This patch adds a new Cycles device with similar functionality to the
existing GPU devices. Kernel compilation and runtime interaction happen
via oneAPI DPC++ compiler and SYCL API.
This implementation is primarly focusing on Intel® Arc™ GPUs and other
future Intel GPUs. The first supported drivers are 101.1660 on Windows
and 22.10.22597 on Linux.
The necessary tools for compilation are:
- A SYCL compiler such as oneAPI DPC++ compiler or
https://github.com/intel/llvm
- Intel® oneAPI Level Zero which is used for low level device queries:
https://github.com/oneapi-src/level-zero
- To optionally generate prebuilt graphics binaries: Intel® Graphics
Compiler All are included in Linux precompiled libraries on svn:
https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for
Windows precompiled binaries but for the graphics compiler, available
as "Intel® Graphics Offline Compiler for OpenCL™ Code" from
https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html,
for which path can be set as OCLOC_INSTALL_DIR.
Being based on the open SYCL standard, this implementation could also be
extended to run on other compatible non-Intel hardware in the future.

Patch implements better way to control playback speed than it is
possible to do with speed effect. Speed factor property can be set in
Time panel.
There are 2 layers of control:
Option to retime movie to match scene FPS rate.
Custom speed factor to control playback rate.
Since playback rate is strip property, it is now possible to manipulate
strip as normal one even if it is retimed.
To facilitate manipulation, some functions need to consider speed factor
and apply necessary corrections to strip offset or strip start. These
corrections may need to be float numbers, so start and offsets must be
float as well.
Sound strips now use speed factor instead of pitch. This means, that
strips will change length to match usable length. In addition, it is
possible to group movie and sound strip and change speed of meta strip.
This commit adds the ability to test Eevee viewport playback performance tests.
Tests should be placed in `lib/benchmarks/eevee/*/*.blend`. {rBL62962} added
initial test files. See https://wiki.blender.org/wiki/Tools/Tests/Performance how
to set it up.
To record the playback performance the test start the viewport playback, and adds
a post frame change handler.
This handler will go over the next steps:
* Ensures the viewport is set to rendered mode.
* Wait for shaders to be compiled. Utilizes `bpy.app.is_job_running` function when
available (v3.3) to wait for shader compilation to finish. When not available will wait
for one minute.
* Draw several warmup frames
* Record for 10 seconds tracking the number of frames drawn and performance counters.
* When ready print the result to the console. The results will be extracted when the
benchmark has run.

terminateMantaflow was never called, this leak is more of a technicality
since it's only called on exit.
Also make Py_Initialize/Py_Finalize optional in Pd:setup/finalize
as it caused Blender to crash, finalizing Python twice.
Add a patch to extern/mantaflow to keep track of changes in Blender
from up-stream.
Tagging the object for copy on write in order to change the mode on the
evaluated object was already done when entering sculpt mode, it should
happen when exiting sculpt mode as well.
Also use the message system to tag updates of the mode property.
This is commonly done for other "mode switch" operators. It's
best to be consistent here, though I don't know that lacking that
caused any issues.
Oversight in rB7724251af81f. Skip saving selection properties
for UV edge ring operator as it allows the operator to re-use
the value that was previously set using the key-map.

This could result in wrong skipping of SVM nodes in the graph. Now make the
logic consistent with the clamping in the OSL implementation and constant
folding.
Thanks to Christophe Hery for finding the problem and providing the fix.
This was preventing correct attribute rendering with multiple attributes.
Since the `CurveInfos` struct is used for data sharing between C++ and
GLSL and inside a UBO it needs to obey the `std140` alignment rules which
states that arrays of scalars are padded to the size of `vec4` for each
array entry.

GLEW does not support GLX and EGL at the same time, and the distribution version
is likely to have GLX.
This also refactors the code so all OpenGL related CMake options are together.

Optionally use `sphinx_changelog_gen.py` to dump current version of the
API in a JSON file, and use closest previous one listed in given index
file to create a changelog RST page for Sphinx.
Part of {T97663}.
Main change is to make it use JSON format for its dump files, instead of
some Python code.
It also introduces an index for those API dump files, mapping a blender
version to the relevant file path.
This is then used to automatically the most recent (version-number wise)
previous API dump to compare against current one, when generating the
change log RST file.
Part of {T97663}.
This was a mistake in 17a773cdce - I did not notice existing set
function and assumed, that property set DNA directly.
Both get and set functions are now available and readonly flag is
removed.
Latest OpenSubdiv builds without GLEW by default, which is also what we do
for precompiled libraries. So there is no need for compatibility checking
with system GLEW.
Additionally WITH_SYSTEM_GLEW is turned off by default for Blender, and this
logic was presumably added when it was still on by default a few years ago.
Also remove outdated mention of glew-mx, we use intern/glew-mx and no
external library for this.

* TBB MEX version is now 2021, since this versin introduces 'oneTBB'

The mask is expected to be always be displayed smooth, and the
option mainly existed for some legacy drivers. IF smooth drawing
causes issues it should be fixed in the drawing code, not as an
option in the interface.

The camera frame (used for selection) was drawn outside the near
clipping plane in those cases.
This has been an issue before as seen in the following commits:
- rB6e7e6832e87
- rB33d322873e6
- rB4f9451c0442
Remaining issue was that the code which ensure the frame isn't behind
the near clipping plane was not taking into account the camera could be
scaled (in Z).
A caller of `BKE_camera_view_frame_ex` (namely
`OVERLAY_camera_cache_populate`) applies scale (also on the depth) which
does not play well with the way `BKE_camera_view_frame_ex` did it.
Now take Z scale into account.

Selection of Python Console renders in front of the text.
Since the default theme uses a low opacity selection color,
it isn't obvious, but increasing alpha to 100% shows it clearly.

Instead, create keyboard two states when the keyboard layout is set
(one with & one without num-lock pressed).
This avoids key-press lookups having to check if num-lock exists and
setting the keyboard state for key press & release events.
No functional changes.
Accessing the symbols for keys with no modifiers & num-lock enabled
has unintended consequences for some keyboard layouts that use this
to switch layers.
Resolve by restricting num-locked lookups to keys typically toggled
with num-lock (key-pad home, page up/down ... etc).
Implement scan-code fallback when the scan-code used for AccentGrave
on US keyboards doesn't map to a key known to GHOST.
Without this, shortcuts that use AccentGrave are inaccessible and the
key does nothing.
This matches functionality from X11, see [0].
