81fae56cb9 Fix T86298: crash when loading "corrupted" geometry node tree
The file was not really corrupted (as in, Blender did everything
correctly while saving). I only did not consider the case when
a .blend file is resaved in an older version before.

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.

80530edcae Geometry Nodes: Rename "Plane" primitive to "Grid"
Although "Grid" may not be techincally correct since a grid could be 3D,
it was decided to rename the "Plane" primtive to "Grid". The primitive
node allows subdivisions, so the name is more consistent with the
operator in the 3D view.

Following concerns raised in the commit that changed the name initially,

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.

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).

b279fef85d Geometry Nodes: show "Show Texture in texture tab" button
This enables the quick access button [to show the relevant Texture in
the Properties Editor] for textures used in geometry nodes.

This goes in line to what we do for other textures:
- modifier textures have this button
- particle textures have this button
- brush textures will soon have it, too (see D9813)

When outside of the Properties Editor, the button will always show (if a
texture is actually assigned), but will be inactive if no suiting
Properties Editor to show the texture in can be found.

Note this also changes the behavior to not show the button if _no_
texture is assigned (as in: we are still showing the "New" button).
Previously it was always there (e.g. for modifier textures), even if it
would take us to an empty texture tab. (Sure, we could add a texture
there then, but imho it makes more sense to just start showing it once a
texture is already there)

For this to work with geometry nodes, the following chages were done:
- implement foreachTexLink for geonode modifiers
- new buttons_texture_user_node_property_add() that stores prop as well
as node
- also use NODE_ACTIVE_TEXTURE flag in geometry nodetrees

notes:
- this still uses the first suiting (as in: pinning does not interfere)
Properties Editor it finds, this should (maybe?) find the _closest_
Property Editor instead (see related feedback in D9813).
- this will already show the button for brush textures as well
(disabled), but there is another mandatory change in an upcomming commit
to make it work there as well (see D9813)

This concerns currently only collections (`master_collection` of scenes)
and root node trees. It removes the matching type-specific helpers
(`BKE_collection_master_scene_search` and `BKE_node_tree_find_owner_ID`).

No functional change expected here.

NOTE: Current implementation of `owner_get` is far from optimal, we
could probably do it better, see {T69169}.

NOTE: While it could also have it, shapekeys IDTypeInfo was left out of
this change for now. Mainly because it sould not be used currently, and
we ultimately want to demote shape keys from ID status anyway.

461d4fc1aa Geometry Nodes: Node error messages
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.

layout updates accordingly. Links are sorted by their incoming angle
to avoid crossing links. Also, link picking is updated to work with
