Audaspace: porting PulseAudio fixes from upstream.

Alembic procedural: remove Generated attribute creation

The main reason for this is to speed up updates by avoid unnecessary
copies as the Generated coordinates are a copy of the vertices.

Creating this attribute may become optional in the future, with UI
parameters to select which attribute to use from the Alembic archive as
reference.

Cycles: use object coordinates when generated coordinates are missing

This modifies the attribute lookup to use object coordinates if no
generated coordinates are found on the geometry.

This is useful to avoid creating and copying this attribute, thus saving
a bit of time and memory.

Cycles: avoid copying vertex normals attribute twice to the devices

Vertex normals are needed for normals maps and therefore are packed and send
to the device alongside the other float3 attributes. However, we already pack
and send vertex normals through `DeviceScene.tri_vnormal`.

This removes the packing of vertex normals from the attributes buffer, and
reuses `tri_vnormal` in the kernel for normals lookup for normal maps, which
reduces memory usage a bit, and speeds up device updates.

This also fixes potential missing normals updates following rB12a06292af86,
since the need for vertex normals for normals maps was overlooked.

LibOverride: Tag all embedded IDs RNA opinters as overridable.

Followup to previous commit, rBfffe219bdb8drBfffe219bdb8d

Again this is only for sake of sane ID/overrides managment for now,
the nodetrees themselves are not overridable from user PoV yet.

LibOverride: tweak resync detection code at apply phase.

This code checks whether an ID pointer property of an override does not
match its linked reference when it is expected to do so.

This is a goiod indication that a resync is needed.

Previous code would falsy detect overrides of IDs referencing themselves
as needing a resync, when this is not effectively the case.

LibOverride: Add several missing 'OVERRIDABLE' flags to NodeTrees RNA.

This should be a no-change commit for now, but is required to enable
initial basic support of nodetrees in library override.

NOTE: Proper full support of liboverrides in nodes is yet to be designed
(has UX unresolved issues, since we likely do not want to expose/make
overridable ALL settings of ALL nodes).

LibOverride: Do not report embedded IDs as non-overridable in 'foreach_id' code.

Embedded IDs (root nodetrees, master collection, etc.) pointer itself is
not editable, but their content may be overridden.

LibOverride code is supposed to know how to handle those embedded IDs.

LibOverride: Make nodetree of material overrideable again.

This reverts rB6899dbef77cd and makes the pointer explicitely
processable by override & diffing code.

Previous changes & fixes have fixed the 'driver-workaround' case afaict.

Note that this only enables proper generic handling of overrides and
their ID pointers, no node property is actually overridable currently.

Geometry Nodes: Add shader Color Mix node

Port color mix shader node to Geometry Nodes.

Fix T90737: VSE adding nested strips could have non-unique names

Caused by {rBbbb1936411a5}.

When adding strips via the new SEQ_add_XXX_strip functions, the
`Editing->seqbasep` pointer was passed around.
Following in `seq_add_generic_update` this `seqbasep` pointer was used
to ensure a unique name.
But `seqbasep` is the pointer to the current list of seq's being edited
(**which can be limited to the ones within a meta strip**).

We need unique names across all strips though (since these are used for
RNA paths, FCurves as reported), so now use the scene's `Editing-
>seqbase` (**which is the list of the top-most sequences**) instead.

Unfortunately this might have screwed files to a borked state, not sure
if this could easily be fixed...

The object was not deselected as it was expected that it would be

But this activation does not happen in edit mode.

T73434: Improve Weight Paint Overlay Drawing.

Master multiplied the weight paint on top of the rendered image. This
reduced readability.

This patch removes the multiplication for weight painting and adds a
hint of the geometry below the overlay.

UDIM: Support tile sets that do not start at 1001

Removes the artificial requirement that UDIM tile sets start at 1001.
Blender was already capable of handling sparse tile sets (non-contiguous
tiles) so the restriction around starting at 1001 was unnecessary in
general.

This required fixing a few UDIM-related python bugs around manually
updating the `tile_number` field on images as well. See the differential
for details. No script changes are necessary but they will now work,
correctly, in many more cases.

Fix T90695: Lower tile splitting limit for lineart

Lowers tile splitting limit so models with extremely dense mesh
portions could still have reasonable performance while for more
common cases the performance impact should be minimal.

Fix wireframe overlay not blending over paint overlay correctly

When using wireframe opacity, the paint overlay needs to be drawn
before the wireframes in order to alpha blend correctly.
Sculpt overlays were also affected by this, so this commit refactors
this part of the code in case other overlays needs to be added in
the future.

Cleanup: move 'recalcData' to 'transform_convert.h'

The `recalcData` function is defined in `transform_convert.c`, so the
header is most expected to be `transform_convert.h`.

GPencil: Fix unreported switch direction not flipping weights

There was an unreported bug that switch direction would not switch the order of the vertex group weights. This caused join to do it wrong as well.

Changed to use `BLI_array_reverse` function here to reverse both the normal points and the weights, therefore simplifying the code.

Fix T82336: Cycles standard attributes missing in displacement shaders

Standard attributes are not added to the attributes requests when
shaders only have displacement. This is because nodes are only
considering the case when the surface socket is connected.

To support this, added `Shader.has_surface_link()` which checks for both
cases (`has_surface` and `has_displacement`) and replaces all checks on
`Shader.has_surface`.
