Use of node group assets relies on a few properties written to asset
meta-data for proper filtering of assets in menus (add modifier menu,
node add menu, 3D view menus for tools). Currently these meta-data
properties are written when updating their source properties and when
saving the file. That means they *aren't* written when marking a group
as an asset, which is necessary because the meta-data doesn't exist
before when the group isn't an asset. Currently users have to save the
file to update menus in this case, which isn't intuitive.
As a fix, call the function to write the meta-data when marking a
data-block as an asset.

Previously, BKE level preview image code was in `BKE_icons.h` and `icons.hh`.
While these types are related, I always found this quite hard to navigate since
preview image stuff was just in the middle of icon functions. Plus, people
don't expect preview image functions in icon files, the relationship is not
obvious.
Instead, use focused files that make it easy to quickly navigate them
and see what they are dealing with.

The situation at this stage of readfile process is now sane enough, that
the regular Pose freeing code can be called, avoiding potential
memleaks.
Note that this whole 'non-Empty object with NULL obdata' case should now
be very hypothetical, since in case a linked obdata goes missing,
Blender will generate and empty place-holder for it at read time.
Tested by artificially setting all Armature objects' obdata pointer to
null in read_data code, and loading some complex production files from
Pets Project.
The `lib_link` callback cannot always be fully replaced/removed, as in
some case it is also doing some validation checks, or data editing based
on the result of lib_linking internal ID pointers.
The callback has been renamed for that purpose, from `read_lib` to
`read_after_liblink`. It is now called after all ID pointers have been
fully lib-linked for the current ID, but still before the call to
`do_versions_after_linking`.
This change should not have any behavioral effect. Although in theory
the side-effect of this commit (to split lib linking itself, and the
validation/further processing code) into two completely separated steps
could have some effects, in practice none are expected, and tests did
not show any changes in behavior either..
Part of implementing #105134: Removal of readfile's lib_link & expand code.
The `expand` callback is 'trivial' to replace, since it is only iterating
over ID pointers and calling a callback.
The only change in behavior here is that some pointers that were not
processed previously will now be.
In practice this is not expected to have any real effect (usually
the IDs used by these pointers would have been expanded through other
usages anyway). But it may solve a few corner cases, undocumented issues
though.
Part of implementing #105134: Removal of readfile's lib_link & expand code.
This commit adds a new option flag to the lib_query foreach_id code,
which will make deprecated ID pointers to be processed as well.
NOTE: Currently there is no report to the callbakcs about the fact that
it is processing a deprecated ID. This can be easily added later if it
becomes necessary.
Part of implementing #105134: Removal of readfile's lib_link & expand code.
The only acceptable case to handle internal data in 'lib_link' code is
when it depends on other IDs info. Otherwise, it should be done in
'read_data' code (and versioning if relevant).
There is no reason to do that in the 'lib_link' stage of blendfile
reading, whether the owner ID is linked or local is already known info
at the 'read_data' stage of the process. And it is more logical to do
that in code affecting internal private data of an ID, rather than in
code handling updates of it ID pointers.
Note that the camera's baground image case was already handled in the
'read_data' stage.
No behavioral change expected here.
There is no reason at all for each ID read/write callbacks to have to
deal with this generic, common data explicitely. Generic ID read/write
code is the place to handle such data (just like asset, liboverride,
etc. data are handled already).
Note behavioral change expected here.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
Remove the "_for_read" suffix from methods to get geometry and geometry
components. That should be considered the default, so the suffix just
adds unnecessary text. This is consistent with the attribute API and
various implicit sharing data access methods.
Use "from_mesh" instead of "create_with_mesh". This is consistent with
the recently used naming for the `IndexMask` API.

This commit adds modifier support for Grease Pencil 3.
The `BKE_grease_pencil_data_update` function evaluates the modifiers by
first creating a `GeometrySet` from the grease pencil data,
then evaluating the modifiers, and finally reading the
resulting `GreasePencilComponent` component and assigning
the evaluated object data.

Implements the rest of #101689, after 5e9ea9243b.
- `vdata` -> `vert_data`
- `edata` -> `edge_data`
- `pdata` -> `face_data`
- `ldata` -> `loop_data`
A deeper rename of `loop` to `corner` will be proposed as a next
step, and renaming `totvert` and `totedge` can be done separately.

Split much of BKE_pbvh.h into BKE_pbvh_api.hh.
BKE_pbvh.h is included by BKE_paint.h, which in
turn is included by large amounts of code including
RNA.
This makes it extremely difficult to change
or clean up the PBVH API, since each modification
of BKE_pbvh.h can take 20-30 minutes to compile,
even on a quad-core system with an SSD. This
commit fixes that by moving most of BKE_pbvh.h
into another file and just having the core,
external-facing interfaces in BKE_pbvh.h.
Renames `OB_MODE_EDIT_GPENCIL`, `OB_MODE_PAINT_GPENCIL`, `OB_MODE_SCULPT_GPENCIL`, `OB_MODE_WEIGHT_GPENCIL`, `OB_MODE_VERTEX_GPENCIL, and the context modes` to `*_LEGACY`.

Similar to 5f16e24cc9, this adds support for edit mode
to the point cloud object type, which is currently hidden behind an
experimental option. No interaction is possible yet, for now this
can be used as a testing for a node-group-operator-only mode.
It was assumed destination buffers were at least 1024 bytes which could
overflow by 256 bytes for sequencer directories. Resolve by passing the
destination buffer size to BKE_bpath_foreach_path_fixed_process.
Also remove strcpy use in foreach_path_clean_cb.
More consistently return geometry bounds with the `Bounds` type that
holds the min and max in one variable. This simplifies some code and
reduces the need to initialize separate min and max variables first.
Meshes now use the same `bounds_min_max()` function as curves and
point clouds, though the wrapper mesh isn't affected yet.
The motivation is to make some of the changes for #96968 simpler.
Move `GeometrySet` and `GeometryComponent` and subclasses
to the `blender::bke` namespace. This wasn't done earlier since
these were one of the first C++ classes used throughout Blender,
but now it is common.
Also remove the now-unnecessary C-header, since all users of
the geometry set header are now in C++.

Face maps were added as a prototype of a new rigging solution during
2.8 development. Their storage is redundant with the newer generic
attribute system (specifically with integer face attributes), and
they were never used much. This commit removes the face map list
and converts the storage to an attribute with the name `face_maps`.
There is nowhere to store the face map names anymore, so those
are not kept.
It probably still makes sense to have a feature like mesh face gizmo
selection for rigging. But the design and implementation woulds likely
have to change significantly, including possibly changing the storage
type, and making use of the generic attribute system instead of a
special type.
See #105317 for more discussion.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

Adds the initial stage for the grease pencil 3.0 project.
This patch includes:
* New ID and new object type.
* New DNA structures.
* New drawing engine for grease pencil (gpencil-next).
* Tests for the new grease pencil data-type.
* A few operators for conversion, switching modes and (simple) drawing.
Exposed to the user:
* An experimental option to switch to the new grease pencil.
* This will switch the grease pencil render engine to gpencil-next which can only render the new object type.
Current grease pencil objects will no longer render.
* Changing this option currently requires a restart of blender (for the keymap to update).
* A conversion setting in the `Object` > `Convert To` operator.
* A drawing operator in `Draw Mode`.

Covers the macro ARRAY_SIZE() and STRNCPY.
The problem this change is aimed to solve it to provide cross-platform
compiler-independent safe way pf ensuring that the functions are used
correctly.
The type safety was only ensured for GCC and only for C. The C++
language and Clang compiler would not have detected issues of passing
bare pointer to neither of those macros.
Now the STRNCPY() will only accept a bounded array as the destination
argument, on any compiler.
The ARRAY_SIZE as well, but there are a bit more complications to it
in terms of transparency of the change.
In one place the ARRAY_SIZE was used on float3 type. This worked in the
old code because the type implements subscript operator, and the type
consists of 3 floats. One would argue this is somewhat hidden/implicit
behavior, which better be avoided. So an in-lined value of 3 is used now
there.
Another place is the ARRAY_SIZE used to define a bounded array of the
size which matches bounded array which is a member of a struct. While
the ARRAY_SIZE provides proper size in this case, the compiler does not
believe that the value is known at compile time and errors out with a
message that construction of variable-size arrays is not supported.
Solved by converting the field to std::array<> and adding dedicated
utility to get size of std::array at compile time. There might be a
better way of achieving the same result, or maybe the approach is
fine and just need to find a better place for such utility.
Surely, more macro from the BLI_string.h can be covered with the C++
inlined functions, but need to start somewhere.
There are also quite some changes to ensure the C linkage is not
enforced by code which includes the headers.

The usage of the lib pointer was cryptic to say the least, it was
essentialy used to allow or not local IDs results in the mapping
old_id_pointer -> new_id_pointer lookup result.
Now:
- Explicitely pass a boolean to allow or not local ID as result in
lower-level code.
- Pass the 'self ID' pointer instead of its library to the whole
liblinking code (that was already the case in a few places).
Note that naming of the 'self id' pointer is currently very inconsistent
throughout the readfile liblink code, this will have to be cleaned up in
a separate step later. For now, `self_id` has been chosen for new code
as it matches the terminology in lib_query code.
The later change can also allow finer handling of lookup on undo, based
on how it was re-read (or not), should the need for this arise.
