805d947810 Compositor: Add Anti-Aliasing node
This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA)

The algorithm was proposed by:
  Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez

This node provides only SMAA 1x mode, so the operation will be done with no spatial
multisampling nor temporal supersampling. See Patch for comparisons.

The existing AA operation seems to be used only for binary images by some other nodes.
Using SMAA for binary images needs no important parameter such as "threshold", so we
perhaps can switch the operation to SMAA, though that changes existing behavior.

Notes:
1. The program code assumes the screen coordinates are DirectX style that the
   vertical direction is upside-down, so "top" and "bottom" actually represent bottom
   and top, respectively.

Thanks for Habib Gahbiche (zazizizou) to polish and finalize this patch.

a363d64b93 UI: Use correct property split ratio for node socket buttons
This makes the buttons drawn on nodes for unconnected string and color
sockets draw with the correct 40% ratio for the label split rather than
the old 50% ratio not used elsewhere in Blender anymore. The benefit is
a cleaner look, because the button edges line up better with others, and
a bit more space to type in attribute names.

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.

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.

85421c4fab Geometry Nodes: Attribute search drop-down
This commit adds a search for existing attributes when you click
on an attribute field. This is useful because otherwise you have
to remember which attributes should be available at each node in
the tree.

The fundamental complication is that this information is not
accessible statically. So the search data is only a cache from
the previous node tree evaluation. The information is added
with `BKE_nodetree_attribute_hint_add`, currently for every
input geometry socket for a single node.

This is only an initial implementation, and later versions will
expose the data type and domain of the attributes.

8f707a72e8 UI: Multi-input node socket spacing and interaction
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.

cfa48c84d0 Cleanup: Register node property layout callbacks in files
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.

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--

8b777ee6d6 Geometry Nodes - Object Info: option to apply obj transform to the geometry
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.

2250b5cefe UI: Redesigned data-block selectors
The previous design is rather old and has a couple of problems:

* Scalability: The current solution of adding little icon buttons next to the
  data-block name field doesn't scale well. It only works if there's a small
  number of operations. We need to be able to place more items there for better
  data-block management. Especially with the introduction of library overrides.
* Discoverability: It's not obvious what some of the icons do. They appear and
  disappear, but it's not obvious why some are available at times and others
  not.
* Unclear Status: Currently their library status (linked, indirectly linked,
  broken link, library override) isn't really clear.
* Unusual behavior: Some of the icon buttons allow Shift or Ctrl clicking to
  invoke alternative behaviors. This is not a usual pattern in Blender.

This patch does the following changes:

* Adds a menu to the right of the name button to access all kinds of operations
  (create, delete, unlink, user management, library overrides, etc).
* Make good use of the "disabled hint" for tooltips, to explain why buttons are
  disabled. The UI team wants to establish this as a good practise.
* Use superimposed icons for duplicate and unlink, rather than extra buttons
  (uses less space, looks less distracting and is a nice + consistent design
  language).
* Remove fake user and user count button, they are available from the menu now.
* Support tooltips for superimposed icons (committed mouse hover feedback to
  master already).
* Slightly increase size of the name button - it was already a bit small
  before, and the move from real buttons to superimposed icons reduces usable
  space for the name itself.
* More clearly differentiate between duplicate and creating a new data-block.
  The latter is only available in the menu.
* Display library status icon on the left (linked, missing library, overridden,
  asset)
* Disables "Make Single User" button - in review we weren't sure if there are
  good use-cases for it, so better to see if we can remove it.

Note that I do expect some aspects of this design to change still. I think some
changes are problematic, but others disagreed. I will open a feedback thread on

3deb21055a Geometry Nodes: support randomly picking instances from collection
This uses the "id" attribute to randomly pick instances from a collection
for each point.

There is one issue. When the collection is updated (e.g. when an object is
added to it), the nodes modifier is not automatically updated. It seems
like we don't have the infrastructure to support this dependency yet.
The same issue exists in the Boolean modifier and with collision collections.
This should be solved separately soonish.

When "Whole Collection" is disabled, one direct child of the input collection
is instanced at each point. A direct child can be an object or a collection.

Currently, all objects are picked approximately equally often. In the future,
we will provide more control over which point gets which instance.

48ddb94a26 Geometry Nodes: Point separate and attribute compare nodes
This patch adds two related nodes, a node for separating points
and mesh vertices based on a boolean attribute input, and a node
for creating boolean attributes with comparisons.

See the differential for an example file and video.

Point Separate (T83059)
The output in both geometries is just point data, contained in the mesh
and point cloud components, depending which components had data in the
input geometry. Any points with the mask attribute set to true will be
moved from the first geometry output to the second. This means that
for meshes, all edge and face data will be removed. Any point domain
attributes are moved to the correct output geometry as well.

Attribute Compare (T83057)
The attribute compare does the "Equal" and "Not Equal" operations by
comparing vectors and colors based on their distance from each other.
For other operations, the comparison is between the lengths of the
vector inputs. In general, the highest complexity data type is used
for the operation, and a new function to determine that is added.

348bd319d5 Geometry Nodes: Attribute Fill Node
This commit adds a node that fills every element of an attribute
with the same value. Currently it supports float, vector, and color
attributes. An immediate use case is for "billboard" scattering.

Currently people are using the same input to a Random Attribute node's
min and max input to fill every element of a vector with the same value,
which is an unintuitive way to accomplish the same thing.
