This is to be used when calling code already knows whether the 'made
local' linked ID should be copied, or can directly be converted to a
local one.
Currently unused , this is preparation for rewrite of append code.
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.

We need to separate the flag telling duplicate code to not handle
remapping to new IDs etc., from the one telling the code that we are
currently duplicating a 'root' ID (i.e. not a dependency of another
duplicated ID).
This whole duplicate code/logic is still fairly unsatisfying, think it
will need further refactor, or maybe even re-design, at some point...
This was not really useful, and added estra useless steps in case and ID
should not actually be written.
Further more, it prevented clearing the usercount on write, which can be
cause a false positive 'chanhged' detection in undo/redo case.
This patch exposes the Cycles Alembic Procedural through the MeshSequenceCache
modifier in order to use and test it from Blender.
To enable it, one has to switch the render feature set to experimental and
activate the Procedural in the modifier. An Alembic Procedural is then
created for each CacheFile from Blender set to use the Procedural, and each
Blender object having a MeshSequenceCache modifier is added to list of objects
of the right procedural.
The procedural's parameters derive from the CacheFile's properties which are
already exposed in the UI through the modifier, although more Cycles specific
options might be added in the future.
As there is currently no cache controls and since we load all the data at the
beginning of the render session, the procedural is only available during
viewport renders at the moment. When an Alembic procedural is rendered, data
from the archive are not read on the Blender side.
If a Cycles render is not active and the CacheFile is set to use the Cycles Procedural,
bounding boxes are used to display the objects in the scene as a signal that the
objects are not processed by Blender anymore. This is standard in other DCCs.
However this does not reduce the memory usage from Blender as the Alembic data
was already loaded either during an import or during a .blend file read.
This is mostly a hack to test the Cycles Alembic procedural until we have a
better Blender side mechanism for letting renderers load their own geometry,
which will be based on import and export settings on Collections (T68933).

The immediate reason for this is that we want to be able to initialize them
to different defaults for light objects, which is hard with Python properties.
But in general it is useful to be able to share these with other renderers.
As a side effect, Eevee now supports a per-object holdout instead of only
per-collection.

Extend the 'reading error' container to produce the generic short
message in the popup directly visible by the user, and move all detailed
info the `INFO` reports that only show up in the console and Info
editor.
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

Using the "Camera Fit Frame to Selected" operator didn't work for Grease Pencil
objects. The same issue caused grease pencil preview thumbnails to be useless
(e.g. when using "Mark Asset" on a Grease Pencil object).
Reason was that there was no logic to handle grease pencil data and its strokes
for the object display-point iterators used for the "Frame Selected" logic.

Many ui features for geometry nodes need access to information generated
during evaluation:
* Node warnings.
* Attribute search.
* Viewer node.
* Socket inspection (not in master yet).
The way we logged the required information before had some disadvantages:
* Viewer node used a completely separate system from node warnings and
attribute search.
* Most of the context of logged information is lost when e.g. the same node
group is used multiple times.
* A global lock was needed every time something is logged.
This new implementation solves these problems:
* All four mentioned ui features use the same underlying logging system.
* All context information for logged values is kept intact.
* Every thread has its own local logger. The logged informatiton is combined
in the end.

This would prevent loading a parent that would only be referenced by
children during a linking operation.
Looks like this missing bit of code has been there since the stone ages,
it is fairly baffling to find that such critical low-levels mistakes can
survive decades in a codebase...
Note that such fully-indirectly linked parent object is not instantiated
in scene currently, this is fairly bad I think, but kind of a different
issue.
Generally the evaluated mesh should not be changed, since that is the
job of the modifier stack. Current code is far from const correct in
that regard. This commit uses a const variable for the reult of
`BKE_object_get_evaluated_mesh` in some cases. The most common
remaining case is retrieving a BVH tree from the mesh.
This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,
etc.

Sharing data between duplicated IDs should be restricted to depsgraph
(CoW) cases, not all NO_MAIN ones...
While this was probably not an issue currently, we aim at using more and
more out-of-main IDs for temp data processing.
NOTE: Somewhat related to T88555, and similar issue as the one fixed in
rBdfb963c70df5.
Previously, the "follow path constraint" and "follow parented curve"
were clamped. This restriction was lifted in rBcf2baa585cc8
Add back an option to get the old behavior in the "Path animation" settings.

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.

Rename BKE_object_runtime_free -> BKE_object_runtime_free_data,
since the runtime pointer is part of the object, only the data is freed.
Leave the data cleared to avoid accidental use,
this is in keeping with other `*_free_data()` functions.
While fa7ddd0f43 fixed the reported issue,
the possibility of reusing runtime data during curve-to-mesh conversion
remained. Instead of treating the bounding-box as a special case,
clear all run-time data for temporary objects.

`ob->runtime.geometry_set_eval` can contain instances as well.
This only affected instances generated by geometry nodes.
We should probably have a separate function that tells us if an object
has instances or not..
This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

Previously, the spreadsheet editor could only show data of the original
and of the final evaluated object. Now it is possible to show the data
at some intermediate stages too.
For that the mode has to be set to "Node" in the spreadsheet editor.
Furthermore, the preview of a specific node has to be activated by
clicking the new icon in the header of geometry nodes.
The exact ui of this feature might be refined in upcoming commits.
It is already very useful for debugging node groups in it's current
state though.

The issue was that where_on_path uses a resampled curve to get the data
from the curve. This leads to disconnects between the curve the user
sees and the evaluated location data.
To fix this we simply use the actual curve data the user can see.
The older code needed a cleanup either way as there were hacks in other
parts of the code trying to work around some brokenness. This is now
fixed and we no longer need to clamp the evaluation range to 0-1 or make
helper functions to make it do what we actually want.

Initially this is a typo when solving merge conflict back in 2017
in commit rBf4140f2c8138.
The code was so for 3 years, so it is safer to assume that this is
the new expected design. The affected codepath only comes from the
BKE_object_modifier_update_subframe() which is discouraged from use
and have other issues.
Eventually those offending codepaths will be removed completely.
The grade-schema for now is more localized: remove ID_RECALC_ALL
which seems to be misused and is causing issues like the ones which
are described and discussed in T81340.
On user level there should be no measurable changes. In fact, no
functional changes at all are expected to happen.
