This patch adds the core realtime compositor evaluator as well as a
compositor draw engine powered by the evaluator that operates in the
viewport. The realtime compositor is a new GPU accelerated compositor
that will be used to power the viewport compositor imminently as well as
the existing compositor in the future.
This patch only adds the evaluator and engine as an experimental
feature, the implementation of the nodes themselves will be committed
separately.

There was already a utility to retrieve the correct node group idname
from the context, `node_group_idname`, but often it's clearer to
use lower-level arguments, or the context isn't accessible.
Storing the group idname in the tree type makes it accessible
without rewriting it elsewhere.

This name doesn't require understanding of fields, and
is phrased as an action which is consistent with other nodes.

This adds three new nodes:
* `Shortest Edge Paths`: Actually finds the shortest paths.
* `Edge Paths to Curves`: Converts the paths to separate curves.
This may generate a quadratic amount of data, making it slow
for large meshes.
* `Edge Paths to Selection`: Generates an edge selection that
contains all edges that are part of a path. This can be used
with the Separate Geometry node to only keep the edges that
are part of a path. For large meshes, this approach can be
much faster than the `Edge Paths to Curves` node, because
less data is created.

Curves that are attached to a surface can now follow the surface when
it is modified using shape keys or modifiers (but not when the original
surface is deformed in edit or sculpt mode).
The surface is allowed to be changed in any way that keeps uv maps
intact. So deformation is allowed, but also some topology changes like
subdivision.
The following features are added:
* A new `Deform Curves on Surface` node, which deforms curves with
attachment information based on the surface object and uv map set
in the properties panel.
* A new `Add Rest Position` checkbox in the shape keys panel. When checked,
a new `rest_position` vector attribute is added to the mesh before shape
keys and modifiers are applied. This is necessary to support proper
deformation of the curves, but can also be used for other purposes.
* The `Add > Curve > Empty Hair` operator now sets up a simple geometry
nodes setup that deforms the hair. It also makes sure that the rest
position attribute is added to the surface.
* A new `Object (Attach Curves to Surface)` operator in the `Set Parent To`
(ctrl+P) menu, which attaches existing curves to the surface and sets the
surface object as parent.
Limitations:
* Sculpting the procedurally deformed curves will be implemented separately.
* The `Deform Curves on Surface` node is not generic and can only be used
for one specific purpose currently. We plan to generalize this more in the
future by adding support by exposing more inputs and/or by turning it into
a node group.

This commit adds new Unwrap and Pack Islands nodes, with equivalent
functionality to the existing Unwrap and Pack Islands operators. The
Unwrap node uses generic boolean attributes to determine seams instead
of looking at the seam flags in the mesh geometry.
Unlike the Unwrap operator, the Unwrap node doesn't perform aspect
ratio correction, because this is trivial for the user to implement
with a Vector Math node if it is desired.
The Unwrap node implicitly performs a Pack Islands operation upon
completion, because the results may not be generally useful otherwise.
This matches the behaviour of the Unwrap operator.
The nodes use the existing Vector socket type, and do not introduce a
new 2D Vector type (see T92765).

As described in T98943, this commit adds a node that can
evaluate a field on a separate domain in a larger field context.
This is potentially useful in many cases, to avoid relying on
a separate capture attribute node, which can make it easier
to build reusable fields that don't need geometry inputs.
Internally, the node just evaluates the input field in the larger
field context and then uses the generic domain interpolation,
so the code is simple. One future optimization might be using
the input selection to only evaluate part of the input field, but
then the selection has to be interpolated as well, and that might
not always be worth it.

Inspired by D12936 and D12929, this patch adds general purpose
"Combine Color" and "Separate Color" nodes to Geometry, Compositor,
Shader and Texture nodes.
- Within Geometry Nodes, it replaces the existing "Combine RGB" and
"Separate RGB" nodes.
- Within Compositor Nodes, it replaces the existing
"Combine RGBA/HSVA/YCbCrA/YUVA" and "Separate RGBA/HSVA/YCbCrA/YUVA"
nodes.
- Within Texture Nodes, it replaces the existing "Combine RGBA" and
"Separate RGBA" nodes.
- Within Shader Nodes, it replaces the existing "Combine RGB/HSV" and
"Separate RGB/HSV" nodes.
Python addons have not been updated to the new nodes yet.
**New shader code**
In node_color.h, color.h and gpu_shader_material_color_util.glsl,
missing methods hsl_to_rgb and rgb_to_hsl are added by directly
converting existing C code. They always produce the same result.
**Old code**
As requested by T96219, old nodes still exist but are not displayed in
the add menu. This means Python scripts can still create them as usual.
Otherwise, versioning replaces the old nodes with the new nodes when

This patch adds color attributes to TexPaintSlot. This allows an easier selection
when painting color attributes.
Previously when selecting a paint tool the user had to start a stroke, before the
UI reflected the correct TexPaintSlot. Now when switching the slot the active
tool is checked and immediate the UI is drawn correctly.
In the future the canvas selector will also be used to select an image or image texture node
to paint on. Basic implementation has already been done inside this patch.
A limitation of this patch is that is isn't possible anymore to rename images directly from
the selection panel. This is currently allowed in master. But as CustomDataLayers
aren't ID fields and not owned by the material supporting this wouldn't be easy.
{F12953989}
In the future we should update the create slot operator to also include color attributes.
Sources could also be extended to use other areas of the object that use image textures
(particles, geom nodes, etc... ).

This commit removes the implementations of legacy nodes,
their type definitions, and related code that becomes unused.
Now that we have two releases that included the legacy nodes,
there is not much reason to include them still. Removing the
code means refactoring will be easier, and old code doesn't
have to be tested and maintained.
After this commit, the legacy nodes will be undefined in the UI,
so 3.0 or 3.1 should be used to convert files to the fields system.
The net change is 12184 lines removed!
The tooltip for legacy nodes mentioned that we would remove
them before 4.0, which was purposefully a bit vague to allow
us this flexibility. In a poll in a devtalk post showed that the
majority of people were okay with removing the nodes.

Added a new "Sharpen Less" kernel to the filter compositor node. The intent here is to provide a much less aggressive sharpening filter that can't simply be solved by toning down the factor on the existing sharpen filter.
The existing "Sharpen" filter uses a "box" kernel:
```
-1 -1 -1
-1 9 -1
-1 -1 -1
```
The new "Sharpen Less" filter uses a "diamond" kernel:
```
0 -1 0
-1 5 -1
0 -1 0
```
The difference between the two is clear to see in the following side-by-side:

This patch makes it possible to set the UI color of a node's
header bar and override the default from the node's typeinfo.
Currently the color is taken from the `.nclass`
member of the node's bNodeType->TypeInfo struct.
This is created once when registering the node.
The TypeInfo is used for both UI and non-UI functionality.
Since the TypeInfo is shared, the header bar for the node
can't be changed without changing all nodes of that type.
The Map Range node is shown as a `Converter` or blue color by default.
This patch allows this to be changed dynamically to `Vector` or purple.
This is done by adding a `ui_class` callback to node typeinfo struct.

This implements a merge by distance operation for point clouds.
Besides the geometry input, there are two others-- a selection
input to limit the operation to certain points, and the merge
distance. While it would be a reasonable feature, the distance
does not support a field currently, since that would make
the algorithm significantly more complex.
All attributes are merged to the merged points, with the values
mixed together. This same generic method is used for all attributes,
including `position`. The `id` attribute uses the value from the
first merged index for each point.
For the implementation, most of the effort goes into creating a
merge map to speed up attribute mixing. Some parts are inherently
single-threaded, like finding the final indices accounting for the
merged points. By far most of the time is spend balancing the
KD tree.
Mesh support will be added in the next commit.

This patch introduces an extrude node with three modes. The vertex mode
is quite simple, and just attaches new edges to the selected vertices.
The edge mode attaches new faces to the selected edges. The faces mode
extrudes patches of selected faces, or each selected face individually,
depending on the "Individual" boolean input.
The default value of the "Offset" input is the mesh's normals, which
can be scaled with the "Offset Scale" input.
**Attribute Propagation**
Attributes are transferred to the new elements with specific rules.
Attributes will never change domains for interpolations. Generally
boolean attributes are propagated with "or", meaning any connected
"true" value that is mixed in for other types will cause the new value
to be "true" as well. The `"id"` attribute does not have any special
handling currently.
Vertex Mode
- Vertex: Copied values of selected vertices.
- Edge: Averaged values of selected edges. For booleans, edges are
selected if any connected edges are selected.
Edge Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected extruded
edges. For booleans, the edges are selected if any connected
extruded edges are selected.
- Duplicate edges: Copied values of selected edges.
- Face: Averaged values of all faces connected to the selected edge.
For booleans, faces are selected if any connected original faces
are selected.
- Corner: Averaged values of corresponding corners in all faces
connected to selected edges. For booleans, corners are selected
if one of those corners are selected.
Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected selected
edges, not including the edges "on top" of extruded regions.
For booleans, edges are selected when any connected extruded edges
were selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
Individual Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of the two neighboring
edges on each extruded face. For booleans, edges are selected
when at least one neighbor on the extruded face was selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
**Differences from edit mode**
In face mode (non-individual), the behavior can be different than the
extrude tools in edit mode-- this node doesn't handle keeping the back-
faces around in the cases that the edit mode tools do. The planned
"Solidify" node will handle that use case instead. Keeping this node
simpler and faster is preferable at this point, especially because that
sort of "smart" behavior is not that predictable and makes less sense
in a procedural context.
In the future, an "Even Offset" option could be added to this node
hopefully fairly simply. For now it is left out in order to keep
the patch simpler.
**Implementation**
For the implementation, the `Mesh` data structure is used directly
rather than converting to `BMesh` and back like D12224. This optimizes
for large extrusion operations rather than many sequential extrusions.
While this is potentially more verbose, it has some important benefits:
First, there is no conversion to and from `BMesh`. The code only has
to fill arrays and it can do that all at once, making each component of
the algorithm much easier to optimize. It also makes the attribute
interpolation more explicit, and likely faster. Only limited topology
maps must be created in most cases.
While there are some necessary loops and allocations with the size of
the entire mesh, I tried to keep everything I could on the order of the
size of the selection rather than the size of the mesh. In that respect,
the individual faces mode is the best, since there is no topology
information necessary, and the amount of work just depends on the size
of the selection.
Modifying an existing mesh instead of generating a new one was a bit
of a toss-up, but has a few potential benefits:
- Avoids manually copying over attribute data for original elements.
- Avoids some overhead of creating a new mesh.
- Can potentially take advantage of future ammortized mesh growth.
This could be changed easily if it turns out to be the wrong choice.

Currently there is no way to flip normals in geometry nodes. This node
makes that possible by flipping the winding order of selected faces.
The node is purposely not called "Flip Normals", because normals are
derived data, changing them is only a side effect. The real change is
that the vertex and edge indices in the face corners of every selected
polygon are reversed, and face corner attribute data is reversed.
While there are existing utilities to flip a polygon and its custom
data, this node aims to process an attribute's data together instead
of processing all attributes separately for each index.

It is similar to the Transfer Attribute node in Index mode. The main difference

This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.
I would like to give a huge thanks to @JacquesLucke who helped during this
and pushed me to reduce the duplication further.

know @Howard Trickey (howardt) opinion on the matter.
- The noexcept on the copy constructor of mpq(2|3) is being removed.
But according to @Jacques Lucke (JacquesLucke) it is not a real problem
for now.
I would like to give a huge thanks to @Jacques Lucke (JacquesLucke) who
helped during this and pushed me to reduce the duplication further.

The main issue was the use of `G_MAIN` during file load.
This patch refactors the code so that iterating over `G_MAIN`
is not necessary anymore. See D13800 for more details.

The value of this flag was only retrieved in `nodeGetActiveID`, which
wasn't used anywhere. Other than that, the `NODE_ACTIVE_ID` and
related functions seem to come from the Blender internal renderer.

Conversion is skipped when converting between the same color spaces or to or from data spaces.
Implementation done for tiled and full frame compositor.

incorrect comments, and defines that have been commented for years

MSVC used to warn about const mismatch for arguments passed by value.
Remove these as newer versions of MSVC no longer show this warning.

This flag is only used a few small cases, so instead
of setting the flag for every node only set the
required flag for the nodes that require it.
Mostly the flag is used to set `ntype.flag = NODE_PREVIEW`
For nodes that should have previews by default which
is only some compositor nodes and some texture nodes.
The frame node also sets the `NODE_BACKGROUND` flag.
All other nodes were setting a flag of 0 which has no purpose.
