Goals of this refactor:
* Simplify creating virtual arrays.
* Simplify passing virtual arrays around.
* Simplify converting between typed and generic virtual arrays.
* Reduce memory allocations.
As a quick reminder, a virtual arrays is a data structure that behaves like an
array (i.e. it can be accessed using an index). However, it may not actually
be stored as array internally. The two most important implementations
of virtual arrays are those that correspond to an actual plain array and those
that have the same value for every index. However, many more
implementations exist for various reasons (interfacing with legacy attributes,
unified iterator over all points in multiple splines, ...).
With this refactor the core types (`VArray`, `GVArray`, `VMutableArray` and
`GVMutableArray`) can be used like "normal values". They typically live
on the stack. Before, they were usually inside a `std::unique_ptr`. This makes
passing them around much easier. Creation of new virtual arrays is also
much simpler now due to some constructors. Memory allocations are
reduced by making use of small object optimization inside the core types.
Previously, `VArray` was a class with virtual methods that had to be overridden
to change the behavior of a the virtual array. Now,`VArray` has a fixed size
and has no virtual methods. Instead it contains a `VArrayImpl` that is
similar to the old `VArray`. `VArrayImpl` should rarely ever be used directly,
unless a new virtual array implementation is added.
To support the small object optimization for many `VArrayImpl` classes,
a new `blender::Any` type is added. It is similar to `std::any` with two
additional features. It has an adjustable inline buffer size and alignment.
The inline buffer size of `std::any` can't be relied on and is usually too
small for our use case here. Furthermore, `blender::Any` can store
additional user-defined type information without increasing the
stack size.

When proxy size lower than 100% is used, clip strips are rendered with
incorrect image size.
This is because if proxies aren't enabled in movieclip, it automatically
falls back on rendering original media. Sequencer doesn't have knowledge
about this and since 9c99292a16 it assumes that image is proxy,
because it explicitly requested this size.

When cut an stroke using the option Flat Caps, the falt was not done if the cut was done in the middle of the stroke.
Now the flat is applied to the segments created and also some cleanup of the code done.
Cause of this issue is that Custom Node Sockets info type was
initialized as SOCK_FLOAT when registering. Areas within the core that
would ignore custom socket types by checking its type would use the
socket as being a float type.
When custom node sockets have a property called default_value blender
tries to store it as an internal default value what failed in debug
builds.
This patch will set the socket type to SOCK_CUSTOM when registering a
custom socket type and allow, but skip storage of custom default values.
In this case the default values should already be stored as custom

Blender 3.0 will only support single-frame Actions in the pose library.
The goal of this patch is to lay the groundwork for making it possible
for the Asset Browser to reject/hide "animation snippet" Action assets.
Determining whether an Action has one or more frames (i.e. whether it
has a single pose or animation) requires inspecting the Action itself,
and thus loading the data-block itself. This would make it impossible to
quickly determine from the asset browser.
To solve this, the Action is inspected before saving, and a
`"is_single_frame"` boolean (well, 0/1 integer) IDProperty is added.

During animation playback, data-blocks are reallocated, so storing
pointers to the resulting data is not okay. Instead, the data should
be retrieved from the context. This works when the applied search
item is the "dummy" item added for non-matches. However, it still
crashes for every other item, because the memory is owned by the
modifier value log, which has been freed by the time the exec function
runs.
The next part of the solution is to allow uiSearchItems
to own memory for the search items.
The point domain attributes (stored on splines) are sorted so they

Usually modifiers use `CustomData_copy` to create a compatible new

attributes when they are no longer used.
This lead to attributes being copied incorrectly.

For now I just removed the optimization.

Currently the curve to mesh node relies on the order of attributes being

new attributes without any regard to the order. To fix this, I added a
"reorder" step after all the merged attributes have been created, the
types have been joined, etc. It should be possible to change this code
so that the attributes are added with the right order in the first
place, but I would like to do that after refactoring spline attribute

Previously, `ImageTile->ok` and `ImageUser->ok` were used to indicate
whether an image failed to load. There were three possible values
which (probably) had the following meanings:
* `0`: There was an error while loading the image. Don't try to load again.
* `1`: Default value. Try to load the image.
* `2`: The image was loaded successfully.
This image-wide flag did not make sense unfortunately, because loading
may work for some frames of an image sequence but not for others.
Remember than an image data block can also contain a movie.
The purpose of the `->ok` flag was to serve as an optimization to avoid
trying to load a file over and over again when there is an error (e.g. the
file does not exist or is invalid). To get the optimization back, the patch
is changing `MovieCache` so that it can also cache failed load attempts.
As a consequence, `ibuf` is allowed to be `NULL` in a few more places.
I added the appropriate null checks.
This also solves issues when image sequences are used with the

rB43bc494892c3 switched `BKE_libblock_relink_to_newid` to use new ID

However, that new code does protect by default against remapping an

not a behavior that generic BKE code can handle (due to required editing
data for most obdata types when in edit mode).
So specific code that does create new IDs and need remapping in Edit
mode has to pass specific exception flags to remaping code.
This commit adds those remapping flags to `BKE_libblock_relink_to_newid`
and add said exception flag to the remapping call from
`ED_object_add_duplicate` when the object is in edit mode.
In theory we should never allow remapping of Objects' obdata ID pointer
when the object is in Edit mode. But there are some cases were this is
needed, so adding yet another exception option to remapping flags.

Remapping code could call collection resync code while processing
remapping, which is a good way to crash by accessing no-more-valid

This was probably not an issue in practice in current code, since this

* Make panels look like panels again (like in v2.3!)
* Make use of roundness in more widgets
* Since nodes are no longer hard-coded to be transparent, tweak opacity and saturation
* Tweak colors for the new dot grid
This update does not include:
* Meshes in edit mode to match greenish object-data color. This needs tweaks in the code to improve contrast.
* A copy of the Blender 2.8x legacy theme. This could be added to the community themes (shouldn't cost much maintenance, I hope)

This adds generic attribute rendering support for meshes for Eevee and
Workbench. Each attribute is stored inside of the `MeshBufferList` as a
separate VBO, with a maximum of `GPU_MAX_ATTR` VBOs for consistency with
the GPU shader compilation code.
Since `DRW_MeshCDMask` is not general enough, attribute requests are
stored in new `DRW_AttributeRequest` structures inside of a convenient
`DRW_MeshAttributes` structure. The latter is used in a similar manner
as `DRW_MeshCDMask`, with the `MeshBatchCache` keeping track of needed,
used, and used-over-time attributes. Again, `GPU_MAX_ATTR` is used in
`DRW_MeshAttributes` to prevent too many attributes being used.
To ensure thread-safety when updating the used attributes list, a mutex
is added to the Mesh runtime. This mutex will also be used in the future
for other things when other part of the rendre pre-processing are multi-threaded.
`GPU_BATCH_VBO_MAX_LEN` was increased to 16 in order to accommodate for
this design.
Since `CD_PROP_COLOR` are a valid attribute type, sculpt vertex colors
are now handled using this system to avoid to complicate things. In the
future regular vertex colors will also use this. From this change, bit
operations for DRW_MeshCDMask are now using uint32_t (to match the
representation now used by the compiler).

- otherwise: on-disk catalog replaces in-memory one
- Already-known catalog that does not exist in CDF:
- local unsaved changes: catalog is kept around
- otherwise: catalog is deleted.
Because this saving-is-also-loading behaviour, the "has unsaved changes"
flags are all stored in the undo buffer; undoing after saving will not
change the CDF, but at least it'll undo the loading from disk, and it'll
re-mark any changes as "not saved".

These nodes just output a single value of their respective types,
making it possible to control multiple inputs with the same value.

Camera, lattice and speaker object types were missing there own proper
`USER_DUP_` flags, leading to not properly handling duplication of their
object data.
NOTE: We could probably simply opions here, by using categories (like
'GEOMETRY', 'SHADING', etc.) instead of exact object types. But this is
beyond bugfix scope.
This commit makes the bounding box node work on each unique geometry
(including instances) individually instead of making one large bounding
box for everything. This makes the node much faster, and is often the
desired result anyway. For the old behavior, a realize instances node
can be used in front of this node (versioning adds it automatically).
The min and max outputs now only output the values from the realized
geometry.

When renaming an asset catalog, also update its simple name.
Catalogs will most likely be created from within Blender, so via the
catalog tree in the asset browser. Here catalogs are always named
"Catalog" until the user renames them, which was reflected in all simple
names being "Catalog".
When there are multiple catalogs with the same path (so different UUIDs
all mapped to the same catalog path), treat the first-loaded one as the
main catalog for that path, and the rest as aliases.
This ensures that the UUID of a catalog (as chosen in the tree UI and thus
interacted with by users) is stable, regardless of whether by some coincidence
later another catalog with the same UUID is created.
Rename `AssetCatalogPathCmp` to `AssetCatalogLessThan`:
- it compares more than paths (so no more `Path` in the name), and
- performs a less-than operation (so no more `Cmp` in the name).
Also restructure its code to make an extra upcoming comparison easier to
add.
No functional changes.
This is mainly for doversion code, when it needs to create new IDs those
should be considered as part of the same library as the current Main's
one.
No practical changes are expected here, this is more of a general
consistency fix, and a pre-requisite for {T92333}.
Since the introduction in rBfc5bf09fd88c, `BKE_pose_minmax` was not
taking these custom transforms into account (making "View Selected"
ignoring these as well and focusing on the bone instead).
Now consider these transforms in `BKE_pose_minmax`.

When appending an asset from the asset browser, its asset data needs to
be cleared.
However, linking an asset (or regular append from the file browser)
should not clear such data. In linking case, it would be there again
after a blend file reload anyway.
So this commit introduces a new `BLO_LIBLINK_APPEND_ASSET_DATA_CLEAR`
option.
NOTE: in case the appended ID needs to be copied from its linked data
(instead of making the later directly local), asset data is lost anyway
since it is never copied with the ID currently.
Ref. {T91749} and D11768.
In order to address feedback that the "Stable ID" was not easy enough
to use, remove the "Stable ID" output from the distribution node and
the input from the instance on points node. Instead, the nodes write
or read a builtin named attribute called `id`. In the future we may
add more attributes like `edge_id` and `face_id`.
The downside is that more behavior is invisible, which is les
expected now that most attributes are passed around with node links.
This behavior will have to be explained in the manual.
The random value node's "ID" input that had an implicit index input
is converted to a special implicit input that uses the `id` attribute
if possible, but otherwise defaults to the index. There is no way to
tell in the UI which it uses, except by knowing that rule and checking
in the spreadsheet for the id attribute.
Because it isn't always possible to create stable randomness, this
attribute does not always exist, and it will be possible to remove it
when we have the attribute remove node back, to improve performance.

This commit adds an updated version of the curve to points that
supports fields. Only the position and radius are transferred
by default now, which should improve performance. The other outputs
like tangent and rotation are outputted with anonymous attributes.
I took the opportunity to change a few other small things:
- Name geometry sockets "Curve" and "Points" like other nodes.
- Remove the radius multiple of 0.1, which was confusing.

Yet another try at that hairy issue... See comment in commit for
details, essentially this extend the workaround introduced in Objects'
`lib_override_apply_post` callback to try to also properly 're-use'
`OUTDATED` and `BAKED` flags from old source liboverride into new
destination one.
When the input vector gets close to -Y, y and theta becomes totally
unreliable. It is thus necessary to compute the result in a different
way based on x and z. The code already had a special case, but:
- The threshold for using the special case was way too low.
- The special case was not precise enough to extend the threshold.
- The special case math had a sign error, resulting in a jump.
This adds tests for the computation precision and fixes the issues
by adjusting the threshold, and replacing the special case with one
based on a quadratic Taylor expansion of sqrt instead of linear.
Replacing the special case fixes the bug and results in a compatibility
break, requiring versioning for the roll of affected bones.

Separate the huge test into huge logical parts and add more cases
to check. Also add a utility to check that the matrix is orthogonal,
with arbitrary epsilon values and calculations in double.
A couple of tests deliberately fail, to be fixed in following commits.

This commit adds a node that can be used to find and replace strings
inside of the input string. One initial use case is to have an easier

No longer save asset catalogs on blendfile save. Instead:
- extend the confirmation prompt for unsaved changes to show unsaved
catalogs.
- In the confirmation prompt, make catalog saving explicit & optional,
just like we do it for external images. {F10881736}
- In the Asset Browser catalog tree, show an operator icon to save the
catalogs to disk. It's grayed out if there are no changes to save, or
if the .blend wasn't saved yet (required to know where to save the
catalog definitions to). {F10881743}
Much of the work was done by @Severin and reviewed by me, then we
swapped roles.

Allow creating a new asset catalog in a yet-to-be-saved blend file. The
problem was caused by `AssetLibrary` not having an `AssetCatalogService`
right after creation; only after loading data from disk was this
instance created. It's now always there.
This patch includes an updated version of the raycast node that uses
fields instead of attributes for inputs instead of outputs. This makes
the node's UI much clearer. It should be faster too, since the
evaluation system for fields provides multi-threading.
The source position replaces the input geometry (since this node is
evaluated in the context of a geometry like the other field nodes).
Thanks to @guitargeek for an initial version of this patch.

Make `AssetLibraryService::get_asset_library_on_disk(path)` insensitive
to trailing slashes; i.e. `get_asset_library_on_disk("/path")` and
`get_asset_library_on_disk("/path/¨)` will now return the same
`AssetLibrary*`.
`BKE_callback_remove` now checks whether the callback actually is known,
before trying to remove it.
`BKE_blender_atexit()` runs after `BKE_callback_global_finalize()`. When
an at-exit callback tried to unregister its BKE callbacks, these would
already be unregistered, causing a crash of Blender when exiting,
This commit removes the implicit conversion from points to a mesh
that used to happen before the next modifier. It also removes the
implicit realizing of instances that happened before another modifier.
Now we have specific nodes for both of these operations, the
implicit conversions make less sense, and implicit instance
realizing has already been removed in other nodes.
This adds another geometry nodes modifier before modifiers that would
have realized instances implicitly before. Currently adding another
data-block during versioning after linking means that an assert needs
to be changed. That should be made unnecessary by T92333.

Some compositing applications do not support spaces and dots in layer names, and change
these to other symbols on import. This causes various compatibility issues, including
with Cryptomatte metadata. While technically those could be considered bugs in the
Cryptomatte implementation of other software, where they are not properly accounting for
that layer renaming, it's not ideal.
The OpenEXR channel naming convention is "layer.pass.channel". We get away with dots in
the layer name since we parse this from right to left, but it's a weak assumption.
Now we don't forbid using spaces or dots, and existing files are unchanged. But at
least by default names will be compatible, and hopefully other software catches up in
time to support more flexible layer names.
Ref T68924
OpenEXR uses "." to separate layers/passes/channels, so using AOV.001 is
a problem. Other applications will not be able to parse it correctly.
Default to AOV_001 instead, and don't allow using dots in AOV names.
