this is a followup to rB2bd85d9cc623, we cannot forcefully delete
obsolete overrides of object data (meshes etc.), as this implies also
deleting their user object, which might still be a perfectly valid
override, albeit in conflict regarding its obdata ID pointer...
This is the opposite of previous code, which would keep those
'deprecated' overrides arround (often in a dedicated collection), when
they were detected as user-edited.
While this is a safe-ish way to (try to) preserve user-edited data, this
tends to add too much 'trash' data to production scenes, which cleaning
becomes a burden.
Note that user will get warnings in thos cases, and can always choose
not to save the current blend file and go fix the library issue instead.
Code detecting overrides which reference linked data is missing was
actually missing many cases, leading to too much garbage data being kept
around after resync process.
This node has the same functionality as the color and vector curve
mapping nodes in the shader editor. Here is works on every value for
the selected attribute, and it can also output a float value. Other
than that, the implementation is quite straightforward-- almost
completely boilerplate code.

The check to include particle edit mode in the object-mode drop-down

Share the check between both functions.
Fix trying to use cross product on parallel vectors.
Fix intersection checks failing because we run into floating point
issues with very small numbers.
One of current annoying limitations of Blender re Collections/Objects is
that objects are forbidden to not be instantiated in at least one
collection.
Code ensuring that as a pst-processing step of override creation/resync
operations would be a bit too eager to add those objects to an external
'ad-hoc' collection, which poses several issues (both in term of keeping
the scene well organized, and related to override hierarchy handling).
So now be very conservative and only generate and use external 'storage'
collection for those objects when it is absolutely mandatory.
In pratice, it means this should never happen anymore on any decently
organized data source.
Caused by {rB0d9f79b163ee}.
IDP_SyncGroupTypes was now syncing from src to src (leading to
unexpected operator properties).
Assume this is rather critical, dont know the part of the code well, but
above commit clearly shows a change from 'dest->data.group' to 'src-
>data.group' which shouldnt be there.

Not all python-defined ID properties are overridable (yet), this needs
to be detected by libquery 'foreach id' code, such that those ID
pointers can be ignored by override code when working on override
hierarchies.
Fixes part of the issues found while investigating studio files (namely,
some py-defined ID pointer properties from rigify that are not currently
overridable would cause issues and false detections during resync).
Move the detection/decision of whether an ID pointer should be taken
into account in library override hierarchy processing to the LibQuery
area of code, by introducing a new callback flag.
This allows to factorize the test logic, be explicit in liboverride code
about ID relationships that can be ignored when exploring the override
hierarchy, and adds the possibility to do more checks about pointers to
be tagged as non-overridable in the future.
Note that all but the 'special' ID pointers (loop-back, embedded, etc.)
should be overridable. If some is not, relevant IDType 'foreach_id'
callback code is reponsible to tag it properly.
Python-defined IDProperties however are not systematicaly overridable
(yet), so this should allow us to detect that case and act accordingly
in an incomming commit.
No behavioral change expected in this commit.
This patch makes the spline tilts (interpolated to the evaluated points)
affect the evaluated normals, allowing manual control of the rotation of
each profile in the curve to mesh node.
The method is based on Animation Nodes code, which keeps the data in
direction vector form, and rotates around the tangent vector.

While the method of interpolating based on the curve length at each
evaluated point may be useful in some situations, for now it's best to
be consistent with the existing methods in Blender, so this commit adds
a simple linear-based-on-resolution sampling method to bezier splines.
The special case for the interpolation to the last point was being used
for every point in the last segment, because of the rounding. Instead,
make the function slightly more complicated to properly handle the
correct interolation in the cyclic and non-cyclic cases.
Internally, when using Fill brush a dilate of the filled area was done, but this was hardcoded to 1 pixel.
In some situations, this was not enough, so now the value is accesible in the UI and can be set with different values.
Also, as this value is more used than `Leak Size`, the new Dilate is on Topbar, and Leak Size has been moved to Advanced panel.
In my previous patch https://developer.blender.org/D10171 some code changing the direction the strokes normal was accidentally included. This patch reverts that back to the original normal calculation.

After copying NLA tracks from one `AnimData` to another, also ensure
that the `AnimData::act_track` and `AnimData::actstrip` pointers are
pointing to the copy rather than the original.
This is a necessary step to allow library overrides on NLA modifiers
without crashing Blender.
The remapping of the pointers is done by looping over the tracks/strips
and comparing pointers. Alternatively, I could update the copy functions
themselves to keep track of those pointers and return them, but IMO that
would produce more spaghetti (they're also used in cases where this
pointer-remapping is not desired).
Text data block were not considered special in the recursive purge
function. So they would get deleted if they had no actual users.
To fix this we instead make text data block use "fake user" so that
addon authors can specify script files that should be removed if nothing
is using it anymore.
Per default, new text object have "fake user" set. So functionality
wise, the user has to explicitly specify that they want the text object
to be purge-able.

The main goal of this refactor is to not store Object/Collection
pointers for every individual instance. Instead instances now
store a handle for the referenced data. The actual Object/Collection
pointers are stored in a new `InstanceReference` class.
This refactor also allows for some better optimizations further down
the line, because one does not have to search through all instances
anymore to find what data is instanced.
Furthermore, this refactor makes it easier to support instancing
`GeometrySet` or any other data that has to be owned by the
`InstancesComponent`.

This patch adds initial curve support to geometry nodes. Currently
there is only one node available, the "Curve to Mesh" node, T87428.
However, the aim of the changes here is larger than just supporting
curve data in nodes-- it also uses the opportunity to add better spline
data structures, intended to replace the existing curve evaluation code.
The curve code in Blender is quite old, and it's generally regarded as
some of the messiest, hardest-to-understand code as well. The classes
in `BKE_spline.hh` aim to be faster, more extensible, and much more
easily understandable. Further explanation can be found in comments in
that file.
Initial builtin spline attributes are supported-- reading and writing
from the `cyclic` and `resolution` attributes works with any of the
attribute nodes. Also, only Z-up normal calculation is implemented
at the moment, and tilts do not apply yet.
**Limitations**
- For now, you must bring curves into the node tree with an "Object
Info" node. Changes to the curve modifier stack will come later.
- Converting to a mesh is necessary to visualize the curve data.
Further progress can be tracked in: T87245

Using scene frame 1 is not reliable in cases when there is a
frame offset is involved. Using frame 1 seems more reliable,
although might still fail under certain circumstances.
More reliable fix would require a deeper change in the data
structure and the logic about frame loading and size detection.
When saving a file in Edit mode with Multiframe enabled, the render did not include the modifiers.
Now the multiframe is not enabled if it's doing a render.
Multi-overrides of a same linked ID in a same override hierarchy are
currently not supported and can cause all kind of issues.
In some cases they could lead to infinite loop trying to resync the same
ID over and over, this is now prevented.
Found in some Blender studio production files.
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.

This adds a callback to bNodeTreeType to check which socket types are
valid for the tree type. Function has been implemented for the normal
tree types, and can be implemented for custom node trees with python,
by adding a `classmethod` to the tree. However, only builtin socket
types are supported.
This is relevant for T87049, but it also has the advantage that it is
now clear which node trees support which sockets. Previously this
was assumed to be known by all developers.
