- Add IDP_EnsureProperties,
- Remove create_if_needed argument from IDP_GetProperties.
Split access & creation so intention reads more clearly without
looking up function arguments.
There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.

The hash tables and vector blenlib headers were pulling many more
headers than they actually need, including the C base math header,
our C string API header, and the StringRef header. All of this
potentially slows down compilation and polutes autocomplete
with unrelated information.
Also remove the `ListBase` constructor for `Vector`. It wasn't used
much, and making it easy to use `ListBase` isn't worth it for the
same reasons mentioned above.
It turns out a lot of files depended on indirect includes of
`BLI_string.h` and `BLI_listbase.h`, so those are fixed here.

Add three cached topology maps to `Mesh`, to avoid computations when
mesh data isn't changed. Choosing the right maps to cache is a bit
arbitrary, but generally we have to start somewhere. The limiting
factor is memory usage (all the new caches combined have a
comparable footprint to a UV map).
For now, the caches added are:
- Vertex to face corner
- Vertex to face
- Face corner to face
These caches are used in quite a few places already;
- Face corner normal calculation
- UV value merging
- Setting sharp edges from face angles
- Data transfer modifier
- Voxel remesh attribute remapping
- Sculpt mode painting
- Sculpt mode normal calculation
- Vertex paint mode
- Split edges geometry node
- Mesh topology geometry nodes
Caching topology maps means they don't have to be rebuilt every time
they're used. Meshes copied but without topology changes can share
the cache, further reducing re-computations. For example, FPS with a
large mesh using the "Corners of Vertex" node went from 1.8 to 2.3.
Entering sculpt mode is slightly faster too.
There is some obvious work for future commits:
- Use caches in attribute domain interpolation
- More multithreading of second phase of map building
- Update/build caches eagerly in some geometry nodes

A small new feature that clears the mask completely on the current mesh island.
Closes#104022
When hovering outside the object the Expand operator is running on, it will get floodfilled with the mask/face set.
Previously, when the Invert option was used, it wouldn't also clear the mask/face set when hovering outside the object.

Since the normals are stored in a shared cache, tagging them dirty
recreated the cache from scratch when it was shared. Instead,
add a function that updates the cache in the same call as tagging
it dirty. This keeps the old state of the cache around even if it was
shared, and reflects the way that it's really the PBVH and sculpt
mode managing the dirty status of normals while sculpt mode
is active.
One consequence is that the BVH cache and the triangulation
cache need to be tagged dirty manually. I'd like to avoid abstracting
this more than necessary, because I'm hoping in the long term
different caching abstractions like a more global cache that takes
implicit sharing versions into account will make this complexity
unnecessary.

The `EdgeHash` and `EdgeSet` data structures are designed specifically
as a hash of an order agnostic pair of integers. This specialization can
be achieved much more easily with the templated C++ data structures,
which gives improved performance, readability, and type safety.
This PR removes the older data structures and replaces their use with
`Map`, `Set`, or `VectorSet` depending on the situation. The changes
are mostly straightforward, but there are a few places where the old
API made the goals of the code confusing.
The last time these removed data structures were significantly changed,
they were already moving closer to the implementation of the newer
C++ data structures (aa63a87d37).

This affected sculpt, vertex- and weightpaint.
So attempting to (temporarily) switching to the smooth/blur tools from
another tool using the "Shift" shortcut can fail if the corresponding
smooth/blur brush is not found/missing [which was the case in the report
because the brush was deleted].
In this case, brushes dont really get switched, but blender would still
try to cache the size (because the smooth/blur brush temporarily uses
the same size as the previous brush) of the smooth brush in
`StrokeCache` (see `smooth_brush_toggle_on`). Then in
`smooth_brush_toggle_off` it was assumed brushes were actually switched
and the (non-existing) size of the (missing) smooth brush was applied to
the **actual** brush.
Now restructure code a bit so in the case of a missing brush we can
early out (without affecting the **actual** brush then).

Keeping a mutable reference to vertex normals for the entire lifetime
of the PBVH structure makes caching the normals and sharing the cache
harder than it should be. Generally code is safer when we reduce the
number of mutable references to data.
Currently the normals are modified in two places. First is the sculpt
mesh normal recalculation. There we can just retrieve the normals from
the mesh each time. Second is the restore from an undo step. That is
unnecessary because the normals are marked for recalculation anyway.
It doesn't even make much sense to store the normals in an undo step
when we can easily recalculate them based on new positions.
This change helps with #110479. These were also the last place that
kept a mutable reference to normals. I tested undo and redo after
sculpting, and it works well for each PBVH type.
Pull Request: https://projects.blender.org/blender/blender/pulls/111470
Though this means a few loops are duplicated, overall the code is
easier to reason about because the cases are separated more. This
makes potential changes to the way normals are stored clearer
(related to !110479), and makes potential optimizations easier too.
The operator handled faces visibility change correctly but not
multires. Use the existing PBVH API function for that, also remove
a redundant call to the function that fetched the attribute pointers
again after the change.
This patch refactors most of the code of the hard eraser, both for readability purpose, and to prepare the integration of the soft mode of the eraser.
The refactoring includes :
- the use of specific structures and enum types `SegmentCircleIntersection`, `PointCircleSide`, and `PointTransferData` to handle the data more easily,
- improve readability of the intersections functions (better naming, and more accurate and generic comments),
- definition of a more generic `compute_topology_change` function that handles point insertion, removal, and curve splitting for curves geometry.

This change is a partial revert of the change.
The SCULPT_cube_tip_init() does not deal with the symmetry passes.
Additionally, the commit changed the way how the Z component of
the matrix was constructed: displaced vs. non-displaced area
coordinate.
While the code duplication is often to be avoided, sometimes it is
more clear than a centralized place with a lot of arguments passed
to a function. We can have a pass of de-duplication later on, and
make a better decision, but for now restore user level behavior to
what it is expected to be.

Call functions directly in lambdas rather than passing their
arguments in a separate void * argument. This can be changed
more in the future to move callback arguments out of smaller
structs.
The stroke mode of the eraser only tests distance with segments of the strokes, so it does not take into account strokes that only have one point, and thus no segment. This patch fixes the issue by testing if the point is inside the eraser in the case of a one-point stroke.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:

- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors

With the end goal of simplifying ownership and memory management,

`OperatorType.get_name` callback is supposed to return strings directly
usable in the UI, i.e. translated if needed.
Several callbacks did not, noticiably the generic
`ED_select_pick_get_name` and `ED_select_circle_get_name` ones.
And the `sculpt_color_filter_get_name` was not using available RNA
helpers for enum items has it should have.
Finally, `RNA_property_enum_name_gettexted` and
`RNA_property_enum_item_from_value_gettexted` were also not using the

It is a common practice in gamedev to rely on coding various data into
the alpha channel of the mesh and there was no way to preserve that when

and when that is disabled, existing alpha is locked.

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.

The hard eraser tool was not working properly when trying to erase closely to existing points, leading either to the insertion of various close points in the stroke, or to deleting a whole stroke segment.
This was due to the differenciation between the computation of the intersections between the eraser and the stroke, and the computation of whether a point lie inside the eraser, which lead to inconsistencies in the interpretation of the result.
This patch solves this issue by :
* computing if the point is inside the eraser based on the result of the intersection, to avoid unconsistencies,
* computing with integers and not float (we are in screen space anyways),
* adding the ability for source points to be cuts, and not only the inner intersections.

Face set code modifies visibility of faces, then flushes those changes
to vertex and edge visibility. However, then it did an extra flush back
from vertices to faces and edges, which shouldn't be necessary.
Historically, the OCIO based color management implementation in Blender
had exceptions to treat specific configurations differently. It was a
compatibility with the legacy "No color management" option.
With time and more development in the area there are better ways of
achieving this goal, if needed.
This commit removes the named-based exception, which also solves confusion
about why certain similar configurations (from OCIO stand point) give
different results. As well as allows to create a cleaner plate for an
upcoming additions in the OCIO configuration such as AgX.
Quite simple and technical change which constant-folds the check for
whether the scene color management enabled or not with "true" value.

This change is needed for PAINT_OT_weight_sample_group to be accessed

group. New function `BKE_object_defgroup_active_is_locked`

Implements part of #101689.
The "poly" name was chosen to distinguish the `MLoop` + `MPoly`
combination from the `MFace` struct it replaced. Those two structures
persisted together for a long time, but nowadays `MPoly` is gone, and
`MFace` is only used in some legacy code like the particle system.
To avoid unnecessarily using a different term, increase consistency
with the UI and with BMesh, and generally make code a bit easier to
read, this commit replaces the `poly` term with `poly`. Most variables
that use the term are renamed too. `Mesh.totface` and `Mesh.fdata` now
have a `_legacy` suffix to reduce confusion. In a next step, `pdata`
can be renamed to `face_data` as well.

It is possible to organize shape keys into a tree through the
reference key setting. Mesh editing and sculpting a reference
key is supposed to update all its children, but this was only
done for one level of dependencies.
This changes the code to retrieve the complete set of dependent
keys and update them all.
The paint code doesn't invoke `stroke->redraw`
on `INBETWEEN_MOUSEMOVE` events. This causes
drawing lag on devices that tends to generate
more of them, like pen tablets.
The code no longer does this. It does still exclude
inbetween events for updating the paint cursor.
I checked, and only the two paint modes (3d texture paint and image paint) actually
use `stroke->redraw`. Both are implemented to only draw when necessary:
* `paint_2d_redraw` checks for `.need_redraw` flag on tiles.
* `paint_proj_redraw` checks `ProjStrokeHandle.need_redraw`.

Many high-level functions with unrelated code were templated based on
the color attribute domain and type. In the end, those were just a few
branches though, similar to other branches. So to reduce binary bloat
and clarify code, move tempates to the point where separate types are
actually needed. Also move constant code out of loops, and use generic
arrays and spans to store some caches. The binary ended up 53 KB
smaller for me, which isn't much but it's in the right direction.
Performance wise nothing really changes. The vast majority of time in
vertex paint is spent on unrelated things like calculating normals or
uploading GPU buffers anyway.
The one ugly part I didn't account for when I started is the casting
between the "ColorGeometry" and "ColorPaint" types. I'm not sure that
this is correct, but it's just a more explicit version of what was
there already.

There's quite a few libraries that depend on dna_type_offsets.h
but had gotten to it by just adding the folder that contains it to
their includes INC section without declaring a dependency to
bf_dna in the LIB section.
which occasionally lead to the lib building before bf_dna and the
header being missing, while this generally gets fixed in CMake by
adding bf_dna to the LIB section of the lib, however until last
week all libraries in the LIB section were linked as INTERFACE so
adding it in there did not resolve the build issue.
To make things still build, we sprinkled add_dependencies wherever
we needed it to force a build order.
This diff :
Declares public include folders for the bf_dna target so there's
no more fudging the INC section required to get to them.
Removes all dna related paths from the INC section for all
libraries.
Adds an alias target bf:dna to signify it has been updated to
modern cmake
Declares a dependency on bf::dna for all libraries that require it
Removes (almost) all calls to add_dependencies for bf_dna
Future work:
Because of the manual dependency management that was done, there is
now some "clutter" with libs depending on bf_dna that realistically
don't. Example bf_intern_opencolorio itself has no dependency on
bf_dna at all, doesn't need it, doesn't use it. However the
dna include folder had been added to it in the past since bf_blenlib
uses dna headers in some of its public headers and
bf_intern_opencolorio does use those blenlib headers.
Given bf_blenlib now correctly declares the dependency on bf_dna
as public bf_intern_opencolorio will get the dna header directory
automatically from CMake, hence some cleanup could be done for
bf_intern_opencolorio
Because 99% of the changes in this diff have been automated, this diff
does not seek to address these issues as there is no easy way to
determine why a certain dependency is in place. A developer will have
to make a pass a this at some later point in time. As I'd rather not
mix automated and manual labour.
There are a few libraries that could not be automatically processed
(ie bf_blendthumb) that also will need this manual look-over.

Clay strips was using it's own brush local matrix,
which wasn't quite compatible with texture matrices.
This could lead to brush textures not lining up with
the stroke dabs.
There was also a bug where the stroke was starting
20 pixels into the stroke, which is much higher than
necassary to derive the initial rake angle.
Notes:
* The clay strips brush now uses SCULPT_cube_tip_init
to calculate the local brush matrix.
* SCULPT_cube_tip_init now accepts custom brush location
and radius arguments.
* The mouse sample preroll used to calculate initial brush
rotation angle is now smaller than the update interval.
* Clay strips now supports tip_scale_x, which has also
been added to DNA defaults.
The file is easier to read and change when less context is needed at
each step. Also extract some complex-looking flag testing into a
separate function, and move some constant checks out of loops.
* Renamed BKE_pbvh_raycast_project_ray_root to
BKE_pbvh_clip_ray_ortho for greater
clarity.
* BKE_pbvh_clip_ray_ortho no longer strictly clips
within the input ray interval. This is not necassary
for orthographic views and was too prone to floating
point error. The function is only called to clip
brush rays for orthographic views so this is acceptable.
This introduces an alias target `bf::intern::atomic` for
`bf_intern_atomic`. This has the following benefits:
- Any target name with `::` in it will be recognized as an actual
target by cmake, rather than a library name it may not know about.
and will be validated by cmake to exist. Which means if you make
a typo in the LIB section, CMake will error out telling you it
doesn't know about this specific target rather than passing it on
to the build system, where you'll either get build or linker errors
because of said typo.
- Given there is quite a cleanup still to do in the build system,
it won't always be obvious which targets have been updated to
modern targets and which still need to be done. Having a namespaced
target name is a good indicator there.

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

of BKE_pbvh.h can take 20-30 minutes to compile,

Replace `typedef struct X {} X;` with `struct X {};`
In some cases the first and last name didn't match although this
is rarely useful, even a typo in some cases, e.g. TrachPathPoint.
The new drawing operator uses the `paint_stroke` API which didn't
know about grease pencil yet. This simple change causes the redraw
to happen on every(?) event, which did not happen before.
This moves the `stroke_cache` that was previously stored on every
drawing to the `GreasePencilRuntime` struct.
Since this cache is only used for when a user is drawing a stroke, there
can only ever be one. It makes more sense to have this cache on the
data-block runtime data, rather than every drawings runtime data.
Before this change the ImBuf struct had dedicated fields for the
buffer data. Now the color space is stored inside of the struct
which wraps around the buffer information.
This only changes the field placement, without changing the way
it is handled. In the future one might imagine that operations
like stealing buffer data should null-ify the buffer colorspace
pointer. Such changes would need to have more accurate thinking
before implementation.
Should be no functional changes.
