This includes a new list structure type and socket shape, a node
to create lists, a node to retrieve values from lists, and a node to
retrieve the length of lists. It also implements multi-function support
so that function nodes work on lists.
There are three nodes included in this PR.
- **List** Creates a list of elements with a given size. The values
are computed with a field that can use the index as an input.
- **Get List Item** A field node that retrieves an element from a
a list at a given index. The index input is dynamic, so if the input
is a list, the output will be a list too.
- **List Length** Just gives the length of a list.
When a function node is used with multiple list inputs, the shorter
lists are repeated to extend it to the length of the longest.
The list nodes and structure type are hidden behind an experimental
feature until we can be sure they're useful for an actual use case.

This patch replaces the Composite node with the Group Output node as the
primary compositor output. The old node was removed and versioned. This
was done for consistency with Geometry Nodes and in preparation for more
generic use of the compositor in VSE modifiers, layered compositing, NPR
multi-stage compositing, and more.
The Group Output node relies on the node tree interface, so we now have
a default interface of a single input and a single output. For now, only
the first input is considered while the rest are ignored, just like the
Geometry Nodes design. Furthermore, the input is required to be of type
color. Warnings and errors are issues if any of those are not met, also
similar to Geometry Nodes.
This introduces a new limitation: Composite outputs can no longer exist
in node groups, since they obviously then act as their respective group
outputs.
A refactor for the compositor scheduler is needed to simplify the logic
after this change, but this will be done in a separate patch.

If importing keymap with the same name as the built-in ones (like
"Blender", "Industrial Compatible"), those entries will become stale and
can't be removed from the UI because when removing preset it checks the
name against builtin ones. This patch fixes the problem from the
importing side and disallow names that are the same with builtin ones
from being imported (They will be renamed upon importing).

HDR video files are properly read into Blender, and can be rendered out
of Blender.
HDR video reading / decoding:
- Two flavors of HDR are recognized, based on color related video
metadata: "PQ" (Rec.2100 Perceptual Quantizer, aka SMPTE 2084) and
"HLG" (Rec.2100 Hybrid-Log-Gamma, aka ARIB STD B67). Both are read
effectively into floating point images, and their color space
transformations are done through OpenColorIO.
- The OCIO config shipped in Blender has been extended to contain
Rec.2100-PQ and Rec.2100-HLG color spaces.
- Note that if you already had a HDR video in sequencer or movie clip,
it would have looked "incorrect" previously, and it will continue to
look incorrect, since it already has "wrong" color space assigned to
it. Either re-add it (which should assign the correct color space),
or manually change the color space to PQ or HLG one as needed.
HDR video writing / encoding"
- For H.265 and AV1 the video encoding options now display the HDR mode.
Similar to reading, there are PQ and HLG HDR mode options.
- Reference white is assumed to be 100 nits.
- YUV uses "full" ("PC/jpeg") color range.
- No mastering display metadata is written into the video file, since
generally that information is not known inside Blender.

When creating presets in some panels, names like "Default" can be used
which are the same preset names as bundled presets. New entries created
like this can't be deleted because blender will treat it as a bundled
preset which then leaves stale entries in the list. This fix prevents
those kind of preset names to be used during creation.

When having a checkbox and a value both in one row together with an
animation decorator it is questionable whether the decorator should act
on animating the checkbox or the corresponding value.
We had similar cases before (e.g. 7c04ef210e)
In this case as well, one would think it is more desirable to animate
the actual Temperature **value** (instead of the checkbox), so this is
what this PR does.

This commit moves the freestyle edge and face mark tags to become
generic attributes, similar to other changes over the past years. The
attributes are called "freestyle_edge" and "freestyle_face", and they're
now propagated like regular boolean attributes.
Compatibility wise, forward and backward blend file compatibility are
maintained (for forward compatibility this is implemented a bit
differently than in the past because of the ongoing `AttributeStorage`
transition). In the Python API, `use_freestyle_mark` has been removed;
the attribute API should be used instead (just like bevel weights).
The BMesh (`freestyle`) accessors are removed too.
The conversions benefit from the fact that bit-wise, the old structs are
the same as `bool`, so we can convert to the old and new formats without
reallocating arrays.

Panel toggles are implemented by having a boolean socket with
`is_panel_toggle` set to `True`, as the first item in that panel's children.
These sockets are then hidden from the user, as the checkbox gets drawn
in the panel's UI.
In specific circumstances described in the bug report, the active selection
can sometimes land on these sockets. Leading to the user being able to
directly access these internal sockets.
The changes in the patch make the "Remove Item" operator check if
the resulting selection lands in a toggle socket, and move the selection
to that toggle's parent panel if that is the case.

Some items in the node editors' add menus were not properly
translated. The affected items referenced an enum property on a node,
such as Math node's Operation.
Since some of those enums use a specific translation context, the same
context must be used when adding them to the search menus. The context
can simply be retrieved from the bl_rna prop itself.
In addition, some items use labels that are already translated
manually and do not need the auto translation, so disable that in
those cases (translate=False).
No new messages are added by this change.

Instead of only showing a button to switch to the texture properties -
which don't actually allow creating a texture for linestyle - add a
data-block selector that allows creating a texture for linestyle. It
will also show a button to switch to the texture properties, if
available.
It seems like the previous UI didn't have any good way of assigning a
texture for linestyle, without going into the texture node editor.

**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.

You could basically not interact with the animation (except for
keyframes in the main region), channels region was totally empty, NLA
could not be used, ...
It is not something users will animate a lot, but we should still have
animation editors in mind when adding a new object type.

allowing this to be able to search collection to move and to expand
this menu from other menus.
This removes the expected memory leak of using the popup.

Geometry Nodes' Add > Input > Import menu includes file format items
such as "Standford PLY (.ply)", "STL (.stl)", "Text (.txt)". The
latter needs to be translated because "Text" is a generic format.
These items are declared using a custom function
`node_add_menu.add_node_type`, with a `label` argument. This commit
adds the `label` argument to the function arguments that can be
extracted from specific node declaration functions, and specifies the
argument position for each:
"add_node_type", "add_node_type_with_outputs", "add_simulation_zone",
"add_repeat_zone", "add_foreach_geometry_element_zone",
"add_closure_zone".
There is currently no facility to specify a translation context but it
could be easily added if the need arises.
Most of these functions do not actually declare new, unique messages,
but it could happen in the future. In addition, two messages were
extracted using manual `iface_()` calls, which are no longer needed
after this change.
Reported by Ye Gui in #43295.
This commit introduces the `radial_symmetry` property on the `Mesh`
datablock and simultaneously removes the `radial_symm` property in
Sculpt, Vertex Paint, and Weight Paint.
This allows users to have these symmetry values defined on a per-object
basis instead of needing to reconfigure it for each mesh.
Current values stored on the `ToolSettings` on a per-scene basis are not
copied to each mesh in a scene. This is done to avoid introducing
potentially inaccurate data to a large number of meshes at the cost of
some minor backwards incompatibility.

"Mirror" can mean:
- To symmetrize something (i.e. generate a new mirrored copy of it or
edit it in a symmetric fashion).
- To flip something (i.e. invert its values along X, Y or Z axes).
- To repeat a texture in a mirrored fashion outside its bounds.

Replace use of bpy.ops.wm.append with the Python equivalent.
This avoids a separate append call for every group.
Also refactor lookups so node-group names only need to be declared once,
then used to populate a named-tuple.
The default nodes were still present in the node tree when Setup
Tracking Scene operator was called.
The issue was that the operator assumed the default tree always has the
same number and types of nodes, which wasn't true anymore after the
default node tree was changed in df6e65dd93
This PR keeps the changes to a minimum by updating the assumption
about the default node tree.
