Changing a node tree item property (such as the default value) was using a very
broad and generic "tag" function which invalidates the runtime items cache.
This also invalidates any python iterators due to the API using the runtime
cache. Changing node tree items in a loop will then crash.
It's not necessary to invalidate the runtime items cache when the actual item
pointers have not changed. Most RNA updates only change superficial properties,
or at most require a recursive node tree update due to change of identifiers or
types.
This PR introduces a simpler "tag" function to only tag for tree updates by not
rebuild the entire runtime items cache. It also renames existing functions and
docstrings to better explain what each of them does and should be used for.
The `NodeTreeInterfaceChangedFlag` is removed completely because it is only ever
used as a simple boolean indicator of "item changes" that require a cache
rebuild. It is replaced with an atomic bool like flags used for runtime caches.

This simplifies the bake API used by Geometry Nodes by using `SocketValueVariant`
instead of raw pointers. This is possible now, because all socket types use
`SocketValueVariant` under the hood.
Pull Request: https://projects.blender.org/blender/blender/pulls/144410
Now that every socket type uses `SocketValueVariant` since #144355, the
parameter access code can be simplified a bit.
This also adds a new `GeoNodesMultiInput<T>` type that's used to access the list
of inputs value multi-input sockets.

Parallelizes implementation for computing the NURBS basis cache.
Removing the unnecessary linear 'find span' search. Due to formulation
of the span find implementation, breakpoints are now evaluated in the
following span rather then in the previous. This does not affect the
point evaluation results, but adjusts how they are computed in the
basis cache.
On top of the threading improvement, removal of the linear search
also means the computational complexity goes from O(n^2) to O(n).
For a very large NURBS curve (250K points), performance is increased
by roughly 40 000 times, and is now interactive!
For cases with large number of small curves. Tests with 25K curves
and 10 control points per curve also indicated a slight performance
improvement, with roughly a 13% reduction in execution time.

Fixes missing isolated vertices in `mesh_apply_spatial_organization` by
ensuring non-added vertices (ones not forming a face) are appended to
new_vert_order, preserving correct vertex ordering for meshes with
disconnected geometry.

One thing to keep in mind is that while `ob->actcol` is one-based (if
materials are assigned), `active_material_index` is zero-based so we
have a couple of places to make sure whenever materials are assigned,
we should always be in the range of `1..totcol` for `ob->actcol`.
In the particular case of the report, the last remaining material slot
was removed (`ob->actcol` gets rightfully zero then), but assigning a
material from the `template_ID` then calls `BKE_object_material_assign`
with zero as the active index.
The internal `act` number was corrected [ `std::max<int>(act, 1)` ],
but did not end up in `ob->actcol`.
`BKE_object_material_resize` [which all code assigning/removing/...
materials eventually comes down to] used to do the "sanitizing" actually
(but exited early when `totcol` didn't actually change).
There were other places to, clamping to a proper upper or lower bound.
So to resolve, move the code for sanitizing into its own function and
use it after `BKE_object_material_resize` (and from a couple of places).

- Make PTCACHE_COMPRESS_ an actual enum
- Clarify that while it looks like bitmask, it really is just an enum
- Make ptcache_file_compressed_write take similar arguments as
ptcache_file_write (item count and item size)
- All callers of ptcache_file_compressed_write were doing compressed
result memory allocation in exactly the same way; just make it happen
inside the function itself. This also makes it no longer need
the callers to do "is this zstd?" check around the call.
- The lzma "props" buffer was dynamically allocated for no good reason,
just make it a simple array, and clarify the variable names.
- Remove BLI_assert_unreachable() from ptcache_file_compressed_read;
asserts are for "impossible" situations; this one just happens any
time one opens a 4.x file with caches in 5.0.

The code path isn't well defined when there aren't any faces, causing
the vert, face, and corner normal caches to call each other, potentially
trying to lock the same mutex twice.
Duplicating a strip that references an ID like the scene strip would not
duplicate the scene. This is wanted in some workflows.
To align with the rest of Blender, this changes the behavior for how
strips are duplicated:
* `Shift + D` ("duplicate"): Duplicate the strip and also duplicate the
IDs referenced by the strip. Currently this only affects `Scene`,
`MovieClip`, and `Mask` strips.
* `Alt + D` ("duplicate linked"): Duplicate the strip, but reference the
same IDs. This is the current behavior in `main`.
Part of #144063.

This is similar to #144199. It needs a few more changes because more places
handle geometries in a special way compared to data-block sockets.
It might be that there are more usages of `GeometrySet` as value for geometry
sockets instead of `SocketValueVariant`. Unfortunately, there isn't really an
automated way to find these. So far I found all the places that needed fixing
through tests.
This is the last socket type that did not use `SocketValueVariant` yet. So
afterwards, it's likely possible to simplify a bunch of code to use
`SocketValueVariant` instead of `void *`.

During a short period (Blender 500 sub 33) the legacy custom data
struct was saved in an invalid state. This adds a check to

The remapping from old to new linked IDs was done one by one, with all
the related pre/post processing. In particular for objects, this could
easily lead to quadratic cost (need to loop over all objects for each
object)...
Solved by reworking the remapping logic in relocation code to process
all linked data in a single call.
From quick tests locally, it makes relocating a library with 10k object
got from 50s to about 5s.
A 40k linked objects case goes from 'way too long to measure' to about 4
minutes.
So there is likely still some things that could be improved here
(processing time still does not seem to be O(n)), but at least it's
usable now.

The previous code to get unique instance ids did not actually ensure 100%
uniqueness. Now the code does and hence the "almost" from the name is removed.
In practice, this change likely does not have any impact because the fallback
case is very unlikely to be reached.

The fix is to detect when the compute context is recursive and to stop the
search early in that case. Currently, this does not generate a warning. There
will be a warning when trying to evaluate the recursive closure though.

Use `SocketValueVariant` for all the data-block types as well. Before it was
used for e.g. float, integer and menu sockets.
The only remaining type afterwards is the geometry socket which will be moved
separately.
Using `SocketValueVariant` for all socket types will simplify code later on and
also removes the need for dealing with raw memory in more cases.

Moves more animation theme properties shared by different editors to the new Common panel.
- Playhead (was shared by 7 editors)
- Marker Line (was shared by 5 editors)
- Marker Line Selected (was shared by 5 editors)
- Channel (was shared by 3 editors)
- Sub-channel (was shared by 3 editors)
- Channel Group (was shared by 2 editors)
- Active Channel Group (was shared by 2 editors)
In total, 27 properties are replaced with 7.
---
User Visible Changes:
- "Current Frame" is renamed to "Playhead". It was general sentiment among
Anim and UI modules to rename this everywhere after "Playhead Snapping" was
added, and this is first step towards that. Name is more recognizable and it's
clear it refers to UI element, rather than something as generic as "current frame".
- Channel, Sub-channel, Channel Group, and Active Channel Group colors in
Dope Sheet had alpha, but ones in Graph and NLA editors didn't. New common
property is used for all three of them and has alpha, meaning two editors gain
alpha as well, but they don't use alpha, still only Dope Sheet does.
- Channel and Sub-channel had different color in NLA and didn't match Dope Sheet
and Graph Editor, now since it's shared it has same color, which is a visual change
(slighlty lighter blue).

There should be minimal user-measurable changes since the old algorithm
is not the same as OpenSubdiv. For example now creases (both edge and
vertex ones) are properly supported.
This allows to have less dependencies on the old subdivision surface code
which ideally will be removed soon.

The title says it pretty much all: the shrinkwrap modifier is no longer
dependent on the legacy DerivedMesh.
The benefits for doing this are:
- The DerivedMesh is closer to be removed from the codebase.
- Only base vertices are subdivided which could result in better
performance and memory usage.
- Proper crease support (for edges and vertices).
The downside of using OpenSubdiv is that the topology refiner might be
expensive to calculate, so for meshes with a lot of extraordinary faces
(such as n-gons, triangles) the performance will be worse.

Mixing dynamic data with other data always results in dynamic now. While this
wasn't true without lists, it is true now and also makes sense generally. Also
mixing lists and single values or fields results in a list now.

This removes the `STRIP_DUPE_UNIQUE_NAME` and `STRIP_DUPE_ALL` macros
and replaces them with an `enum StripDuplicate`.
A flag with a value of 0 was implicitly used as "duplicate selected strips" so the
enum uses `Selected = 0` to document this behavior better.

The repeat zone color is changed back to the color it used in 4.5, to
avoid the need for people to re-learn the color. The closure socket and
zone share the same color, which is made more yellow-ish to distinguish
it from the bundle socket color.
This is fundamentally quadratic code until #140907 is implemented. However, the
old approach that didn't use `StringRef` was a few percent faster because it
didn't have to call `strlen` as often. So this brings back a little bit of
performance in cases like #140706.

This PR adds a flag to the pose bone that determines its visibility.
Doing so allows to hide a pose bone and
* don't affect other instances of the same armature
* save the visibility even if the rig is linked
The visibility of the bone in object mode is now also determined by the
pose bone whereas before it was the `Bone`.
**This breaks backwards compatibility** on the Python API since the visibility property,
on the `Bone` behaves differently now as it hides the edit bone instead of the pose bone.
In order to remove all active uses of `BONE_HIDDEN_P` the changes in `armature_skinning.cc` are required.

This patch redesigns the File Output node to provide better UX and UI.
This is mainly achieved by allowing the user to create inputs by
dragging into an Extend socket and adjust existing inputs using the
familiar UI list design available in Blender. Additionally, various UI
changes were done:
- The Use Node Format option was renamed to Override Node Format for
clarity.
- Socket types are now fixed and do not change as new links are made,
allowing users to specify the exact output type and employ implicit
conversion if needed.
- The distinction between images and Multi-Layer EXR was made clearer.
- Final output paths are drawn in the UI to remove guess work.
- The Base Path was split into a Directory and a File Name.
- Panels were added to group options, include a panel for the node
format, items, and item formats.

This patch improves warnings displayed when the user attempts to use
passes in render engines other than EEVEE with the viewport compositor.
Previously, an error icon was always displayed if the viewport
compositor was in use as well as a viewport overlay text. This error
existed even when the render engine was set to EEVEE and even if the
passes are not actually used, which was always confusing for users.
This patch improves this by only displaying the error when a pass is
actually used and when a non-EEVEE render engine is used.
This is implemented internally as an extra info callback for the node.
And the compositor_unsupported_message member hack was removed.

Replaces the `FPS` macro with `scene->frames_per_second()`.

* It hides that it depends on a `Scene *` variable named `scene`.
* It makes debugging harder.

Temporary directory handling had a logical error, assuming the
"session" temporary directory was owned and created by Blender
and could be recursively removed on exit.
However, it's possible creating the session sub-directory fails,
in that case the temporary directory was used for the "session".
This meant setting `C:\` as the temporary directory in the preferences
would attempt to recursively remove `C:\` on exit.
Resolve with the following changes:
- Only perform a recursive removal on the temporary directory
if a session sub-directory was created.
- If the creating the user-preferences temporary "session" sub-directory
fails fall back to the systems temporary directory and try to
create the "session" directory there.
Previously this was only done if the preference path didn't exist.
The preferences path was still used if it existed but couldn't be
written to.
Include a test to ensure this is working as expected.
