This patch adds icons to the right side of nodes when they encounter a
a problem. When hovered, a tooltip displays describing the encountered
while evaluating the node.
Some examples are: attribute doesn't exist, mesh has no faces,
incorrect attribute type, etc. Exposing more messages to the system
will be an ongoing process. Multiple warnings per node are supported.
The system is implemented somewhat generically so that the basic
structure can also be used to store more information from evaluation
for the interface, like a list of available attributes.
Currently the messages are just button tooltips. They could be styled
differently in the future. Another limitation is that every instance of
a node group in a parent node tree will have the same error messages,
the "evaluation context" used to decide when to display the tooltips
must be extended to support node tree paths.

This will allow using C++ data structures to draw node error messages.
This required removing a forward declared enum for grease pencil undo.
Compiles with clang tidy.
When dropping an asset somewhere, it is appended and then a drop operation is
called to actually add it to the scene based on current context. If this drop
operation fails, the appended data-block is now still in the .blend. The user
may not notice and not expect this.
Instead idea is to rollback any changes done by dropping code if the operation
fails, namely removing the appended data-block again.
Adds a new `cancel()` callback which is called if the drop operator returns
`OPERATOR_CANCELLED` to drop-boxes and a generic function to deal with assets
on drop failure.
Also removes the `free_id_on_error` property of the `NODE_OT_add_group`
operator, which was used as ad-hoc solution to get this same behavior.
Adds `NODE_OT_add_group` operator to add a node group from a given name, and
uses that to register a node editor drop-box.
When dropping a node-group asset, the ID will be appended. This is what we do
for other ID assets too.
Should the node group insertion fail (e.g. the group is not compatible with the
current tree, as checked by the poll), the appended data-block is removed.

This is because the node editor added a "real user" to the node group
that it displays. It was mainly added as a hack to solve issues with custom
tree types (T36024). Since we can store id references in custom properties
now, this "real user" is not really necessary anymore.
Given that we are close to a release, I'll only disable line for geometry nodes,
for which the bug has been reported.
Discussed this solution with Hans Goudey.
It's not necessary to check if the link has to be removed,

This commit makes links connected to multi-input sockets spread verticaly
along the socket. Sockets grow if more links are connected and the node
layout updates accordingly. Links are sorted by their incoming angle
to avoid crossing links. Also, link picking is updated to work with
spread links and bezier links.
Currently the multi-input sockets are used in the join geometry node.
The mutli-input sockets look like a vertical rounded rectangle.
Currently they do not support the other custom socket shapes.

This commit moves the property layout callbacks for node types to their
implementation files from `drawnode.c`. This was proposed a while ago in
T75724.
**Benefits**
- Fewer files need to be changed when adding a new node.
- Makes it possible to reuse functions from the node's implementation
in the layout code.
- Except for RNA, all of the node "inputs" are in the same place.
- Code gets shorter overall, avoids the large switch statements.
**Downsides**
- Requires including two UI headers.
- Requires adding an editors dependency to the nodes folder.
This commit only changes function nodes and geometry nodes, more can be
moved later.

This node takes a volume and generates a mesh on it's "surface".
The surface is defined by a threshold value.
Currently, the node only works on volumes generated by the
Points to Volume node. This limitation will be resolved soonish.

This node calculates a distance from each point to the closest position
on a target geometry, similar to the vertex weight proximity modifier.
Mapping the output distance to a different range can be done with an
attribute math node after this node.
A drop-down changes whether to calculate distances from points,
edges, or faces. In points mode, the node also calculates distances
from point cloud points.

Normally sockets only have one input link. This commit adds the back-end
changes needed to use multiple input links per socket.
Multi-input sockets can be defined with a new flag in `bNodeSocketType`.
The changes necessary to make the sockets work in the geometry nodes
evaluator are generalizing input socket values as a vector of values,
and supporting this in the derived node tree structure.
This patch should contain no functional changes. Two upcoming patches
will use this system for the "Join Geometry" node and expose link picking
and updated display in the UI: D10069 and D10181.

In the CompositorOperation::deinitExecution the viewer could be freed at
the same time it was drawn in the image editor or node editor. There is
a guard for that but wasn't added during the migration of the two
editors to the draw manager.
Passing 4x arguments for the rectangle,
mixed in with round-box radius & color wasn't very readable.
Instead, pass a `rctf` as the first argument to UI box drawing functions.
For assets, the copy callback of the drop-box would append the asset
data-block. Check if the operator's poll succeeds before calling the copy
callback.
Otherwise the data-block is "secretly" appended, which the user doesn't expect
and won't notice without checking the file data in the Outliner.
For masks I had to extend the poll function, it didn't check context
sufficiently.
The normal drag & drop support was already there, just needed minor tweaks to
respect asset importing. The dragged in mask will create a mask node for
compositor node editors.

This node allows sampling a texture for every vertex based on some
mapping attribute. Typical attribute names are the name of a uv map
(e.g. "UVMap") and "position". However, every attribute that can be
converted to a vector implicitly is supported.
It should be noted that as of right now, uv map attributes can only be
accessed after a Point Distribute node.

This commit moves runtime-only variables from the `SpaceNode`
DNA struct to a private struct in `node_intern.h`. Before, it was hard
to tell which data needed to be saved in files, this should make it
more clear.
Node that the `edittree` field is basically a runtime variable, since
it's set from the `treepath` list on read, but moving it would require
some more invasive changes that I don't think are worth it right now.
Also, not all of the moved variables were explicitly cleared on read--
`aspect` is set at the start of a redraw, `cursor` is set in a region
callback, and `recalc` was used as an update flag.

By design the modified object transformations should still work and
affect the geometry nodes results. The current behaviour, however, would
make the geometry from the object info to not be affected by the
modified object transformations. This patch changes that by default.
In a similar fashion the Location, Rotation and Scale sockets outputs
should be aware of whether the output should be in the global space or in the
space of the nodetree.
To solve this, the patch introduces a new transformation space "enum"
where users can pick "Original" or "Relative" space.
Original
--------
Output the geometry relative to the input object transform, and the
location, rotation and scale relative to the world origin.
Relative
--------
Bring the input object geometry, location, rotation and scale into the
modified object maintaining the relative position between the two objects in
the scene.
Relative space violates a bit the design of the nodetree. The geometry in this
case is transformed so that moving the modified object doesn't interfere with
the geometry. This is particularly useful for the boolean node for instance.
"Original" is the default space, but old files are set to "Relative" for
backwards compatibility.

These functions with many arguments can be unwieldy. Aside from the obvious issues
with rewriting the list of arguments and the opportunities for error and frustration
that presents, the long list of arguments make these systems hard to change. So when
an argument should be added, someone might skip that and add some hack instead.
So, as proposed in T73586#1037210, this patch instead uses a "params" struct for
each of these callbacks.
- Use param argument for `ARegionType.listener`
- Remove unused window field in region listener
- Use param argument for `SpaceType.listener`
- Use params struct for `ARegionType.message_subscribe`

The green is still distinct from the more turquoise use for geometry, and
they are never used in the same node graph. The use of red makes sense, but
would need changes to other sockets and categories to set it apart well.

The translate node moves every point in the geometry, and the scale
node multiplies the "scale" attribute of the input geometry by its input.
While these operations are already possible with the "Attribute" nodes,
these new nodes fit nicely with the nodes specifically for changing the
"rotation" attribute that already exist, and they provide a simpler way
to do the same thing.
