Currently overriding properties within material node trees is not
supported. However there is a workaround that allows feeding values
through drivers via an intermediate custom property, as described
in T82404. The workaround relies on the behavior of the ID copying
code that always patches datablock self-references even without any
overrides.
Unfortunately, this broke during development of 2.93. This happened
because a call RNA_struct_override_matches added in rB2281db72b0157
detects that no override exists, and 'restores' the self-reference
to point to the original datablock.
To avoid this, mark the Material.node_tree property with the
PROPOVERRIDE_IGNORE flag to stop RNA_struct_override_matches
from recursing into the currently unsupported node tree sub-block.
This flag should be removed when this is properly supported.
This was confirmed to fix the workaround and discussed with @mont29.
- Re-order freeing so an instances __del__ method runs before the
`ExtensionRNA` has been freed.
- "remove" functions no longer free the gizmo/gizmo-group memory,
needed so the identifier used when freeing the extension
doesn't use the freed identifier.
The `bisect_distance` in the mirror modifier was hard-coded to `0.001`.
This would result in some unexpected behavior like vertices close
to the mirror plane being deleted or merged.
The fix now adds a parameter to the mirror modifier to expose the
bisect distance to the user. The default is set to the previous
hard-coded value to not "change" previous files.

This flag is needed so PointerRNA structs that aren't
part of the current context can access enum values
without inspecting the context.
This is needed for keymap access, so the keymap UI and keymap
export doesn't depend on the current context.
`make lite` does not use audaspace, so some files will pollute the console with
tons of warnings about audio values not defined.

This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

The problem was that you could getting write access to a grid from a
`const Volume *` without breaking const correctness. I encountered this
when working on support for volumes in the bounding box node. For
geometry nodes there is an important distinction between getting data
"for read" and "for write", with the former returning a `const` version
of the data.
Also, for volumes it was necessary to cast away const, since all of
the relevant functions in `volume.cc` didn't have const versions. This
patch adds `const` in these places, distinguising between "for read"
and "for write" versions of functions where necessary.
The downside is that loading and unloading in the global volume cache
needs const write-access to some member variables. I see that as an
inherent problem that comes up with caching that never has a beautiful
solution anyway.
Some of the const-ness could probably be propogated futher in EEVEE
code, but I'll leave that out, since there is another level of caching.

Previously, the spreadsheet editor could only show data of the original

For that the mode has to be set to "Node" in the spreadsheet editor.
Furthermore, the preview of a specific node has to be activated by

It is already very useful for debugging node groups in it's current

The issue was that where_on_path uses a resampled curve to get the data
from the curve. This leads to disconnects between the curve the user
sees and the evaluated location data.
To fix this we simply use the actual curve data the user can see.
The older code needed a cleanup either way as there were hacks in other
parts of the code trying to work around some brokenness. This is now
fixed and we no longer need to clamp the evaluation range to 0-1 or make
helper functions to make it do what we actually want.

Tweaking e.g. a field strength would then not use the curve/surface
normal anymore [but the object center instead].
If a curve has a forcefield with effector shape Curve (in code its shape
is PFIELD_SHAPE_SURFACE then), it wil get a SurfaceModifier.
Changing properties will free the SurfaceModifierData's bvhtree and mesh
And these dont get copied along when doing the CoW copy, these are
explicitly set to NULL. So this was also failing for meshes, not just
curves.
Without the mesh & bvhtree though, get_effector_data() will not set the
EffectorData's normal correctly (it is closest_point_on_surface() which
does this). And without the right EffectorData's normal, the effector
will of course work unexpected.
Going in and out of editmode made this work because that goes down this
route:
- BKE_object_handle_data_update
- BKE_displist_make_curveTypes
- do_makeDispListCurveTypes
- curve_calc_modifiers_post
-- BKE_mesh_new_nomain_from_curve_displist
-- we then have our desired updated mesh from the curve
-- this will also call the SurfaceModifiers deformVerts [which - given we
have a valid mesh - will update the bvhtree properly]
Also note that _animating_ the effector actually works, (have not done
the deep dive why this works, assume the curve geometry is updated in
this case)
So, now just carefully tag the curve ID_RECALC_GEOMETRY in
rna_FieldSettings_update for this specific case.

Reading Area.type & ui_type printed an error from `pyrna_enum_to_py`
and returned an empty string.
As empty is a valid value, include it in the property enum list.
For Cycles, when enabling the Persistent Data option, the full render data
will be preserved from frame-to-frame in animation renders and between
re-renders of the scene. This means that any modifier evaluation, BVH
building, OpenGL vertex buffer uploads, etc, can be done only once for
unchanged objects. This comes at an increased memory cost.
Previously there option was named Persistent Images and had a more limited
impact on render time and memory.
When using multiple view layers, only data from a single view layer is
preserved to keep memory usage somewhat under control. However objects
shared between view layers are preserved, and so this can speedup such
renders as well, even single frame renders.
For Eevee and Workbench this option is not available, however these engines
will now always reuse the depsgraph for animation and multiple view layers.
This can significantly speed up rendering.
These engines do not support sharing the depsgraph between re-renders, due
to technical issues regarding OpenGL contexts. Support for this could be added
if those are solved, see the code comments for details.
Materials used in grease pencil modifiers have the requirement that they
are already used on the object. In the UI dropdown, this restriction is
ensured by calling uiItemPointerR with appropriate searchptr and
searchpropname, so only giving the user the choice of materials already
used on the object.
From python though, it was still possible to assign materials outside of
this this restriction. This led to reports like T86981 [which have been
partially solved by clamping the material index in the modifier code to
be in the valid range].
Now make sure we dont assign "invalid" materials through RNA by
appropriate RNA pointer functions.
This also adds a proper warning (red, alert) in case of the LineArt
modifier if such a invalid material is still in the file [same as other
modifiers already do].

Before this change, you could have the new sculpt symmetry code and the
older weight paint symmetry code active at the same time. This would
lead to users easily trashing their weigh paint data if they were not
careful when switching between modes.
Now the specific weight paint symmetry code is an exclusive toggle so
the user can't accidentally mirror strokes and vertex groups at the same
time. This also paves the way of supporting Y and Z symmetry in the
future for weight groups mirroring if we decide to add it in the future.

This commit improves the performance of the node by up to 40% in some
cases when there are only two input meshes, mainly by skipping the
conversion to and from BMesh.
When there are more than two input meshes (note the distinction from
"Geometries", a geometry set can have many mesh instances), the
performance is actually worse, since boolean currently always does
self intersection in that case. Theoretically this could be improved
in the boolean code, or another option is automatically realizing
instances for each input geometry set.
Another improvement is using multi-input sockets for the inputs, which
removes the need to have a separate boolean node for every operation,
which can hopefully simplify some node trees.
The changes necessary for transforms in `mesh_boolean_convert.cc` are
somewhat subtle; they come from the fact that the collecting the
geometry set instances already gives transforms in the local space
of the modifier object. There is also a very small amount of cleanup
to those lines, using `float4x4::identity()`.
This commit also fixes T87078, where overlapping difference meshes
makes the operation not work, though I haven't investigated why.

This node provides only SMAA 1x mode, so the operation will be done with no spatial

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.

1. The program code assumes the screen coordinates are DirectX style that the
