501b0190d6 LibOverride: Deprecate Proxies: Add auto-conversion on file load.
This commit also add an experimental userPreferences to prevent proxies
conversions on file load, and reporting for amount of coverted proxies
(and possible issues).

Note that potentially linked proxies from other libraries are not
hamdled here (this feature seems to be broken anyway in master
currently?).

61f3d4eb7c Geometry Nodes: Initial socket visualization for fields.
This implements the update logic for the vizualization of which
sockets pass data or constants directly, and which pass functions.
The socket shapes may still have to be updated. That should be
done separately, because it might be a bit more involved, because
socket shapes are currently linked to keyframe shapes. Currently
the circle and diamond shapes are used with the following meanings:

 - Input Sockets:
    - Circle: Required to be a single value.
    - Diamond: This input supports fields.
 - Output Sockets:
    - Circle: This output is a single value.
    - Diamond: This output may be a field.

Connecting a field to a circle input socket is an error, since a
field cannot be converted to a single value. If the socket shape
is a diamond with a dot in the middle, it means it is currently
a single value, but could be a field.

In addition to socket shapes, the intention is to draw node links
differently based on the field status. However, the exact method for
conveying that isn't decided yet.

9b12b23d0b Assets: add Asset Catalog system
Catalogs work like directories on disk (without hard-/symlinks), in that
an asset is only contained in one catalog.

See T90066 for design considerations.

#### Known Limitations

Only a single catalog definition file (CDF), is supported, at
`${ASSET_LIBRARY_ROOT}/blender_assets.cats.txt`. In the future this is
to be expanded to support arbitrary CDFs (like one per blend file, one
per subdirectory, etc.).

The current implementation is based on the asset browser, which in
practice means that the asset browser owns the `AssetCatalogService`
instance for the selected asset library. In the future these instances
will be accessible via a less UI-bound asset system.

The UI is still very rudimentary, only showing the catalog ID for the
currently selected asset. Most notably, the loaded catalogs are not
shown yet. The UI is being implemented and will be merged soon.

#### Catalog Identifiers

Catalogs are internally identified by UUID. In older designs this was a
human-readable name, which has the problem that it has to be kept in
sync with its semantics (so when renaming a catalog from X to Y, the
UUID can be kept the same).

Since UUIDs don't communicate any human-readable information, the
mapping from catalog UUID to its path (stored in the Catalog Definition
File, CDF) is critical for understanding which asset is stored in which
human-readable catalog. To make this less critical, and to allow manual
data reconstruction after a CDF is lost/corrupted, each catalog also has
a "simple name" that's stored along with the UUID. This is also stored
on each asset, next to the catalog UUID.

#### Writing to Disk

Before saving asset catalogs to disk, the to-be-overwritten file gets
inspected. Any new catalogs that are found thre are loaded to memory
before writing the catalogs back to disk:

- Changed catalog path: in-memory data wins
- Catalogs deleted on disk: they are recreated based on in-memory data
- Catalogs deleted in memory: deleted on disk as well
- New catalogs on disk: are loaded and thus survive the overwriting

#### Tree Design

This implements the initial tree structure to load catalogs into. See
T90608, and the basic design in T90066.

3042994c91 Link/Append: Refactor flags.
Flags controlling link/append code are split between two enums, one in
`DNA_space_types.h` and one in `BLO_readfile.h`.

This commit:
 - Moves flags exclusively used in WM and BLO code to `eBLOLibLinkFlags`
   in `BLO_readfile.h`. Flags in `eFileSel_Params_Flag` from
   `DNA_space_types.h` are now only the ones effectively used by the
   file browser editor code too.
 - Fixes some internal utils in `readfile.c` still taking `short` flag
   parameter instead of proper `int` one.

NOTE: there are a few other flags that could probably be moved to
`eBLOLibLinkFlags` (at the very least `FILE_LINK`, probably also
`FILE_AUTOSELECT` and `FILE_ACTIVE_COLLECTION`), since those are not
effectively used by the file browser, and control linking/appending
behavior, not filebrowser behavior.

However for now think it's safer to not touch that.

794c2828af Initial implementation of local ID re-use when appending.
This commit adds to ID struct a new optional 'weak reference' to a
linked ID (in the form of a blend file library path and full ID name).

This can then be used on next append to try to find a matching local ID
instead of re-making the linked data local again.

Ref. T90545

NOTE: ID re-use will be disabled for regular append for the time being
(3.0 release), and only used for assets. Therefore, this commit should
not change anything user-wise.

0d350e0193 Geometry Nodes: Curve Fillet Node
This node can be used to fillet splines at control points to
create a circular arc.
The implementation roughly follows T89227's design.

The node works in two main modes: Bezier and Poly
* Bezier: Creates a circular arc at vertices by changing
handle lengths (applicable only for Bezier splines).
* Poly: Creates a circular arc by creating vertices (as
many as defined by the Count fields input) along
the arc (applicable for all spline types).

In both modes, the radius of the created arc is defined
by the Radius fields input.
The Limit Radius attribute can be enabled to prevent
overlapping when the defined radius exceeds the maximum
possible radius for a given point.

997b5fe45d VSE strip thumbnails
Draw thumbnails as strip overlay. This works for movie and image strips.
To draw thumbnails, this overlay has to be enabled and strips must be
tall enough.

The thumbnails are loaded from source file using separate thread and
stored in cache.

Drawing code uses only images stored in cache, and if any is missing,
background rendering job is started. If job can not render thumbnail,
to prevent endless loop of creating job for missing image it sets
`SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag.

To prevent visual glitches during timeline panning and zooming, `View2D`
flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code
will look for set of evenly distributed thumbnails that should be
guaranteed to exist and also set of previously displayed thumbnails.
Due to volatile nature of cache these thumbnails can be missing anyway,
in which case no new thumbnails will be drawn for particular strip.

Cache capacity is limited to 5000 thumbnails and performs cleanup of
non visible images when limit is reached.

c9d9bfa84a Keymap: preference for fallback-tool with RMB select
Expose a key-map preference "Fallback Tool (RMB)",
disabled by default.

The right mouse button uses the fallback tool
(currently visible selection tool in the toolbar),
instead of always tweaking.

When any selection tool is active, right mouse always tweaks.

To enable fallback selection on RMB, set the "Right Mouse Select Action"
to "Selection Tool".

Internal changes:

- Add fall-back key-maps, separate key-maps needed for when the tool is
  run as a fall-back. This is needed so RMB-select can support fall-back
  tools, so left-mouse can be used when it's the active tool and RMB
  can be used as a fall-back action when another tool is active.
- Add options field to tools so tools without gizmos can enable the
  full-back tool keymap.
- Support multiple key-maps for keymap handlers.
- Fall-back keymaps now co-exist with the tool-keymaps.
  So both keymaps may be active at once - using different mouse buttons.
  When gizmos are in use, a highlighted gizmo prioritizes the
  tool-keymap over the fall-back keymap.

17021adcea Geometry Nodes: Curve Sample Node
This node allows sampling positions, tangents, and normals at any
arbitrary point along a curve. The curve can include multiple splines,
all are taken into account. The node does not yet support transferring
generic attributes like radius, because some more general tooling will
make that much more feasible and useful in different scenarios.

This is a field node, so it is evaluated in the context of a data-flow
node like "Set Position". One nice thing about that is it can easily
be used to move an entire geometry like the follow path constraint.

The point along the curve is chosen either with a factor of the total
length of the curve, or a length into the curve, the same choice used
in the curve trim node.

b9febb54a4 Geometry Nodes: Support modifier on curve objects
With this commit, curve objects support the geometry nodes modifier.

Curves objects now evaluate to `CurveEval` unless there was a previous
implicit conversion (tessellating modifiers, mesh modifiers, or the
settings in the curve "Geometry" panel). In the new code, curves are
only considered to be the wire edges-- any generated surface is a mesh
instead, stored in the evaluated geometry set.

The consolidation of concepts mentioned above allows remove a lot of
code that had to do with maintaining the `DispList` type temporarily
for modifiers and rendering. Instead, render engines see a separate
object for the mesh from the mesh geometry component, and when the
curve object evaluates to a curve, the `CurveEval` is always used for
drawing wire edges.

However, currently the `DispList` type is still maintained and used as
an intermediate step in implicit mesh conversion. In the future, more
uses of it could be changed to use `CurveEval` and `Mesh` instead.

This is mostly not changed behavior, it is just a formalization of
existing logic after recent fixes for 2.8 versions last year and two
years ago. Also, in the future more functionality can be converted
to nodes, removing cases of implicit conversions. For more discussion
on that topic, see T89676.

The `use_fill_deform` option is removed. It has not worked properly
since 2.62, and the choice for filling a curve before or after
deformation will work much better and be clearer with a node system.

Applying the geometry nodes modifier to generate a curve is not
implemented with this commit, so applying the modifier won't work
at all. This is a separate technical challenge, and should be solved
in a separate step.

128eb6cbe9 Modifiers: export motion blur velocity through attribute
Previously fluid simulation and Alembic modifiers had a dedicated function
to query the velocity for motion blur. Now use a more generic system where
those modifiers output a velocity attribute.

Advantages:
* Geometry and particle nodes can output velocity through the same mechanism,
  or read the attribute coming from earlier modifiers.
* The velocity can be preserved through modifiers like subdivision surface or
  auto smooth.
* USD and Alembic previously only output velocity from fluid simulation, now
  they work with velocity from other sources too.
* Simplifies the code for renderers like Cycles and exporters like
  Alembic and USD.

This breaks compatibility:
* External renderers and exporters accessing these velocities through the
  Python API now need to use the attribute instead.
* Existing modifier node setups that create an attribute named "velocity"
  will render differently with motion blur.

bf47fb40fd Geometry Nodes: fields and anonymous attributes
This implements the initial core framework for fields and anonymous
attributes (also see T91274).

The new functionality is hidden behind the "Geometry Nodes Fields"
feature flag. When enabled in the user preferences, the following
new nodes become available: `Position`, `Index`, `Normal`,
`Set Position` and `Attribute Capture`.

Socket inspection has not been updated to work with fields yet.

Besides these changes at the user level, this patch contains the
ground work for:
* building and evaluating fields at run-time (`FN_fields.hh`) and
* creating and accessing anonymous attributes on geometry
  (`BKE_anonymous_attribute.h`).

For evaluating fields we use a new so called multi-function procedure
(`FN_multi_function_procedure.hh`). It allows composing multi-functions
in arbitrary ways and supports efficient evaluation as is required by
fields. See `FN_multi_function_procedure.hh` for more details on how
this evaluation mechanism can be used.

A new `AttributeIDRef` has been added which allows handling named
and anonymous attributes in the same way in many places.

c8f80453d5 Modifier: add support for vertex groups
Allow blending the imported cache with the modifiers stack above the
MeshCache modifier.

This is particularly useful for instance when dealing with cloth
simulations performed in another software, where some parts of the cloth
are completely pinned (non-simulated, following the armature). Indeed,
this would allow modifying the animation in some areas without having to
rebake the other parts or the cloth, resulting in a much more flexible
workflow.

2b2d427bba Fix T90825: Performance texture painting with limited scale.
Improve texture painting/uv editing performance when limited scale is active.
Cause of the slow down is that the image editor draws the image in maximum resolution,
but the 3d viewport uses the limited scale. The variation reuses the same GPU texture
and needed to be uploaded/scaled twice to the GPU.

This patch will adds texture slots that can hold the scaled down and the maximum
resolution image. This would allow better cache hits and reuse of existing caches.

Maximum resolution textures are reused for limited scale when they fit to reduce memory
and CPU footprint.

5a9a16334c Geometry Nodes: support for geometry instancing
Previously, the Point Instance node in geometry nodes could only instance
existing objects or collections. The reason was that large parts of Blender
worked under the assumption that objects are the main unit of instancing.
Now we also want to instance geometry within an object, so a slightly larger
refactor was necessary.

This should not affect files that do not use the new kind of instances.

The main change is a redefinition of what "instanced data" is. Now, an
instances is a cow-object + object-data (the geometry). This can be nicely
seen in `struct DupliObject`. This allows the same object to generate
multiple geometries of different types which can be instanced individually.

A nice side effect of this refactor is that having multiple geometry components
is not a special case in the depsgraph object iterator anymore, because those
components are integrated with the `DupliObject` system.

Unfortunately, different systems that work with instances in Blender (e.g.
render engines and exporters) often work under the assumption that objects are
the main unit of instancing. So those have to be updated as well to be able to
handle the new instances. This patch updates Cycles, EEVEE and other viewport
engines. Exporters have not been updated yet. Some minimal (not master-ready)
changes to update the obj and alembic exporters can be found in P2336 and P2335.
Different file formats may want to handle these new instances in different ways.

For users, the only thing that changed is that the Point Instance node now
has a geometry mode.

This also fixes T88454.
