New `oldnewmap_lib_insert` does nothing special, it just wraps around existing
`oldnewmap_insert`, but it's the logical counter part of `oldnewmap_liblookup`.
It also helps tremendously when debuging complex ID pointers issues in
readfile.c code.
Crash would happen when a linked ID would become missing, that was
'pre-declared' and used only once as a 'weak link' in another library
stored before the one it came from.
In that case, the place-holder generated in read code would be freed in
`read_library_clear_weak_links`, when handling its 'owner' library, but
since all previous libraries in the list had already been 'lib_linked'
and their filedata (and related libmap) freed, the update of the libmaps
in `read_library_clear_weak_links` would not apply to data from those
previous libraries, leading to ID pointers there pointing to freed
memory.
This fix should also be backported to 2.93.
The Python based importer had a special case handling of "no faces in
the whole file at all", where it ended up treating the whole file
as essentially a point-cloud-like object (just loose vertices, no
faces or edges). The new importer code was missing this special case.
Fixes T100017. Added gtest coverage that was failing without the fix.
When plotting equally distant points around a circle support an extra
axis of symmetry so twice as many exact values are repeated than
originally added in [0], see code-comments for a detailed explanation.
Tests to ensure accuracy and exact symmetry have been added too.
Follow up on fix for T87779.

The problem was that zero-sized and non-existant attributes were
handled the same in some parts of the attribute API, which led to
unexpected behavior.
The solution is to properly differentiate the case when an attribute
does not exist and when it is just empty (because the geometry
is empty).

* BLENDER_VERSION_CYCLE set to beta
* Update pipeline_config.yaml to point to 3.2 branches and svn tags
* Update and uncomment BLENDER_VERSION in download.cmake
This name doesn't require understanding of fields, and
is phrased as an action which is consistent with other nodes.
Discussed in the latest geometry nodes sub-module meeting.
This adds three new nodes:
* `Shortest Edge Paths`: Actually finds the shortest paths.
* `Edge Paths to Curves`: Converts the paths to separate curves.
This may generate a quadratic amount of data, making it slow
for large meshes.
* `Edge Paths to Selection`: Generates an edge selection that
contains all edges that are part of a path. This can be used
with the Separate Geometry node to only keep the edges that
are part of a path. For large meshes, this approach can be
much faster than the `Edge Paths to Curves` node, because
less data is created.

Add a version of #BKE_main_namemap_validate that also fixes the issues,
and call it in a do_version to fix recent .blend files saved after the
regression introduced in rB7f8d05131a77.
This is mandatory to fix some production files here at the studio, among
other things.
The function to rearrange channels only works for F-curves channels for now, adding the `FCURVESONLY` filter prevents the function to be called for grease pencil channels, thereby fixing the crash.

Add a util function to check that content of a given Main and the
namemaps in it are consistent.
Add some asserts calling this check after file read, and after some
override operations.
Liboverrides are doing some very low-level manipulation of IDs in apply
code, to reduce over-head of name and sorting handling.
This requires specific care to ensure thatr the new namemap runtime data
remains up-to-date and valid. Otherwise, names of existing IDs would be
missing from the map, which would later lead to having several different
IDs with the same name. Critical corruption in Blender ID management.
Reported by animators at the Blender studio.
Regression from rB7f8d05131a77.
A mistake in the 0dcee6a386 which made specific driven visibility
to work, but did not properly handle actual time-based visibility.
The basic idea of the change is to preserve recalculation flags of
nodes which were tagged for update but were not evaluated due to
visibility constraints. In the file from the report this makes it
so tagging which is done first time ID is in the dependency graph
are handled when the ID actually becomes visible. This is what
solved the root of the problem from the report: there was missing
geometry update since it was "swallowed" by the evaluation during
the object being invisible. In other configurations this change
allows to handle pending geometry updates due to animated modifiers
be handled when object becomes visible without time change.
This change also solves visibility issue of the synchronization
component which also started to be handled badly since the
previous fix attempt. Basically, the needed exception in its
visibility handling did not happen and a regular logic was used
for it.
Tested with files from the T99733, T99976, and from the Heist
project.

It was never added for the field on domain and field at index nodes.
They need special handling because they have many what should be
a multi-type socket declaration.
This patch adds a `mute` RNA property on `ActionGroup`s that allows them to be easily muted/unmuted from python.
This uses the existing `AGRP_MUTED` flag which was also accessible from the user interface.

Previously there was a special extraction process for "vertex colors"
that copied the color data to the GPU with a special format. Instead,
this patch replaces this with use of the generic attribute extraction.
This reduces the number of code paths, allowing easier optimization
in the future.
To make it possible to use the generic extraction system for attributes
but also assign aliases for use by shaders, some changes are necessary.
First, the GPU material attribute can now store whether it actually refers
to the default color attribute, rather than a specific name. This replaces
the hack to use `CD_MCOL` in the color attribute shader node. Second,
the extraction code checks the names against the default and active
names and assigns aliases if the request corresponds to a special active
attribute. Finally, support for byte color attributes was added to the
generic attribute extraction.

Changing the value doesn't accomplish anything, since the retrieved
value would be the same for every index then. So it's best to hide it
to make the node clearer.
The Graph, Driver, and Dopesheet's (and sub modes) properties panel
(N-Panel) are now open by default. This includes the editors in the
default Animation workspace.
Note that, because the Timeline is implemented as a special mode of the
Dopesheet, switching between Timeline and Dopesheet will *not* change
the visibility of the properties panel.

`parallel_invoke` allows executing functions on separate threads.
However, creating tasks in tbb has a measurable amount of overhead.
Therefore, it can be benefitial to disable parallelization when
the amount of work done per function is small.

The stroke points were changed but the bounding box calculation was not done and this produced a problem in any bounding box check done by different tools.
Any script that raised a SystemExit called by --python, --python-expr
command line args or by executing the text block would exit without
printing a message. This caused the error from T99966 to be hidden.
Add explicit handling for SystemExit to ensure the message is always
shown before exiting.
More details noted in code-comments.
There is a 1 pixel error in the size registered for the buffer
dimensions.
NOTE: This issue indicates that the texture scale is different from the
region, so the mouse-based coordinates used are actually misaligned.
This misalignment will be fixed in another commit.

The "snap to surface" operators now have "disabled" poll messages
when there is no surface object.
The implementation in most curves operators is also unified.
The goal is to avoid having to define and use the poll failure messages
in multiple places, to reduce the boilerplate that tends to be
necessary to add an operator, and to increase the likelihood that
operators are implemented with proper poll messages.
