Overrides that are not created as part of an override hierarchy should
not be handled through (auto)resync at all. users are responsible to
hanlde those updates if they need it.
This is achieved by flagging overrides created outside of a hierarchical
process accordingly, and skipping them during resync process.
This case wasn't handled in rBf5ce243a56a22d718 correctly.
Now `object_get_evaluated_geometry_set` just returns a geometry
set that contains the collection instance for collection instance objects.
Since 2.8, background images are tied to cameras (in 2.79 these were
tied to a View3D I think).
Code in `BKE_library_id_can_use_idtype` wasnt taking this relation
between `Camera` and `Image` into account, thus leading to ID deletion/
unlinking not working properly -- in particular `libblock_remap_data`
not doing its thing (and leaving the camera as a user of the image),
then things went downhill from there...
Now make the "Camera-can-use-an-Image" relation clear in
`BKE_library_id_can_use_idtype`.

This flag is only used a few small cases, so instead
of setting the flag for every node only set the
required flag for the nodes that require it.
Mostly the flag is used to set `ntype.flag = NODE_PREVIEW`
For nodes that should have previews by default which
is only some compositor nodes and some texture nodes.
The frame node also sets the `NODE_BACKGROUND` flag.
All other nodes were setting a flag of 0 which has no purpose.

This implements the design detailed in T92696 to support virtual
filenames for UDIM textures. Currently, the following 2 substitution
tokens are supported:
| Token | Meaning |
| ----- | ---- |
| <UDIM> | 1001 + u-tile + v-tile * 10 |
| <UVTILE> | Equivalent to u<u-tile + 1>_v<v-tile + 1> |
Example for u-tile of 3 and v-tile of 1:
filename.<UDIM>_ver0023.png --> filename.1014_ver0023.png
filename.<UVTILE>_ver0023.png --> filename.u4_v2_ver0023.png
For image loading, the existing workflow is unchanged. A user can select
one or more image files, belonging to one or more UDIM tile sets, and
have Blender load them all as it does today. Now the <UVTILE> format is
"guessed" just as the <UDIM> format was guessed before.
If guessing fails, the user can simply go into the Image Editor and type
the proper substitution in the filename. Once typing is complete,
Blender will reload the files and correctly fill the tiles. This
workflow is new as attempting to fix the guessing in current versions
did not really work, and the user was often stuck with a confusing
situation.
For image saving, the existing workflow is changed slightly. Currently,
when saving, a user has to be sure to type the filename of the first
tile (e.g. filename.1001.png) to save the entire UDIM set. The number
could differ if they start at a different tile etc. This is confusing.
Now, the user should type a filename containing the appropriate
substitution token. By default Blender will fill in a default name using
the <UDIM> token but the user is free to save out images using <UVTILE>
if they wish.

In the past that worked because the `GPUMaterial` referenced the
`ImageUser` from the image node. However, that design was incompatible
with the recent node tree update refactor (rB7e712b2d6a0d257d272e).
Also, in general it is a bad idea to have references between data that is
owned by two different data blocks.
This incompatibility was resolved by copying the image user from the node
to the `GPUMaterial` (rB28df0107d4a8). Unfortunately, eevee depended
on this reference, because the image user on the node was update when the
frame changed. Because the image user was copied, the image user in the
`GPUMaterial` did not receive the frame update anymore.
This frame update is added back by this commit. The main change is that
the image user iterator now also iterates over image users in `GPUMaterial`s
on material and world data blocks. An issue is that these materials don't
exist on the original data blocks and that caused the check in
`build_animation_images` in the depsgraph to give the wrong answer.
Therefore the check is extended.
Right now the check is not optimal, because it results in more depsgraph
nodes than are necessary. This can be improved when it becomes cheaper
to check if a node tree contains any references to a video texture.
The node tree update refactor mentioned before makes it much easier
to construct this kind of run-time data from the bottom up, instead of
scanning the entire node tree recursively every time some information
is needed.
This just skips the entire algorithm when there are cycles.
In the future, cycles could be handled more gracefully in the
algorithm, but for now that's not worth it and is not necessary
to fix the bug.
This is analagous to 6a71b2af66 which did the same
thing for mesh data. Two differences are that here the coordinates
are simply `float3`, and we account for the radius if it's available.
Here I observed a similar performance increase, from 50ms
average to 10ms average, with 16 million points, a 5x speedup.
The calculation is about 1.4 times faster when no radius is used, down
to 7.3ms average. Before, the calculation was only 1.2 times faster.
This was caused by a mistake in eb0eb54d96, which removed
the clearing of the curve edit mode pointers that are set when creating
the temporary data for the conversion. If they are not cleared, the
generic ID free function will also free the edit mode data, which is
wrong when the source curve is in edit mode.
This just moves the relations update to a lower level function that is used
by other functions. Eventually, the special case for this node should be
generalized.
Ever since the instance domain was added, this was exposed, it just
didn't do anything. This patch implements the instances domain in the
delete and separate geometry nodes, where it acts on the top-level
instances.
We act on a mutable instances input, with the idea that eventually
copy on write attribute layers will make this less expensive. It also
allows us to keep the instance references in place and to do less
work in some situations.

This function node creates a running total of a given Vector, Float, or
Int field.
Inputs:
- Value: The field to be accumulated
- Group Index: The values of this input are used to aggregate the input
into separate 'bins', creating multiple accumulations.
Outputs:
- Leading and Trailing: Returns the running totals starting
at either the first value of each accumulations or 0 respectively.
- Total: Returns the total accumulation at all positions of the field.
There's currently plenty of duplicate work happening when multiple outputs
are used that could be optimized by a future refactor to field inputs.

The calculation to find the factor between two evaluated points assumed
that the points were not at the same location. This assumption is some-
what reasonable, since we might expect `lower_bound` to skip those
point anyway. However, the report found a case where the first two
evaluated points were coincident, and there is no strong reason not
to make this safe, so add a check for 0 length before the division.
If the override system creates an override record for the cache
name (no idea why though), it trashes the disk cache on file load.
The reason is that it tries to rename cache files in update handler
when assigning the name, and BLI_rename deletes the target file even
if both names are the same.
This is a safe fix that simply aborts the pointless rename attempt.

This evaluator is used in order to evaluate subdivision at render time, allowing for
faster renders of meshes with a subdivision surface modifier placed at the last
position in the modifier list.
When evaluating the subsurf modifier, we detect whether we can delegate evaluation
to the draw code. If so, the subdivision is first evaluated on the GPU using our own
custom evaluator (only the coarse data needs to be initially sent to the GPU), then,
buffers for the final `MeshBufferCache` are filled on the GPU using a set of
compute shaders. However, some buffers are still filled on the CPU side, if doing so
on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose
logic is hardly GPU compatible).
This is done at the mesh buffer extraction level so that the result can be readily used
in the various OpenGL engines, without having to write custom geometry or tesselation
shaders.
We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in
order to control the data layout, and interpolation. For example, we store vertex colors
as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float
types.
In order to still access the modified geometry on the CPU side, for use in modifiers
or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`.
Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will
create such a wrapper if possible. If the final subdivision surface is not needed on
the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used.
Enabling or disabling GPU subdivision can be done through the user preferences (under
Viewport -> Subdivision).

initializing the common masks in customdata.c (they were switched

The `BKE_animdata_driver_path_hack()` function has had almost no effect
since rB51b796ff1528, and basically boils down to:
```
return base_path ? base_path : RNA_path_from_ID_to_property(ptr, prop);
```
Since `base_path` was `NULL` in the majority of cases, it's just been
replaced by a direct call to `RNA_path_from_ID_to_property()`. The

rBbd3bd776c893 broke compilation here due to missing type declaration
for basic types as the source file is not including this header. In any
case, it is the responsibility of header files to include headers for
types used by value in function parameters or struct definitions.
It's better to calculate the size of a spline before creating it, and this
should simplify refactoring to a data structure that stores all point
attribute contiguously (see T94193). The mesh to curve conversion is
simplified slightly now, it creates the curve output after gathering all
of the result vertex indices. This should be more efficient too, since
it only grows an index vector for each spline, not a whole spline.
I don't think this has been visible, since I only ran into it after
changing other code that affected this. However, some attributes
can keep a reference to the source component to use when tagging
caches dirty (like the position attribute tagging the normals dirty).
Here, the component was created inside a function, then the attributes
were used afterwards.
Also add some comments warning about this in the header file.

This replaces the single-threaded calculation of mesh min and max
positions with a `parallel_reduce` loop. Since the bounding box
of a mesh is retrieved quite often (at the end of each evaluation,
currently 2(?!) times when leaving edit mode, etc.), this makes for a
quite noticeable speedup actually.

I added some methods to `float3` so they would be inlined, but
they're also a nice addition, since they're used often anyway.

Fix is similar to how CollectionObject with NULL object pointers are handled.
Using one of the 'free' pad bytes in Object_Runtime struct instead of a
gset (or other external way to detect object duplicates), as this is
several times faster.
NOTE: This makes remapping slightly slower again (adds 10 extra seconds

General improvements of remapping time complexity, especially when
remapping a lot of IDs at once, is a separate topic currently
investigated in D13615.
This commit fixes the crash itself, however this can still lead to a
same collection 'owning' the same object several time.
Issue here was a bad assumption in layer resync code, that would lead to
removing valid objects from the viewlayer's `object_bases_hash` in

of bases duplicate.
When copying a full node tree, we can avoid an O(n^2) loop finding a

That is a reasonable assumption, since unique names are verified

This commit makes freeing a node tree about 25 to 30 times faster.
Freeing a node tree happens whenever it is edited. Freeing a node
tree with about 4000 nodes went from 30-50ms to about 2 ms.
This was so slow before because for every node that was freed
when freeing the node tree, `node_free_node` looped over all
other nodes to detach frames, and then looped over all links to
remove any links connected to the node. That was all pointless
work because everything else is about to be freed anyway.
Instead, move that "detaching" behavior to the dedicated function
for removing a single node, and to the "local" version of the free
function to be safe, since I know less about what that version expects.
