Store library filepath so we can find the right datablock.
Tested to work with the brush assets project branch, as this
currently does not affect anything in main.

I found that `packedmap` is effectively unused when I worked on #123243.
The only function that wrote to it was `blo_make_packed_pointer_map`
and that is never called. Packed data already used the normal `datamap` as fallback.

Avoid logging actions about `action->idroot` not matching, when evaluating
the NLA and visiting a layered Action. Layered Actions are not limited to
a single data-block type, and so the code should ignore `action->idroot`.
Add layered Action support to `BKE_action_frame_range_calc()`, by
looping over all F-Curves of all Bindings in the Action.
Introduce `animrig::fcurves_all(action)`, which returns a vector of all
F-Curves in the Action, both for legacy and layered Actions.
No functional changes for legacy Actions.
Part of #118145.
Use the recently added utility for base mesh data, and for BMesh and
multires add a compromise that gets some benefits of simpler loops
but still avoids some duplication.
Also add move a recently added utility to only affect visible grid
vertices to the relevant header and reuse it. I expect this won't be a
permanent part of the API but for now it's better than duplicating
all the loops twice.
For base mesh sculpting, we already draw the original data instead of the
evaluated data, so the evaluated mesh doesn't have to be updated to
contain the new attribute. This is different from multires sculpting
because sculpt brushes and drawing only deal with the evaluated
SubdivCCG, not the original multires modifier data. Removing the
unnecessary update removes a noticeable pause when clearing and
adding a mask.
This adds additional logic to `GreasePencil::rename_node` to rename
the strings in the modifier influence data.
This is similar to how `ED_armature_bone_rename` handles renaming of
strings.
Resolves#123321.

This fixes#121695. `float4x4` matrices are generally expected to be 16 byte aligned.
Currently, there is no mechanism (afaik) that allows allocating these overaligned types
when loading files from disk. This patch adds an array with alignment information for
each type in `SDNA`. Currently, the alignment is just `__STDCPP_DEFAULT_NEW_ALIGNMENT__`
for all types and is manually set for the `mat4x4f` DNA type. The .blend file format is
not changed at all. The alignment information is purely runtime data.
In the future it would probably be good to generalize this a bit more instead of
hardcoding the alignment for `mat4x4f`, but would make it unnecessarily complex for
now because this is intended for the release branch.

This patch implements a new Gabor noise node based on [1] but with the
improvements from [2] and the phasor formulation from [3].
We compare with the most popular existing implementation, that of OSL,
from the user's point of view:
- This implementation produces C1 continuous noise as opposed to the
non continuous OSL implementation, so it can be used for bump
mapping and is generally smother. This is achieved by windowing the
Gabor kernel using a Hann window.
- The Bandwidth input of OSL was hard-coded to 1 and was replaced with
a frequency input, which OSL hard codes to 2, since frequency is
more natural to control. This is even more true now that that Gabor
kernel is windowed as opposed to truncated, which means increasing
the bandwidth will just turn the Gaussian component of the Gabor
into a Hann window. While decreasing the bandwidth will eliminate
the harmonic from the Gabor kernel, which is the point of Gabor
noise.
- OSL had three discrete modes of operation for orienting the kernel.
Anisotropic, Isotropic, and a hybrid mode. While this implementation
provides a continuous Anisotropy parameter which users are already
familiar with from the Glossy BSDF node.
- This implementation provides not just the Gabor noise value, but
also its phase and intensity components. The Gabor noise value is
basically sin(phase) * intensity, but the phase is arguably more
useful since it does not suffer from the low contrast issues that
Gabor suffers from. While the intensity is useful to hide the
singularities in the phase.
- This implementation converges faster that OSL's relative to the
impulse count, so we fix the impulses count to 8 for simplicitly.
- This implementation does not implement anisotropic filtering.
Future improvements to the node includes implementing surface noise and
filtering. As well as extending the spectral control of the noise,
either by providing specialized kernels as was done in #110802, or by
providing some more procedural control over the frequencies of the
Gabor.

This adds a "Legacy Behavior" option to the Limit Rotation constraint that makes
it behave how Limit Rotation constraints did prior to
ed2408400d. Newly created constraints have this
option disabled, but versioning code enables the option on constraints from
older files to ensure that the behavior of e.g. existing rigs is not altered.
This is one part of a two-part fix for #123105. The other part is in PR
extensions/rigify#4.

The current temperature unit adjusts to Celsius or Fahrenheit based on
unit system, but specifically for color temperatures the convention is
to display them in Kelvin, and it'd be strange to e.g. see 11240°F when
opening the white balance panel.
Therefore, this adds a dedicated Color Temperature unit, and uses it
for the two existing blackbody temperature inputs in shader nodes.

When copying a local ID into a library, or a linked ID into a different
library, the 'linked' tags would not be properly preserved or set, and
the relative file paths would not be properly remapped.
These issues were not currently exposed (no existing code could trigger
them), but some of these fixes are needed for upcoming refactor of the
partial write code.
NOTE: not very happy with the split in library handling between
`BKE_id_copy_in_lib` and `BKE_libblock_copy_in_lib`, this will have to
be solved at some point.

Currently the corner_vert and corner_edge attributes go through the
generic custom data interpolation, only to be overwritten directly
afterwards. In a profile of the execution of the subdivision surface
modifier, 5% of the time was spent in `layerInterp_propInt`. To fix
this, first build a `CustomData` layout to be used just for face corner
attribute interpolation. Then allocate the topology attributes
separately and add them to the result mesh later. This requires a fair
amount of boilerplate right now, but it should be improved with various
changes to mesh attribute storage in the future.
In a file with many object with a subsurf modifier, this change
improved the overall execution time by between 5 and 10% in my tests.

The issue was that we used `from_orthonormal_axes` which obviously expects that
the axes are orthonormal. However, with custom curve normals this is not always the
case. Math wise, an additional normalization is necessary because the cross product
is not automatically normalized anymore.
This change also means that `point_matrix` may have a shearing component. But I
think that's fine here because the matrix is only immediately applied on vertex positions.
This shouldn't affect any case where the normal and tangent are orthonormal.

The issue was a floating point precision issue
between the number of the cycle and the time
within the cycle (`cycle` and `cyct`).
Due to that the `cycle` would advance to the
next whole number while the `cycle time`
is still slightly under that.
This is fixed by calculating the `cycle` with double precision.
This has a measurable performance
impact (for `fcm_cycles_time`)

For fcurves with a cycle modifier,
this code is run at every evaluate call.
The only time when that would be an issue is
in the graph editor, where there is an evaluate
call for roughly every pixel for curves that have a modifier.
However even in that scenario the performance
is the same within run to run variance (for `graph_draw_curves`)

This implements (most of) the proposal in #122743:
* Add a new `IDP_FLAG_STATIC_TYPE` IDProperty flag.
* Update `BPy_IDProperty_Map_ValidateAndCreate` and related to never
change an existing property type if statically typed.
The biggest change happens in bpy assignement code, since instead of
replacing the old exisitng property by a newly created one, and copying
over a few settings, now the old property is kept if possible, and a new
one is only created if needed.
And in case the existing property is statically typed, if it cannot be
re-used to store the given value, and error is reported and it remains
unchanged.
`IDP_ARRAY` is also supported for basic numeric types, so 'vector'
properties and such work as expected. Lentgh is considered as part of
the static type (i.e. one can only assign a 3 components py sequence to
a 3-len array property, etc.).
Such in-place update is not yet implemented for `IDP_IDPARRAY` and
`IDP_GROUP` types. While important (especially the group one), they are
not that critical for the current issues related to changing IDProperty
types.
Masks are not updated when edited when using the GPU compositor. That's
because the GPU compositor caches static resources and invalidates them
according to the recalculate flags that the depsgraph flushes to IDs.
The issue is that the flags are not flushed to the evaluated IDs of the
compositor depsgraph, but rather to some other evaluated versions of the
IDs.
To fix this, we make the compositor depsgraph persistent and store it in
the scene runtime. This allows us to reliably track changes to resources
used by the compositor and also reduces the overhead of depsgraph
creation in the compositor job.
Patch originally provided by Sergey.
Fixes#121188.

This patch removes the Auto Render option from the compositor. This is
done for the following reason:
- The option didn't really work except in the case of transforming an
object. So it wasn't really reliable.
- It made little sense to use since the introduction of the Viewport
Compositor.
- It had a number of UX issues, including the fact that it can't be used
with animation playback, and the fact that rendering can get in the
way of the UI depending on the preferences for temporary editors.

The documentation of some of `BKE_animsys_nla_remap_keyframe_values()`'s output
parameters were unclear/misleading, in particular making it unclear how those
output parameters should be used/interpreted by calling code.
This commit attempts to improve that, in particular trying to make it clearer
what actions calling code can/should take based on the returned output
parameters.

This type was not necessary because `ptr_` is allowed to
be `nullptr`. This also means that we don't need to handle
the `None` case in switch statements. We assume that at
this point the owner is valid.
Previously these were shown as missing add-ons, since they have been
intentionally removed, remove them as part of versioning instead
of showing them as "Missing Add-ons". This is especially important
for X3D & STL which were enabled by default which meant any user
loading 4.1 preferences would have them shown as missing add-ons.
