Previously, the code tried to keep node groups working even if some of
their input/output sockets had undefined type. This caused some
complexity with no benefit because not all places outside of this file
would handle the case correctly. Now node groups with undefined
interface sockets are disabled and have to be fixed manually before
they work again.
Undefined interface sockets are mostly caused by invalid Python
API usage and incomplete forward compatibility (e.g. when newer
versions introduce new socket types that the older version does
not know).

Attributes are unifying around a name-based API, and we would like to
be able to move away from CustomData in the future. This patch moves
the identification of active and fallback (render) color attributes
to strings on the mesh from flags on CustomDataLayer. This also
removes some ugliness used to retrieve these attributes and maintain
the active status.
The design is described more here: T98366
The patch keeps forward compatibility working until 4.0 with
the same method as the mesh struct of array refactors (T95965).
The strings are allowed to not correspond to an attribute, to allow
setting the active/default attribute independently of actually filling
its data. When applying a modifier, if the strings don't match an
attribute, they will be removed.
The realize instances / join node and join operator take the names from
the first / active input mesh. While other heuristics may be helpful
(and could be a future improvement), just using the first is simple
and predictable.

- Use typed enum for the wrap axis.
- Rename `bounds` to `wrap_region`.
- Take a `rcti` argument instead of an `int[4]`.
- Pair wrap & wrap_region arguments together.
This adds a new mirror image extension type for shaders and
geometry nodes (next to the existing repeat, extend and clip
options).
See D16432 for a more detailed explanation of `wrap_mirror`.
This also adds a new sampler flag `GPU_SAMPLER_MIRROR_REPEAT`.
It acts as a modifier to `GPU_SAMPLER_REPEAT`, so any `REPEAT`

This patch implements the Ghost Glare node. It is implemented using
direct convolution as opposed to a recursive one, which produces
slightly different results---more accurate ones, however, since the
ghosts are attenuated where it matters, the difference is barely
visible and is acceptable as far as I can tell.
A possible performance improvement is to implement all passes in a
single shader dispatch, where an array of all scales and color
modulators is computed recursively on the host then used in the shader
to add all ghosts, avoiding usage of global memory and unnecessary
copies. This optimization will be implemented separately.

Steps to reproduce were:
- Open a .blend file that is located inside of an asset library and
contains assets.
- Save and close the file.
- Open a new file (Ctrl+N -> General).
- Open asset browser and load the asset library from above.
- If the assets from the file above still show up, press refresh button.
- -> Assets from the file above don't appear.
Likely fixes the underlying issue for T102610. A followup will be needed
to correct the empty asset index files written because of this bug.
We're in the process of moving responsibilities from the file/asset
browser backend to the asset system. 1efc94bb2f introduces a new
representation for asset, which would own the asset metadata now instead
of the file data.
Since the file-list code still does the loading of asset libraries,
ownership of the asset metadata has to be transferred to the asset
system. However, the asset indexing still requires it to be available,
so it can update the index with latest data. So transfer the ownership,
but still keep a non-owning pointer set.

This patch adds an integer identifier to nodes that doesn't change when
the node name changes. This identifier can be used by different systems
to reference a node. This may be important to store caches and simulation
states per node, because otherwise those would always be invalidated
when a node name changes.
Additionally, this kind of identifier could make some things more efficient,
because with it an integer is enough to identify a node and one does not
have to store the node name.

**Empty Slot Fix**
Currently the boolean modifier transfers the default material from
meshes with no materials and empty material slots to the faces on the
base mesh. I added this in a2d59b2dac9e for the sake of consistency,
but the behavior is actually not useful at all. The default empty
material isn't chosen by users, it just signifies "nothing," so when
it replaces a material chosen by users, it feels like a bug.
This commit corrects that behavior by only transferring materials from
non-empty material slots. The implementation is now consistent between
exact mode of the boolean modifier and the geometry node.
**Index-Based Option**
"Index-based" is the new default material method for the boolean
modifier, to access the old behavior from before the breaking commit.
a2d59b2dac9e actually broke some Boolean workflows fundamentally, since
it was important to set up matching slot indices on each operand. That
isn't the cleanest workflow, and it breaks when materials change
procedurally, but historically that hasn't been a problem. The
"transfer" behavior transfers all materials except for empty slots,
but the fundamental problem is that there isn't a good way to specify
the result materials besides using the slot indices.
Even then, the transfer option is a bit more intuitive and useful for
some simpler situations, and it allows accessing the behavior that has
been in 3.2 and 3.3 for a long time, so it's also left in as an option.
The geometry node doesn't get this new option, in the hope that we'll
find a better solution in the future.

The copy-on-write is really an implementation detail of the
dependency graph. While there are still cases where there is
no better tag to be used, the ID_RECALC_COPY_ON_WRITE should
not be used in combination with a dedicated tag.
For example if location of object changes the proper tag is
`ID_RECALC_TRANSFORM`. Tagging with `ID_RECALC_TRANSFORM |
ID_RECALC_COPY_ON_WRITE` will seemingly work, but this is
not an intended usage.
This wasn't used for backwards compatibility, because Blender does not
read from the `nodetype` anywhere. It also wasn't used for forward
compatibility, because it was not initialized for new node groups.
This is not used for anything in practice currently. The original intention
was probably to generate different socket subtypes, but that is solved
differently now (e.g. using `NodeSocketFloatDistance`). It's possible
that an addon tried to use this but it's rather unlikely.

This avoids need to do special trickery detecting whether the principal
point is to be changed when reloading movie clip. This also allows to
transfer the optical center from high-res footage to possibly its lower
resolution proxy without manual adjustment.
On a user level the difference is that the principal point is exposed in
the normalized coordinates: frame center has coordinate of (0, 0), left
bottom corner of a frame has coordinate of (-1, -1) and the right top
corner has coordinate of (1, 1).
Another user-visible change is that there is no more operator for setting
the principal point to center: use backspace on the center sliders will
reset values to 0 which corresponds to the center.
The code implements versioning in both directions, so it should be
possible to open file in older Blender versions without loosing
configuration.
For the Python API there are two ways to access the property:
- `tracking.camera.principal_point` which is measured in the normalized
space.
- `tracking.camera.principal_point_pixels` to access the pixel-space
principal point.
Both properties are not animatable, so there will by no conflict coming.

Historically tracks and reconstruction for motion tracking camera
object were stored in the motion tracking structure. This is because
the data structures pre-dates object tracking support, and it was
never changed to preserve compatibility.
Now the compatibility code supports more tricks and allows to change
the ownership without breaking any compatibility. This is what this
change does: it moves tracks from motion tracking structure to the
motion tracking camera object, and does it in a way that no
compatibility is broken.
One of the side-effects of this change is that the active track is
now stored on motion tracking object level, which allows to change
active motion tracking object without loosing active track. Other
than that there are no expected user-level changes.
Instead of generating a dependency sorted node list whenever evaluating
texture or EEVEE/viewport shader nodes, use the existing sorted array
from the topology cache. This may be more efficient because the
algorithm isn't quadratic. It's also the second-to-last place to
use `node.runtime->level`, which can be removed soon.

As part of T95966, this patch moves loose edge information out of the
flag on each edge and into a new lazily calculated cache in mesh
runtime data. The number of loose edges is also cached, so further
processing can be skipped completely when there are no loose edges.
Previously the `ME_LOOSEEDGE` flag was updated on a "best effort"
basis. In order to be sure that it was correct, you had to be sure
to call `BKE_mesh_calc_edges_loose` first. Now the loose edge tag
is always correct. It also doesn't have to be calculated eagerly
in various places like the screw modifier where the complexity
wasn't worth the theoretical performance benefit.
The patch also adds a function to eagerly set the number of loose
edges to zero to avoid building the cache. This is used by various
primitive nodes, with the goal of improving drawing performance.
This results in a few ms shaved off extracting draw data for some
large meshes in my tests.
In the Python API, `MeshEdge.is_loose` is no longer editable.
No built-in addons set the value anyway. The upside is that
addons can be sure the data is correct based on the mesh.
**Tests**
There is one test failure in the Python OBJ exporter: `export_obj_cube`
that happens because of existing incorrect versioning. Opening the
file in master, all the edges were set to "loose", which is fixed
by this patch.

* This patch just moves runtime data to the runtime struct to cleanup

* `miniwidth` was removed completely, because it was not used anywhere.
The corresponding rna property `width_hidden` is kept to avoid

* Since rna is in C, some helper functions where added to access the
C++ runtime data from rna.
* This size of `bNode` decreases from 432 to 368 bytes.

The draw locking was implemented for project Heist and moved behind an experimental
feature after it became clear there were issues with it. Nowadays it isn't used,

been ported to the new draw manager API. {T102180}
This patch will remove the experimental feature as it isn't used, or useful.
Bounding box calculation can be a large in some situations, especially
instancing. This patch caches the min and max of the bounding box in
runtime data of meshes, point clouds, and curves, implementing part of
T96968.
Bounds are now calculated lazily-- only after they are tagged dirty.
Also, cached bounds are also shared when copying geometry data-blocks
that have equivalent data. When bounds are calculated on an evaluated
data-block, they are also accessible on the original, and the next
evaluated ID will also share them. A geometry will stop sharing bounds
as soon as its positions (or radii) are changed.
Just caching the bounds gave a 2-3x speedup with thousands of mesh
geometry instances in the viewport. Sharing the bounds can eliminate
recalculations entirely in cases like copying meshes in geometry nodes
or the selection paint brush in curves sculpt mode, which causes a
reevaluation but doesn't change the positions.
**Implementation**
The sharing is achieved with a `shared_ptr` that points to a cache mutex
(from D16419) and the cached bounds data. When geometries are copied,
the bounds are shared by default, and only "un-shared" when the bounds
are tagged dirty.
Point clouds have a new runtime struct to store this data. Functions
for tagging the data dirty are improved for added for point clouds
and improved for curves. A missing tag has also been fixed for mesh
sculpt mode.
**Future**
There are further improvements which can be worked on next
- Apply changes to volume objects and other types where it makes sense
- Continue cleanup changes described in T96968
- Apply shared cache design to more expensive data like triangulation
or normals
