Remove the 'only_face_normals' argument.
- BKE_mesh_calc_normals_poly for polygon normals.
- BKE_mesh_calc_normals_poly_and_vertex for poly and vertex normals.
Order arguments logically:
- Pair array and length arguments.
- Position normal array arguments (to be filled) last.
The crash occurred calling because mesh_get_eval_final in edit-mode
freed all derived mesh data without tagging the object for updating.
However meshes in edit-mode weren't meant to be used as knife-project
source-data, adding support for multi object edit-mode caused this.
Loopcut drawing from gizmo had thicker lines because
it was using line smoothing without alpha blend, compared
to thin jagged lines from operator.
Make the drawing anti aliased and consistent by using
3D_POLYLINE/3D_POINT shaders, and making sure alpha
blending is on.

While this was already the case for the most part
some selection operators stored common settings for reuse such as
"toggle", "extend" & "deselect".
Disabling storing these settings for later execution
as it means failure to set these options in the key-map re-uses
the value of the shortcut that was last called.
Skip saving these settings since this is a case where reusing them
isn't helpful.
Resolves T90275.
Only the "changed" state from the last edit-object was used,
this meant the operator would not perform the necessary update
with multi-object edit-mode.
Use "changed" & "changed_multi" naming convention.
Setting normals from faces wasn't weighting the faces contribution
by the corner angle, giving lop-sided results in some cases.
This removes the epsilon check for CLNORS_VALID_VEC_LEN,
in favor of matching the behavior of vertex normals exactly.
This was reported in T90026 for attributes, but was also true for:
- UVMaps
- Vertex Colors
- Sculpt Vertex Colors
- Face Maps
For Vertex groups and Shapekeys this was already done (in that their
remove poll would check if there is a vertex group or shapekey to begin
with), now make this consistent across all mentioned types.
Thx @vvv for the initial patch (where this was done for attributes only)

No operator or macro should be missing description. But if they do, then
they should use NULL pointer, and not an empty string.
This behavior was already enforced (through an assert) for operators,
previous commit made it the same for macros.
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

- Tag the object data instead of the object when decoding
(this avoids duplicating mesh object-data on each undo-step).
- Calculate face normals as part of multi-threaded tessellation.
This gives ~11% speedup with 1.5x million polygons.
Rename:
- EDBM_mesh_free -> EDBM_mesh_free_data
BKE_editmesh_free -> BKE_editmesh_free_data
Since this doesn't free the edit-mesh pointer.
- BKE_editmesh_free_derivedmesh -> BKE_editmesh_free_derived_caches
Since this no longer uses derived-mesh, match naming for the related
object function BKE_object_free_derived_caches.
Also remove `do_tessellate` argument from BKE_editmesh_create,
since the caller can explicitly do this if it's needed,
with the advantage that it can be combined with normal calculation
which is faster on high-poly meshes.
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.
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.
Avoid computationally expensive copying operations
when only some settings have been modified.
This is done by adding support for updating parameters
without tagging for copy-on-write.
Currently only mesh data blocks are supported,
other data-blocks can be added individually.
This prepares for changing values such as edit-mesh auto-smooth angle
in edit-mode without duplicating all mesh-data.
The benefit will only be seen when the user interface no longer tags
all ID's for copy on write updates.
ID_RECALC_GEOMETRY_ALL_MODES has been added to support situations
where non edit-mode geometry is modified in edit-mode.
While this isn't something user are likely to do,
Python scripts may change the underlying mesh.

This resolves a long standing bug in edge selection
(picking, circle, box & lasso).
Now when one of the edges vertices fails to project into screen space,
the edge is clipped by the viewport to calculate an on-screen location
that can be used instead.
This isn't default as it may be important for the on the screen location
not to be clipped by the viewport.
This patch ensures that selection mode flushing updates total selection
counts internally. This reduces recounting when we are sure that the
input total selection counts were up to date.
For example for circle selection the total selection counts were
correct. But during flushing the selection could have been changed and
therefore the selection was always recounted.
This increased the performance on selected system from 6.90 FPS to 8.25
FPS during circle selection operations.

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.
There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.
Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading
Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.
Patch implemented by Sergey and me.
