After the replacement of auto smooth with a modifier, sharp edges are
always used, so the "shade smooth", "shade flat", and "smooth by angle"
operators cleared the attribute. However, often users spend significant
time manually tagging edges sharp, and the operators make it too easy to
lose that data.
To keep the old behavior by default, add an option called "Keep Sharp
Edges". Though this can make the operators "ineffective" at their goal
of changing the way the meshes look, or result in redundant data stored
on the mesh, it's a much safer default, especially as users get used to
the new workflow.

In particular, while Object (un)linking was already tagged in relevant
BKE code, collection (un)linking was not in several cases.
This was (partially) done by user code, though almost never for the
whole hierarchy of parents.
Technically, the tag is done as part of
`collection_object_cache_free_parent_recursive`/`collection_object_cache_free`,
since currently clearing this cache is done everytime to collection
hierarchy or their content is modified.
It also removes `collection_tag_update_parent_recursive`, which was
already doing something similar, but was only called from code
adding/removing objects to collections, and was walking the same parent
hierarchy as `collection_object_cache_free_parent_recursive`.
This commit implements the decision made in #116601, to tag modified
data as close as possible from the code modifying it.
---------------------
This has an impact on deg tagging, which takes over twice as much cycles
with this commit compared to previous code when opening a Pets production
file with several liboverrides (`deggraph_id_tag_update_single_flag` goes
from less than 0.03% to over 0.06%).
The overhead remains extremely low though, and is totally unmeasurable in
global execution timing. Timing of the liboverride processing on opening
the production file also did not show any measurable differences.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

The issues was a missing depsgraph tag after adding the hook modifier.
Because of this, the depsgraph did not make a new copy of the object,
which led to a discrepancy between the number of modifiers on the original
and evaluated object.
Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Some common headers were including this. Separating the includes
will ideally lead to better conceptual separation between CustomData
and the attribute API too. Mostly the change is adding the file to
places where it was included indirectly before. But some code is
shuffled around to hopefully better places as well.
Except for vertex groups and a few older color types, these
are generally replaced by newer generic attribute types.
Also remove some includes of DNA_mesh_types.h, since it's
included indirectly by BKE_mesh.hh currently.
Each value is now out of the global namespace, so they can be shorter
and easier to read. Most of this commit just adds the necessary casting
and namespace specification. `enum class` can be forward declared since
it has a specified size. We will make use of that in the next commit.
Use the standard "elements_num" naming, and use the "corner" name rather
than the old "loop" name: `verts_num`, `edges_num`, and `corners_num`.
This matches the existing `faces_num` field which was already renamed.
Pull Request: https://projects.blender.org/blender/blender/pulls/116350
Make the naming consistent with the recent change from "loop" to
"corner". Avoid the need for a special type for these triangles by
conveying the semantics in the naming instead.
- `looptris` -> `corner_tris`
- `lt` -> `tri` (or `corner_tri` when there is less context)
- `looptri_index` -> `tri_index` (or `corner_tri_index`)
- `lt->tri[0]` -> `tri[0]`
- `Span<MLoopTri>` -> `Span<int3>`
- `looptri_faces` -> `tri_faces` (or `corner_tri_faces`)
If we followed the naming pattern of "corner_verts" and "edge_verts"
exactly, we'd probably use "tri_corners" instead. But that sounds much
worse and less intuitive to me.
I've found that by using standard vector types for this sort of data,
the commonalities with other areas become much clearer, and code ends
up being naturally more data oriented. Besides that, the consistency
is nice, and we get to mostly remove use of `DNA_meshdata_types.h`.

This adds a new `Bake` node which allows saving and loading intermediate geometries.
Typical use cases we want address with this currently are:
* Bake some data for use with a render engine.
* Bake parts of the node tree explicitly for better performance.
For now, the format that is written to disk is not considered to be an import/export format.
It's not guaranteed that data written with one Blender version can be read by another
Blender version. For that it's better to use proper interchange formats. Better support for
those will be added eventually as well. We also plan an `Import Bake` node that allows
reading the blender-specific baked data independent of the Bake node and at different frames.
The baking works very similar to the baking in the simulation zone (UI and implementation
wise). Major differences are:
* The Bake node has a `Bake Still` and `Bake Animation` mode.
* The Bake node doesn't do automatic caching.
Implementation details:
* Refactored how we create the Python operators for moving socket items so that it also
makes sense for non-zones.
* The `ModifierCache` stores an independent map of `SimulationNodeCache` and
`BakeNodeCache`, but both share a common data structure for the actually baked data.
* For baking, the `Bake` node is added as a side-effect-node in the modifier. This will make
sure that the node is baked even if it's currently not connected to the output.
* Had to add a new `DEG_id_tag_update_for_side_effect_request` function that is used
during baking. It's necessary because I want to evaluate the object again even though none
of its inputs changed. The reevaluation is necessary to create the baked data. Using
`DEG_id_tag_update` technically works as well, but has the problem that it also uses the
`DEG_UPDATE_SOURCE_USER_EDIT` flag which (rightly) invalidates simulation caches
which shouldn't happen here.
* Slightly refactored the timeline drawing so that it can also show the baked ranges of
Bake nodes. It does not show anything for baked nodes with a in Still mode though.
* The bake operator is refactored to bake a list of `NodeBakeRequest` which makes the
code easier to follow compared to the previous nested
`ObjectBakeData > ModifierBakeData > NodeBakeData` data structure.
* The bake operators are disabled when the .blend file is not yet saved. This is technically
only necessary when the bake path depends on the .blend file path but seems ok to force
the user anyway (otherwise the bake path may be lost as well if it's set explicitly).
* The same operators are used to bake and delete single bakes in `Bake` nodes and
`Simulation Zones`. On top of that, there are separate operators of baking and deleting all
simulation bakes (those ignore bake nodes).
* The `Bake` node remembers which inputs have been fields and thus may be baked as attributes.
For that it uses an `Is Attribute` flag on the socket item. This is needed because the baked data
may still contain attribute data, even if the inputs to the bake node are disconnected.
* Similar to simulation zones, the behavior of `Bake` nodes is passed into the geometry nodes
evaluation from the outside (from the modifier only currently). This is done by providing the
new `GeoNodesBakeParams` in `GeoNodesCallData` when executing geometry nodes.
Next Steps (mostly because they also involve simulations):
* Visualize nodes that have not been evaluated in the last evaluation.
* Fix issue with seemingly loosing baked data after undo.
* Improve error handling when baked data is not found.
* Show bake node in link drag search.
* Higher level tools for managing bakes.

No functional changes.
Move the function ED_id_action_ensure to animrig,
and rename it to `id_action_ensure`.
This is in order to reduce references from animrig
to the editor code.

The term `looptri` was used ambiguously for both single & arrays.
The term `tri` was also used, causing `tri->tri`.
Use terms:
- `looptris` for an array or when dealing with multiple items.
- `looptri` is used when dealing with a single item.
- `lt` for a single MLoopTri variables & arguments.
This was already a convention but not followed closely.
"mesh" reads much better than "me" since "me" is a different word.
There's no reason to avoid using two more characters here. Replacing
all of these at once is better than encountering it repeatedly and
doing the same change bit by bit.
Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

Move the contents of `ANIM_bone_collections.h` into its C++
`ANIM_bone_collections.hh` sibling. Blender is C++ by now that we can do
without the C header.
No functional changes.
Inlining the functions is simpler nowadays, since there are utility
functions to copy spans and tag the mesh caches dirty. Also use an
array instead of a raw pointer for multires.
Resolves#103789
Implement the next phases of bounds improvement design #96968.
Mainly the following changes:
Don't use `Object.runtime.bb` for performance caching volume bounds.
This is redundant with the cache in most geometry data-block types.
Instead, this becomes `Object.runtime.bounds_eval`, and is only used
where it's actually needed: syncing the bounds from the evaluated
geometry in the active depsgraph to the original object.
Remove all redundant functions to access geometry bounds with an
Object argument. These make the whole design confusing, since they
access geometry bounds at an object level.
Use `std::optional<Bounds<float3>>` to pass and store bounds instead
of an allocated `BoundBox` struct. This uses less space, avoids
small heap allocations, and generally simplifies code, since we
usually only want the min and max anyway.
After this, to avoid performance regressions, we should also cache
bounds in volumes, and maybe the legacy curve and GP data types
(though it might not be worth the effort for those legacy types).

Currently we have options to transfer the paint mask, face sets, and
color attributes to the new mesh created by voxel remesh. This doesn't
make use of the generic attribute design, where it would be clearer to
transfer all attributes with the same methods. That's reflected in the
code as well-- we do duplicate work for the mask and vertex colors, for
example.
This commit replaces the transfer options with a single checkbox for
all attributes. All attribute types on all domains are transferred with
basically the same method as the "Sample Nearest" node from geometry
nodes-- they take the value from the nearest source element of the same
domain. Face corners are handled differently than before. Instead of
retrieving the mixed value of all the corners from the nearest source
vertex, the value from the nearest corner of the nearest face.
---
Some timing information, showing that when interpolating the same
data, the attribute propagation is significantly faster than before.
Edge and corner attributes would add some cost (edges more than
corners), but might not always be present.
