Translating an image in fullframe compositor now also translates
the backdrop image for the viewer node.
Attached gif shows the behavior. Notice how gizmo moves with correct
values with the image but the frame stays to indicate what will get
rendered.
Note: This patch is a continuation of [D12750]
(https://archive.blender.org/developer/D12750). In a previous patch,
display offset on screen was not computed correctly. This has now
been fixed.

The crash is fixed by reverting 87fd798ae3 and
some follow up commits. While it would generally be nice to move to a more
SoA format for these things, we are not there yet and this is causing more
trouble than it's worth currently. The main difficulty is that the socket
indices are changed by many different operations which invalidates the array
too often and led to many follow up bugs.

Pull Request: blender/blender#105750
Nodes are sorted based on the selection. In some cases (even depending
on processor speed, nodes can be selected and reordered, and another
operation can run before the next redraw). That gives a window where
operators mapped to the same input as selection can run with invalid
socket locations (which aren't updated after the nodes are reordered,
since they are stored in a separate array).
To fix this, move the socket locations from the node editor runtime
data to the node tree, tag them as invalid when the nodes are
reordered, and check for that status in a few more places.
A better longer term solution is not reordering nodes based on
UI status and instead storing the UI drawing order separately.
Pull Request #104420
When building a node group that's meant to be used directly in the
node editor as well as in the modifier, it's useful to be able to have
some inputs that are only meant for the node editor, like inputs that
only make sense when combined with other nodes.
In the future we might have the ability to only display certain assets
in the modifier and the node editor, but until then this simple solution
allows a bit more customization.
Pull Request #104517
Socket locations are set while drawing the node tree in the editor.
They can always be recalculated this way based on the node position and
other factors. Storing them in the socket is misleading. Plus, ideally
sockets would be quite small to store, this helps us move in that
direction.
Now the socket locations are stored as runtime data of the node editor,
making use of the new node topology cache's `index_in_tree` function
to make a SoA layout possible.

When these declarations are built without the help of the special
builder class, it's much more convenient to set them directly rather
than with a constructor, etc. In most other situations the declarations
should be const anyway, so theoretically this doesn't affect safety too
much. Most construction of declarations should still use the builder.
* This patch just moves runtime data to the runtime struct to cleanup
the dna struct. Arguably, some of this data should not even be there
because it's very use case specific. This can be cleaned up separately.
* `miniwidth` was removed completely, because it was not used anywhere.
The corresponding rna property `width_hidden` is kept to avoid
script breakage, but does not do anything (e.g. node wrangler sets it).
* Since rna is in C, some helper functions where added to access the
C++ runtime data from rna.
* This size of `bNode` decreases from 432 to 368 bytes.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.

The only real difference between `GPU_SHADER_2D_UNIFORM_COLOR` and
`GPU_SHADER_3D_UNIFORM_COLOR` is that in the vertex shader the 2D
version uses `vec4(pos, 0.0, 1.0)` and the 3D version uses
`vec4(pos, 1.0)`.
But VBOs with 2D attributes work perfectly in shaders that use 3D
attributes. Components not specified are filled with components from
`vec4(0.0, 0.0, 0.0, 1.0)`.
So there is no real benefit to having two different shader versions.
This will simplify porting shaders to python as it will not be
necessary to use a 3D and a 2D version of the shaders.
In python the new name for '2D_UNIFORM_COLOR'' and '3D_UNIFORM_COLOR'
is 'UNIFORM_COLOR', but the old names still work for backward
compatibility.

Now dragged handles are handled separately, and the function returns a
statically sized array by value. The functions are also renamed to be
more consistent with curve naming elsewhere in Blender.
Several visual tweaks to node links to make them overall fit in
better with the look of the node editor:
- Change the link thickness with the zoom level to a certain degree.
- Remove the fuzziness of the node link and its shadow/outline.
- The link outline color can now be made transparent.
- Add circles at the end of dragged links when connecting to sockets.
- Improve the banding of the color interpolation along the link.
- Adjust the spacing of dashes along straight node links.

This patch is a response to T92588 and is implemented
as a Function/Shader node.
This node has support for Float, Vector and Color data types.
For Vector it supports uniform and non-uniform mixing.
For Color it now has the option to remove factor clamping.
It replaces the Mix RGB for Shader and Geometry node trees.
As discussed in T96219, this patch converts existing nodes
in .blend files. The old node is still available in the
Python API but hidden from the menus.

Removes the following macros for scene/render frame values:
- `CFRA`
- `SUBFRA`
- `SFRA`
- `EFRA`
These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):

CFRA = some_frame_nbr;

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
opening .blend files.

Fix small cosmetic issues with the reroute node:
1. Remove special case that allowed curved links to attach vertically.
2. Center align the reroute node's label.
The vertically attached node links could lead to kinks in the otherwise
smooth curves. This would break the visual flow and make the link
potentially intersect the node's label.
The center alignment of the label gives more consistent results for
different label lengths and also reduces the chance of the label
interfering with the node links.

This is only part of the experimental "Full Frame" mode (disabled
by default). See T88150.
Currently the viewer node uses buffer paddings to display image offset
in the backdrop as a temporal solution implemented for {D12466}.
This solution is inefficient memory and performance-wise. Another
issue is that the paddings are part the image when saved.
This patch instead sets the offset in the Viewer node image
as variables and makes the backdrop take it into account
when drawing the image or any related gizmo.

Previously, node selection made no distinction between a frame node and
other nodes. So a frame node would be selected by their whole rect or
center (depending on box/lasso/circle select). As a consequence of this,
box and lasso could not pratically be started inside a frame node (with
the intention to select a subset of contained child nodes) because the
frame would be selected immediately and tweak-transforming started.
Circle selecting would always contain the frame node as well (making
transforming a subset of nodes without also transforming the whole frame
impossible).
Now change selection behavior so that for all selection modes only the
border [the margin area that is automatically added around all nodes,
see note below] of a frame node is considered in selection. This makes
for a much more intuitive experience when arranging nodes inside frames.
note: to make the area of interest for selection/moving more obvious,
the cursor changes when hovering over (as is done for resizing).
note: this also makes the resize margin consistent with other nodes.
note: this also fixes right resize border (was exclusive instead of
inclusive as every other border)
Also fixes T46540.
This commit moves code in all node editor files to the

Route cause was data alignment mismatch between GPU and CPU. This
mismatch would not allow us to bind the UBO where data wasn't available

Fixed by using float4 in stead of float2. This could eventually be
packed, but that would lead to less readable code.
