Only run the node once for every unique geometry set in the input's
instance heirarchy. This can massively improve performance when
there are many instances, but it will mean that the result is the same
for every instance. For the previous behavior, a "Realize Instances"
node can be used before this one.
This node can be changed without versioning since the old material
assign node was already deprecated and replaced.
In a sub-panel it will be clearer that they are outputs, since they
just look like more inputs now. Unfortunately it is not possible to
make sub-panels display conditionally currently, so the output
sub-panel will always be visible whether or not it is empty.

As also explained in D6134, in most case of Stretch To usage in
rigs, it is desirable to use swing rotation, either via the old
method of pairing the constraint with Damped Track, or via the
Swing rotation type introduced in 2.82. This is for instance true
for all usages of the constraint in Rigify.
The reason can be understood by realizing that unlike order-
dependent euler rotations, swing is not biased to an axis, and
isn't affected by gimbal lock effects at merely 90 degrees
of rotation (it has only one singularity at 180 degrees).
Thus it makes sense to change the default for newly created
constraints to the Swing mode. This has no backward compatibility
concerns except for old tutorials and rig generation scripts.

Basically this enables the select-tweaking behavior as per the
guidelines:
https://wiki.blender.org/wiki/Human_Interface_Guidelines/Selection#Select-tweaking.
We use this in most other other editors that allow selecting and
dragging multiple items. But besides the consistency improvement, this
is important if we want to support dragging multiple assets (or files)
in future. We want to support this at least for dragging multiple assets
into an asset catalog for the upcoming asset catalog UI.
With this commit, the distribute points on faces node runs only
once for every unique mesh in its input. That means if there are
100 instances of the same mesh, it will only run once.
This basically reverts rB84a4f2ae68d408301. The optimization there
didn't end up being worth it in the end, since it complicates code
quite a lot. It's also incompatible with this method of dealing with
instances, and it breaks field evaluation for instances, where we would
have to make sure to handle each instance transform properly otherwise,
evaluating the field separately for every instance.

The Asset Catalog Definition File is now saved whenever the blend file
is saved. The location of the CDF depends on where the blend file is
saved, and whether previously a CDF was already loaded, according to the
following rules. The first matching rule wins:
1. Already loaded a CDF from disk? -> Always write to that file.
2. The directory containing the blend file has a
`blender_assets.cats.txt` file? -> Merge with & write to that file.
3. The directory containing the blend file is part of an asset library,
as per the user's preferences? -> Merge with & write to
`${ASSET_LIBRARY_ROOT}/blender_assets.cats.txt`
4. Create a new file `blender_assets.cats.txt` next to the blend file.
Add `BKE_preferences_asset_library_containing_path(&U, some_path)` that
finds the asset library that contains the given path.
This is a simple linear search, returning the first asset library that
matches. There is no smartness when it comes to nested asset libraries
(like returning the library with the best-matching path), although this
could be a useful feature to add later.
Add function `BLI_path_contains(container, containee)` that returns true
if and only `container` contains `containee`.
Paths are normalised and converted to native path separators before
comparing. Relative paths are *not* made absolute, to simplify the
function call; if this is necessary the caller has to do this conversion
first.
`BKE_object_material_slot_used` would only check obdata usages, but
particle settings can also (weirdly enough) use objects' material slots.
So now, as its name suggests, `BKE_object_material_slot_used` does take
an object as parameter, and also checks for potential slot usage from
psys in the object.

This patch allows passing a field to the modifier as output. In the
modifier, the user can choose an attribute name. The attribute
will be filled with values computed by the field. This only works
for realized mesh/curve/point data. As mentioned in T91376, the
output domain is selected in the node group itself. We might want
to add this functionality to the modifier later as well, but not now.

For some reason was assuming setting a property in RNA would call its
update callback if any, but this actually needs to be done separately.
So add this call to `rna_property_override_operation_apply`.
There are cases where there is no way to ensure we do have/know about an
active scene. Further more, this should not be required to perform
'real' updates on data, only to perform additional special handling in
current scene (mostly related to editing tools, UI, etc.).
This pointer is actually almost never used in practice, and half of its current
usages are fairly close to abuse of the system (like calls to
`ED_gpencil_tag_scene_gpencil` or `BKE_rigidbody_cache_reset`).
This commit ensures that the few places using this 'active scene' pointer are
safely handling the `NULL` case, and clearly document the fact that a
NULL scene pointer is valid.
Scene passed to the update callback is the active scene it //may// not
be that actual ID owner of the affected data (although in practice it
should always be currently).
This makes it easier to spot which links contain fields and which
contain data. Actually, the patch makes all other links a bit thicker.
However, with soon-to-be-implemented theme changes, the
perceived thickness will be the same as before.

The original limit dates back from 2002 when Blender went open source.
After that many years some productions (e.g., Sprite Fright) are already
experiencing limitations for complex edits.
The future plans is to support an initial shorter (2?) number of
channels with support to "unlimited" channels.
Finally, I'm bumping the minimum file requirement since files with more
than 32 channels won't work well in old Blender versions.
In a future commit I will implement a sanitization so that we only read (and write)
128 channels. Making sure future changes of this number won't corrupt Blender.

This adds the ability to cancel out of the roll using ESC or RMB
(which is not common for viewops -- but makes sense in the case of roll
I think). This resets the view as well as potential locked cameras to
the original orientations (but does not remove potential autokeys --
which no transform does on cancel btw.)

Since its introduction in {rB5c569d227b64}, the view roll was based on
horizontal movement only. Using a "real" angle not only feels more
natural but also has the benefit of getting more precission the further
away from the center you are (just like regular rotation, brush/stencil
rotation etc.). A similar thing has already been implemented in the
Grease Pencil Tools Addon, now make the blender standard roll the same.
Since this is not using the transform system, we are still lacking a
line in the viewport (this could be added but since this is always based
on the center of the view we dont necessarily need this), as well as the
additional Shift-extra-precission behavior.

Proxy conversion is a fairly particular case of liboverride creation, in
which remapping all local usages of linked data probably makes more
sense, rather than only doing so whitin the overridden 'group' of IDs.
Introduce `BKE_callback_remove()`, which undoes the effect of
`BKE_callback_add()`. It also respects `funcstore->alloc` by freeing the
removed `funcstore` when needed.
This allows for shorter-lived objects in memory to unregister their
callbacks at the end of their lifespan.
`BKE_callback_global_finalize()` has been adjusted so that the
responsibility "remove a callback" is given to one function only.

This adds a new Instance on Points node that is a replacement
for the old Point Instance node. Contrary to the old node,
it does not have a mode to instance objects or collections
directly. Instead, the node has to be used with an Object/
Collection Info to achieve the same effect.
Rotation and scale of the instances can be adjusted in the node
directly or can be controlled with a field to get some variation
between instances.
The node supports placing different instances on different points.
The user has control over which instance is placed on which point
using an Instance Index input. If that functionality is used, the
Instance Geometry has to contain multiple instances that can are
instanced separately.

This adds two new input sockets to the Collection Info node:
* `Separate Children`: When turned off, the entire collection is output as a single
collection instance (same behavior as before). When turned on, each child of
the collection is output as a separate instance (children can be objects and collections).
Toggling this input should not change the visual transforms of the output geometry.
* `Reset Children`: Only used when `Separate Children` is on. When used, the transforms
of the instances are reset to the origin. This is useful when one wants to e.g. instance
the collection children separately in the upcoming instancing node.
