This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

Some GPU's have support for compute shaders, but don't support
GLSL 4.3. This resulted in compiler errors and crashes.
This issue could have been solved by supporting older GLSL languages but
that would have been a hassle to get it right. We already have a
fallback in place for GPU's that don't support compute shaders at all.
This addresses reduced visibility of scenes (as displayed in the VR
headset) that can result from the 8-bit color depth format currently
used for XR swapchain images.
By switching to a swapchain format with higher color depth (RGB10_A2,
RGBA16, RGBA16F) for supported runtimes, visibility in VR should be
noticeably improved.
However, current limitations are lack of support for these higher
color depth formats by some XR runtimes, especially for OpenGL.
Also important to note that GPU_offscreen_create() now explicitly
takes in the texture format (eGPUTextureFormat) instead of a
"high_bitdepth" boolean.

While trying to get Blender 2.93.x LTS to build fine on all release architectures in Debian, I noticed that the misleading use of "mips" as integer variable caused problems when compiling on mips64el. The patch should fix the issue.

ID data-blocks that could be accessed from Python and weren't freed
using BKE_id_free_ex did not release the Python reference count.
Add BKE_libblock_free_data_py function to clear the Python reference
in this case.
Add asserts to ensure no Python reference is held in situations
when ID's are copied for internal use (not exposed through the RNA API),
to ensure these kinds of leaks don't go by unnoticed again.
rBfb87d236edb7 made the values returned by `projmat_dimensions` more
standardized following the documentations. But the functions in Blender
that called `projmat_dimensions` followed a proposal that these values
corresponded to a distance of 1m of clip.
Adjust these functions to follow the new algorithm.
This patch fixes an issue with missing faces when assigning a material slot other than the first to faces on AMD TAHITI cards. Refer to T78390 and T74024 for a description of this issue.
This patch also incorporates fix from T78390 for KAVERI.

The crash happens because `GPU_offscreen_create` is called with `err_out` `NULL`.
This patch proposes a solution within the `GPU_offscreen_create` itself
and raises an error report in the interface if a menu is called with
dimensions beyond what is supported.

This makes node trees with long links that cross other nodes easier to work with.
Dimmed links will be ignored by various modal operators like cut and reroute insertion.

During initialization of the platform a debug message is generated and
interpreted by de callback. Here the platform is checked what requires
an initialized platform.
Fixed by giving the platform check less priority in the check.
- Added functions to check if the cursor is at a number.
- Added function to parse a number.
- Joined skip_separator functions.
- Added function to check if cursor is at any given set of characters.
AMD Drivers didn't report an additional space in the rendered. This made
testing for the HQ workaround fail and the issue appeared back on
certain cards.
This fix will test with surrounding spaces or if the renderer name
endswith the given string. If any of these are the case the hq normals
workaround will be enabled.
Old implementation has a single parser of many different
formats. With the introduction of Vulkan this would lead
to another parser in the same function. This patch
separates the log parsing using a visitor pattern so the
log parsing can be configured per GPU backend or even
per driver.
With Vulkan we manage the compiler our self so the parsing
will become more straight forward. The OpenGL part depends
on many factors (OS, Driver) and perhaps even GPU.
In preparation of supporting vulkan. Draw/GPU tests should use
GPU_TEST or DRAW_TEST macros. These macros will run the test
on available drawing context backends like OpenGL or Vulkan.
As in master there is only an OpenGL backend nothing changed.
* Mark either all or no class methods with override
* Don't use zero sized array since it has a different size in C and C++.
Using a little more memory here is not significant.
* Don't use deprecated mechanism to mark private GSet members in clang
just like we don't for MSVC, it warns even for simple zero initialization.
Currently the emboss is only fading on left side of the widget,
resulting in the emboss extending vertically on the right side
and ending abruptly. This patch fixes this by also fading the
emboss on the right side and making it symmetric.

One drawback to trying to predict the number of threads that will be
used in the `task_graph` is that we are only sure of the number when the
threads are running.
Using `BLI_task_parallel_range` allows the driver to
choose the best thread distribution through `parallel_reduce`.
The benefit is most evident on hardware with fewer cores.
