There is a bug in Embree that makes BVH updates crash. Disabling multithreaded
BVH updates after the initial BVH build appears to work around it, at the cost
of some performance.
This will not affect performance of the initial BVH build, transforming objects
or editing a single mesh. It will only affect performance when multiple smaller
meshes are edited together, as those can no longer have their BVH updated in
parallel or benefit from parallellization over many primitives.

Remove an overly-careful check on an enum value being greater than zero.
The check was added back in the day when this value was declared as
`int` and thus could easily be assigned anything.
The check for the upper limit was kept, and augmented with a
`BLI_assert()` so that failures here will actually go noticed and can
get fixed.
No actually functional changes. The data being checked is purely
runtime, and is assumed to be generated correctly already.

Expose the convenience function `blender::animrig::action_fcurve_ensure()`
to RNA as `Action.fcurve_ensure_for_datablock(...)`.
The function requires that the Action is already assigned to the
data-block. It then takes care of slot assignment / creation, as well as
the creation of a layer and a keyframe strip.
This function call:
```python
fcurve = action.fcurve_ensure_for_datablock(ob_cube, "location", index=2)
```
effectively performs this logic:
```python
# Ensure the slot exists and is assigned:
slot = ob_cube.animation_data.slot
if not slot:
slot = find_slot_for_keying(action)
if not slot:
slot = action.slots.new(ob_cube.name)
ob_cube.animation_data.slot = slot
# Ensure a layer exists:
if action.layers:
layer = action.layers[0]
else:
layer = action.layers.new("Layer")
# Ensure a keyframe strip exists:
if layer.strips:
strip = layer.strips[0]
else:
strip = layer.strips.new('KEYFRAME')
# Ensure the channelbag exists:
channelbag = strip.channelbag(slot, ensure=True)
# Ensure the F-Curve exists:
fcurve = channelbag.fcurves.find("location", index=1)
if not fcurve:
fcurve = channelbag.fcurves.new("location", index=1)
```
Here `find_slot_for_keying()` represents the logic that's also used when
creating keys via the user interface or the `bpy_struct.keyframe_insert()`
function.

Update the Action RNA descriptions, to clarify which parts of the API are
considered legacy. These will only act on the action's first slot, in an
attempt to be backward-compatible with the pre-4.4 (non-slotted) actions.
No actual functional changes, just a change in the descriptions.

New version of b22670d927 (which was reverted with 9d33dd88d5).
I rather keep `uiHandleButtonData` private to the handling code. It
does the allocation as part of its implementation details, so it should
also handle freeing.
Add a `--profile-gpu` launch argument.
When set, it generates a profile in the Trace Event Format with CPU and
GPU metrics based on GPU debug scopes.
https://profilerpedia.markhansen.co.nz/formats/trace-event-format/
The profiles are best viewed at https://ui.perfetto.dev/
Notes:
- The profiler captures everything form app start to exit.
- Being JSON based the profiles can become relatively large, but they
compress very well.
- Only OpenGL profiling is supported for now, but the report formatting
code can be shared across backends.

Add a dedicated callback to duplicate the key for each type.
Keeping changes to the minimum necessary ones, the whole code and data
structure could use a serious update using C++ features, but this would
be totally out of scope of this fix.

Instead of passing the `scene`, pass a pointer to the `Editing` struct.
This is the struct that owns the `StripLookup` in its `runtime`
so there isn't a good reason to use the `scene` pointer here
anyways.

Plotting happens from the given root node into a graphviz file.
Supports plotting from both scene level LightTreeNode and the kernel
level KernelLightTreeNode.
An external graphviz command is to be used to convert generated file
to an image.

This reverts commit afec64739a.
The commit introduces a regression where opening the Asset Browser opens
the File Browser instead, same for other editor sub-types, see
blender/blender#134630.
blender/blender!134642 proposes a different solution and reverts this,
which I prefer too. Better to the revert separately from trying a
different fix for the initial bug, makes reviewing easier too.
This removes the `scene` parameter of
`SEQ_time_get_rounded_sound_offset` and
`SEQ_time_media_playback_rate_factor_get`.
Instead, we now pass the `frames_per_second` directly.
This is an attempt at getting less of the code to be
scene dependent.

This main thread check was introduced in 4536a4c610. At the time OpenGL
only ever worked in the main thread, but that limitation was lifted in
Blender 2.80.
With this operator being converted to use the jobs system, it now needs
to work in non-main threads. Note that this code does not run in parallel
with main thread drawing anyway, because of WM_job_main_thread_lock_acquire
and draw manager locks. What changed is that we can now activate OpenGL
contexts on other threads.

The original report stumbled upon this issue with a more tricky
configuration when light linking is combined with light tress.
However, the actual contributing factor was a mesh with emission
shader which is not assigned to any triangles. This triggered a
bug in the BoundBox::transformed() which converted non-valid bounds
to bounds by performing per-corner growing.
Additionally fix incorrect handling of shared nodes which only
worked for leaf nodes. This was due to the fact how the measure
was accumulated: it is possible that add() is called with an empty
measure.

`DEGCustomDataMeshMasks` makes `IDInfo` struct non-trivial, so it should
not be allocated or freed with C-style allocation.
Instead of allocating this data, now use its only persistent user
(the `DepsgraphNodeBuilder::id_info_hash_` map) as owner, move the rest
of the code releasing COW IDs to a new destructor for `IDInfo`, and let
standard C++ destruction do the job.
NOTE: This change seems to give some performances improvements in
affected code (e.g. about 4% improvement in affected area of
`DepsgraphNodeBuilder::begin_build`). However, this does not affect global
performances in a measurable way.
Related to work on improving our memory allocation code in !134463.

As announced in <LINK_TO_DEVTALK_POST> (*[proposed post](https://hackmd.io/@s3W_pRGTTXie8cKWRitZrA/S1SzUhqIkl)*), Big Endian support will be
fully removed from Blender 5.0.
This commit adds deprecation warning when opening such blendfiles, and a
static `#warning` when building on a Big-Endian system.
Implements 4.5-part of #125759.
Add `PointerRNA::reset()` and `PointerRNA::invalidate()` utils functions
(both simply reset the PointerRNA data to empty state).
Replace `RNA_POINTER_INVALIDATE` macro by `PointerRNA::invalidate()`.
Follow-up to !134393 and e55d478c64.

`UI_BTYPE_CURVEPROFILE` button has undo flag set. see button-layout in:
`edbm_bevel_ui() -> uiTemplateCurveProfile()`.
This forces an undo push with the help of `ui_apply_but_undo/ui_apply_but_funcs_after`.
To handle the situation, skip undo push for buttons in hud region.

The issue was that with the move to Grease Pencil v3,
annotations and normal GP use different IDs and support to show annotations
wasn't added back in.
This makes it so annotation keys are shown if "Only Show Selected" is disabled,
which works in the Dope Sheet and in the timeline.
In order to not show annotations of the scene twice, the scene-specific code is removed.
The annotations are now shown in a more generic way.

This reverts 06a2617107.
Commit has introduced few errors from user perspective (#134277) and
python side (#134380). Best to revert it now then handle the bug fixes later.
The error in #134380 was due to `context.layer_collection` and
`active_layer_collection` returning excluded collection.

Nothing but improvements to comments in this area of code to better
explain the complexity of Emum list row and column calculation. These
things change wrapping and column count to suit available space and
needs better explanation.
Pull Request: https://projects.blender.org/blender/blender/pulls/134719
For non-categorized lists, rather than always trying to find optimal
rows and columns, revert to prior behavior and only reflow if needed,
when the calculated rows are greater than maximum rows. This is less
disruptive, has less changes at small sizes where this doesn't matter.
Yet still does the job when things get too large to fit, or the list
is very long.
