Remove the redundant option to disable selection in order to simplify
the tools and UI, both conceptually and internally.
It was possible to disable curves selection completely by clicking on
the active selection domain. However, that was redundant compared to
just selecting everything by pressing "A". The remaining potential use
could have been saving a selection for later, but that can be done with
more complete attribute editing tools in the future.
When drawing strokes in Grease Pencil, it was always a bit hard
to predict how thick the strokes would be, because there was
no visual reference of the thickness in the cursor.
This patch adds that visual reference. It shows the brush size
as a circle in the draw cursor.
Showing the brush size can be toggled in the Cursor menu
of the Grease Pencil draw tool.
Request in RCS with 26 upvotes for this option:

On the technical side: the brush size is calculated
in 3D space and takes zoom level into account, as well as
object/layer transfrom, layer thickness change (gpl->line_change)
and thickness scale (gpd->pixfactor).

Until now the owner spaces in the object constraint properties used the
same descriptions as the target spaces, unlike bone constraints.
For instance, if you chose World Space as owner space, you'd get the
description: "The transformation of the target is evaluated relative to
the world coordinate system".
Reuse the existing descriptions from the bone constraints instead, so
now you get: "The constraint is applied relative to the world coordinate
system".

(MacOS) only: In the System tab of the user preferences the user has the
ability to select a GPU backend that Blender will use. After changing
the GPU backend setting, the user has to restart Blender before the
setting is used.
It was added to start collecting feedback on the Metal backend without
using the command lines.
By default Blender will select OpenGL as backend. When Metal is selected
(via `--gpu-backend metal` or via user preferences) OpenGL will be used as
fallback when the platform isn't capable of running Metal.

Such IDs are tagged with the new `LIB_TAG_RUNTIME`. They are essentially
like any other regular ID, except that they do not get written in .blend
files. They also do not make their linked data usages directly linked.
They do be written in undo steps however.
This tag should be ignored in any non-Main IDs (e.g. evaluated data,
`NO_MAIN`, etc.).
This commit also adds a new RNA ID property, `is_runtime`. This is not a
direct mapping to the DNA tag, as a non-main ID will also return True,
and the property is only editable for Main IDs.
Some basic testing for expected behavior of that new tag was also added
to `blendfile_io` py unittest.

Attributes are unifying around a name-based API, and we would like to
be able to move away from CustomData in the future. This patch moves
the identification of active and fallback (render) color attributes
to strings on the mesh from flags on CustomDataLayer. This also
removes some ugliness used to retrieve these attributes and maintain
the active status.
The design is described more here: T98366
The patch keeps forward compatibility working until 4.0 with
the same method as the mesh struct of array refactors (T95965).
The strings are allowed to not correspond to an attribute, to allow
setting the active/default attribute independently of actually filling
its data. When applying a modifier, if the strings don't match an
attribute, they will be removed.
The realize instances / join node and join operator take the names from
the first / active input mesh. While other heuristics may be helpful
(and could be a future improvement), just using the first is simple
and predictable.

This adds a new mirror image extension type for shaders and

See D16432 for a more detailed explanation of `wrap_mirror`.
This also adds a new sampler flag `GPU_SAMPLER_MIRROR_REPEAT`.
It acts as a modifier to `GPU_SAMPLER_REPEAT`, so any `REPEAT`

The `render_color_index` skips attributes with different types
and domains in order to give the proper order for the UI list.
That is a different than an index in the group of all attributes.
The most solid solution I could think of is exposing the name of
the default color attribute. It's "solid" because we always address
attributes by name internally. Doing something different is bound
to create problems. It's also aligned with the design in T98366 and
D15169.
Another option would be to change the way the "attribute index"
is incremented in Cycles. That would be a valid solution, but would
be more complex and annoying.
For consistency, I also exposed the name of the active color attribute
the same way, though it isn't necessary to fix this particular bug.
The properties aren't editable, that can come in 3.5 as part of D15169.

This allows choosing the 2d vector type in the Store Named Attribute
node. Similar to byte-colors, there is not a special socket type for this
(currently). In geometry nodes itself, vectors are all still 3d.
Recently a new geometry node for splitting edges was added in D16399.
However, there was already a similar implementation in mesh.cc that was
mainly used to fake auto smooth support in Cycles by splitting sharp
edges and edges around sharp faces.
While there are still possibilities for optimization in the new code,
the implementation is safer and simpler, multi-threaded, and aligns
better with development plans for caching topology on Mesh and other
recent developments with attributes.
This patch removes the old code and moves the node implementation to
the geometry module so it can be used in editors and RNA. The "free
loop normals" argument is deprecated now, since it was only an internal
optimization exposed for Cycles.
The new mesh `editors` function creates an `IndexMask` of edges to
split by reusing some of the code from the corner normal calculation.
This change will help to simplify the changes in D16530 and T102858.

The Blur Attribute node mixes values of neighboring elements in meshes and curves.
Currently it supports points, edges and faces on meshes and points on curves.
In theory, support for face corners could be added, but useful semantics are not
obvious yet.
The node calculates a weighted average of each element with its neighbors (based
on curve/mesh topology). The weight of the element itself is always 1, and the weight
of the neighbor elements is controlled by the weight input socket. In the future,
more options for how different elements are weight can be added (e.g. smoothing
groups and selection).
The node can perform multiple blurring iterations to achieve a blurrier result.
Generally, it is better to do multiple iterations in one node instead of using
multiple blur nodes because it has better performance in the current implementation.
We use the term "Blur" (instead of "Smooth") because smoothing is generally more
related to removing roughness from surfaces. When viewing the result of the
Blur Attribute node in the viewport, it looks like an image is blurred. While the
node can also be used to smooth surfaces, other/better algorithms exists for that
purpose (which e.g. don't reduce the volume of the mesh to zero with too many
iterations).

- Remove RNA property `Object.pose_library`
- Add comment to clarify that the call `BLO_read_id_address(reader,

Note that this functionality has been documented as deprecated since
Blender 3.2.

Name filtering in UI Lists works when:
- [one] the items to be filtered have a name property
-- see how `uilist_filter_items_default` gets the `namebuf`
- [two] custom python filter functions (`filter_items`) implement it
themselves
-- if you use `filter_items` and dont do name filtering there, the default
name filtering wont be used
So, two problems with rB8b7cd1ed2a17:
- [1] items to be listed changed from `texture_paint_images` to
`texture_paint_slots`
-- the former has name_property defined, the later lacks this
- [2] the new `ColorAttributesListBase` defined a `filter_items` function,
but did not implement name filtering
And the problem with rB4669178fc378:
- it added `filter_items` functions, but did not implement name filtering.

**Empty Slot Fix**
Currently the boolean modifier transfers the default material from
meshes with no materials and empty material slots to the faces on the
base mesh. I added this in a2d59b2dac9e for the sake of consistency,
but the behavior is actually not useful at all. The default empty
material isn't chosen by users, it just signifies "nothing," so when
it replaces a material chosen by users, it feels like a bug.
This commit corrects that behavior by only transferring materials from
non-empty material slots. The implementation is now consistent between
exact mode of the boolean modifier and the geometry node.
**Index-Based Option**
"Index-based" is the new default material method for the boolean
modifier, to access the old behavior from before the breaking commit.
a2d59b2dac9e actually broke some Boolean workflows fundamentally, since
it was important to set up matching slot indices on each operand. That
isn't the cleanest workflow, and it breaks when materials change
procedurally, but historically that hasn't been a problem. The
"transfer" behavior transfers all materials except for empty slots,
but the fundamental problem is that there isn't a good way to specify
the result materials besides using the slot indices.
Even then, the transfer option is a bit more intuitive and useful for
some simpler situations, and it allows accessing the behavior that has
been in 3.2 and 3.3 for a long time, so it's also left in as an option.
The geometry node doesn't get this new option, in the hope that we'll
find a better solution in the future.

The issue is caused by the combination of the following factors:
- There is a driver from custom property to the subdivision surface
modifier.
- Active material index tags the ID for the copy-on-write update.
Dependency graph currently does not fully distinguish between
copy-on-write tag and properties-update tag, so the copy-on-write tag
makes the dependency graph believe that it is property which actually
affects evaluation has been changed.
The simple solution is to treat the active material slot index as an
interface data which does not need to trigger copy-on-write tag.
The possible downside of this solution is that if someone has a driver
from this property the driver will stop working. Whether there is such
a real-life setup or not is not clear. Is not something advisable to do
anyway.
Possible alternative would be to introduce more granularity into the
way how property tagging is done. This is something that would be nice
to implement eventually, but it is a much bigger refactor.
