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.
Ref T82689
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.

This commit adds the "Save as Render" feature to the file output node,
that allows to disable the application of the configured view transform
and other color management settings on the image. If disable it uses
the standard view transform instead. This feature was originally
suggested in T83842 and is part of the color management improvements
task in T68926. With this feature it is possible to toggle the
application of the color management settings for each input socket
of the File Output node individually.

This change will try to add meta data when using a multilayered open
exr file output node in the compositor. It adds the current scene meta
data and converts existing cryptomatte keys so it follows the
naming that is configured in the file output node.
This change supports the basic use-case where the compositor is
used to output cryptomatte layers with a different naming scheme to
support external compositors. In this case the Multilayered OpenEXR
files are used and the meta data is read from the render result.
Meta data is found when render layer node is connected with the
file output node without any other nodes in between. Redirects and empty
node groups are allowed.
The patch has been verified to work with external compositors.

Previously, the span returned by `WriteAttribute`s might not contain the
current value of the attribute for performance reasons. To avoid some
bugs, the span now always contains the old values (they might have to
be copied over from the internal storage, dependending on how the
attribute is stored).
The old behavior is still available with the `get_span_for_write_only`
method. The span that it returns might not contain the current
attribute values. Therefore, it should only be used when you want
to overwrite an attribute without looking at the old values.
When painting using Auto-Normalize or Lock Relative with some
groups locked, the locked weights may not add up precisely to
1 because of precision limitations, which results in creating
nonzero weights close to FLT_EPSILON. With Lock Relative display
mode this is very obvious and annoying (random red points amid
black or blue), so add an epsilon check to consider less than
1e-6 unlocked weight to be the same as 0.
In addition, in cases when no weight can be painted due to locks,
don't create vertex group entries at all if they don't exist yet.
Also, don't run Auto Normalize when not painting a deform group.

* Simplify and clarify logic in `BKE_undosys_step_undo/redo_with_data_ex`,
by adding early return on invalid situations, renaming some variables,
and adding comments.
* Add more sanity checks in those functions.

This patch implements the same operations and interface as the regular
vector math node, but it runs for every element of the attribute. This
should expand what's possible with geometry nodes quite a bit.
Differential Revision: https://developer.blender.org/D9914
Root of the issue is that `BKE_object_eval_boundbox` (that ports back
evaluated bbox to orig object during active depsgraph evaluation) is
only called when object's geometry actually is evaluated.
However, with new undo, often Object itself can be changed by undo,
without requiring its geometry to be re-evaluated, which was leading to
the evaluated bbox not being copied back into orig object anymore.
Fixing that by moving bbox copying-to-orig code into
`BKE_object_sync_to_original` instead, which is always executed when
object is evaluated (as hinted by the comment above
`BKE_object_eval_boundbox` actually).
Also allows to cleanup code for armature eval, apparently.

This can be useful as a workaround on the boundary with the pinned

The `object.collision.use` flag was treated as a redundant marker
of the existence of the modifier, going as far as adding/removing
it when the value was changed, which is not actually very useful.
Removing the modifier loses its position in the stack, and requires
a dependency graph rebuild. It feels it may be a legacy flag?
What would be useful however is the ability to toggle collisions
dynamically without removing the modifier. This patch adjusts the
code to keep the modifier when the flag is disabled, and add it
if it doesn't exist when the flag is enabled. The modifier now
checks the flag at the start and quickly exits after cleaning
up stale data. The redesigned setting is exposed in the UI.
Collisions can't be disabled by simply using the modifier enable
flags because the modifier merely saves a snapshot of the mesh at
a certain point of the modifier stack for other objects to use,
and thus has to be able to clear the stale data.

Previous code would not generate a session uuid for embedded IDs (like
root node trees or master collections). While this is not a problem
currently since those are not directly stored in Main data-base, this is
conceptually wrong, since those IDs still pertain the Main data.
Further more, this is blocking using `session_uuid` more in depsgraph in
place from ID pointer itself, as identifier (related to T84397).
No ID (even remotely) related to Main database should ever be created
directly through MEM_mallocN. Using `BKE_libblock_alloc` is the bare
minimum.
Note that there is no behavior change expected here.
Previously, it was only forbidden to delete the last scene. This can
lead to the situation where a .blend file only contains linked scenes.
This is problematic, because linked data might not always be available
or can be removed from a .blend file without having an additional check
for remaining scenes.
Now there always has to be at least one local scene.

Currently such triangles are effectively already excluded, because
the calculated forces are not applied to pinned vertices. However
these forces are still being computed, which is inefficient.
This adds an early check for triangles where all vertices are
pinned during BVH overlap detection, which significantly speeds
up certain use cases with big fully pinned areas that happen to
overlap a collider. In case of self collision both triangles must
be fully pinned to exclude safely, because the computation is
symmetric and handles two triangles at the same time.

Instances are created with an "index" parameter used for persistence over
time through animation. Currently the geometry nodes instancer passes
the index in the array for this value, but the arrays created by the
"Point Distribution" node aren't necessarily stable in this way when
the input mesh is deformed. In D9832 we already mostly solved this
problem with an `id` attribute. The solution here is to create instances
with this attribute as well.
It's important to note that deforming the instanced points *after*
distribution will usually be a better solution for this problem. This
solution is likely still important though.

'Caused'/revealed by rBd29a720c45e5: Operators that fully re-create the
mesh would previously rely on `sculpt_update_object` called from update
code to get required sculpt-specific data layers re-added to the new
mesh.
Now instead put all code adding data to orig mesh for sculpt purpose
into a new util function (`BKE_sculpt_ensure_orig_mesh_data`), and call
that function when entering sculpt mode, and from voxel remesher code.
This is contonuing effort to more clearly separate orig data from evaluated
data handling/usage in sculpt code.
TODO: there are likely other code paths that would need to call that
new function?

Rename it to mark it is only for `encode` callbacks, fix `encode`
callback of text undo to early fail in case it gets a NULL context, add
an assert to `BKE_undosys_step_push_with_type` that context is not NULL
when undotype requires a valid one.
Note that in practice this should not change anything, currently it
seems that we always get a valid context in
`BKE_undosys_step_push_with_type`?
This was caused when the BKE_pbvh_draw_cb function was used with
update_only_visible set to false. In that case, all nodes with the flag
were updating, but the update flag was only cleared for visible nodes.
This was causing constant updates per redraw in no visible nodes until
they enter the view frustum and their flag was cleared.
In order to fix this and prevent it from happening again:
- Updating the buffers, flushing the updates and clearing the flags are
now part of the same function. It does not make sense to do these in
separate places.
- The BKE_pbvh_draw_cb function was refactored so the
pbvh_update_draw_buffers is only called once. It should now be easier to
understand what the function does when it is used to update only visible
nodes or all nodes.

Use the BMesh symmetrize operator instead of using the modifier code.
While we could support shape-keys with the existing code used by the
mirror modifier, we'd need to add code-paths for evaluated mesh & bmesh
conversion to handle shape-keys differently just for this one case,
since we want to avoid copying & processing shape-keys layers for
evaluated meshes in general.
In the report, the geometry is copied because it has two users and the
final join node needs to write to it. The join node also happens to
remove attributes apparently, because it exposed a mistake in the "copy"
method of the `MeshComponent` class. The copy is supposed to be
a deep copy, but the vertex group name map was not duplicated.

This was introduced in rBe5c0d4613a8943c712b57fb336997ecd78e6508e.
The issue is that the new fluid system does not use the pointcache
system for caching anymore, but still relies on pointcache for
other things. For example, it uses DEG_add_collision_relations
which internally creates relations with pointcache. Not sure if
there are other issues.
Ideally, this dependence should be resolved in one way or another
at some point, but that is out of scope for this fix.
