As described in #135095, this adds a "mirror" option to the "Join as
Shapes" and "Update from Objects" operators, and additional menu items
with the option enabled. Like the operators, this is a convenience
feature that's functionally the same as selecting all shape keys with
changed data and running the existing "Flip" operator.

Pull Request: https://projects.blender.org/blender/blender/pulls/143444
Add a new operator "Make Shape Key the Basis Key", shown in the Shape
Key menu as "Make Basis". Effectively this does the same thing as moving
the active shape key to the top of the list of shape keys: applying it
to the mesh.
This operator is added now, because !141930 will prevent moving shape
keys to the top of the list. This hopefully prevents accidentally making
other keys the basis key, which can cause issues that are hard to
recover from.

**Problem Description**
Blender's current mesh data layout often lacks spatial coherence,
causing performance bottlenecks during BVH construction for sculpting
and painting operations. Each time a BVH is built, the system must
recompute spatial partitioning and vertex groupings from scratch,
leading to redundant calculations and suboptimal memory access patterns.
**Proposed Solution**
This patch implements pre-computed spatial organization of mesh data
through a new `mesh_apply_spatial_organization()` function that:
- Reorders vertices and faces based on spatial locality using recursive
spatial partitioning.
- Stores pre-computed MeshGroup hierarchies in MeshRuntime for reuse.
- Enables the BVH system to bypass expensive spatial computation when
pre-organized data is available.
This approach separates the expensive spatial computation from more
frequent BVH rebuilds, providing sustained performance improvements
across multiple sculpting operations.
**Limitations**
- Requires manual invocation (occurs automatically only during remesh
operations).
- Additional memory overhead for storing MeshGroup metadata.
- One-time computational cost during initial organization.
- Spatial group references are not yet stored in files.
**User Interface**
The feature is accessible via a new "Reorder Mesh Spatially" operator in
the Mesh Data Properties panel under the Geometry Data section. Users
can invoke it manually when needed, or it will be applied automatically
during quadriflow and voxel remesh operations. The operator provides
feedback confirming successful spatial reordering.

The grid layout type for UI list is planned for removal in 5.0, see
blender/blender#110461.
In previous UI meetings, we talked about deprecating the Grid mode of
the UI list, which is not actually accessible in UI and was never used.
Nowadays, there is a new grid view that can be exposed in the API in
the future.
Initially, I wanted to remove references to layout_type in UI templates
in the text editor, because a lot of add-on developers on the
extensions platform base their lists on that code, and a lot of them
are therefore including soon to be deprecated code in their add-ons,
which I want to avoid in the future. But I thought we might as well
remove it from our python scripts as well, since it's just basically
redundant code that doesn't do anything. And also because many add-on
developers use bundled python scripts for references as well.

Relative imports are intentionally avoided in UI code (`scripts/startup/bl_ui`) because it makes it impossible to run individual files in isolation.
Common workflow for making mock-ups and quick UI edits is to load the UI file in Blender's text editor with "Edit Source" operator, make changes, and run the script to see the changes. But in the current version it's impossible because files include relative imports, which don't allow Python to run scripts individually.

This PR adds an Auto Normalize option in the Vertex Group panel that
when checked will normalize the other deform-bone vertex groups' weights
when assigning the weight of a deform-bone vertex group. For example if
a selected vertex has the following weights:
| Name | Weight |
|---------|--------|
| Group 1 | 0.2 |
| Group 2 | 0.2 |
| Group 3 | 0.6 |
And the user selects Group 3, checks the Auto Normalize checkbox, sets
the weight to 0.8, and clicks Assign, the new weights will be:
| Name | Weight |
|---------|--------|
| Group 1 | 0.1 |
| Group 2 | 0.1 |
| Group 3 | 0.8 |

This operator is very similar to the existing "Join as Shapes" operator,
which updates or adds shape key array values with the positions of
objects with the same name, but instead of creating new shape keys,
it just updates existing ones. The new operator is called "Update from
Objects" in the UI.
Internally, some logic was moved to a poll function shared between the
two operators, and a new argument for whether to ensure keys exist was
added to their shared implementation.

Adds vertex groups and basic operator support to the `GreasePencil` data
block.
Vertex groups in the `GreasePencil` ID are used as the source of truth
for vertex groups names and ordering in the UI. Individual drawings also
have vertex group lists, but they should not be modified directly by
users or the API. The main purpose of storing vertex group names in in a
drawing's `CurveGeometry` is to make it self-contained, so that vertex
weights can be associated with names without requiring the
`GreasePencil` parent data.
Vertex group operators are implemented generically for some ID types.
Grease Pencil needs its own handling in these operators. After
manipulating `vertex_group_names` the `validate_drawing_vertex_groups`
utility function should be called to ensure that drawings only contain a
true subset of the `GreasePencil` data block.
Operators for assigning/removing/selecting/deselecting vertices are also
implemented here. To avoid putting grease pencil logic into the generic
`object_deform.cc` file a number of utility functions have been added in
`BKE_grease_pencil_vgroup.hh`.

It is very common for graphical editors with layers to support
locking individual layers to protect them from accidental edits due
to misclicks. Blender itself already supports locking vertex groups.
This adds lock toggles for shape keys, with lock/unlock all operators.
The flags are checked by sculpt brushes, edit mode transform tools,
and Smooth, Propagate and Blend From Shape operators. This selection
aims to cover operations that only deform the mesh, where the shape
key selection matters.
Topology changing operations always apply to all keys, and thus
incorrect shape key selection is less impactful. Excluding them
from the new feature greatly reduces the patch size.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Currently we have options to transfer the paint mask, face sets, and
color attributes to the new mesh created by voxel remesh. This doesn't
make use of the generic attribute design, where it would be clearer to
transfer all attributes with the same methods. That's reflected in the
code as well-- we do duplicate work for the mask and vertex colors, for
example.
This commit replaces the transfer options with a single checkbox for
all attributes. All attribute types on all domains are transferred with
basically the same method as the "Sample Nearest" node from geometry
nodes-- they take the value from the nearest source element of the same
domain. Face corners are handled differently than before. Instead of
retrieving the mixed value of all the corners from the nearest source
vertex, the value from the nearest corner of the nearest face.

Some timing information, showing that when interpolating the same
data, the attribute propagation is significantly faster than before.
Edge and corner attributes would add some cost (edges more than
corners), but might not always be present.

This PR replaces the auto smooth option with a geometry nodes modifier
that sets the sharp edge attribute. This solves a fair number of long-
standing problems related to auto smooth, simplifies the process of
normal computation, and allows Blender to automatically choose between
face, vertex, and face corner normals based on the sharp edge and face
attributes.
Versioning adds a geometry node group to objects with meshes that had
auto-smooth enabled. The modifier can be applied, which also improves
performance.
Auto smooth is now unnecessary to get a combination of sharp and smooth
edges. In general workflows are changed a bit. Separate procedural and
destructive workflows are available. Custom normals can be used
immediately without turning on the removed auto smooth option.
**Procedural**
The node group asset "Smooth by Angle" is the main way to set sharp
normals based on the edge angle. It can be accessed directly in the add
modifier menu. Of course the modifier can be reordered, muted, or
applied like any other, or changed internally like any geometry nodes
modifier.
**Destructive**
Often the sharp edges don't need to be dynamic. This can give better
performance since edge angles don't need to be recalculated. In edit
mode the two operators "Select Sharp Edges" and "Mark Sharp" can be
used. In other modes, the "Shade Smooth by Angle" controls the edge
sharpness directly.
### Breaking API Changes
- `use_auto_smooth` is removed. Face corner normals are now used
automatically if there are mixed smooth vs. not smooth tags. Meshes
now always use custom normals if they exist.
- In Cycles, the lack of the separate auto smooth state makes normals look
triangulated when all faces are shaded smooth.
- `auto_smooth_angle` is removed. Replaced by a modifier (or operator)
controlling the sharp edge attribute. This means the mesh itself
(without an object) doesn't know anything about automatically smoothing
by angle anymore.
- `create_normals_split`, `calc_normals_split`, and `free_normals_split`
are removed, and are replaced by the simpler `Mesh.corner_normals`
collection property. Since it gives access to the normals cache, it
is automatically updated when relevant data changes.
Addons are updated here: https://projects.blender.org/blender/blender-addons/pulls/104609
### Tests
- `geo_node_curves_test_deform_curves_on_surface` has slightly different
results because face corner normals are used instead of interpolated
vertex normals.
- `bf_wavefront_obj_tests` has different export results for one file
which mixed sharp and smooth faces without turning on auto smooth.
- `cycles_mesh_cpu` has one object which is completely flat shaded.
Previously every edge was split before rendering, now it looks triangulated.

Avoid an error when drawing the Lattice properties panel. The code for
drawing mesh attributes warnings didn't account for the fact that lattices
also have vertex groups, and thus that particular code can be called
without an active mesh.
So far, only the attribute panel showed a warning when there were duplicate
attribute names. This patch adds the same warning to the vertex groups,
color attributes and uv maps panel. All of these attributes are in the same
namespace from the perspective of geometry nodes. Name collisions should
be avoided to so that ambiguities when referencing attributes don't come up.
With #112889, vertex groups can have the same name as other attributes again.
While we can handle this case somewhat gracefully in general, duplicate names
likely lead to problems down the line, so it's better if they can be avoided early.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:

Store subdivision surface creases in two new named float attributes:
- `crease_vert`
- `crease_edge`
This is similar to 2a56403cb0.
The attributes are naming conventions, so their data type and domain
aren't enforced, and may be interpolated when necessary. Editing tools
and the subdivision surface modifier use the hard-coded name. It might
be best if these were edited as generic attributes in the future, but
in the meantime using generic attributes helps.
The attributes are visible in the list, which is how they're now meant
to be removed. They are now interchangeable with any tool that works
with the generic attribute system-- even tools like vertex paint can
affect creases now.
This is a breaking change. Forward compatibility isn't preserved for
versions before 3.6, and the `crease` property in RNA is removed in
favor of making a smaller API surface area with just the attribute API.
`Mesh.vertex_creases` and `Mesh.edge_creases` now just return the
matching attribute if possible, and are now implemented in Python.
New functions `*ensure` and `*remove` also replace the operators to
add and remove the layers for Python.
A few extrude node test files have to be updated because of different
(now generic) attribute interpolation behavior.

Face maps were added as a prototype of a new rigging solution during
2.8 development. Their storage is redundant with the newer generic
attribute system (specifically with integer face attributes), and
they were never used much. This commit removes the face map list
and converts the storage to an attribute with the name `face_maps`.
There is nowhere to store the face map names anymore, so those
are not kept.
It probably still makes sense to have a feature like mesh face gizmo
selection for rigging. But the design and implementation woulds likely
have to change significantly, including possibly changing the storage
type, and making use of the generic attribute system instead of a
special type.
See #105317 for more discussion.
Store bevel weights in two new named float attributes:
- `bevel_weight_vert`
- `bevel_weight_edge`
These attributes are naming conventions. Blender doesn't enforce
their data type or domain at all, but some editing features and
modifiers use the hard-coded name. Eventually those tools should
become more generic, but this is a simple change to allow more
flexibility in the meantime.
The largest user-visible changes are that the attributes populate the
attribute list, and are propagated by geometry nodes. The method of
removing this data is now the attribute list as well.
This is a breaking change. Forward compatibility is not preserved, and
the vertex and edge `bevel_weight` properties are removed. Python API
users are expected to use the attribute API to get and set the values.
