9c0c9789cc I18n: fix Vector Math and Mix node sockets search
When searching for a new node by dragging from a socket, some results
were untranslated. This is because they did not use a translation
context matching other occurrences, from which the strings were
extracted to the translation files.

Three nodes using operations were affected: Mix and Vector Math.
- Vector Math used the default context when it should have used
  NodeTree.
- Mix and Mix RGB used NodeTree when they should have used the default
  context.

38813a7441 Nodes: unify static and dynamic declarations
This helps solving the problem encountered in #113553. The problem is that we
currently can't support link-drag-search for nodes which have a dynamic declaration.

With this patch, there is only a single `declare` function per node type, instead of
the separate `declare` and `declare_dynamic` functions. The new `declare` function
has access to the node and tree. However, both are allowed to be null. The final
node declaration has a flag for whether it depends on the node context or not.

Nodes that previously had a dynamic declaration should now create as much of
the declaration as possible that does not depend on the node. This allows code
like for link-drag-search to take those sockets into account even if the other
sockets are dynamic.

For node declarations that have dynamic types (e.g. Switch node), we can also
add extra information to the static node declaration, like the identifier of the socket
with the dynamic type. This is not part of this patch though.

I can think of two main alternatives to the approach implemented here:
* Define two separate functions for dynamic nodes. One that creates the "static
  declaration" without node context, and on that creates the actual declaration with
  node context.
* Have a single declare function that generates "build instructions" for the actual
  node declaration. So instead of building the final declaration directly, one can for
  example add a socket whose type depends on a specific rna path in the node.
  The actual node declaration is then automatically generated based on the build
  instructions. This becomes quite a bit more tricky with dynamic amounts of sockets
  and introduces another indirection between declarations and what sockets the node
  actually has.

I found the approach implemented in this patch to lead to the least amount of
boilerplate (doesn't require a seperate "build instructions" data structure) and code
duplication (socket properties are still only defined in one place). At the same time,
it offers more flexibility to how nodes can be dynamic.

405ec79a0a Fix #112883: GPU compositor crops viewed image
The GPU compositor crops the viewed images to the render resolution.
While the original size and content of the input to the viewer should be
retained as is.

This patch fixes that by specializing compositors that can use composite
outputs to be able to view images of any arbitrary size. This is still
missing the translation offset of the viewer, but this shall be tackled
separately.

e592763940 Realtime Compositor: Immediately realize transformations
This patch immediately realizes the scale and rotation components of
transformations at the point of transform nodes. The translate component is
still delayed and only realized when really needed to avoid clipping.

Transformed results are always realized in an expanded domain that avoids
clipping due to rotation or scaling. The size of the transformed domain is
clipped to the GPU texture size limit for now until we have support for huge
textures, that limit is typically 16k.

A potential optimization is to join all consecutive transform and realize
operations into a single realize operation.

Fixes #112332.

f3a1dd1eb5 Nodes: move socket declaration methods to base declaration builder
The goal here is to make it easier to use the socket declaration builder
for cases where the actual socket type is not known at compile time.
For that purpose, all the methods that are not dependent on the specific
socket type are moved to the base socket declaration builder.

A nice side effect of this is reduced templated boilerplate and that more
code can be moved out of the header.

With this patch, one is now forced to put type specific method calls before
generic method calls in a chain. For example `.default_value(...).supports_field()`
instead of `supports_field().default_value(...)`. In theory, we could keep
support for both orders but that would involve a lot of additional boilerplate
code. Enforcing this order is simple enough. Note that this limitation only
applies when chaining multiple method calls. This is still possible:
```
auto &decl = b.add_input<decl::Vector>("Value");
decl.supports_field();
decl.default_value(...);
```

75c947a467 Compositor: Use RBF Interpolation in Keying Screen node
This patch changes the interpolation algorithm utilized by the Keying
Screen node to a Gaussian Radial Basis Function Interpolation. This is
proposed because the current Voronoi triangulation based interpolation
has the following properties:

- Not temporally stable since the triangulation can abruptly change as
  tracking markers change position.
- Not smooth in the mathematical sense, which is also readily visible in
  the artists sense.
- Computationally expensive due to the triangulation and naive
  rasterization algorithm.

On the other hand, the RBF interpolation method is temporally stable and
continuous, smooth and infinitely differentiable, and relatively simple
to compute assuming low number of markers, which is typically the case
for keying screen objects.

This breaks backward compatibility, but the keying screen is only used
as a secondary input for keying in typical compositor setups, so one
should expect minimal difference in outputs.

f217380128 Realtime Compositor: Use Int2 images in JFA algorithm
This patch changes the image type used in the Jump Flooding Algorithm to
be Int2 instead of Float4. That's because we used to store the distance
along with the texel location, which we no longer do, so we are left
with the 2D texel location only which can be stored in an Int2 image.

We no longer store the distance because it is not necessarily needed, it
introduces a sqrt in each of the JFA passes, and it is less precise due
to storage in 16F images. Developers should compute the distance in the
user shader instead.

This is a non-functional change, but results in less memory usage,
higher performance, and higher precision.

acb88528a5 Realtime Compositor: Implement Inpaint node
This patch implements the Inpaint node for the Realtime Compositor. The
inpainting region is filled by sampling the color of the nearest boundary pixel
if it is not further than the user supplied distance. Additionally, a lateral
blur is applied in the tangential path to the inpainting boundary to smooth out
the inpainted region.

The implementation is not identical to the existing CPU implementation due to
technical infeasibility. In particular, the CPU implementation uses a Manhattan
distance transform, while the GPU implementation uses an Euclidean one, which is
a consequence of the use of the Jump Flooding algorithm. Furthermore, the CPU
uses a serial convolution starting from the boundary outwards, while the GPU
uses a lateral Gaussian blur in the direction tangent to the boundary.

974edc5885 Cleanup: Remove unnecessary "add node search"
Now that specific menus can be searched directly (see 7f9d51853c),
there is no need to maintain separate search functionality for adding
nodes. This PR removes the add node search. In a way this brings us
closer to the `NodeItem` situation before, but the setup is more
flexible since the menus are more standard and easier to customize.

In the few ways we customized the node search items before, this gives
us the same results as before. Overall the searching is less flexible,
but I think that is just a tradeoff we have to accept for the simplicity
of searching menus. In the future menus could be made more dynamic,
with each builtin node's menu path stored on the node type, similar to
assets. That might be a nice compromise. In the meantime this code
is just dead weight.

b5c89822ac RNA: return PointerRNA from rna create functions
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.

fa34992def Cleanup: Remove unnecessary includes from C++ data structure headers
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.

726ba534fc Realtime Compositor: Support realization of transformations
This patch adds support for the realization of transformations of
operation inputs in the Realtime Compositor. Input socket declarations
can now include a preference to what sort of realization needs to
happen.

All inputs specify realization on the operation domain by default
because that is needed for the correct operation of most operations.

Nodes may choose not to be realized on the operation domain, like the
MapUV, Plane Deform, and Bokeh Blur nodes; that's because their inputs
are treated as transform-less image objects.

Nodes may chose to realize their rotation or scale, like operations that
are not rotation or scale invariant and thus need images of identity
transformations. No nodes are declared as such so far, as this is still
being considered by developers and test builds be published for testing.

This patch coincidentally also fixes #102252 by declaring the Bokeh input
of the Bokeh Blur node to need realization of rotation. Which is the only
functional change of the patch.

Fixes #102252.

9ef2310e5f Realtime Compositor: Implement Anisotropic Kuwahara
This patch implements the Anisotropic Kuwahara filter for the Realtime
compositor and replaces the existing CPU implementation with a new one to be
compatible with the GPU implementation. The implementation is based on three
papers on Anisotropic Kuwahara filtering, presented and detailed in the code.

The new implementation exposes two extra parameters that control the sharpness
and directionality of the output, giving more artistic freedom.

While the implementation is different from the existing CPU implementation, it
is a higher quality one that is also faster and conforms better to the methods
described in the papers.

Examples can be seen in the pull request description.

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/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.

An "AUTHORS" file has been added, using the chromium projects authors
file as a template.

63e2832057 Color management: Remove old name-based exceptions
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.

940558f9ac Realtime Compositor: Implement Classic Kuwahara
This patch implements the Classic Kuwahara node for the Realtime Compositor.

A naive O(radius^2) implementation is used for radii up to 5 pixels, and a
constant O(1) implementation based on summed area tables is used for higher
radii at the cost of building and storing the tables.

This is different from the CPU implementation in that it computes the variance
as the average of the variance of each of the individual channels. This is done
to avoid computing yet another SAT table for luminance. The CPU implementation
will be adapted to match this in a future commit.

The SAT implementation is based on the algorithm described in:

Nehab, Diego, et al. "GPU-efficient recursive filtering and summed-area tables."

Additionally, the Result class now allows full precision texture allocation, which
was necessary for storing the SAT tables.

7cebb61486 Cleanup: CMake: Modernize bf_dna dependencies
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.

e1b60fdb91 Remove Z Buffer from ImBuf
It was only used by OpenEXR and Iris images, and saving the Z Buffer
in those formats was disabled by default. This option comes from the
times prior to the addition of the Multilayer EXR.

It also worth noting that it was not possible to save Iris with Depth
pass from Blender as internally it is called IRIZ format and it was
not exposed. But even after exposing this format option something still
was missing as saving and loading ITIZ did not show up the Depth pass.

The reason of removal is to make it a more clear match of the ImBuf
with a render pass, and use it instead of a custom type in the render
result and render pass API. This will simplify the API and also avoid
stealing buffers and making shallow copies when showing the render
result.

For the cases when Depth is needed a Multilayer EXR is to be used,
as most likely more than just the Depth will be needed.

On a user level this change:

- Removes the "Z Buffer" option from the interface.

- It preserves existing sockets in compositor nodes, but it will
  output black image. Also changing the image data-block will
  remove the socket unless a Multilayer EXR with Depth pass image
  is selected.

- Removes "Depth" socket of the Viewer and Composite nodes.
