- Prefix comments before members is used practically everywhere,
remove C99 syntax from inside comments.
- Replace double quotes with backticks for code styling.
For historical reasons, the `multi_input_socket_index` was actually reversed
(large index comes first). This patch renames it to `multi_input_sort_id` and
adds a comment. This new name makes it less confusing that the id is reversed.

It seems that the compiler on windows struggled to
correctly assign the namespace of the `LocalMemArena`
destructor because the struct was defined locally
in a lambda.
This moves the struct definition out of the lambda.
Fix a crash when inserting a key with tweak mode enabled, but where
`AnimData::actstrip` was NULL.
The root cause of this is that two pointers in the `AnimData` struct
(`act_track` and `actstrip`) are expected to be set when NLA tweak mode
is enabled, BUT these are not exposed to RNA and thus invisible to the
library overrides system. As such, they are NULL when loading from disk,
while the `ADT_NLA_EDIT_ON` flag still indicates they are to be used.
Rather than adding a NULL pointer check (and having to add that in many
more places), I used this two-pronged approach:
- Extend the 'NLA tweakmode' override apply code, to set the `act_track`
and `actstrip` pointers when they are incorrectly NULL. This is done
by lookup of the track and strip by name.
- Add versioning code to exit out of tweak mode whenever the
`ADT_NLA_EDIT_ON` flag is set, but those two pointers are still NULL.
The last step was necessary with the example file attached to the bug
report, as that was saved with a buggy blender version. New saves work
just fine.

This became a bottleneck in one of the test files during playback.
A grease pencil object was using an array modifier which tags the triangle
caches to be invalidated. Then it re computed the fills on every frame, which
was slow (when single threaded).
With this patch, the playback went from ~43fps to 60+fps.

If the bevel "Harden Normals" option is on, custom normals will be
generated. In that case, the automatic sharp edge tagging based on the
angle shouldn't run. This PR extends the earlier fix to #116395 to
handle this case and also extends the check to not just check the last
modifier, which doesn't work in this test file which has a collision
modifier at the end. That makes sense anyway, since what we really care
about is whether the evaluated mesh has custom normals or not.

This PR fixes several issues with the versioning that replaces the old
auto smooth flag with a modifier.
One issue is that the flag wasn't cleared in the initial versioning
code. That means some objects have the replacement modifier but their
meshes still have the flag set. The fix for that is to make the
versioning idempotent by trying to find an existing node group before
adding a new one. The versioning is now re-run on all objects to clear
the flags. Flags on all meshes are cleared too, even unused meshes.
That could cause loss of the auto-smooth when the mesh is linked from
a different blend-file, but that situation should be very rare.
Another issue was that the versioning wasn't run when linking objects.
That was simple to solve by adding the versioning where the proxy
versioning already existed for that case.
Finally, arguably the largest issue was that the the newly added node
groups were always added as local data-blocks. When linking, having
library data-blocks point to local data-blocks not in that library is
quite bad and breaks assumptions around Blender. This is solved by
having an auto smooth node group per library.

If a bone was specified (but now missing), the driver would fallback to
using the object as a target (which can lead to unintended behavior).
So now check if a bone is specified, if it is missing, mark the driver
invalid. If no bone is specified at all, then use the armature object as
the target.
NOTE: `DTAR_FLAG_INVALID` is not granular enough to distinguish the
object and bone targets, so both will be marked in red in the UI (there
is already comments about it in code). If necessary, we could introduce
an additional DTAR_FLAG_BONE_INVALID and use that in a couple of places.

This reverts commit c6497dd9f7.
This wasn't working the way I expected, it seems the LIB_TAG_NEW isn't
set here. Better to address the fundamental issues anyway. Sorry for
the noise.
When appending objects from an older file, versioning needs to run to add
an auto smooth modifier if necessary. However, this was running for all
objects rather than just the newly appended objects. It's quite wrong to
modify existing objects here, so add an explicit check for that. This could
improve performance as well, but skipping checks for objects when
the work is unnecessary.
The crash will hopefully be resolved by other improvements to the auto
smooth versioning (making it properly idempotent and running it again
should fix the problem with the hidden legacy flags still set). But I still think
this PR is worth committing, to be very explicit about only modifying new
objects in versioning code.

Previously I misunderstood the subsurf modifier's handling of custom
normals. The "use custom normals" check in 4.0 checked if there were
custom normals and whether the auto smooth flag was checked. I wrongly
changed that to check the mesh normals domain instead of whether there
was custom normals. In 4.1, auto smooth isn't required to use custom
normals, but that should be the only change here.
In this PR, that change is done for CPU and GPU subdivision, and for
the versioning which adds a modifier. The versioning now only puts the
new modifier before the subsurf modifier if it would have used the
custom normals interpolation in 4.0.
The last change causes two test failures which I also misunderstood
before. The previous results were arguably incorrect, because the
Cycles experimental adaptive subdivision ignored the auto smooth
angle, which was 5 degrees. It should have been 180 degrees.
I will modify those test files to remove auto smooth from the meshes.

This adds conversion for the following flags:
- `GREASE_PENCIL_ANIM_CHANNEL_EXPANDED`
- `GREASE_PENCIL_AUTOLOCK_LAYERS`
- `GREASE_PENCIL_STROKE_ORDER_3D`
Note: The last two are not expose through the UI yet.
This fixes an issue where the `use_masks` functions on layers
and groups returned the wrong value.
The issue was that the root group doesn't have this flag set
which then propagates to all the layers and groups.
To fix this we invert the `GP_LAYER_TREE_NODE_USE_MASKS` flag (now called `GP_LAYER_TREE_NODE_HIDE_MASKS`).
The API still uses the `use_masks` function.
Layer masks were partly already there. This PR completes the implementation and expose them through the UI.
This also adds three operators to:
- add a layer mask
- remove a layer mask
- reorder layer masks
Note: These are not used by the renderer yet. Will be done in a following PR.

This adds the `viewlayername` property to grease pencil v3 layers.
It's exposed as `viewlayer_render` in python.
Note: this is not used in the renderer yet. Will be used in a following PR.

- Remove the unnecessary `ContainerValue` from the class hierarchy
- Construct `StringValue` with a `std::string` by value to avoid copies
- Remove some indirection by using type names directly instead of aliases
- Use utility methods to lookup/append specific data types for arrays/dicts
- Simplify conversion from unique_ptr to shared_ptr
- Avoid use of `new` and `delete`
- Avoid creating maps of all elements in vector for a single lookup
The Weighted Normal modifier has a "Keep Sharp" option that used to
recalculate the sharp edge tags based on the mesh's smoothing angle.
To keep the same behavior, an auto smooth versioning modifier has to
be added before that modifier when the option is on.

Unfortunately the only versioning code that can "properly" add data-
blocks is not run when linking or appending (`do_versions_after_setup`
has details). The versioning has to be done manually for this case.
Fortunately that is simple since the versioning function already just
operators on a main database.
With some data-type conversions we can do a best-effort conversion of
UI data like default values and min and max to the new data type.
This can help to make Python scripts simpler and to avoid bugs like
#105965.

The core of the issue was that `sculpt_flag` was used by three different enums (`eGP_Sculpt_Flag`, `eGP_Sculpt_Mode_Flag`, and `eBrushFlags`). This resulted in the flag getting overriden because `ENUM_OPERATORS` expected the maximum value of `eGP_Sculpt_Flag` to be `(1 << 3)` which it wasn't.
The `sculpt_flag` was exposed through python as `"direction"`.
In the UI this meant that it was effectively used as `brush.direction`. This fix replaces `brush.gpencil_settings.direction` with `brush.direction`.
It also makes sure `sculpt_flag` is only ever used with values from `eGP_Sculpt_Flag`.

The function didn't return early in case the domain was empty.
The fix makes sure we return an empty `MutableSpan` in this case
(add doesn't try to create a new custom data layer).
Grease Pencil provides custom vertex group attributes as VArrays that
are a view on the `MDeformVert` buffer. These attributes are not spans,
which the curve conversion code was expecting. Non-span VArrays must be
materialized first.

There seems to be an integer overflow in OpenVDB code. For now just avoid rendering

Header file is renamed to GEO_mesh_boolean_convert.cc and

This is in preparation for bigger changes to the internal

than a kernel API.
