This issue was introduced in rB78f28b55d39288926634d0cc.
The fix is to use a `std::shared_ptr` to ensure that the `Global` will live
long enough until all `Local` objects are destructed.
This patch adds a new "Kernel Optimization Level" dropdown menu to control Metal kernel specialisation. Currently this defaults to "full" optimisation, on the assumption that the changes proposed in D16371 will address usability concerns around app responsiveness and shader cache housekeeping.

All kernel specialisation is now performed in the background regardless of kernel type, meaning that the first render will be visible a few seconds sooner. The only exception is during benchmark warm up, in which case we wait for all kernels to be cached. When stopping a render, we call a new `cancel()` method on the device which causes any outstanding compilation work to be cancelled, and we destroy the device in a detached thread so that any stale queued compilations can be safely purged without blocking the UI for longer than necessary.

Both, the guarded and lockfree allocator, are keeping track of current
and peak memory usage. Even the lockfree allocator used to use a
global atomic variable for the memory usage. When multiple threads
use the allocator at the same time, this variable is highly contended.
This can result in significant slowdowns as presented in D16862.
While specific cases could always be optimized by reducing the number
of allocations, having this synchronization point in functions used by
almost every part of Blender is not great.
The solution is use thread-local memory counters which are only added
together when the memory usage is actually requested. For more details
see in-code comments and D16862.

WLROOTS compositors don't run surface leave callbacks,
while this may be considered a bug in WLROOTS, neither GTK/SDL crash
so workaround the crash too.
This also fixes a minor glitch where the cursor scale wasn't updated
when changing monitor scale at run-time.
This functionality is related only to debugging of SYCL implementation
via single-threaded CPU execution and is disabled by default.
Host device has been deprecated in SYCL 2020 spec and we removed it
in 305b92e05f.
Since this is still very useful for debugging, we're restoring a
similar functionality here through SYCL 2020 Host Task.
The "osl_texture" intrinsic was not implemented correctly. It should handle alpha
separately from color, the number of channels input parameter only counts color
channels.
This panel showed a duplication of options that were in the main light panel and only mistakenly shows up in the workbench engine where lights should have no options.
This panel was also used by the POV-Ray add-on but that was removed recently.
This reverts commit a3a9459050.
And fixes T103337.
a3a9459050 has some flaws and it needs to go through review (See D16803).

The problem here is that the previous barycentric clamping did not deal well
with skinny triangles and would end up generating "sub-pixel jittering"
locations that were actually >20 pixels away.

Materials without connections to the output node would crash with OSL
in OptiX, since the Cycles `OSLCompiler` generates an empty shader
group reference for them, which resulted in the OptiX device
implementation setting an empty SBT entry for the corresponding direct
callables, which then crashed when calling those direct callables was
attempted in `osl_eval_nodes`. This fixes that by setting the SBT entries
for empty shader groups to a dummy direct callable that does nothing.
Switching viewport denoising causes kernels to be reloaded with a new
feature mask, which would destroy the existing OptiX pipelines. But OSL
kernels were not reloaded as well, leaving the shading pipeline
uninitialized and therefore causing an error when it is later attempted to
execute it. This fixes that by ensuring OSL kernels are always reloaded
when the normal kernels are too.
Recent reverting of changes to cursor grabbing intended to match
Blender 3.3 release. This is the case for 3.4x branch, however there is
an additional change to grabbing on WIN32 by Germano [0] which is a
significant improvement on old grabbing logic for Windows.
So instead of matching 3.3x behavior, restore logic that keeps
the cursor centered while grabbing & hidden.
This re-introduces T102792 issue displaying the paint-brush while
dragging buttons, this will have to be solved separately.
Re-apply [1] & [2], revert [3] & [4].

Replace ../lib/linux_centos7_x86_64 with ../lib/linux_x86_64_glibc_228,
built with Rocky8 Linux, compatible with the VFX platform CY2023,
see: T99618.
- Update build-bot configuration.
- Remove unnecessary check for Blosc, this is part of OpenVDB lib now.
- Remove WITH_CXX11_ABI, always use new C++11 ABI now
- Replace centos7 by glibc_228 everywhere
Note that existing builds with cached paths pointing to
"../lib/linux_centos7_x86_64" will need to be updated.

Under Wayland the transform cursor wasn't displaying the warped cursor.
This worked on other platforms because cursor motion is warped where as
Wayland simulates cursor warping, so it's necessary to apply warping
when requesting the cursor location too.
This reverts commits
9fd6dae793,
4cac8025f0 (minor cleanup).
Re-introducing T102346, which will be fixed in isolation.
Unfortunately even when the cursor is hidden & grabbed,
the underlying cursor coordinates are still shown in some cases.
This caused bug where dragging a button in the sculpt-context popup
would draw the brush at unexpected locations because internally
the cursor was warping in the middle of the window, reported as T102792.
Resolving this issue with the paint cursor is possible but tend towards
over-complicated solutions.
Revert this change in favor of a more localized workaround for walk-mode
(as was done prior [0] to fix T99021).

This is a solution in response to the issues mentioned in comments on
rBe4f1d719080a and T103088.
Apparently the workaround of checking if the mouse is already inside
the area on the next event doesn't work for some tablets.
Perhaps the order of events or some very small jitter is causing this
issue on tablets. (Couldn't confirm).
Whatever the cause, the solution of checking the timestamp of the event
and thus ignoring the outdated ones is theoretically safer.
It is the same solution seen in MacOS.
Also calling `SendInput` 3 times every warp ensures that at least one
event is dispatched.
This adds a new mirror image extension type for shaders and
geometry nodes (next to the existing repeat, extend and clip
options).
See D16432 for a more detailed explanation of `wrap_mirror`.
This also adds a new sampler flag `GPU_SAMPLER_MIRROR_REPEAT`.
It acts as a modifier to `GPU_SAMPLER_REPEAT`, so any `REPEAT`
flag must be set for the `MIRROR` flag to have an effect.

The `render_color_index` skips attributes with different types
and domains in order to give the proper order for the UI list.
That is a different than an index in the group of all attributes.
The most solid solution I could think of is exposing the name of
the default color attribute. It's "solid" because we always address
attributes by name internally. Doing something different is bound
to create problems. It's also aligned with the design in T98366 and
D15169.
Another option would be to change the way the "attribute index"
is incremented in Cycles. That would be a valid solution, but would
be more complex and annoying.
For consistency, I also exposed the name of the active color attribute
the same way, though it isn't necessary to fix this particular bug.
The properties aren't editable, that can come in 3.5 as part of D15169.

This is done based on the render sample count so that it doesn't impact
sampling quality. It's similar in spirit to the adaptive table size in D16561,
but in this case for performance rather than memory usage.

The first two dimensions of scrambled, shuffled Sobol and shuffled PMJ02 are
equivalent, so this makes no real difference for the first two dimensions.
But Sobol allows us to naturally extend to more dimensions.
Pretabulated Sobol is now always used, and the sampling pattern settings is now
only available as a debug option.
This in turn allows the following two things (also implemented):
* Use proper 3D samples for combined lens + motion blur sampling. This
notably reduces the noise on objects that are simultaneously out-of-focus
and motion blurred.
* Use proper 3D samples for combined light selection + light sampling.
Cycles was already doing something clever here with 2D samples, but using
3D samples is more straightforward and avoids overloading one of the
dimensions.
In the future this will also allow for proper sampling of e.g. volumetric
light sources and other things that may need three or four dimensions.
