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.

- Deduplicate code;
- Support no customdata interpolation for edges;
- Reduce number of required elements in context arrays.
With 74772c6920, the merge by distance code for meshes now supports
optional interpolation of custom data for vertices.
As this can be advantageous for performance and memory, it seems
convenient to support the same for edges (and in the future polygons
and corners).
So this commit reworks the code that finds the edge groups to match the
same used for vertices and thus deduplicating and simplifying the code.
Conveniently the `edge_ctx_map` array is no longer needed and can be
removed to save memory.
However it was necessary to create another array (which is usually
smaller) called `double_edges` (to match `double_verts`).

**Results:**
The profiling result depends on some factors such as:
- interpolate or not interpolate customdata;
- affect a large or small portion of the mesh;
The best case is when the customdata **is not** interpolated and the operation affects **large** portions of the mesh:
| Before: | After: | Factor: |
| ---------- | ---------- | ------- |
| 1256.61 ms | 1073.218 ms| -14.44% |
The worst case is when the customdata **is not** interpolated and the operation affects **small** portions of the mesh:
| Before: | After: | Factor: |
| --------- | --------- | ------- |
| 1077.50 ms| 1086.7 ms| +0.85% |

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.
Slight speed up of face topology building for blur node.
Avoid using increment and replacing by adding size.
Multi-threading for accumulating offsets. Early returns

When switching shading between material preview and solid modes, the
world reflective light could become uninitialized. The reason was that
the world was only updated when they actually changed. When switching
it might not be the case that the world changed and the world probe
wasn't uploaded to the texture.
This fix will reduce the locations where this information was stored
(removing the `do_world_update` attribute in `ReflectionProbeModule`).
It also doesn't reset the `do_render` flag during syncing, but post-
pone it to the actual drawing.

For overlapping regions, we currently offset the edge for resizing
regions a bit towards the contents. This makes sense for example in the
sidebar, where the region background is fully transparent by default,
and users expect the edge to be where the visible contents begin. This
was an issue in #104831 for two reasons:
- Although the region overlaps, we decided to make it fully opaque by
default. The offset is still applied, making the edge detection feel
broken.
- The offset would also be applied to header-like regions, where there
is not much padding between the edge and the content. So the edge to
resize the region would overlap buttons.
2 changes to address this:
- Only apply the offset if the region background is transparent-ish,
with a rather arbitrary alpha threshold.
- Do not apply the offset for header-like regions.

The "Single file with all the views" message was not extracted because
it is an enum item that was not exposed to the RNA, but only
selectable in some cases depending on the
`RNA_def_property_enum_funcs()`.
This commit changes the `RNA_def_property_enum_items()` so that this
enum item is exposed to the RNA.

Also fix some incorrect usages of `N_` macro instead of `TIP_` one
(these error messages typically need to get translated explicitely, not
only marked for extraction).
`use_ambient_occlusion` is a legacy property and not
connected to anything. The clip editor still write
to it for enabling the ambient occlusion renderpass.
This change will remove the legaccy option and
won't enable ambient occlusion pass anymore due
to visual and performance impact.

WITH_METAL_BACKEND is also defined globally.

When using many reflection probes with different subdivisions
it can happen that the reflection probe uses texture space that
is already been allocated for another probe.
The cause for that is that negative shift operations result into
undefined behavior, this was fixed previously by clamping the
number of bit shifts to perform, but ignoring to shift into the
other direction
This change also includes `ProbeLocationFinder.print_debug`
for future debugging.

Originally was noticed when adding drivers to a rigid body., but
it could potentially happen with any configuration.
The reason for the crash was that the ID which was modified was
not tagged as such.
Modifying drivers from the interface are likely tagging for updates
from the operator. This change makes it so the python function also
does tagging.
It is not really how one would design the system nowadays, but it
is how the Blender historically handles such cases. A bigger refactor
is possible to move tags to the places where modification actually
happens, but it seems to be a better idea to tackle it as a separate
project which will be considered no-functional-changes.

This PR fixes a compiler issue when using NVIDIA. It was introduced
when adding the reflection probes. NVIDIA compiler doesn't like
to access elements in a bound resource and pass it directly
as a parameter. It should first be added as a local variable.

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.
The Alembic importer can optionnaly interpolate vertex and matrix data.
To detect if two samples can be interpolated `get_weight_and_index`
needs to be called which output the interpolation weight and the indices
for the floor and ceil samples separately. Either the weight or the
indices could be used to determine if interpolation was needed.
This adds a `SampleInterpolationSettings` structure to hold the weight
and indices together so we don't need to manage multiple local
variables, and replaces `get_weight_and_index` with
`get_sample_interpolation_settings` which returns either a
`SampleInterpolationSettings` or nothing if no interpolation is
necessary.
This also modifies `AbcMeshData` to have an optional
`SampleInterpolationSettings` and removes members used for interpolation
from `CDStreamConfig`, which simplifies the latter structure as well as
the check in `read_mverts` to verify if interpolation is needed.
`get_config` also no longer needs a parameter for setting the now removed
`use_vertex_interpolation` member from `CDStreamConfig`. This was only
used for Mesh vertex interpolation despite also being set in the points
reader (which does not yet support any interpolation).
No functional changes.

* 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.
Navigation operations, like those of the trackpad, are not modal and
therefore are confirmed on each call.
To prevent the transform operations from being updated in this case,
add a fake navigation flag.
The removal of this flag is postponed to the next call.
* Use pi factor to convert between radiant flux and intensity
* Mark lights as normalized on export
* Add spot light export support
* Add treatAsPoint support for import and export
* Empirically match normalized distant light
* Fix wrong unnormalized point/sphere/disk light unit in Cycles
Overall it should be much closer now for all light types. Point and distant
light units are inconsistent between renderers, so not possible to match
everything there.

The spotlight is now treated as a sphere instead of a view-aligned disk.
The implementation remains almost identical to that of a point light,
except for the spotlight attenuation and spot blend. There is no
attenuation inside the sphere. Ref #108505
Other changes include:
## Sampling
Instead of sampling the disk area, the new implementation samples either
the cone of the visible portion on the sphere or the spread cone, based
on which cone has a smaller solid angle. This reduces noise when the
spotlight has a large radius and a small spread angle.
| Before | After |
| -- | -- |

## Texture
Spot light can now project texture using UV coordinates.

title="spot_light_texture.mp4" controls></video>
## Normalization
Previously, the normalization factor for the spotlight was \(\pi r^2\),
the area of a disk. This factor has been adjusted to \(4\pi r^2\) to
account for the surface area of a sphere. This change also affects point
light since they share the same kernel type.
## Versioning
Some pipeline uses the `Normal` socket of the Texture Coordinate node for
projection, because `ls->Ng` was set to the incoming direction at the
current shading point. Now that `ls->Ng` corresponds to the normal
direction of a point on the sphere (except when the radius is zero),
we replace these nodes with a combination of the Geometry shader node
and the Vector Transform node, which gives the same result as before.

All probes (including the world background probe) are stored in a single texture. Each probe
can be of any resolution as long as it is a power of 2 and not larger than 2048. So valid options
are (2048x2048, 1024x1024, 512x512, etc).
Each probe can be stored in their own resolution and can be set by the user.
> NOTE: Eventually we would like to add automatic resolution selection.
The probes are packed in an 2d texture array with the dimension of 2048*2048. The number of
layers depends on the actual needed layers. If more layers are needed the texture will be recreated.
This can happen when a new reflection probe is added, or an existing reflection probe is made visible
to the scene or its resolution is changed.
### Octahedral mapping
Probes are rendered into a cubemap. To reduce memory needs and improve sampling performance the cubemap
is stored in octahedral mapping space. This is done in `eevee_reflection_probe_remap_comp.glsl`.
The regular octahedral mapping has been extended to fix leakages at the edges of the texture
and to be able to be used on an atlas texture and by sampling the texture once.
To reduce sampling cost and improve the quality we add an border around the
octahedral map and extend the octahedral coordinates. This also allows us to
generate lower resolution mipmaps of the atlas texture using 2x2 box filtering
from a higher resolution.
### Subdivisions and areas
Probes data are stored besides the texture. The data is used to find out where the probe is stored
in the texture. It is also used to find free space to store new probes.
This approach ensures that we can be flexible at storing probes with different
resolutions on the same layer. Lets see an example how that works
Code-wise this is implemented by `ProbeLocationFinder`. ProbeLocationFinder can view a texture in a
given subdivision level and mark areas that are covered by probes. When finding a free spot it returns
the first empty area.
**Notes**
* Currently the cubemap is rendered with a fixed resolution and mipmaps are generated in order to
increase the quality of the atlas. Eventually we should use dynamic resolution and no mipmaps.
This will be done as part of the light probe baking change.

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 off from [#106952: Animation: Butterworth Smoothing filter](https://projects.blender.org/blender/blender/pulls/106952)
This patch allows the slider to take a different string than just "%",
the use case is on #106952 where we want to display "Hz" instead.
Additionally the slider got the ability to set modes, which determine
how the factor number is displayed.
`SLIDER_MODE_PERCENT` means it will multiply by 100 and display as whole numbers
`SLIDER_MODE_FLOAT` means it will display just floats with one digit after the comma
Additionally to that, because the slider range is now arbitrary and potentially deals with
large numbers, the mouse distance needed to travel from min to max has been normalized
to the range.
