These features are complicated to support on GPU and hardly compatible
with subdivision in the first place. In the future, with T68891 and
T68893, subdivision and custom smooth shading will be separate workflows.
For now, and to better prepare for this future (although long term
plan), we should discourage workflows mixing subdivision and custom
smooth normals, and as such, this disables GPU subdivision when
autosmoothing or custom split normals are used.
This also adds a message in the modifier's UI to indicate that GPU
subdivision will be disabled if autosmooth or custom split normals are
used on the mesh.

Reuse the same vertex normals calculation as for the GPU code, by
weighing each vertex normals by the angle of the edges incident to the
vertex on the face.
Additionally, remove limit normals, as the CPU code does not use them
either, and would also cause different shading issues when limit surface
is used.
Fixes T95242: shade smooth artifacts with edge crease and limit surface
Fixes T94919: subdivision, different shading between CPU and GPU
The custom data code checks for `LayerTypeInfo.defaultname` before
adding a second layer with a certain type. This was missed in
e7912dfa19. In practice, this default name
is not actually used.
Added call to ensure that the USD plugins are registered
when opening a USD cache archive. This is to avoid USD
load errors due to missing USD file format plugins when
opening blender files that contain USD transform cache
constraints and mesh sequence cache modifilers.
Fixes T94396
This operation can only be applied on one ID at a time, so only apply it
to the active Outliner item, and not all the selected ones.
Also renamed `Make Library Override` menu entry to `Make Library Override
Single` to emphasis this is not the 'default expected' option for the
user.
This affects essentially the Outliner 'create hierarchy' tool currenlty.
Previously code did not handle properly hierarchy root in case overrides
where created from a non-root ID (e.g. an object inside of a linked
collection), and in case additional partial overrides were added to an
existing partially overrided hierarchy.
Also did some renaming on the go to avoid using 'reference' in override
context for anything else but the reference linked IDs.
Trust user count to actually delete or not the dragged ID when current
dragging is cancelled, since it may be already used by others.
NOTE: This is more a band-aid fix than anything else, cancelling drag
has a lot of other issues here (like never deleting any indirectly
linked/appended data, etc.). It needs a proper rethink in general.
To keep consistency with the new contract option, the dilate now expand the shape beyond the internal closed area.
Note: This was committed only in master (3.2) by error.
This is requested by artist for some animation styles where is necessary to fill the area, but create a gap between fill and stroke.
Also some code cleanup and fix a bug in dilate for top area.

Using flags makes checking multiple modifiers at once more convenient
and avoids macros/functions such as IS_EVENT_MOD & WM_event_modifier_flag
which have been removed. It also simplifies checking if modifier keys
have changed.
This means textures need to have the number of mipmap levels specified
upfront. It does not mean the data is immutable.
There is fallback code for OpenGL < 4.2.
Immutable storage will enables texture views in the future.
Without ray offsets intersections at neigbhoring triangles are found, as
the ray start is exactly at the vertex. There was a small offset towards
the center of the triangle, but not enough.
Now this offset computation is moved into Cycles and modified for better
results. It's still not perfect though like any offset approach, especially
with long thin triangles.
Additionaly, this uses the shadow terminate offset for AO rays now, which
helps remove some pre-existing artifacts.
This is similar to f8fe0e831e, which made the change to the
handle position attributes. This commit removes the way that setting the
`position` attribute also changes the handle position attributes. Now,
the "Set Position" node still has this behavior, but changing the
attribute directly (with the modifier's output attributes) does not.
The previous behavior was a relic of the geometry nodes design
from before fields and the set position node existed.
This makes the transition to the new curves data structure simpler.
There is more room for optimizing the Bezier case of the set position
node in the future.
Also fix a couple other places where normals layers weren't properly
tagged dirty or reallocated when the mesh changes.
Caused by cfa53e0fbe. When the size of a mesh changes,
the normal layers need to be reallocated. There were a couple of places
that cleared other runtime data with `BKE_mesh_runtime_clear_geometry`
but didn't deal with normals properly. Clearing the runtime "geometry"
is different from clearing the normals, because sometimes the size of
the normal layers doesn't have to change, in which case simply tagging
them dirty is fine.
Reverts 6d97fdc37e. A function like this should not return a different
tree-display object than of the requested type. This may hide errors,
and leaves the Outliner in an undefined state (where the stored display
mode doesn't match the tree-display object). I rather don't hide the
fact that all display-modes should be handled here, and emit a clear
error if one isn't.
When X-ray mode is active the selection is done using the mesh data to
select what is closest to the cursor. When GPU subdivision is active with
the "show on cage" modifier option, this fails as the mesh used for selection
is the unsubdivided one.
This creates a subdivision wrapper before running the selection routines to
ensure that subdivision is available on the CPU side as well.

This was a double free error which happened because `BM_mesh_bm_from_me`
was taking ownership of arrays that were still owned by the Mesh. Note that
this only happens when the mesh is empty but some custom data layers still
have a non-null data pointer. While usually the data pointer should be null in
this case for performance reasons, other functions should still be able to
handle this situation.
