The displacement smear brush works by evaluating the previous
displacement of a given neighbor vertex to generate a weighted average.
Prior to the linked commit, the mesh-sized `prev_displacement` array
would be initialized to (0.0, 0.0, 0.0) by subtracting the
`limit_surface_co` from itself.
in certain cases, a neighbor vertex value may not be initialized,
causing NaN to get propagated through the mesh.
To fix this, and avoid needing to reintroduce this unnecessary
computation, explicitly initialize `prev_displacement` to an array of
(0.0f, 0.0f, 0.0f).

Instead of requiring an image buffer to draw a bigger preview image
while dragging, allow passing an icon ID and draw that as preview. This
is also how we draw previews elsewhere. Use this for attaching the asset
previews to draggable buttons.
A small user visible change is that previews from the asset browser will
always draw at the default size (multiplied by the interface scale)
while dragging. Previously it used the same size as the asset browser
preview size, which I don't think was useful really. With small sizes
the preview while dragging got unnecessarily small too, with big sizes
it got in the way.
Needed for #131871.
Custom preview images loaded from disk are supposed to load one by one
in a background thread, but pop up in the UI as they get ready. This
gradual/progressive loading wasn't working correctly, previews would
only show up after all current preview requests were handled. I think
there would still be some progressive loading, since handling a batch of
requests might finish before all requests for the current frame are in.
Now it works as intended, by actually tagging loaded previews.
Mistake in 16ab6111f7.
Noticed while working on #131871.
When loading preview images from disk, we'd first scale them to the
standard preview image size (in `icon_copy_rect()`) and then scale them
again to the drawing size when eventually drawing to screen. The first
scaling would happen on the CPU, which is slow, and without filtering.
Now the image is stored in its original size and only scaled when
drawing, which uses scaling on the GPU with mipmaps and bi-linear
filtering. While a bit more blurry, the resulting image has less
artifacts and represents the original image better. Keeping the images
unscaled means memory footprint is bigger, we could cap the size if
necessary.
Noticed while working on #131871. Asset shelf previews would have more
artifacts than before.

The handling of influence vertexgroups was incomplete/inconsistent.
Some prior work was already done in 08539618cd, c452d5d9e8,
782a4c9d85, 0fd3f3c216, 434f94b254, 82ea972834, f6b820ccb7,
00968fe6db .
Now that the inverting is handled consistently, we can move that part
out of specific modifier code an into the generic retrieval function
`greasepencil::get_influence_vertex_weights` -- resulting in all
modifiers using it behaving the same.
There were some modifiers already handling
`GREASE_PENCIL_INFLUENCE_INVERT_VERTEX_GROUP`, however even those still
had one issue: if no vertexgroup was set, invert would still have been
calculated (this issue is also resolved with this PR).
Remaining modifiers that were offering influence vertexgroups (e.g.
Noise) but ignoring it now work correctly.
NOTE: there are still modifiers handling influence vertexgroups outside
of `greasepencil::get_influence_vertex_weights`:
- Armature (has own code for this in
`BKE_armature_deform_coords_with_curves`)
- Shrinkwrap (has own code for this in `shrinkwrapParams_deform`)
- Thickness (this rather special behavior is untouched)

This patch delays applying transformations until realization happens on
some other domain.
Currently, transformations are applied immediately at the point of
transform nodes, this is problematic for a few reasons:
- If that result was then realized on some other domain, interpolation
will have happened two times, at the transform nodes and at the node
that required realization, causing less than ideal precision issues.
- It is not possible to repeat or extend a rotated result because its
empty areas will be zero filled, leaving gaps in its extension. So
this patch is a prerequisite for #132371 if we want full support for
repetition.
- Doing inverse transformations will introduce interpolation artifacts
which might be undesirable. Inverse transformations might be used to
do pixelation for instance, so this change will be undesirable in this
case. But we decided that this is not a use case that we want to
support, and we added explicit pixel size control to the pixelate node
as an alternative.
So this has four implications, two that might be considered bad:
- Transformations will now be higher quality and more precise.
- Repetition and other boundary extension methods will now be possible.
- Downsampling then upsampling will no longer produce pixelated results.
- Realization might happen multiple times with identical results in some
cases.
The last point not a big issue, since domain realization is not a big
bottleneck in the compositor, and the plan is to move realization into
pixel operations, so it will even be more efficient than it is now.

This changes the `ListBase` argument for certain motion path functions
to `Vector<MPathTarget *>`. (and `Span`)
To better describe what the function is doing,
`animviz_get_object_motionpaths` has been renamed
to `animviz_build_motionpath_targets`.
Since `BLI_freelistN` can no longer be used, I added
`animviz_free_motionpath_targets`.
Note that the Vector is of `MPathTarget *` which
are allocated the C way. Because the `MPathTarget` struct is defined
in the .cc file, that's the only way for it to work atm.
Other refactors may mitigate that in the future, but I wanted to keep
the scope small.

Vulkan shader compiler accesses the cache folder via multiple threads.
GHOST part isn't thread safe and can return and overwrite the returned
cache path. This resulted into crashes when performing background
rendering and failing test cases, loading of incorrect shaders etc.
This PR fixes this to cache the cache folder location in the
VKShaderCompiler, which is loaded via the main thread when the vulkan
backend is initialized.

The core issue was that the geometry batch cache (e.g. `MeshBatchCache` or
`PointCloudBatchCache`) was dependent on the object. This is problematic when
the the same geometry is used with multiple different objects because the cache
can't be consistent with all of them.
Fortunately, the only thing that was retrieved from the object was the number of
material slots, so if that can be avoided we should be fine. We can't just use
the number of material slots stored on the geometry because that may have no
material slots but still has material indices which are overridden on the object
level.
The solution is to take make the number of materials for a geometry only
dependent on the actual `material_index` attribute and not on the number of
available slots. More specifically, we find the maximal referenced material
index and handle that many materials. This number does not depend on how many
material slots there are on the object, but it still allows the object to
override materials slots that the mesh references.
A downside is that the maximum material index has to be computed which often
requires an iteration over the mesh. Fortunately, we can cache that quite easily
and the computation can be done in parallel. Also we are probably able to
eagerly update the material index in many cases when it's set instead of
computing it lazily. That is not implemented in this patch though.
The largest part of the patch is making the maximal material index easily
available on all the geometry types. Besides that, the material API is slightly
replaced and the drawing code now makes use of the updated API.

Memory areas was requested to be preferable host visible. On some
platforms this would fail to allocate. Best is to not add preferable
host visible for typically large allocations.
This PR also gives the caller the responsibility to set the allocation flags.

The issue was twofold, the `draw_tests` library was missing a link
dependency on `gpu_tests`, and the `gpu_tests` would only be generated
if `WITH_GPU_BACKEND_TESTS` or `WITH_VULKAN_BACKEND` were also ON due
to a superflous condition.

This implements all the auto masking options in sculpt mode.
* Stroke: Only affects strokes that are initially under the cursor.
* Layer: Only affect strokes in the same layer as the initial strokes under the cursor.
* Material: Only affect strokes with the same material as the initial strokes under the cursor.
* Active Layer: Only affect strokes in the active layer.
* Active Material: Only affect strokes that use the active material.
The `Active Layer` toggle in the toolbar has been moved to this panel.

This patch uses OCIO luminance for implicit conversion from color to
float in the compositor. This is done to match other node systems, and
because luminance is a much better default than the average formula used
before.
Versioning was added to retain average conversion for old files.

This would change the image type in image_save_post, which would make the
logic in BKE_image_acquire/release_renderresult mismatched.
Also consistently call BKE_image_release_renderresult when the render result
is null, rather than only doing it half the time.

This add back the NDC offset that was present in the legacy overlay.
But instead of adding a new view for it, we add `ndc_offset_factor`
to `State` to simplify wire offseting
Instead of modifying the projection matrix, we compute the unit
offset and pass it to the shader which choose the appropriate
factor to apply to the vertex position.
The value is put inside `State` so that it can be referenced
easily by multiple overlays.
Later on (once we move the global UBO inside Overlay) we can
move this to a UBO.
This only implements it for wireframe and edit mesh vert and
edges.
Note: that there seems to be some code duplication with the
edit mesh vertex code. That's to be tackled in another commit.

This adds a new `DNA_print.hh` header which contains functions to print DNA
structs with all their data members in a human readable form. This is intended
for debugging purposes.
The basic usage is very straight forward: `DNA_print_struct(TypeName, data);`.
For example: `DNA_print_struct(bNode, node);`.
There is also `DNA_print_structs_at_address` which is primarily useful when
debugging what is written to a .blend file.
This was originally developed for #133063, but is already quite useful on its
own.

Before, it was only possible to apply modifiers through a multires modifier if
they were deform-only. The Geometry Nodes modifier is of course not deform-only.
However, often one can build a node setup, that only deforms and does nothing
else.
To make it possible to apply the Geometry Nodes modifier in such cases the
following things had to be done:
* Update `BKE_modifier_deform_verts` to work with modifiers that implement
`modify_geometry_set` instead of `deform_verts`.
* Add error handling for the case when `modify_geometry_set` does more than just
deformation.
* Allow the Geometry Nodes modifier to be applied through a multi-res modifier.
Two new utility types (`ArrayState` and `MeshTopologyState`) have been
introduced to allow for efficient and accurate checking whether the topology has
been modified. In common cases, they can detect that the topology has not been
changed in constant time, but they fall back to linear time checking if it's not
immediately obvious that the topology has not been changed.
This works with the example files from #98559 and #97603.

Support thumbnail that shows the file contents instead
of the default blend file icon for all files in Finder.
Some files may still have the usual blender icon as thumbnail
depending on their contents.
blender-thumbnailer process is kept alive by the system
in the background and is invoked by QuickLook when needed.
The checkbox to disable the extension is present in
the Settings app.
It will NOT be an interactive "Preview" that allows richer
interactions like Panning viewport, or rotating 3D objects.
This makes the `material_index` attribute built-in on `CurvesGeometry` which
means that it's built-in on `Curves` and `GreasePencil`. While only Grease
Pencil can use it so far during rendering, we already depend on them on curves
when converting between curves and Grease Pencil.
Making the attribute built-in implies that it is locked to one domain and type
(`Curve` domain and `int32` type in this case).
This makes curves more consistent with meshes.

Cycles uses pixel buffers to update the display. Due to making things
work the vulkan backend downloaded the GPU allocated pixel buffer to the
CPU, Copied it to a GPU allocated staging buffer and update the display
texture using the staging buffer. Needless to say that a (CPU->)GPU->CPU->GPU
roundtrip is a bottleneck.
This PR fixes this by allowing the pixel buffer to act as a staging
buffer as well.
Viewport and final image rendering performance is now also similar.

This is due to missing depsgraph update and notifiers to redraw the
viewport region. `ensure_selection_domain` returns false when entire
domain elements are/ain't selected. This makes the `changed` boolean
false that further prevents update calls. Now fixed with bitwise
condition.
