During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.
This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.
This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.

Avoid computationally expensive copying operations
when only some settings have been modified.
This is done by adding support for updating parameters
without tagging for copy-on-write.
Currently only mesh data blocks are supported,
other data-blocks can be added individually.
This prepares for changing values such as edit-mesh auto-smooth angle
in edit-mode without duplicating all mesh-data.
The benefit will only be seen when the user interface no longer tags
all ID's for copy on write updates.
ID_RECALC_GEOMETRY_ALL_MODES has been added to support situations
where non edit-mode geometry is modified in edit-mode.
While this isn't something user are likely to do,
Python scripts may change the underlying mesh.

Recursive resync means also resyncing overrides that are linked from
other library files into current working file.
Note that this allows to get 'working' files even when their
dependencies are out of sync. However, since linked data is never
written/saved, this has to be re-done every time the working file is
loaded, until said dependencies are updated properly.
NOTE: This is still missing the 'report' side of things, which is part
of a larger task to enhance reports regarding both linking, and
liboverrides (see T88393).
----------
Technical notes:
Implementing this proved to be slightly more challenging than expected,
mainly because one of the key aspects of the feature was never done in
Blender before: manipulating, re-creating linked data.
This ended up moving the whole resync code to use temp IDs out of bmain,
which is better in the long run anyway (and more aligned with what we
generally want to do when manipulating temp ID data). It should also
give a marginal improvement in performances for regular resync.
This commit also had to carefully 'sort' libraries by level of indirect
usage, as we want to resync first the libraries that are the least directly
used, i.e. libraries that are most used by other libraries.

Resolve ownership ambiguity with shared physics pointers.
Previously, LIB_ID_CREATE_NO_MAIN allowed pointer sharing with
the source ID so physics caches can be shared between original and
evaluated data: (Object.soft.shared & Object.rigidbody_object.shared).
This only worked properly for LIB_TAG_COPIED_ON_WRITE ID's,
as LIB_TAG_NO_MAIN can be used in situations where the original ID's
lifetime limited by it's original data.
This commit adds `LIB_ID_COPY_SET_COPIED_ON_WRITE` so ID's only share
memory with original data for ID's evaluated in the depsgraph.
For all other uses, a full copy of physics data is made.

This fixes T87666 and T83252.
The boolean modifier and geometry nodes can depend on the geometry
of an entire collection. Before, the modifiers had to manually create relations
to all the objects in the collection. This worked for the most part, but was
cumbersome and did not solve all issues. For example, the modifiers were not
properly updated when objects were added/removed from the referenced collection.
This commit introduces the concept of "collection geometry" in the depsgraph.
The geometry of a collection depends on the transforms and geometry of all
the objects in it. The boolean modifier and geometry nodes can now just depend
on the collection geometry instead of creating all the dependencies themselves.

This is a fairly low-level ID type, so it needs to be higher in the

We can fairly easily detect some resync-needed cases when applying the
overrides operations on a Pointer RNA property.
This should cover all cases where an existing override's ID pointer is
changed in its linked data.
We still have to add code to detect when a not-yet-overridden linked ID
needs to become overridden (because its relations to other data-blocks
changed in a way that requires it).

This adds support for creating a `BlendFile` (internally called `Main`),
which is limited to a context.
Temporary data can now be created which can then use
`.libraries.load()` the same as with `bpy.data`.
To prevent errors caused by mixing the temporary ID's with data in
`bpy.data` they are tagged as temporary so they can't be assigned
to properties, however they can be passed as arguments to functions.

The `MAX_LIBARRAY` define was an annoying doublon to the `INDEX_ID_MAX` enum value
now defined in `DNA_ID.h`, and it is no more useful.
And comments were somewhat outdated. Also added an explanation about
chosen order for the `INDEX_ID_<IDTYPE>` order.

This potentially could fix some missed cases in dependency tagging (when
dealing with overrides hierarchies), since relying on tag in ID itself
is not a good idea to check whether an ID has been propcessed or not
(exterior code may have forced that tag on some IDs e.g., which would
prevent them from ever being processed properly).
|
|
This avoids adding DNA_ID.h into other headers, recently changed in
cfa48c84d06ca8197f86b6d3ceef8a2c7c311a82
Note that other enums could be moved too, this is a smaller change
to avoid indirectly including DNA_ID.h in many places.

Building IDs which are not covered by copy-on-write process was not
implemented, which was causing parameters block not present, and, hence
causing crashes in areas which expected parameters to present.
First part of this change is related on making it so Copy-on-Write is
optional for ID nodes in the dependency graph.
Second part is related on using a generic builder for all ID types
which were not covered by Copy-on-Write before.
The final part is related on making it so build_id() is properly
handling ParticleSettings and Grease Pencil Data. Before they were not
covered there at all, and they need special handling because they do
have own build functions.
Not sure it worth trying to split those parts, as they are related to
each other and are not really possible to be tested standalone. Open
for a second opinion though.
Possible nut-tightening is to re-organize build_id() function so
that every branch does return and have an assert at the end, so that
missing ID type in the switch statement is easier to spot even when
using compilers which do not report missing switch cases.
As for question "why not use default" the answer is: to make it more
explicit and clear what is a decision when adding new ID types. We do
not want to quietly fall-back to a non-copy-on-write case for a newly
added ID types.

Revert "Fix T83411: Crash when using a workspace/layout data path in a driver"
The fix for the crash exposed design violation in the viewport shading updates,
which is for some reason relying on dependency graph tag of interface data.
The viewport module did not respond to the issue in 2 weeks, and the architect
considered missing update for multiple users a more serious issue than a crash
in a very specific case.
This reverts commit 0f95f51361d73fbd8ba8d80b3b65da930dcf3b20.

First step towards a better handling of relationships between IDs in
override context, especially when a resync is needed.
First, introduce a new flag to override operations,
`IDOVERRIDE_LIBRARY_FLAG_IDPOINTER_MATCH_REFERENCE`, for ID pointers.
It keeps track of whether an RNA ID pointer has been kept to its
'natural overriden ID' (in override hierarchy context), or has actually
been re-assigned to some other data-block.
Second, refactor how we deal with relationships between IDs in override
hierarchy code, especially in resync case. This will fixe several cases
listed in T83811, especially the case where an ID pointer to an existing
override needs to be updated to a new one due to a matching change in
linked data.

Those (aka root node trees and master collections) share same 'traits'
as the shapekeys: RNA cannot assign them, so we need to handle them as
sub-data of their owner IDs.
Not sure how much this will help in improving support of overrides for
scenes and nodetrees, but this is a mandatory step towards that goal for
sure.

Document some of the less obvious implications for
re-using Python instances.

It's useful to easily see which data-blocks are assets and which not. So just
like we usually show the library linking/override icons, we show the asset icon
there (these are mutually exclusive data-block states).
Uses the `'MAT_SPHERE_SKY` icon, which wasn't used before (except by an
add-on!) and is sorta fitting, but not quite. We should either change this one
or add an own asset icon. Meanwhile this isn't too bad :)
Also adds an internal macro to check if a data-block is an asset, consistent to
how we do it for libraries and library overrides.

* Support defining (not necessarily rendering) icons in threads. Needed so the
File Browser can expose file previews with an icon-id to scripts.
** For that, ported `icons.c` to C++, to be able to use scope based mutex locks
(cleaner & safer code). Had to do some cleanups and minor refactoring for
that.
* Added support for ImBuf icons, as a decent way for icons to hold the file
preview buffers.
* Tag previews as "unfinished" while they render in a thread, for the File
Browser to dynamically load previews as they get finished.
* Better handle cases where threaded preview generation is requested, but the
ID type doesn't support it (fallback to single threaded). This is for general
sanity of the code (as in, safety and cleanness)
* Enabled asset notifier for custom preview loading operator, was just disabled
because `NC_ASSET` wasn't defined in master yet.

Asset metadata is what turns a regular data-block into an asset. It is a small
data-structure, but a key part of the technical design of the asset system.
The design foresees that asset data-blocks store an `ID.asset_data` pointer of
type `AssetMetaData`. This data **must not** have dependencies on other
data-blocks or data-block data, it must be an independent unit. That way we can
read asset-metadata from .blends without reading anything else from the file.
The Asset Browser will use this metadata (together with the data-block name,
preview and file path) to represent assets in the file list.
Includes:
* New `ID.asset_data` for asset metadata.
* Asset tags, description and custom properties.
* BKE code to manage asset meta-data and asset tags.
* Code to read asset data from files, without reading IDs.
* RNA for asset metadata (including tags)

Note that the place where this is called has been moved again, after all

The design for how we approach the "Everything Nodes" project
has changed. We will focus on a different part of the project initially.
While future me will likely refer back to some of the code I remove here,
there is no point in keeping this code around in master currently.
It would just confuse other developers working on the project.
This does not remove the simulation modifier and data block. Those are
just cleaned up, so that the boilerplate code can be reused in the future.
