Currently, whenever any BMesh is converted to a Mesh (except for edit
mode switching), original index (`CD_ORIGINDEX`) layers are added.
This is incorrect, because many operations just convert some Mesh into
a BMesh and then back, but they shouldn't make any assumption about
where their input mesh came from. It might even come from a primitive
in geometry nodes, where there are no original indices at all.
Conceptually, mesh original indices should be filled by the modifier
stack when first creating the evaluated mesh. So that's where they're
moved in this patch. A separate function now fills the indices with their
default (0,1,2,3...) values. The way the mesh wrapper system defers
the BMesh to Mesh conversion makes this a bit less obvious though.
The old behavior is incorrect, but it's also slower, because three
arrays the size of the mesh's vertices, edges, and faces had to be
allocated and filled during the BMesh to Mesh conversion, which just
ends up putting more pressure on the cache. In the many cases where
original indices aren't used, I measured an **8% speedup** for the
conversion (from 76.5ms to 70.7ms).
Generally there is an assumption that BMesh is "original" and Mesh is
"evaluated". After this patch, that assumption isn't quite as strong,
but it still exists for two reasons. First, original indices are added
whenever converting a BMesh "wrapper" to a Mesh. Second, original
indices are not added to the BMesh at the beginning of evaluation,
which assumes that every BMesh in the viewport is original and doesn't
need the mapping.

This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

When removing a node that has a dependence on an ID, like the object
info node, the dependency graph relations weren't updated. This can
cause unexpected performance issues if a complex node tree continues
to depend on an ID that it doesn't actually use anymore. To fix this case,
tag relations for an update if the node has a data-block socket.

While this should not happen in theory, very bad/broken/dirty files can
lead to such situations.
So we need to re-ensure valid root IDs after resync (for now, done after
each 'library indirect level' pass of resync, this may not be 100%
bulletproof though, time will say).

In some cases broken files could lead to selecting a shapekey as

This adds initial support for edit mode for the experimental new curves

This patch also adds empty menus in edit mode. Those were added mainly
to quiet warnings as the menus are programmatically added to the edit
mode based on the object type and context.

- No need for `normal_tx` array if we normalize the planes in `plane_tx`.
- No need to calculate the distance squared to a plane (with `dist_signed_squared_to_plane_v3`) if the plane is normalized. `plane_point_side_v3` gets the real distance, accurately, efficiently and also signed.
So normalize the planes of the member `CameraViewFrameData::plane_tx`.

The general idea here is to wrap the `CurvesGeometry` DNA struct
with a C++ class that can do most of the heavy lifting for the curve
geometry. Using a C++ class allows easier ways to group methods, easier
const correctness, and code that's more readable and faster to write.
This way, it works much more like a version of `CurveEval` that uses
more efficient attribute storage.
This commit adds the structure of some yet-to-be-implemented code,
the largest thing being mutexes and vectors meant to hold lazily
calculated evaluated positions, tangents, and normals. That part might
change slightly, but it's helpful to be able to see the direction this
commit is aiming in. In particular, the inherently single-threaded
accumulated lengths and Bezier evaluated point offsets might be cached.

Fix possible overflow of Modifier UUID
The code prior this change was re-generating modifier's session UUID
prior to copying this id from the source. This approach has a higher
risk of modifiers session UUID to overflow and start colliding with
existing modifiers.
This change makes it so that modifier copy does not re-generated the
session UUID unless it is needed.

Due to recent changes there have been reports of incorrect loading of
GPU textures. This fix reverts a part of {D13238} that might be the
source of the issue.
Although rB56407432a6a did fix missing subdivision in some cases, in
other cases it did not return the mesh wrapper (like when using
autosmooth, which requires a copy of the mesh), so the non-subdivided
mesh was still returned.
This patch reverses the dependency between `BLI_math_vec_types.hh` and
`BLI_math_vector.hh`. Now the higher level `blender::math` functions
depend on the header that defines the types they work with, rather than
the other way around.
The initial goal was to allow defining an `enable_if` in the types header
and using it in the math header. But I also think this operations to types
dependency is more natural anyway.
This required changing the includes some files used from the type
header to the math implementation header. I took that change a bit
further removing the C vector math header from the C++ header;
I think that helps to make the transition between the two systems
clearer.

This commit renames `mesh_validate.cc` to `mesh_calc_edges.cc`.
I would like to move `mesh_validate.c` to C++, but it makes sense to
keep this specific algorithm in a smaller file.
This adds a new sculpt mode to the experimental new curves object.
Currently, this mode can only be entered and exited, nothing else.
The main initial purpose of this node will be to use it for hair grooming.
The patch also adds the `editors/curves/` directory for the new curves
object, which will be necessary for many other things as well.
I added a completely new mode (`OB_MODE_SCULPT_CURVES`), because
`OB_MODE_SCULPT` seems to be rather specific to meshes, and reusing
it doesn't seem worth the trouble. The tools/brushes used in mesh vs.
curves sculpt mode are quite distinct as well.
I had to add DNA_userdef_enums.h to make the patch compile with C++
(forward declaration of enums isn't allowed). This follows the same
pattern that we use for other enums in dna.

The root issue was caused by a mistake in modifier copy data which was
wrongly re-generating source modifier data identifier.
The c8cca88851 simply exposed a bug in code which always was there
since the modifiers session UUID was introduced.
Shows an importance of const qualifier :)
Since now we delegate the evaluation of the last subsurf modifier in the stack
to the draw code, Cycles does not get a subdivided mesh anymore. This is because
the subdivision wrapper for generating a CPU side subdivision is never created
as it is only ever created via `BKE_object_get_evaluated_mesh` which Cycles does
not call (rather, it accesses the Mesh either via `object.data()`, or via
`object.to_mesh()`).
This ensures that a subdivision wrapper is created when accessing the object data
or converting an Object to a Mesh via the RNA/Python API.

This node is a bit of a weird case, because it uses the value stored in an
output socket as an input. So when we want to determine if the Dot
changed, we also have to check if the Normal output changed.
A cleaner solution would be to refactor this by either storing the normal
on the node directly (instead of in an output socket), or by exposing it
by a separate input. This refactor should be done separately though.
Drivers make it way too easy to create dependenciy loops between IDs, so
need to use the same trick as in other dependency-following code in this
file to prevent those infinite loops.
hard to predict for sure how bad of a hierarchy root this can end up
producing, but in general cases think this should be OK.
Reduce compute effort of liboverrides resync process by only re-syncing
the parts of the override hierarchy that actually need it.
The main change compared to existing code (which was systematically resyncing
a whole override hierarchy), is that resyncing now operates over several
sub-hierarchies at once, each defined by their own 'resync root' ID.
This ensures that we do not get several new overrides for the same data inside
of the same hierarchy.
