This applies an OpenColorIO display, view and look transform on a color
in the scene_linear colorspace.
In general, OpenColorIO configurations do not contain a colorspace for
every view + display, especially if they are modern configs using the
display colorspace and shared view mechanisms. Nor do they include looks.
So the Convert Colorspace node is not sufficient.
Additionally, we would like to avoid making the colorspace list too long
in the default config, as we are adding many new views and transforms.
Exposure, gamma curves and white point functionality are not included
in this node, as there are native ways of doing that in the compositor.
These settings are marked non-editable in the Python API.

This patch turns node Menu options into menu inputs. This patch only
covers node operations like Filter, Distort, and so on. Pixel nodes like
Color Balance, Matte, and so on will be done in a separate patch.

This patch unifies the Gamma node across editors:
- Compositor now uses the Shader Gamma node implementation.
- Geometry Nodes also uses the node as a new addition.
- UI-wise in the Compositor, only socket labels change to "Color".
Forward compatibility is broken for the compositor, and the python API
changed, since the node's ID name is now ShaderNodeGamma as opposed to
CompositorNodeGamma.

This patch replaces the Composite node with the Group Output node as the
primary compositor output. The old node was removed and versioned. This
was done for consistency with Geometry Nodes and in preparation for more
generic use of the compositor in VSE modifiers, layered compositing, NPR
multi-stage compositing, and more.
The Group Output node relies on the node tree interface, so we now have
a default interface of a single input and a single output. For now, only
the first input is considered while the rest are ignored, just like the
Geometry Nodes design. Furthermore, the input is required to be of type
color. Warnings and errors are issues if any of those are not met, also
similar to Geometry Nodes.
This introduces a new limitation: Composite outputs can no longer exist
in node groups, since they obviously then act as their respective group
outputs.
A refactor for the compositor scheduler is needed to simplify the logic
after this change, but this will be done in a separate patch.

Geometry Nodes' Add > Input > Import menu includes file format items
such as "Standford PLY (.ply)", "STL (.stl)", "Text (.txt)". The
latter needs to be translated because "Text" is a generic format.
These items are declared using a custom function
`node_add_menu.add_node_type`, with a `label` argument. This commit
adds the `label` argument to the function arguments that can be
extracted from specific node declaration functions, and specifies the
argument position for each:
"add_node_type", "add_node_type_with_outputs", "add_simulation_zone",
"add_repeat_zone", "add_foreach_geometry_element_zone",
"add_closure_zone".
There is currently no facility to specify a translation context but it
could be easily added if the need arises.
Most of these functions do not actually declare new, unique messages,
but it could happen in the future. In addition, two messages were
extracted using manual `iface_()` calls, which are no longer needed
after this change.
Reported by Ye Gui in #43295.
This patch removes the Texture node from the compositor, which was based
on the legacy Internal Textures system in Blender. The main motivation
for removing this node is as follows:
- Procedural texturing nodes that previously existed in shading and
geometry nodes are now supported in the compositor, which cover 95% of
what is previously possible using and even adds new possibilities like
Gabor, Bricks, and various improvements to existing texture types.
- The old texture system did not support GPU evaluation, so it was
always computed and cached on the CPU, which causes bad performance
especially for interactive use in the viewport compositor. While the
new nodes are fully GPU accelerated and do not require any caching.
- The Texture node didn't support Texture nodes, so it was not fully
supported and we so far had a warning about that.
- The general direction in Blender is to remove the old texture system,
and the compositor was one of the last main users of it. 5.0 is thus
the ideal time to remove such use.
- The Texture node was always and still is a source of bugs, since it
relies on proper tagging for cache invalidation and updates, which is
so far not perfect. It also suffers from UI/UX issues, since it needs
to be adjusted from the properties panel, which can break if there are
other texture nodes in the context.
This is a breaking change and no versioning was attempted since:
1. It is impossible to get the same results as before due to the use of
different random number generators, so any versioning would just give us
the general look.
2. The Texture node supports a lot of possible configurations. For
instance, each general texture can have many options for the basis type,
and each basis type might have multiple options. So versioning all of
that will take a lot of time, code, and effort.

This patch removes the Dot output from the Normal node. This previously
computed negative the dot product of the normalized inputs. We are
removing it because we now have a Vector Math node that can compute the
dot product, and because it output is confusing, considering it computes
the negative of the product and it implicitly normalized the input.
The node was moved to the input category, and might be later extended to
allow normal picking from the scene or normal passes.
Fixed#132770.

It is generally expected that items within the same section in the Node
Add menu appear in alphabetical order.
However, certain handful of places in the different node editor menus
don't seem to follow this convention. This patch simply re-arranges the
items in some places to follow alphabetical order.

Previously, one had to search for the name of an input node (Geometry, Light
Path, etc.) instead of for the actual desired values.
This patch makes it possible to search for the output names of various input
nodes directly. All other outputs of the input node are hidden automatically.
This was partially support for the Scene Time before.
Supported nodes:
* Compositor: Scene Time
* Geometry Nodes: Camera Info, Mouse Position, Scene Time, Viewport Transform
* Shader Nodes: Camera Data, Curves Info, Geometry, Volume Info, Light Path,
Object Info, Particle Info
Right now, the output names are hardcoded in the menu. We don't have a great way
to access those without an actual node instance currently. For that we'll need
to make the node declarations available in Python, which is a good project but
out of scope for this this feature. It also does not seem too bad to have more
explicit control over what's shown in the search.

This patch adds a new Image Coordinates node for the compositor. The
Texture Coordinates and Pixel Coordinates outputs were removed from the
Image Info node and were added to the new node instead. Additionally, a
new Normalized Coordinates output was added.
The Pixel Coordinates output now no longer includes half pixel offsets.
Pull Request: https://projects.blender.org/blender/blender/pulls/138935
This patch adds a new Relative To Pixel node in the compositor. The node
converts values that are relative to the image size to values that are
in terms of pixels.
This is useful to use relative values in nodes that take pixel values.
For instance, the Kuwahara node has an input that defines the filter
size in pixels. If one wants to define it relative to the image size
instead, one can use this node.
The node can operate on float and 2D vector values. Further, the node
can do the conversion relative to a number of image properties:
- Per Dimension: Each dimension gets converted independently. The X
value is relative to the X dimension and the Y value is relative to
the Y dimension. This mode is special because in float mode, the
output will be a factor as opposed to a float.
- X: Relative to the x dimension.
- Y: Relative to the y dimension.
- Greater: Relative to the greater dimension.
- Smaller: Relative to the smaller dimension.
- Diagonal: Relative to the diagonal of the image.

Previously, one had to search for "Time" to get the Scene Time node which
provides access to the current frame and second. Intuitively I often start
searching for "frame" or "seconds" instead and only later remember what I
actually have to search for.
This patch improves the UX by allowing to create a Scene Time node by searching
for "frame" or "seconds" directly. This works in Geometry Nodes and the
compositor.

Previously, it was possible to search for specific math operations in
link-drag-search but not in the normal add menu. This patch adds support for
searching for specific operations in various math nodes.
A good trick for adding e.g. a vector add node is to search for `vadd`
(similarly with `iadd`).
The menu itself looks unchanged. This patch only adds additional elements to the
search.

Texture nodes are already supported through the GPUMaterial and
multi-function compositor abstractions. So we just need to expose them
through the add menu.
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 menu structure currently needs to be duplicated in the code to avoid
adding assets to more than one menu. This was done for geometry nodes
in b49c84276c but was missed for the compositor and shader
nodes. Also remove an unnecessary separator.
Refactor the Add menu in Shading nodes, with manually created menus,
inspired by Geometry Nodes and more recently the Compositor.
Minor sorting adjustments by splitting categories in groups, with
separators in between groups, and sorted alphabetically. Shading
node group assets are also populated in the menus.
This is the first part of the re-organization of the Add menu,
