Tiled render error in Cycles after changing temp directory
Consider temporary directory to be variant part of session configuration
which gets communicated to the tile manager on render reset.

This allows to be able to render with one temp directory, change the
directory, render again and have proper render result even with enabled
persistent data.

For the ease of access to the temp directory expose it via the render
engine API (engine.temp_directory).

ae28d90578 Fix T93350: Cycles renders shows black during rendering huge resolutions
The root of the issue is caused by Cycles ignoring OpenGL limitation on
the maximum resolution of textures: Cycles was allocating texture of the
final render resolution. It was exceeding limitation on certain GPUs and
driver.

The idea is simple: use multiple textures for the display, each of which
will fit into OpenGL limitations.

There is some code which allows the display driver to know when to start
the new tile. Also added some code to allow force graphics interop to be
re-created. The latter one ended up not used in the final version of the
patch, but it might be helpful for other drivers implementation.

The tile size is limited to 8K now as it is the safest size for textures
on many GPUs and OpenGL drivers.

This is an updated fix with a workaround for freezing with the NVIDIA
driver on Linux.

204ae33d75 Revert "Fix T93350: Cycles renders shows black during rendering huge resolutions"
This reverts commit 5e37f70307.

It is leading to freezing of the entire desktop for a few seconds when stopping
3D viewport rendering on my Linux / NVIDIA system.

de8a46c6ad Fix T93008: Cycles: Huge memory spike when saving tile to disk
The root of the problem lies in bug in OIIO which we can work around
from our side (which does not affect pack memory usage).

Thanks Brecht for finding the root cause!

fd25e883e2 Cycles: remove prefix from source code file names
Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.

d7d40745fa Cycles: changes to source code folders structure
* Split render/ into scene/ and session/. The scene/ folder now contains the
  scene and its nodes. The session/ folder contains the render session and
  associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
  kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
