For many selection variations we alter the operator's displayed name to
reflect this. For example "Select (Extend)", "Select (Deselect)", and
"Select (Toggle)". This PR does similar for VSE select modes, returning
"Select (Unconnected)", "Select (Linked Time)",
"Select (Linked Handle)", and "Select (Side of Frame)". These are shown
if you press Alt or Ctrl while hovering in the VSE Editor.

The current usage of software-based texture operations in
the oneAPI implementation puts additional register pressure on
the GPU compiler during register allocation. And it also creates
code that requires maintenance. This commit is intended to address
this situation by utilizing a recently productized SYCL bindless
texture API to enable HW-based texture operations using
Intel GPUs' hardware sampler.
This currently translates to 1-11% rendering speedups (scene-specific)
on my Arc A770 and Arc B580. At the moment, there are small
performance regressions with NanoVDB texture operations on Arc B580
and small performance regressions in shade surface MNEE and Raytrace
kernels on Arc A770, but they look recoverable and will be handled
in the future.

There is now a non-experimental API for this_work_item functionality, so
let's use it for better code quality and also to avoid the deprecation
warning during compilation.
No functional or performance changes are expected.

This is due to hardcoded color and subdivision value. Also scale and
offset properties stored in overlay stuct was not considered. Now
multiply the transform matrix with `grid_mat` to make use of these
properties.

Even though from an internal standpoint one could also just use INT
layers (if I understand correctly they are both handled as long?), we
can just support getting/setting bool layers in
the bmesh layer API as well (otherwise, it looks impossible to access
boolean attributes in bmesh).

This `panel->runtime->custom_data_ptr` is `MEM_delete`'d even, so that
was plainfully wrong allocation code.
Will crash in main/4.5 due to PointerRNA now requiring proper C++
construction/destruction.
Use `self` parameter to retrieve the actual 'owner' Main.
Previous code was using G_MAIN, which _should_ be fine in current usage
context, but would for sure break if these functions were to be used
from e.g. a temp Main.

Cleaner and more future-proof. Also refactored slightly the code to make
it more readable.
And removed the 'experimental' warning in docs, this should have been
removed a long time ago.
The Keying Screen and the Anti-Aliasing nodes produce bad results in the
viewport compositor. This is because their cached resources are
allocated from the GPU texture pool, so they might get overwritten.
To fix this, we make sure those are not allocated from the texture pool.
The issue also happens on macOS 15.3.
This is a Metal driver bug, a fix is coming in macOS 15.4. Until then
disable refitting the viewport. There is no perceptible benefit from
refitting, so while it might be less that ideal it allows to side step
the problem and still benefit from the HWRT.

It would both set the dome light color and export a texture with that
same color, which would double up. It was also using the World.exposure
member which is not used anywhere else in Blender.

Intersect mode needs to set everything **outside** of the selection mask
to non-selected and leave the rest untouched.
We already had the comment to "un-set all elements not in the mask" but
that was actually unsetting **everything**.
In theory, we could also early out for `SEL_OP_AND` since the following
`apply_mask_as_` calls are not doing anything for `SEL_OP_AND` really
(but left the change to be minimal).

In setups where only very few elements are processed at once, the lazy-threading
hints that come from `parallel_for` are not triggered. However, often it can
still be worth to use multi-threading in such cases. Therefore, we need to find
additional places where the lazy-threading hints are sent. There are many
possibilities and we probably have to add them step by step as we find .blend
files that show missing multi-threading.
In this patch I choose to send the hint at the beginning of evaluating a repeat
zone if it has 10 or more iterations. The exact number here is just a guess and
could be fine tuned over time if necessary.
A slightly modified version of the file in #134230 speeds up from ~1100ms to
~100ms with this change. The exact speedup changes quite a bit each run, but is
always between 5 and 20x, so it's quite noticable.

Currently, tree, node and socket types are always freed immediately when the
Python code unregisters them. This is problematic, because there may still be
references to those type pointers in evaluated data owned by potentially various
depsgraphs. It's not possible to change data in these depsgraphs, because they
may be independent from the original data and might be worked on by a separate
thread. So when the type pointers are freed directly, there will be a lot of
dangling pointers in evaluated copies. Since those are used to free the nodes,
there will be a crash when the depsgraph updates. In practice, this does not
happen that often, because typically custom node tree addons are not disabled
while in use. They still used to crash often, but only when Blender exits and
unregisters all types.
The solution is to just keep the typeinfo pointers alive and free them all at
the very end. This obviously has the downside that the list of pointers we need
to keep track of can grow endlessly, however in practice that doesn't really
happen under any normal circumstances.
I'm still getting some other crashes when enabling/disabling Sverchok while
testing, but not entirely reliably and also without this patch (the crash there
happens in RNA code). So some additional work will probably be needed later to
make this work properly in all cases.

Previously, all the layers were part of the evaluated state, even if
they were hidden.
Hidden layers should be treated as "disabled" meaning that we should
not evaluate them and/or render them at all.
This fixes this by removing hidden layers from the evaluated data before
layer adjustments and modifier evaluation starts.
As a consequence, hidden layers are no longer accessible in Geometry
Nodes. Technically, this is a breaking change. In the unlikely case that
a user relied on hidden layers to be evaluated within modifiers, they
need to make sure that the layer is visible.

In certain setups where passes are used in the viewport compositor,
blender will crash. This happens because passes may not be available
when the compositor first run but then become available in later runs.
Possibly because EEVEE is still compiling shaders. This is problematic
for the compositor because it caches the result of node tree compilation
for the specific data available, like passes, and the compositor does
not get informed when data becomes available like in the case of EEVEE
to invalidate the cached node tree compilation result.
Caching of node tree compilation was always a source of bugs but we
managed to workaround them in the past, so before we work on a fix for
this crash, we first evaluate the removal of caching to see if we can
live without it. Especially since a fix will be rather involved for the
release branch at this stage.
The time it takes to compile the node tree is:
- Small Tree (~10 nodes): 0.3ms.
- Medium Tree (~50 nodes): 0.6ms.
- Huge Tree (~300 nodes): 3ms.
The difference is not noticeable to the eye, probably since as the tree
becomes bigger, the evaluation time becomes more dominant, and small
trees are fast to compile.
It should be noted that we intended to remove caching in the future to
support things like lazy evaluation of node inputs, but we though a few
optimization needs to be done on the GPUMaterial compiler side to make
compilation faster, since it is the main bottleneck during compilation.
So considering this, I think it is acceptable to disable caching of node
tree compilations for the time being. I intend to optimize it such that
it always becomes less than 1ms, but we will have to delay that to 4.5.

Not really sure why only type and owner_id were cleared here?
Especially when code like `pyrna_struct_CreatePyObject` would check
for both `data` and `type` to be null to consider the pointer as None...
Happens to 'fix' #134311, since now cleared PointerRNA are 'just'
reset to `PointerRNA_NULL`. Would not work if the data was not an
ID PointerRNA though...
NOTE: In general, what is considered an invalid PointerRNA is still very
loosely designed in our code-base, we'll have to address this.

Likely caused by d94a56bdad. In `ANIMDATA_FILTER_CASES` macro,
function call to `animfilter_nla` is not made due to legacy action
condition checks. Since legacy actions are already converted to new
layered action structure in `convert_legacy_animato_actions`, it seems
safe to remove those conditions from macro.

Writing a blend file to a path that references a directory wasn't
being handled correctly.
When the save "versions" was greater than zero the directory would
be renamed (adding a 1), otherwise there would be a
"Version backup failed" error.
Resolve by exiting with an error in the unlikely event the user saves
over a directory.
Part of a fix for #134101.

`environment_mirror_ball.blend` and `image.blend` are both
failling because of mipmap/anisotropic filtering differences
on apple silicon.
The volume tests has issues with lightprobe baking.
Blocking them until we have a workaround.
The `Plane` brush type does not use the original plane/normal
parameters. However, these parameters can be incorrectly retained when
switching type to `Plane` from another brush type where they were
enabled. This commit ensures that they are ignored for the `Plane` brush
type.

The use of `GeometryDeformation` is incorrect for computing the bounds:
It contains _evaluated_ positions for the _original_ points, but does not
match the size of evaluated geometry after constructive modifiers like
Line-Art. For the bounds the evaluated positions should be used as-is.

f0db870822 added support for tree-views to remember state, but only to
remember their custom height for the start. This change makes the scroll
offset be remembered too.
Not remembering the scroll offset can be very annoying in some cases,
e.g. when working with bone collections and changing the active tab in
the properties editor often. In realistic, non-trivial bone collection
set ups this can lead to a lot of repeated scrolling.
Cherry-picked for the 4.4 release since this solves a real usability
issue with trivial changes. Discussed with Thomas and others.
