This patch replaces the existing transfer attribute node with three
nodes, "Sample Nearest Surface", "Sample Index", and "Sample Nearest".
This follows the design in T100010, allowing for new nodes like UV
sampling in the future. There is versioning so the new nodes replace
the old ones and are relinked as necessary.
The "Sample Nearest Surface" node is meant for the more complex
sampling algorithms that only work on meshes and interpolate
values inside of faces.
The new "Sample Index" just retrieves attributes from a geometry at
specific indices. It doesn't have implicit behavior like the old
transfer mode, which should make it more predictable. In order to not
change the behavior from existing files, the node has a has a "Clamp",
which is off by default for consistency with the "Field at Index" node.
The "Sample Nearest" node returns the index of the nearest element
on a geometry. It can be combined with the "Sample Index" node for
the same functionality as the old transfer node. This node can support
curves in the future.
Backwards compatibility is handled by versioning, but old versions can
not understand these nodes. The warning from 680fa8a523e0 should make
this explicit in 3.3 and earlier.

Using the attribute name semantics from T97452, this patch moves the
selection status of mesh elements from the `SELECT` of vertices, and
edges, and the `ME_FACE_SEL` of faces to generic boolean attribute
Storing this data as generic attributes can significantly simplify and
improve code, as described in T95965.
The attributes are called `.select_vert`, `.select_edge`, and
`.select_poly`. The `.` prefix means they are "UI attributes",so they
still contain original data edited by users, but they aren't meant to
be accessed procedurally by the user in arbitrary situations. They are
also be hidden in the spreadsheet and the attribute list.
Until 4.0, the attributes are still written to and read from the mesh
in the old way, so neither forward nor backward compatibility are
affected. This means memory requirements will be increased by one byte
per element when selection is used. When the flags are removed
completely, requirements will decrease.
Further notes:
* The `MVert` flag is empty at runtime now, so it can be ignored.
* `BMesh` is unchanged, otherwise the change would be much larger.
* Many tests have slightly different results, since the selection
attribute uses more generic propagation. Previously you couldn't
really rely on edit mode selections being propagated procedurally.
Now it mostly works as expected.

This is very similar to D14077. There are two differences though.
First is that vertex creases are already stored in a separate layer,
and second is that we can now completely remove use of `Mesh.cd_flag`,
since that information is now inherent to whether the layers exist.
There are two functional differences here:
* Operators are used to add and remove layers instead of a property.
* The "crease" attribute can be created and removed by geometry nodes.
The second change should make various geometry nodes slightly faster,
since the "crease" attribute was always processed before. Creases are
now interpolated generically in the CustomData API too, which should
help maintain the values across edits better.
Meshes get an `edge_creases` RNA property like the existing vertex
property, to provide more efficient access to the data in Cycles.
One test failure is expected, where different rounding between float
the old char storage means that 5 additional points are scattered in
a geometry nodes test.

This functionality was present until Blender 2.80. Basically it adds back the
"+" and "-" buttons in the file browser when it stores an output filepath.
This is useful for someone rendering multiple versions of an animation (or a
composition) to compare.
At the moment this is used for the render output, and the File Output node in
the compositor.

Add the Redo panel to the dopesheet & NLA editors. This also implicitly
adds it to the timeline editor, since it's a kind of action editor
internally.
This feature is needed for changing advanced properties of animation
operators, such as select grouped (see D14811). But it can also be
useful for existing operators, like precise keyframe position tweaking.
Changes are basically the same as in D6286 (which added the redo panel
for Graph Editor).
Some operators have internal properties that should be hidden. A full
list can be found in T98195. These will be fixed in a follow-up patch.

Since D15885, most (all?) python based importers are failing with an
error like RuntimeError: Error: Object 'Cube' can't be selected
because it is not in View Layer, whenever they try to mark
just-created objects selected via obj.select_set(True). Happens at
least in FBX and (legacy) OBJ importers -- effectively they end up
creating just the first imported object before failing with this
exception.

This commit adds a node to distribute points inside of volume grids.
The "Random" mode usese OpenVDB's "point scatter" implementation, and
there is also a "Grid" mode for uniform distributions. Both methods
operate on all of the float grids in the volume, using every voxel with
a value higher than the threshold. The random method is not stable as
the input volume deforms.

This value was used to close gaps, but now with the new system is not needed.
Internally, still we need to keep a small leak size, but after doing a lot of test a
value of 3 is perfect, so it's harcoded.

|
|
|
The new names are:
* Radius
* Extend
The mode Radius + Extend has been removed.
Also, some code cleanup and format.
|
|
The motivation for this change: while working on an animation recently, I found that there are some gaps that won't close easily via stroke extension or leak size checking. In D14698, I attempted to address this by changing the algorithm of the raster-space flood fill. This patch attempts to address the same issue in vector space by adding two new cases where stroke extensions are added, as suggested by @frogstomp:
# **Points of high curvature:** when the curvature at a point is high enough that it's hard to visually distinguish between it and an endpoint, add a stroke extension out along the normal (pointing in the opposite direction of the stroke's acceleration.) This addresses cases where technically the endpoint points up, but there's a sharp corner right below it that should extend to connect.
# **Stroke endpoints within a radius**: when two endpoints are close together, regardless of the angle they make, connect them if they are within a radius. This addresses cases like where the two endpoints have effectively parallel tangents, so extensions won't close the gap.

Whether faces are hidden and face sets are orthogonal concepts, but
currently sculpt mode stores them together in the face set array.
This means that if anything is hidden, there must be face sets,
and if there are face sets, we have to keep track of what is hidden.
In other words, it adds a bunch of redundant work and state tracking.
On the user level it's nice that face sets and hiding are consistent,
but we don't need to store them together to accomplish that.
This commit uses the `".hide_poly"` attribute from rB2480b55f216c to
read and change hiding in sculpt mode. Face sets don't need to be
negative anymore, and a bunch of "face set <-> hide status" conversion
can be removed. Plus some other benefits:
- We don't need to allocate either array quite as much.
- The hide status can be read from 1/4 the memory as face sets.
- Updates when entering or exiting sculpt mode can be removed.
- More opportunities for early-outs when nothing is hidden.
- Separating concerns makes sculpt code more obvious.
- It will be easier to convert face sets into a generic int attribute.

When a change happens which invalidates view layers the syncing will be postponed until the first usage.
This will improve importing or adding many objects in a single operation/script.
`BKE_view_layer_need_resync_tag` is used to tag the view layer to be out of sync. Before accessing
`BKE_view_layer_active_base_get`, `BKE_view_layer_active_object_get`, `BKE_view_layer_active_collection`
or `BKE_view_layer_object_bases` the caller should call `BKE_view_layer_synced_ensure`.
Having two functions ensures that partial syncing could be added as smaller patches in the future. Tagging a
view layer out of sync could be replaced with a partial sync. Eventually the number of full resyncs could be
reduced. After all tagging has been replaced with partial syncs the ensure_sync could be phased out.
This patch has been added to discuss the details and consequences of the current approach. For clarity
the call to BKE_view_layer_ensure_sync is placed close to the getters.
In the future this could be placed in more strategical places to reduce the number of calls or improve
performance. Finding those strategical places isn't that clear. When multiple operations are grouped
in a single script you might want to always check for resync.
Some areas found that can be improved. This list isn't complete.
These areas aren't addressed by this patch as these changes would be hard to detect to the reviewer.
The idea is to add changes to these areas as a separate patch. It might be that the initial commit would reduce
performance compared to master, but will be fixed by the additional patches.
**Object duplication**
During object duplication the syncing is temporarily disabled. With this patch this isn't useful as when disabled
the view_layer is accessed to locate bases. This can be improved by first locating the source bases, then duplicate
and sync and locate the new bases. Will be solved in a separate patch for clarity reasons ({D15886}).
**Object add**
`BKE_object_add` not only adds a new object, but also selects and activates the new base. This requires the
view_layer to be resynced. Some callers reverse the selection and activation (See `get_new_constraint_target`).
We should make the selection and activation optional. This would make it possible to add multiple objects
without having to resync per object.
**Postpone Activate Base**
Setting the basact is done in many locations. They follow a rule as after an action find the base and set
the basact. Finding the base could require a resync. The idea is to store in the view_layer the object which
base will be set in the basact during the next sync, reducing the times resyncing needs to happen.

This change adds cryptomatte render passes to EEVEE-Next. Due to the upcoming viewport
compositor we also improved cryptomatte so it will be real-time. This also allows viewing
the cryptomatte passes in the viewport directly.
{F13482749}
A surface shader would store any active cryptomatte layer to a texture. Object hash is stored
as R, Asset hash as G and Material hash as B. Hashes are only calculated when the cryptomatte
layer is active to reduce any unneeded work.
During film accumulation the hashes are separated and stored in a texture array that matches
the cryptomatte standard. For the real-time use case sorting is skipped. For final rendering
the samples are sorted and normalized.
NOTE: Eventually we should also do sample normalization in the viewport in order to extract the correct
mask when using the viewport compositor.

corresponding data layers and using their values for computations.
Avoiding that should increase performance in many operations that
would otherwise have to read, write, or propagate these values.
It also means decreased memory usage-- not just for sculpt mode
but for any mesh that was in sculpt mode. Previously the mask, face set,
and hide status layers were *always* allocated by sculpt mode.
Here are a few basic tests when masking and face sets are not used:
| Test | Before | After |
| Subsurf Modifier | 148 ms | 126 ms |
| Sculpt Overlay Extraction | 24 ms every redraw | 0 ms |
| Memory usage | 252 MB | 236 MB |
I wouldn't expect any difference when they are used though.
The code changes are mostly just making sculpt features safe for when
the layers aren't stored, and some changes to the conversion to and
from the hide layers. Use of the ".hide_poly" attribute replaces testing
whether face sets are negative in many places.

As described in T95966, the goal is to move to a "struct of arrays"
approach rather than gathering an arbitrary set of data in hard-coded
structs. This has performance benefits, but also code complexity
benefits (this patch removes plenty of code, though the boilerplate
for the new operators outweighs that here).
To mirror the internal change, the options for storing mesh bevel
weights are converted into operators that add or remove the layer,
like for some other layers.
The most complex change is to the solidify modifier, where bevel
weights had special handling. Other than that, most changes are
removing clearing of the weights, boilerplate for the add/remove
operators, and removing the manual transfer of bevel weights
in bmesh - mesh conversion.
Eventually bevel weights can become a fully generic attribute,
but for now this patch aims to avoid most functional changes.
Bevel weights are still written and read from the mesh in the old way,
so neither forward nor backward compatibility are affected. As described
in T95965, writing in the old format will be done until 4.0.

- Remove "take ownership" argument which was confusing and always true
- The argument made ownership very confusing
- Better to avoid boolean arguments that switch a function's purpose
- Remove "mask" argument which was basically wrong and not used properly
- "EVERYTHING" was used because developers are wary of removing data
- Instead use `CD_MASK_MESH` for its purpose of original mesh data
- Remove use of shallow copied temporary mesh, which is unnecessary now
- Split shape key processing into separate functions and use C++ types
- Copy fields explicitly rather than using memcpy for the whole struct
- Use higher level functions and avoid redundant code
- The whole idea is pretty simple and can be built from standard logic
