The Exact boolean used in the cell fracture addon incorrectly
kept some outside faces: due to some raycasts going into open
eye socket then out of the head, leading to one ray direction
(out of 8) saying the face was inside the head. The current
code allowed 1 of 8 rays only as "inside" to accommodate the
case of a plane used in boolean to bisect. But this cell fracture
case needs more confidence of being inside. So changed the
test for intersection to require at least 3 of 8 rays to be inside.
Maybe the number of rays to indicate insideness should be exposed
as an option, to allow user tuning according to the degree of
"non-volumeness" of the arguments, but will try at least for now
to magically guess the right value of the rays-inside threshold.
Note: all of this only for the case where the arguments are not
all PWN (approx: manifold). The all-PWN case doesn't use raycast.
Instead of returning a raw pointer, `LinearAllocator.construct(...)` now returns
a `destruct_ptr`, which is similar to `unique_ptr`, but does not deallocate
the memory and only calls the destructor instead.
The main change is that large allocations are done separately now.
Also, buffers that small allocations are packed into, have a maximum
size now. Using larger buffers does not really provider performance
benefits, but increases wasted memory.
This is a complete rewrite of the derived node tree data structure.
It is a much thinner abstraction about `NodeTreeRef` than before.
This gives the user of the derived node tree more control and allows
for greater introspection capabilities (e.g. before muted nodes were
completely abstracted away; this was convenient, but came with
limitations).
Another nice benefit of the new structure is that it is much cheaper
to build, because it does not inline all nodes and sockets in nested
node groups.

This attribute exposes mesh vertex normals as a `vertex_normal`
attribute for use with nodes. Since the normal vector stored in
vertices is only a cache of data computable from the surrounding faces,
the attribute is read-only. A proper error message for attempting to
write this attribute is part of T85749. A write-only normal attribute
will likely come later, most likely called `corner_normal`.
The normals are recomputed before reading if they are marked dirty.
This involves const write-access to the mesh, protected by the mutex
stored in `Mesh_Runtime`. This is essential for correct behavior after
nodes like "Edge Split" or nodes that adjust the position attribute.

Because the search didn't run when the menu first opens, the attributes
appeared in a different order than after you typed anything into the
search field. This commit instead runs the search when the menu
is first opened, but it only sorts items without filtering.

This prepares things so we can start porting the individual ID types to
the new code design. I already added some code for library IDs, because
they need some special handling during construction, which I didn't want
to break.
The `AbstractTreeElement::isExpandValid()` check can be removed once
types were ported and can be assumed to have a proper `expand()`
implemenation.
Also makes `TreeElementGPencilLayer` `final` which I forgot in
e0442a955b.
Mistake in aa3a4973a3. The expanded `ELEM()` check would include
`0 && te->idcode != 0`, which always evaluates to `false`/`0`. That
wouldn't cause the asset to fail, but the `te->idcode` part would never
be checked.
Fixed the error and cleaned up the check against "0" with a check
against `TSE_SOME_ID`, see b9e54566e3.
Code to check if the Outliner tree-element type was the general ID one
would always check against "0" (explicity or even implicitly). For
somebody unfamiliar with the code this is very confusing. Instead the
value should be given a name, e.g. through an enum.
Adds `TSE_SOME_ID` as the "default" ID tree-element type. Other types
may still represent IDs, as I explained in a comment at the definition.
There may also still be cases where the type is checked against "0". I
noted in the comment that such cases should be cleaned up if found.
Add `BKE_pose_apply_action(object, action, anim_eval_context)` function
and expose in RNA as `Pose.apply_action(action, evaluation_time)`.
This makes it possible to do the following:
- Have a rig in pose mode.
- Select a subset of the bones.
- Have some Action loaded that contains the pose you want to apply.
- Run `C.object.pose.apply_pose_from_action(D.actions['PoseName'])`
- The selected bones are now posed as determined by the Action.
Just like Blender's current pose library, having no bones selected acts
the same as having all bones selected.

Add an RNA function `activate_asset_by_id(asset_id: ID, deferred: bool)`
to the File Browser space type, which intended to be used to activate an
asset's entry as identified by its `ID *`. Calling it changes the active
asset, but only if the given ID can actually be found.
The activation can be deferred (by passing `deferred=True`) until the
next refresh operation has finished. This is necessary when an asset has
just been added, as it will be loaded by the filebrowser in a background
job.

Is based on Google style which was used in the Libmv project before,
but is now consistently applied for the sources of the library itself
and to C-API. With some time C-API will likely be removed, and it
makes it easier to make it follow Libmv style, hence the diversion
from Blender's style.
There are quite some exceptions (clang-format off) in the code around
Eigen matrix initialization. It is rather annoying, and there could be
some neat way to make initialization readable without such exception.
Could be some places where loss of readability in matrix initialization
got lost as the change is quite big. If this has happened it is easier
to address readability once actually working on the code.
This change allowed to spot some missing header guards, so that's nice.
Doing it in bundled version, as the upstream library needs to have some
of the recent development ported over from bundle to upstream.
There should be no functional changes.
Continuation of work in 2e221de4ce and 249e4df110. Now the tree-element
types have to be ported one by one. This is probably the most straight forward
type to port.

In general, I could not find a reason executing from the python console
should not do an Undo push. Running a script from the Text Editor does
this as well and this seems generally useful.
Without an Undo push, one can easily run into situations were IDs have
been added or removed and undo on would then cause trouble (e.g. first
selection then bpy.ops.object.duplicate() -- this crashed as reported in
T86293 -- duplicate does not get its own undo push because it is not the
last op in the list, wm->op_undo_depth is not zero). This has changed
with the Undo refactor, so in essence the root cause is the same as
T77557, Legacy Undo does not suffer from the crash (but misses
the generally useful undo push from the console still)
Now add Undo to CONSOLE_OT_execute bl_options ('UNDO_GROUPED' seems more
appropriate than plain 'UNDO' since pasting multiple lines of code will
call CONSOLE_OT_execute multiple times in a row).
