Remove the selection attributes on the non-selected domains, since they
will be automatically filled by domain interopolation anyway. Arguably
this should be fixed in a more general way, either by ensuring they are
always on the expected domains or more gracefully handling the case
when they aren't at a lower level. But for this node, for now this is
a simpler approach.
Updated CacheReader_open_usd_object() to issue a warning and
return early if the given object path does not refer to a
valid prim on the USD stage, to avoid crashing when attempting
to create a reader from an invalid prim.

Caused by 6a49041be3 .
Above commit checks an existing nameproperty for collection items, but
it does so in a way that it only checks the "parent" type. If these are
"subclassed" though, we might not have the nameproperty defined on the
"parent" class (but on the subclass instead).
Code would then error out with e.g. "FreestyleLineStyle.color_modifiers
does not support string lookups".
In the case of the report the following happened.
- linestyle modifiers (`LineStyleModifier`) can be any of:
-- `color_modifiers` / `LineStyleColorModifier`
-- `alpha_modifiers` / `LineStyleAlphaModifier`
-- `thickness_modifiers` / `LineStyleThicknessModifier`
-- `geometry_modifiers` / `LineStyleGeometryModifier`
But all of the above have subtypes, e.g.
`LineStyleColorModifier_AlongStroke`,
`LineStyleColorModifier_DistanceFromCamera`, ...
Currently, the `nameproperty` is not defined e.g. on the
`LineStyleColorModifier` (but instead on the subtypes).
Prior to 6a49041be3 (without
`RNA_property_collection_lookup_string_has_nameprop` in place),
`pyrna_prop_collection_subscript_str` could still actually find the
nameprop because it iterates into the collection and got it on the
actual Item (`LineStyleColorModifier_DistanceFromCamera` instead of
`LineStyleColorModifier`).
So while it might be possible to refine
`RNA_property_collection_lookup_string_has_nameprop` to descend into
subclasses (I didnt find an obvious way though other than scanning all
existing modifiers [not modifier types -- we would need a way to find
all types that inherit from e.g. `LineStyleColorModifier`] which kind of
defeats the purpose of checking this early), this PR moves the name
definition from the subclass to the parent class (so way from
`rna_def_modifier_type_common`) -- and this way,
`RNA_property_collection_lookup_string_has_nameprop` can properly pick
up the nameprop. It does a bit of code duplication though.

The crash was happening because the storage buffer for active smoothing
was not resized correctly as the active smoothing window changed.
This fix makes sure the storage buffer is resized correctly.
The issue was that custom data layers were modified without checking
that the data was not shared. Now the data is unshared first.
I also added an assert to catches this kind of issue more directly.
Exposed by cba9f47562 (but actually caused by 4d668e6825 I think).
Because of 4d668e6825 , the `StripDrawContext` `content_start` &
`content_end` were wrong for hold still regions.
These wrong extends were then used in cba9f47562 .
Now actually update `StripDrawContext` `content_start` & `content_end`
when hold still regions are in play (instead of just calling the right
functions [but not using their return values]).

Set the "I/O error" if the result from read is larger than the requested
size, while unlikely - set the error so an error return always sets the
`errno`.
Pass the mesh to the drawing functions so it doesn't have to be
retrieved from the PBVH. It's nice to rely less on the PBVH `me`
pointer, since it's a fairly ugly "back pointer" which isn't necessarily
good design.
Making some liboverride local will break/corrupt liboverride hierarchies
in many cases. So that function (or its caller, in some cases) need to
call #BKE_lib_override_library_main_hierarchy_root_ensure to re-validate
(and re-generate if needed) the liboverride hierarchy roots.
The code ensuring a valid liboverride hierarchy root ID pointer for all
liboverrides in a given Main would fail in some cases, and crash on
asserts (in Debug builds) or due to corrupted data later in code
(release builds).
The main issue fixed here is re-entry in case of dependency loops (a
same ID being checked more than once within the same chain of recursive
calls to ensure its hierarchy root is valid). Solved the usual way now,
using the intermediate 'PROCESSING' flag instead of setting immediately
the 'PROCESSED' one, when recursively processing the chain of
dependencies.
A second issue fixed in that code was that in some cases, it could leave
the invalid existing hierarchy root pointer unchanged, because it could
not find a 'valid enough' alternative.
NOTE: This data corruption is presumably caused by 'make local'
operations on liboverride hierarchy root IDs. This will be addressed as
a second commit.
For reference, issue is reproducible when opening
`/promo/splash/040_0010.lighting.splash.blend` from Pets SVN repo r3106.
This implements the core changes for this design: https://devtalk.blender.org/t/grease-pencil-integration-into-geometry-nodes/31220
The changes include:
* Add `CustomData` for layer attributes
* Add attribute support for the `GreasePencilComponent` to read/write layer attributes. Also introduces a `Layer` domain.
* Implement a `GreasePencilLayerFieldContext` and make `GeometryFieldContext` work with grease pencil layers.
* Implement `Set Position` node for `Grease Pencil`.
Note: These changes are only accessible/visible with the `Grease Pencil 3.0` experimental flag enabled.
