Note that this name is essentially never used anywhere, besides as 'information'
mostly accessible from python console. Those embedded IDs are not in Main, so they
are not accessible by name ever, and mostly unusable from animation perspective
(either drivers or fcurves).
Therefore, no breakage is expected in user scripts or addons, nor when
loading in older versions of Blender.

From patch D11780 from Erik Abrahamsson.
It parallelizes making the vertices, destruction of map entries,
finding if the result is PWN, finding triangle adjacencies,
and finding the ambient cell.
The latter needs a parallel_reduce from tbb, so added one into
BLI_task.hh so that if WITH_TBB is false, the code will still work.
On Erik's 6-core machine, the elapsed time went from 17.5s to 11.8s
(33% faster) on an intersection of two spheres with 3.1M faces.
On Howard's 24-core machine, the elapsed time went from 18.7s to 10.8s
for the same test.
Also replace integer with bool in Ghost API when only used as boolean,
and uint8* with char* in Ghost API when variable is a string.

This node creates a poly spline line in one of 2 modes:
- Line between two points
- Start Point, Direction, and Length
Both modes create splines with only start and endpoints.
A resample node can be used afterward to increase the point count.

This patch adds a very simple node that explicitly converts a float to
an int. While this may seem redundant, it would offer 2 benefits to the
current requirement to use implicit float conversions:
1. It makes the node tree's intent more clear and self-documenting
(especially if changes in the future require integer inputs).
2. It eliminates undefined behavior in current/future nodes from float
inputs by guaranteeing that the input is an integer.
The node offers a variety of rounding techniques to make it more flexible.

This would prevent loading a parent that would only be referenced by
children during a linking operation.
Looks like this missing bit of code has been there since the stone ages,
it is fairly baffling to find that such critical low-levels mistakes can
survive decades in a codebase...
Note that such fully-indirectly linked parent object is not instantiated
in scene currently, this is fairly bad I think, but kind of a different
issue.
This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.
Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.
As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.
There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
viewer nodes.
* Less visual clutter in node headers.

Using BMesh operators through the edit-mesh API created a full copy
of the mesh so it was possible to restore the mesh in case
one of the operators raised an error.
Remove support for automatic backup/restore from the EDBM_op_* API's
as it adds significant overhead and was rarely used.
Operators that need this can use the BMBackup API to backup & restore
the mesh in case of failure.
Add warning levels to BMO_error_raise so operators can report problems
without it being interpreted as a request to cancel the operation.
For high-poly meshes creating and freeing a full copy is an expensive
operation, removing this gives a speedup of ~1.77x for most operators
except for "connect_verts" / "connect_vert_pair"
which still uses this functionality.
As noted in a comment now, these functions only update a cache, so they
don't change the logical state of the mesh, which is "it will have the
data when necessary." Using a const argument will help const correctness
when accessing an object's evaluated mesh.
Add a new transformation space choice for bone constraints, which
represent the local transformation of the target bone in the constraint
owner's local space.
The use case for this is transferring the local (i.e. excluding the
effect of parents) motion of one bone to another one, while ignoring
the difference between their rest pose orientations.
The new option replaces the following setup:
* A `child` bone of the `target`, rotated the same as `owner` in rest pose.
* A `sibling` bone of the `target`, positioned same as `child` in rest
pose and using Copy Transforms in World Space from `child`.
* The `owner` bone constraint uses Local Space of `sibling`.
(This analogy applies provided both bones use Local Location)

This constraint can be naturally viewed as a prototype for a future
4x4 matrix math node (or subset thereof), since its basic semantics
already is matrix assignment. Thus it makes sense to add math options
to this constraint to increase flexibility in the meantime.
This patch adds support for several operations that would be useful:
- An option to remove shear in the incoming target matrix.
Shear is known to cause issues for various mathematical operations,
so an option to remove it at key points is useful.
Constraints based on Euler like Copy Rotation and Limit Rotation
already have always enabled shear removal built in, because their
math doesn't work correctly with shear.
In the future node system shear removal would be a separate node
(and currently Limit Rotation can be used as a Remove Shear constraint).
However removing shear from the result of the target space conversion
before mixing (similar to Copy Rotation) has to be built into
Copy Transforms itself as an option.
- More ways to combine the target and owner matrices.
Similar to multiple Inherit Scale modes for parenting, there are
multiple ways one may want to combine matrices based on context.
This implements 3 variants for each of the Before/After modes
(one of them already existing).
- Full implements regular matrix multiplication as the most basic
option. The downside is the risk of creating shear.
- Aligned emulates the 'anti-shear' Aligned Inherit Scale mode,
and basically uses Full for location, and Split for rotation/scale.
(This choice already existed.)
- Split Channels combines location, rotation and scale separately.
Looking at D7547 there is demand for Split Channels in some cases,
so I think it makes sense to include it in Copy Transforms too, so that
the Mix menu items can be identical for it and the Action constraint.

Generally the evaluated mesh should not be changed, since that is the
job of the modifier stack. Current code is far from const correct in
that regard. This commit uses a const variable for the reult of
`BKE_object_get_evaluated_mesh` in some cases. The most common
remaining case is retrieving a BVH tree from the mesh.
Normals now includes many functions including normal splitting &
custom normal manipulation split this into it's own file
to centralize related functions.
This node has two modes: the first mode computes a circle from three
locations and a resolution. The second takes radius and resolution.
The first mode also outputs the center of the computed circle as
a vector.

- Ability to snap to playhead and strip hold offset points
- Filter snap points by excluding sound or muted strips
- Control snapping distance

This commit avoids duplicating the deformed control point
list twice by modifying the list in the object curve cache directly.
For curves, the original control point data was duplicated into a
local listbase, deformed, used to create the "bevel list" data, and
then duplicated again for the object-level storage of deformed
control points. Text objects and surface objects had a similar
unnecessary duplication.
The curve bevel list was freed, and then freed again in a call to the
function that recalulates it. The curve "anim path" data was freed
only to be freed again in its calculation function as well. Also move
the anim_path calculation directly after the bevel list creation to
make its requirements more explicit.
Surface objects were already handled by an early return in the main
"curve types" function. This commit splits them, renames the funtions
to match (and be more consistent with other names), and sanitizes the
checking of object types.
Every call to `BKE_displist_make_curveTypes` already checks the object
type beforehand, there is no need to check it again. Also removed an
outdated comment.
`BKE_displist_make_curveTypes` had a `for_orco` argument that was
always false in calls to the function. Removing it allows the curve
displist and modifier evaluation code to become simpler. There are
some related cleanups in rBdf4299465279 and rB93aecd2b8107.
Sometimes the current spline list isn't part of the original curve, like
when using the deformed control points, etc. This will be helpful in
the curve modifier stack.
While the const correctness of `ListBase` is quite limited, it's helpful
to have a way to retrieve the `Nurb` list from curve object data without
casting away const from the curve.
Weird 'embedded for overrides' flag of embedded IDs (including ShapeKeys
in override context) was not properly cleaned up when making an override
fully local.
Reported by studio, thanks.
@jbakker should be backported to 2.93LTS if possible.
* Reduce code duplication.
* Give methods more standardized names (e.g. `move_to_initialized` -> `move_assign`).
* Support wrapping arbitrary C++ types, even those that e.g. are not copyable.
