There are two implementations:
- "Link to Viewer Node"
-- when clicking on a socket directly, link from that socket [done by
first selecting and then taking that selection state into account]
-- otherwise cycles through available sockets
- "Connect to Output" [python operator, made core from Node Wrangler]
-- does not take socket selection into account
-- only cycles through available sockets
So goal is to replicate behavior of "Link to Viewer Node" in "Connect to
Output" in terms of "which socket to link from"
This is done by
- exposing a sockets select state to python
- tweaking the call to bpy.ops.node.select so it does socket selection
as well
- take that selection into account

As described in #122398, implement read and write support for a new
attribute storage system. Currently this is only implemented to support
forward compatibility; the format used at runtime isn't changed at all.
That can be done one step at a time during the 4.5 and 5.0 development
cycles. A new experimental option for testing tells Blender to always
save with the new format.
The main benefit of the new structure is that it matches the attribute
system design, it allows for future attribute storage optimization, and
each attribute is an allocated struct, which will give pointer stability
for the Python API.
The next step is to connect the attribute API and the RNA API to
AttributeStorage for the simplest geometry type, point clouds.

Add a new shader node to control volume coefficients (scattering,
absorption and emission) directly, making it easier to model existing
volumes with measured data.

This adds basic templating support to render output paths. By putting
"{variable_name}" in the path string, it will be replaced by the named
variable's value when generating the actual output path. This is similar
to how "//" is already substituted with the path to the blend file's
current directory.
This templating system is implemented for both the primary render output
path as well as the File Output node in the compositing nodes. Support
for using templates in other places can be implemented in future PRs.
In addition to the "{variable_name}" syntax, some additional syntax is
also supported:
- Since "{" and "}" now have special meaning, "{{" and "}}" are now
escape sequences for literal "{" and "}".
- "{variable_name:format_specifier}", where "format_specifier" is a
special syntax using "#", which allows the user to specify how numeric
variables should be formatted:
- "{variable_name:###}" will format the number as an integer with at
least 3 characters (padding with zeros as needed).
- "{variable_name:.##}" will format the number as a float with
precisely 2 fractional digits.
- "{variable_name:###.##}" will format the number as a float with at
least 3 characters for the integer part and precisely 2 for the
fractional part.
For the primary render output path: if there is a template syntax error,
a variable doesn't exist, or a format specifier isn't valid (e.g. trying
to format a string with "##"), the render that needs to write to the
output path fails with a descriptive error message.
For both the primary and File Output node paths: if there are template
syntax errors the field is highlighted in red in the UI, and a tooltip
describes the offending syntax errors. Note that these do *not* yet
reflect errors due to missing variables. That will be for a follow-up
PR.
In addition to the general system, this PR also implements a limited set
of variables for use in templates, but more can be implemented in future
PRs. The variables added in this PR are:
- `blend_name`: the name of the current blend file without the file
extension.
- `fps`: the frames per second of the current scene.
- `resolution_x` and `resolution_y`: the render output resolution.

The main way to create a new node group right now is to select some nodes and
then press ctrl+G. This works well for the common case when one already has some
nodes to group. However, there is no good alternative currently for when one
wants to create a new group from scratch. A common workaround currently is to
add some dummy node, then press ctrl+G and then to delete the dummy node in the
group again. Obviously, we can do better than that.
This patch adds a `New Group` entry in the menu. It's available in geometry,
compositing and shading Nodes. The operator adds a new node group called
"NodeGroup" (the same default name we use for ctrl+G currently). Then it adds a
new group node and assigns the new group to it. The group itself does not have
any inputs or outputs by default because any such socket would just be a guess
that's likely wrong and more annoying than useful.
A nice side benefit of adding this operator is that the Group menu is not empty
in shading and compositing nodes initially which always looked a bit off.

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.

It always was functionality which got committed without proper review
by the module or UI/UX team. It has all sort of UX problems, but it is
also something that will be tricky to support for HDR drawing.
To brings things to a more manageable state the functionality is now
removed.
With `MESH_OT` prefix, the shortcut was added to wrong
keymap ("object mode", see: `WM_keymap_guess_opname`).
idname of following operations has been changed, they are
only exposed in sculpt mode UI (also see their poll function:
`geometry_extract_poll`):
- `face_set_extract`
- `paint_mask_extract`
- `paint_mask_slice`

Added a new operator `OBJECT_OT_material_slot_remove_all`
that removes all materials from the material slots of selected objects
This was inspired by a request proposal on RCS.

This feature allows you to change postion of origin/pivot for images
without changing their position.
It is implemented as property of transform operator. It is activated
by pressing `Ctrl + .` shortcut.
Move Origin item was also added to transform menu.
Origin can be snapped to 3x3 grid on strip image. This represents
most usual anchor points.

Previously sync-select in edge-select mode behaved in much the same
way as vertex selection, since a selected edge could cause a vertex
on an a disconnected UV island to be selected.
Now single vertices are no longer considered selected when the
Sticky-Mode is set to "Location" (the default).
Notes on changes when sync-select is enabled:
- The main change from a user perspective is edge & face select modes
show the selected edges.
- This resolves a problem in edge & face selection modes where it wasn't
possible to differentiate between a selected edge and two selected
vertices on either side of an unselected edge.
This adds an Import VDB node. It loads all the grids from a .vdb file and hence
outputs a Volume geometry instead of an individual grid.
The grids are cached through the existing volume grid file cache, so they are
automatically deduplicated when volume grids are loaded from files in other
ways.

This adds inital Grease Pencil support for node tools.
Node tools work in `Object Mode`, `Edit Mode`,`Sculpt Mode`,
and `Draw Mode`.
While Grease Pencil has many editing tools, including editing
multiple frames at the same time, for now, node tools only
allow editing the current frame.
Currently, the idea is that node tools can do arbitrary changes
to the drawings, but cannot do changes to the existing layer tree, e.g.
changing the order of layers, removing a layer or groups, etc.
All the node tool specific nodes like `Selection` and `Set Selection`
are adapted to work with Grease Pencil. In `Draw Mode`, we currently
interpret everything as selected.
The `Active Element` node has a `Layer` mode that provides the
index of the active layer (if there is one).
When `Auto-Key` is used, a new keyframe is created on the
current frame.
Locked/invisible layers cannot be edited with node tools.

Exposes bézier handle data through a new `GreasePencilStrokePointHandle`
class on each point, which provides `position`, `type`, and `select` for both
`point.handle_left` and `point.handle_right`.
Also removes the old separate point attributes:
* `handle_left_type`, `handle_right_type`
* `select_handle_left`, `select_handle_right`

Relative imports are intentionally avoided in UI code (`scripts/startup/bl_ui`) because it makes it impossible to run individual files in isolation.
Common workflow for making mock-ups and quick UI edits is to load the UI file in Blender's text editor with "Edit Source" operator, make changes, and run the script to see the changes. But in the current version it's impossible because files include relative imports, which don't allow Python to run scripts individually.

Behavior of select all operator invoked by shortcut was inconsistent
with menu. This was, because operator context was not set.
Also the selection in timeline is cleared when running this operator
as not doing it may cause unexpected behavior for users.
Selection invert also follows the same behavior.

When creating a new action slot for a data-block, via the '+ New' button
of the slot selector, use the name of the slot that was last used by
that data-block. Previously, it would always use the name of the
data-block, interfering with slot auto-selection when toggling between
Actions.

I'm not sure when this stopped working. The function in question is
quite confusing since it's called twice with two different purposes.
Fixing the exception is simple though. Just checking the data type
for "None" prevents changing the data type to one that's invalid given
the context. I didn't find a simple way to add an error message though.

New option to export Viexport Material instead of Node tree:
- Very Fast

Is exported:
- Base Color
- Roughness

Allow assign/select operators to execute when armature tab is pinned.
For assign operators, pinned armature should be active in 3D view
because we cannot assign bones of one armature to the bone collection of
different armature. Added extra condition in poll function to control
the above case.
For select operators, use `ED_armature_context` to obtain pinned Armature.
These operators are now hidden in object modes.

This PR adds an option to only show the onion skins of the active
object. The option is added to the Grease Pencil overlay menu in the
3D viewport.
When enabled, only the onion skins of the active object are shown.
This keeps the viewport a lot cleaner when working with multiple
Grease Pencil objects.
This resolves#136820.

Part of #135062.
This PR adds an Auto Normalize option in the Vertex Group panel that
when checked will normalize the other deform-bone vertex groups' weights
when assigning the weight of a deform-bone vertex group. For example if
a selected vertex has the following weights:
| Name | Weight |
|---------|--------|
| Group 1 | 0.2 |
| Group 2 | 0.2 |
| Group 3 | 0.6 |
And the user selects Group 3, checks the Auto Normalize checkbox, sets
the weight to 0.8, and clicks Assign, the new weights will be:
| Name | Weight |
|---------|--------|
| Group 1 | 0.1 |
| Group 2 | 0.1 |
| Group 3 | 0.8 |
