Under some circumstances the `value_task` run by node tree updates
needs access to a node group topology cache. Unlike the `usage_task`
it was not ensuring the cache for the node group, so a stale cache
could be used (triggers assert).

Part of incoming refactors in interface layout c++ code, this enables
forward declaring this enum type. Enum is renamed as `EmbossType` and
moved to `blender::ui` namespace. No user visible changes expected.

This adds a new Camera Info node to Geometry Nodes. It provides information
about the passed in camera like its projection matrix and focus distance.
This can be used for camera culling which was must more complex before.
It also allows building other view-dependent effects.

The issue is caused by the fact that when both compositors are used,
`fftwf_plan_dft_r2c_2d` can end up being called in parallel, which is
only thread-safe if `fftwf_make_planner_thread_safe` is called before.
This is done by `fftw::initialize_float`, but only if the FFTW threading
support library is available. Said library was not detected correctly on
Windows because of a typo, which this change addresses. This should also
make the fog glow faster on Windows because it'll now use multithreaded
FFT as intended.
This change also moves the call to `initialize_float` to the main
function because the FFTW functions it calls are not thread-safe and
because FFTW is also used by Audaspace, which cannot call it.

The Glare node currently has a Maximum Highlights input, which has a
special value of 0.0, where the maximum is implicitly set to infinity,
that is, no suppression of highlights happen at that special value. Such
special values are hard to discover and make sliders non-continuous.
To fix this, we introduce a new panel toggle input called Suppress
Highlights, which the user can enable then control the maximum value.
This also have the advantage that the Maximum value is more clear, since
it is now under a panel more clearly named.
This is now possible since the introduction of boolean sockets and node
panel toggle inputs.

This patch makes it such that the compositor fallback to using the
order of the inputs to infer the domain priority if no domain priority
is specified. This is more robust since some nodes do not declare their
domain priorities and indirectly rely on the order of insertions in some
containers and thus might fail in the future.
We opt for this as opposed to requiting all nodes to declare their
priorities for code brevity.
This makes it possible to restore previous Blender 4.3 behavior of bump
mapping, where the large filter width was sometimes (ab)used to get a bevel
like effect on stepwise textures.
For bump from the displacement socket, filter width remains fixed at 0.1.

Resolves#136183
To avoid quadratic worst case runtime when gathering values from
the modifier properties, build a temporary VectorSet of the modifier's
IDProperties. In the file from #136183, this change improves playback
performance by 1.4x for me, from 50 to 70ms.
Ideally IDProperty groups would have constant time lookup on their
own, but that's a much larger change, and this smaller change for just
Geometry Nodes is not so invasive.

Usually we prefer to propogate attributes based on name, even for
conversion between geometry types. Builtin attributes are a common
exception though. The Curve to Points node and the Curve to Mesh node
didn't correctly handle the "custom_normal" attribute, which shouldn't
be propagated. This has only been a problem since custom normals were
converted to a generic attribute on meshes in f9b627d29c.

The Cryptomatte node fails for image sequences in some cases. This is
due to a use after free error which might even crash in some cases. This
is because the loop that computes the image Cryptomatte layers calls the
cached images container to get the passes, which might free the render
layers structure that is used while looping.
To fix this, gather the render pass names first then retrieve all the
images at once.
If a panel has a toggle, then it's a best practice that everything inside it is
grayed out of the toggle is off. It's not something we can enforce for node
groups, but should enforce it for built-in nodes. Right now, we don't have
built-in nodes with panels, but that may change e.g. with #135990.
This patch makes it so that the socket usage inferencing takes panel toggles
into account when determining if an input socket in a built-in node in a panel
is used.

The newly added Mix node causes the compositor to assert and misbehave.
That's because its has unavailable sockets, and the compositor code base
was not designed to handle unavailable sockets. To this patch fixes that
by handing unavailable sockets everywhere that matters.
This patch adds support for boolean sockets in the compositor. This
involves adding a new Bool ResultType and handling it in relevant code.
For shader operations, booleans are passes as floats since GPUMaterial
does not yet support boolean types.

Callbacks: exec invoke & modal now use a typed enum wmOperatorStatus.
This helps avoid mistakes returning incompatible booleans or other
values which don't make sense for operators to return.
It also makes it more obvious functions in the WM API are intended
to be used to calculate return values for operator callbacks.
Operator enums have been moved into DNA_windowmanager_enums.h
so this can be used in other headers without loading other includes
indirectly.
No functional changes expected.

This patch adds support for all types of single values for the File
Output node, image types are not yet supported. This involves converting
integer types to float since image saving code does not support integer
images.
This patch adds a new Image Info node which returns information about
compositor images. The node has three sources:
The node returns the following information:
- Pixel Coordinates: The coordinates of the centers of the pixels in the
image. Those are essentially the integer coordinates with half pixels
offsets added.
- Texture Coordinates: Zero centered pixel coordinates normalized along
the greater dimension. Somewhat analogous to Object coordinates in
shader nodes.
- Resolution: The resolution of the image.
- Location: The location of the image in the virtual compositing space.
- Rotation: The rotation of the image in the virtual compositing space.
- Scale: The scale of the image in the virtual compositing space.
This node is very useful to allow greater flexibility and procedural
creations. For instance, coordinates can be used to create procedural
effects like vignette using very simple math nodes. And size can be used
to compute size-relative parameters for pixel-parameter nodes.

This patch adds common nodes that are used in Geometry Nodes and Shader
Nodes to the compositor. The following new nodes were added:
- Vector Math.
- Vector Rotate.
- Vector Mix.
- Value Mix.
- Clamp.
- Float Curve.
- Blackbody.
The follow nodes were replaced by common counterparts:
- Value.
- Color Ramp.
- Mix Color.
- Map Range.
- Math.
- Combine XYZ.
- Separate XYZ.
- Vector Curves.
Some new features were gained in the process:
- Mix Color can now clamp both factor and result.
- Map Range can map different types and interpolations.
- Vector Curves gained a new Factor input.
Some behaviors were changed:
- Map Range previously forcibly clamped values whose magnitude is larger
than the arbitrary value of 10000. This is no longer the case.
Some nodes were removed:
- Map Value. This was Map Range without the maximum 10000 limitation
followed by a Clamp node. Both are now available as nodes.
Some common nodes remain separate:
- Separate/Combine Color. Shader counterpart does not yet support all
color modes, and does not support alpha.
- RGB Curves. Shader variant does not support Film-Like curves or
Black/White balancing.
Texture nodes will also be added soon in a separate patch. Nodes that
were replaced are now deprecated but still exist and will later be
removed in v5.0. Backward compatibility code was introduced to convert
from the deprecated nodes to the new nodes.

The import nodes are considered complete enough to expose without
the experimental option. This commit removes the option so they will
be exposed in 4.5. There are still some possible future improvements,
including automatic caching, possibly exposing more input sockets,
and possibly including imported paths in the "Internal Dependencies"
panel. Those are considered non blocking though.

This used custom data types before, which was misleading and didn't
scale well because the set of attribute types is different than the set
of grid types we can store. Now just use the grid data type, like how
the store named attribute node uses the attribute type.
This covers backward compatibility, but not forward compatibility.

The main reason that didn't work before because undefined custom node groups
have the undefined `bNodeType` (and thus are ignored in various places) but are
actually still groups that can be evaluated. The fix is just to handle custom
node groups a bit more explicitly.
In the future, we may want to have a separate "undefined custom group"
`bNodetype`, but that might a be a bit bigger project.

Implement shortcuts for viewer nodes. Viewer nodes are now activated using the operator `bpy.ops.node.activate_viewer()` instead of activating the viewer by setting the node to active.
This also unifies the behavior with viewer shortcuts in the compositor (see attachment in the original PR).

This patch provides const variants to the cpu_data accessors that
returns GSpan. This is done to better const correctness. Some code need
non-const data even for read-only data, so we have to const cast those
for the moment.
This patch refactors the result class to replace proxy results with the
possibility of doing data sharing through a shared heap allocated data
reference count. This is more robust and simpler since proxy results no
longer need to be handled as a special case in a lot of the results
code. Additionally, it allows stronger const correctness since inputs to
operations can now be const.
This is somewhat similar to implicit sharing used in other parts of
Blender, so we can look into using that in the future.

The main issue of 'type-less' standard C allocations is that there is no check on
allocated type possible.
This is a serious source of annoyance (and crashes) when making some
low-level structs non-trivial, as tracking down all usages of these
structs in higher-level other structs and their allocation is... really
painful.
MEM_[cm]allocN<T> templates on the other hand do check that the
given type is trivial, at build time (static assert), which makes such issue...
trivial to catch.
NOTE: New code should strive to use MEM_new (i.e. allocation and
construction) as much as possible, even for trivial PoD types.

This replaces the implicit use of the `radius` attribute on the input
curves with an input field `Scale` that gets evaluated on the point
domain of the input curves to scale the profile.
It wasn't super intuitive that the `radius` would actually act as
a scale of the profile. E.g. if the radius of the input curve was
`1 meter` the resulting profile was unscaled (scaled by 1), but
wouldn't necessarily have a size of `1 meter` (only if the profile
also had a size of 1m)! If imperial units were used, `3.28084 ft`
would correspond to a scale of 1.
This change makes this behavior a lot more clear and potentially
removes the need for the assumption that the default curve radius
is `1.0f` (Ideally, the default curve radius should be `0.01f`).
While we did consider making the `Scale` input use the `radius`
field implicitly by default, we decided against it, because it again
"hides" the dependency on the radius and the fact that the radius
is used as a scale. Letting the user make this decision seems better.

**How to reproduce:**
1. Add Cryptomatte Node
2. Enable 'Object' render passes
3. Connect Cryptomatte to output (composite or viewer node)
4. Optional: set matte ID
5. (Do not connect input image)
6. Render
7. Observe invalid output image (or assert in debug build)
(see also PR for an example blend file)
Only CPU is affected. The solution follows the behavior of the GPU backend, where the input color of the single value input image is multiplied with the matte result to produce a non constant output.

The Mix Color shader node does not retain the alpha channel of the first
input in both the Linear Light and Soft Light modes, while it is retain
for other modes. Further, result clamping also ignores the alpha due to
using the vector clamp function, which introduces implicit conversion
that removes the alpha.
This does not matter for EEVEE because it does nothing with the alpha
channel. But the code will now be shared with the compositor, which does
care about the alpha channel. So adjust the code accordingly to retain
the alpha in those cases.
