3494946560 Nodes: implement dot graph exporter for derived node tree
This visualization of nested node groups makes it easier to debug
some issues. Muted nodes, muted links, reroute nodes and unavailable
sockets are removed from the visualization to keep it clean.

Nested node groups are visualized using colored clusters.

9b806c49d0 Geometry Nodes: Refactor / fix point separate node
The point separate node was failing in situations where one of the
outputs was empty. In addition, the code was not structured very well.
This new implementation stores less temporary information, is more
geometry component type agnostic, and is more self-descriptive.
It also solves the problems mentioned above.

a41d3c0ebe Geometry Nodes: Rename "Subdivide Smooth" back to "Subdivision Surface"
Following concerns raised in the commit that changed the name initially,
rB2e19509e60b39837, it makes more sense to keep the "Surface" name for
this node because it has a specific meaning that should not be confused
with other types of subdivision.

0ff3f96a1b Nodes: make derived link data more obvious in NodeTreeRef
`NodeTreeRef` is a thin wrapper on top of `bNodeTree`. By default it
should not hide anything from the underlying `bNodeTree` (before this
it was hiding muted links).

For convenience some "derived" data is cached on sockets. For example
all the connected sockets when reroutes and muted links are ignored.

A nice side benefit of this refactor is that `NodeTreeRef` requires
less memory than before.

266cd7bb82 Nodes: Add support to mute node wires
This patch adds the ability to mute individual wires in the node editor.
This is invoked like the cut links operator but with a new shortcut.

Mute = Ctrl + Alt
Cut = Ctrl

Dragging over wires will toggle the mute state for that wire.
The muted wires are drawn in red with a bar across the center.
Red is used in the nodes context to indicate invalid links, muted links and internal links.

When a wire is muted it exposes the original node buttons which are normally hidden when a wire is connected.

Downstream and upstream links connected using reroute nodes are also muted.

Outside scope of patch:
- Add support for pynodes e.g. Animation Nodes
- Requires minor change to check for muted links using the `is_muted` link property or the `is_linked` socket property.

9a56a3865c Geometry Nodes: Add initial version of mesh primitives
This commit includes nodes to build the following primitives:
 - Cone
 - Cylinder
 - Circle
 - Cube
 - UV Sphere
 - Ico Sphere
 - Line
 - Plane/Grid

In general the inputs are the same as the corresponding operators
in the 3D view.

**Line Primitive**
The line primitive has two modes-- adding vertices between two end
points, or adding vertices each at an offset from the start point.
For the former mode, there is a choice between a vertex count
and a distance between each point.

**Plane Primitive**
This commit includes the "Plane" and "Grid" primitives as one node.
Generally primitives are named after the simpler form of the shape they
create (i.e. "Cone" can make some more complex shapes). Also, generally
you want to tweak the number of subdivisions anyway, so defaulting to
plane is not an inconvenience. And generally having fewer redundant
base primitives is better.

**Future Improvements**
A following patch proposes to improve the speed of the cylinder, cone,
and sphere primitives: D10730. Additional possible future improvements
would be adding subdivisions to the cube node and rings to the cone
and cylinder nodes.

d49e7b82da Compositor: Redesign Cryptomatte node for better usability
In the current implementation, cryptomatte passes are connected to the node
and elements are picked by using the eyedropper tool on a special pick channel.

This design has two disadvantages - both connecting all passes individually
and always having to switch to the picker channel are tedious.

With the new design, the user selects the RenderLayer or Image from which the
Cryptomatte layers are directly loaded (the type of pass is determined by an
enum). This allows the node to automatically detect all relevant passes.

Then, when using the eyedropper tool, the operator looks up the selected
coordinates from the picked Image, Node backdrop or Clip and reads the picked
object directly from the Renderlayer/Image, therefore allowing to pick in any
context (e.g. by clicking on the Combined pass in the Image Viewer). The
sampled color is looked up in the metadata and the actual name is stored
in the cryptomatte node. This also allows to remove a hash by just removing
the name from the matte id.

Technically there is some loss of flexibility because the Cryptomatte pass
inputs can no longer be connected to other nodes, but since any compositing
done on them is likely to break the Cryptomatte system anyways, this isn't
really a concern in practise.

In the future, this would also allow to automatically translate values to names
by looking up the value in the associated metadata of the input, or to get a
better visualization of overlapping areas in the Pick output since we could
blend colors now that the output doesn't have to contain the exact value.

ba3a0dc9ba Geometry Nodes: Add "normal" attribute for face normals
This commit adds a `normal` attribute on the polygon domain. Since
normal data is derived data purely based off of the location of each
face's vertices, it is exposed as a read-only attribute. After
rB80f7f1070f17, this attribute can be interpolated to the other domains.

Since this attribute is a special case compared to the others, the
implementation subclasses `BuiltinAttributeProvider`. It's possible
there is a better way to abstract this. Something else might also
become apparent if we add similar read-only attributes.

See rB2966871a7a891bf36 for why this is preferred over the previous
implementation.

670453d1ec Geometry Nodes: Add Attribute Convert node
The Attribute Convert node provides functionality to change attributes
between different domains and data types. Before it was impossible to
write to a UV Map attribute with the attribute math nodes since they
did not output a 2D vector type. This makes it possible to
"convert into" a UV map attribute.

The data type conversion uses the implicit conversions provided by
`\nodes\intern\node_tree_multi_function.cc`.

The `Auto` domain mode chooses the domain based on the following rules:
1. If the result attribute already exists, use that domain.
2. If the result attribute doesn't exist, use the source attribute domain.
3. Otherwise use the default domain (points).

The multi-input-socket cannot be connected to the same socket twice currently.
However, it is still possible to achieve this using an intermediate reroute node.

This patch exposes the "Shade Smooth" value as a boolean attribute.
This setting is exposed as a check-box in the mesh data properties,
but the value is actually stored for every face, allowing some faces

One bonus, this allows at least a workaround to the lack of control
of whether meshes created by nodes are shaded smooth or not: just use
an attribute fill node.

84a4f2ae68 Geometry Nodes: Improve performance of point distribute node
This commit refactors the point distribute node to skip realizing
the instances created by the point instance node or the collection
and object info nodes. Realizing instances is not necessary here
because it copies all the mesh data and and interpolates all
attributes from the instances when this operation does not
need to modify the input geometry at all.

In the tree leaves test file this patch improves the performance of
the node by about 14%. That's not very much, the gain is likely larger
for more complicated input instances with more attributes (especially
attributes on different domains, where interpolation would be necessary
to join all of the instances). Another possible performance improvement
would be to parallelize the code in this node where possible.

The point distribution code unfortunately gets quite a bit more
complicated because it has to handle the complexity of having many
inputs instead of just one.

Note that this commit changes the randomness of the distribution
in some cases, as if the seed input had changed.

down on other non-manifold meshes that don't have holes and didn't

This adds a hole_tolerant parameter, false by default, that the user

Using false for this parameter speeds up the time from 90 seconds
