This adds support for attaching gizmos for input values. The goal is to make it
easier for users to set input values intuitively in the 3D viewport.
We went through multiple different possible designs until we settled on the one
implemented here. We picked it for it's flexibility and ease of use when using
geometry node assets. The core principle in the design is that **gizmos are
attached to existing input values instead of being the input value themselves**.
This actually fits the existing concept of gizmos in Blender well, but may be a
bit unintutitive in a node setup at first. The attachment is done using links in
the node editor.
The most basic usage of the node is to link a Value node to the new Linear Gizmo
node. This attaches the gizmo to the input value and allows you to change it
from the 3D view. The attachment is indicated by the gizmo icon in the sockets
which are controlled by a gizmo as well as the back-link (notice the double
link) when the gizmo is active.
The core principle makes it straight forward to control the same node setup from
the 3D view with gizmos, or by manually changing input values, or by driving the
input values procedurally.
If the input value is controlled indirectly by other inputs, it's often possible
to **automatically propagate** the gizmo to the actual input.
Backpropagation does not work for all nodes, although more nodes can be
supported over time.
This patch adds the first three gizmo nodes which cover common use cases:
* **Linear Gizmo**: Creates a gizmo that controls a float or integer value using
a linear movement of e.g. an arrow in the 3D viewport.
* **Dial Gizmo**: Creates a circular gizmo in the 3D viewport that can be
rotated to change the attached angle input.
* **Transform Gizmo**: Creates a simple gizmo for location, rotation and scale.
In the future, more built-in gizmos and potentially the ability for custom
gizmos could be added.
All gizmo nodes have a **Transform** geometry output. Using it is optional but
it is recommended when the gizmo is used to control inputs that affect a
geometry. When it is used, Blender will automatically transform the gizmos
together with the geometry that they control. To achieve this, the output should
be merged with the generated geometry using the *Join Geometry* node. The data
contained in *Transform* output is not visible geometry, but just internal
information that helps Blender to give a better user experience when using
gizmos.
The gizmo nodes have a multi-input socket. This allows **controlling multiple
values** with the same gizmo.
Only a small set of **gizmo shapes** is supported initially. It might be
extended in the future but one goal is to give the gizmos used by different node
group assets a familiar look and feel. A similar constraint exists for
**colors**. Currently, one can choose from a fixed set of colors which can be
modified in the theme settings.
The set of **visible gizmos** is determined by a multiple factors because it's
not really feasible to show all possible gizmos at all times. To see any of the
geometry nodes gizmos, the "Active Modifier" option has to be enabled in the
"Viewport Gizmos" popover. Then all gizmos are drawn for which at least one of
the following is true:
* The gizmo controls an input of the active modifier of the active object.
* The gizmo controls a value in a selected node in an open node editor.
* The gizmo controls a pinned value in an open node editor. Pinning works by
clicking the gizmo icon next to the value.

This adds a new `name` member to the `GeometrySet` class. This name can be set
with the new `Set Geometry Name` node. Currently, the name is only used in the
spreadsheet when displaying instances.
The main purpose of this name is to help debugging in instance trees. However, in the
future it may also be used when exporting instance trees or when creating separate
objects from them.
Note, the name is not expected to be unique, it is fully in user control.
Naming geometries is necessary to make the spreadsheet more useful for instances,
because currently the user has no information for which geometry is used by each instance.
We also want to use this name to improve the integration with grease pencil where
sometimes layers become instances with the same name.

When the repository is owned by another Blender session,
support removing the file-system lock.
This is accessible from a menu in the repository popover.
This is needed if Blender exits unexpectedly while a repository
is being modified (typically install/upgrade).
Addresses #122135.
While this wasn't likely to cause any problems in practice,
using the sub-command "build --split-platform" with a platform
containing any characters that need escaping would have produced a TOML
with invalid syntax.
Add a utility function that's guaranteed to create a valid TOML string.
Uses the OpenXR extension XR_FB_PASSTHROUGH_EXTENSION_NAME,
compatible mainly with the Meta Quest family of devices.
Currently, passthrough support over OpenXR is disabled by default
in the Quest Link app, and must be manually enabled in its settings
to use this feature.
The performance of the passthrough render varies with the quality
of the connection between the headset and the PC. For better results,
connecting the headset directly through USB to the PC, or at least
connecting the PC to the local network over ethernet, is recommended.
Thanks a lot to [KISKA](https://kiska.com/)
for their support in the development of this feature.

- Sort add menu alphabetically
- Use forward declaration for GeometrySet again
- Use `this->` to access class methods
- Use `MEM_cnew`
- Fix typo
- Pass Span by value
- Pass MutableSpan instead of Vector &
- Remove unnecessary whitespace
- Use `BLI_SCOPED_DEFER` for freeing non-RAII objects
- Use `is_empty()` instead of `size() == 0`
- Use `GeometrySet::from_mesh` ability to handle null argument
Add a node similar to the STL import node (d1455c4138) that
imports OBJ files, including both meshes and curves. The output consists
of a geometry instance for each mesh/curve in the file.
There are a few improvements to address in the future: Currently the node
has no inputs besides the file path. Options may be exposed in the future.
Materials are also not imported yet, because creating material data-blocks
during evaluation may not be trivial.

This is the main merge commit of the brush assets project. The previous
commits did some preparing changes, more tweaks are in the following commits.
Also, a lot of the more general work was already merged into the main branch
over the last two years.
With the new design, quite some things can be removed/replaced:
- There's a unified "Brush" tool now, brush based tools and all special
handling is removed.
- Old tool and brush icons are unsed now, and their initialization code
removed here. That means they draw as blank now, and the icon files can be
removed in a follow up.
- Creation of default brushes is unnecessary since brushes are now bundled in
the Essentials asset library. Icons/previews are handled as standard asset
previews.
- Grease pencil eraser options are replaced by a general default eraser brush
that can be set by the user.
More changes are planned still, see task list issue below.

Asset system files (using the `.asset.blend` extension) are special and cannot
be edited like normal files. Opening them showes warnings about this. So better
not "encourage" editing these files that much.
Note that this check will result in false positives, since users may create
files with this extension. Asset system files have an extra flag stored
identifying them. Accessing that from the asset representation is a bit more
involved, probably requires changes in the asset indexer. For now keeping it
simple, the false positives are not a big deal for this convenience operator.

The function `rna_def_attributes_common` assumed that the owner of the
attributes is an `ID`. This PR refactors the code to partially remove this
assumption.
The `rna_def_attributes_common` function now takes an argument
`AttributeOwnerType type` that defines what `AttributeGroup` should be used.
This is in preperation for #116043 where we want to use
`rna_def_attributes_common` for grease pencil drawings, which are not IDs.
In addition to the refactor explained above, this also changes the API
slightly:
Previously, the `AttributeGroup` defiend `active_color`,
`active_color_index`, `active_color_name`, `default_color_name`, and
`render_color_index` for all IDs. These properties could only be used by
meshes. So this PR seperates the `AttributeGroup` type into one type
per attribute owner: `AttributeGroupMesh`, `AttributeGroupPointCloud`,
`AttributeGroupCurves`, and `AttributeGroupGreasePencil`.
As such the properties mentioned above are now only usable by meshes.
Note that this technically breaks the API and will have to be noted in the
release notes.

A few files included in reports contained normals that were not normalized.
In order to contain consistent normals around smooth corner fans, sharp
edges are added when neighboring corner normals aren't close enough.
Non-unit-vector normals also triggered this check.
Blender used to do this implicitly when the derived `MeshLoop.normal`
value was set. That API has been changed already, and it's clearer if the
addon provides normalized normals, so this PR adds a normalization
step to the FBX importer.

The functionality of the Bone Selection Sets add-on is now integrated
into Blender itself. Rigify has been updated to no longer check for the
add-on, but just assume that the functionality is available.
The keymap is still the same, and so are all the class names. This
ensures that there are no conflicts when people still have the old
add-on enabled somehow. And there is versioning code to remove the
'add-on enabled' state so that Blender won't complain it cannot find it
any more.
Compared to the add-on, the following changes are made:
- The 'bone' icon has been removed from the list of available selection
sets. It was the same for each entry anyway, and thus didn't provide
any information.
- The code has been split up into multiple files, with the UI elements
in `scripts/startup/bl_ui/properties_data_armature.py` and the
operators in `scripts/startup/bl_operators/bone_selection_sets.py`.
- Helper functions and classes are prefixed with `_` to indicate that
they are not part of any public API.
- The `Operator` helper subclasses have been transformed to mix-in
classes. This way the only subclasses of `Operator` are the actual
operators.
- Comments & descriptions have been updated for clarity & consistency.

The `[build.generated]` section now includes a filtered list of wheels
to simplify checking existing wheels on the server.
Also disallow quotes & control characters in wheel paths because they
already shouldn't be used and doing so would cause escaping issues in
the generated TOML.
Implements #124242.
Exceptions need be caught and forwarded so they show it in Blender's
interface. While most common errors where accounted for, various IO
errors & malformed JSON/TOML could cause internal operations to fail

Adds snapping in the VSE preview area.
Source points are the four corners and origins of all selected, visible

Rename 'Binding' to 'Slot'. The old term was causing all kind of
confusion, and 'slot' was considered to be a better term for the
intended functionality.
This commit breaks existing blend files that were using the new layered
Action for their animation. The animation data will be lost due to the
rename, as there is no versioning code or DNA renaming logic. At this
time the new system is still marked as experimental, so shouldn't be
used for anything serious anyway.
