Callbacks in IDTypeInfo should never affect other IDs if they are not
embedded.
We break this rule in some cases, at least each of those should be
clearly commented about and get some security checks to try to avoid
unexpected issues as much as possible.
Mixing testing and actual action in a single function is just not a good
way to do things, and the 'testing' feature is not used anywhere
anymore, time to get rid of it.
This flag became a full duplicate of `IDTYPE_FLAGS_NO_LIBLINKING`, which
is a good thing (don't think we ever want to be able to link some data,
without being able to make it local...).
So we can now remove it and use `IDTYPE_FLAGS_NO_LIBLINKING` instead.
This moved the spline reversing logic out of the Curve Reverse geometry
node and into the spline class. This allows a spline to reverse itself
with a call to `my_spline.reverse()`
The base class will reverse position, radii & tilt, while specialized
versions are created for Bezier and Nurbs splines to reverse the
additional data that these classes encapsulate.

Essentially, Workspace (and Screen) types were defined as not
localizable.
In previous code it happended to work by mere chance (code path taken in
`BKE_library_make_local` was conviniently skipping the call to
`BKE_lib_id_make_local` in that case, hence not checking for
`IDTYPE_FLAGS_NO_MAKELOCAL` flag of the localized ID type).
This is a total abuse of this IDType flag, for now removing it.
That specific case (IDtype appendable but nor linkable) requires its own
proper flag, this will be tackled in a later commit.
Issue introduced in rB3be5ce4aad5e.
This commit moves the old material nodes to a "legacy" folder and adds
versions of the nodes that work with fields.
The "Select by Material" node is a field node now, so it doesn't have
a geometry output. This is an improvement because there are fewer links
to connect, and it's more easily usable in different situations.
It's also called "Material Selection", since it's more of an input
than an action now.
It's sometimes necessary to use the attribute capture node to get a
more predictable interpolation to mesh faces. This is because the
selection field input is always evaluated on the face domain, so
attribute inputs are interpolated before they are booleans, so they
cannot use the new interpolations from rB5841f8656d9580d7b9.
Differential Revision: https://developer.blender.org/D12456
The generic domain interpolation algorithms didn't quite work for
selections. The interpolation would do unexpected things that
were different than the results in edit mode. The new behavior
is supposed to be the same as edit mode, although we also have
to handle face corner selections here.
Currently the code assumes that all boolean attributes should be
handled that way. I'm not sure of why that wouldn't be the case,
but if we ever need non-selection boolean attributes, that could
be supported too.

Previously, a debug name had to be passed to all methods
that added a resource to the `ResourceScope`. The idea was
that this would make it easier to find certain bugs. In reality
I never found this to be useful, and it was mostly annoying.
The thing is, something that is in a resource scope never leaks
(unless the resource scope is not destructed of course).
Removing the name parameter makes the structure easier to use.
Curve Points of handle of type `Auto` on curves not uniformly scaled

Introduced `BKE_packedfile_unpack` that is called from the specialized
implementation for Image, Sound, Font, Volume etc. This is in
preparation for T91252.
With this commit, curve objects support the geometry nodes modifier.
Curves objects now evaluate to `CurveEval` unless there was a previous
implicit conversion (tessellating modifiers, mesh modifiers, or the
settings in the curve "Geometry" panel). In the new code, curves are
only considered to be the wire edges-- any generated surface is a mesh
instead, stored in the evaluated geometry set.
The consolidation of concepts mentioned above allows remove a lot of
code that had to do with maintaining the `DispList` type temporarily
for modifiers and rendering. Instead, render engines see a separate
object for the mesh from the mesh geometry component, and when the
curve object evaluates to a curve, the `CurveEval` is always used for
drawing wire edges.
However, currently the `DispList` type is still maintained and used as
an intermediate step in implicit mesh conversion. In the future, more
uses of it could be changed to use `CurveEval` and `Mesh` instead.
This is mostly not changed behavior, it is just a formalization of
existing logic after recent fixes for 2.8 versions last year and two
years ago. Also, in the future more functionality can be converted
to nodes, removing cases of implicit conversions. For more discussion
on that topic, see T89676.
The `use_fill_deform` option is removed. It has not worked properly
since 2.62, and the choice for filling a curve before or after
deformation will work much better and be clearer with a node system.
Applying the geometry nodes modifier to generate a curve is not
implemented with this commit, so applying the modifier won't work
at all. This is a separate technical challenge, and should be solved
in a separate step.

Since fields were committed to master, socket inspection did
not work correctly for all socket types anymore. Now the same
functionality as before is back. Furthermore, fields that depend
on some input will now show the inputs in the socket inspection.
I added support for evaluating constant fields more immediately.
This has the benefit that the same constant field is not evaluated
more than once. It also helps with making the field independent
of the multi-functions that it uses. We might still want to change
the ownership handling for the multi-functions of nodes a bit,
but that can be done separately.

Recently we have decided to avoid fancier versioning for nodes with
string inputs for attribute names when updating the attribute workflow
for 3.0. In that case we would just duplicate any node that will
have an updated version to work with fields.
We want to be able to use the "proper" ID names for the new versions
of the nodes though, so this patch adds "Legacy" to the IDs of all
nodes that will be replaced in 3.0. This commit also removes the nodes
from the add menu when the fields experimental preference is enabled,
in order to make it clear what has been updated and what hasn't.
Nodes in the "Maybe" categories in versioning_300.c can be renamed
later if necessary. For now it's probably better to be conservative,
and to keep the list complete.

Previously fluid simulation and Alembic modifiers had a dedicated function
to query the velocity for motion blur. Now use a more generic system where
those modifiers output a velocity attribute.
Advantages:
* Geometry and particle nodes can output velocity through the same mechanism,
or read the attribute coming from earlier modifiers.
* The velocity can be preserved through modifiers like subdivision surface or
auto smooth.
* USD and Alembic previously only output velocity from fluid simulation, now
they work with velocity from other sources too.
* Simplifies the code for renderers like Cycles and exporters like
Alembic and USD.
This breaks compatibility:
* External renderers and exporters accessing these velocities through the
Python API now need to use the attribute instead.
* Existing modifier node setups that create an attribute named "velocity"
will render differently with motion blur.

This implements the initial core framework for fields and anonymous
attributes (also see T91274).
The new functionality is hidden behind the "Geometry Nodes Fields"
feature flag. When enabled in the user preferences, the following
new nodes become available: `Position`, `Index`, `Normal`,
`Set Position` and `Attribute Capture`.
Socket inspection has not been updated to work with fields yet.
Besides these changes at the user level, this patch contains the
ground work for:
* building and evaluating fields at run-time (`FN_fields.hh`) and
* creating and accessing anonymous attributes on geometry
(`BKE_anonymous_attribute.h`).
For evaluating fields we use a new so called multi-function procedure
(`FN_multi_function_procedure.hh`). It allows composing multi-functions
in arbitrary ways and supports efficient evaluation as is required by
fields. See `FN_multi_function_procedure.hh` for more details on how
this evaluation mechanism can be used.
A new `AttributeIDRef` has been added which allows handling named
and anonymous attributes in the same way in many places.

Improve texture painting/uv editing performance when limited scale is active.
Cause of the slow down is that the image editor draws the image in maximum resolution,
but the 3d viewport uses the limited scale. The variation reuses the same GPU texture
and needed to be uploaded/scaled twice to the GPU.
This patch will adds texture slots that can hold the scaled down and the maximum
resolution image. This would allow better cache hits and reuse of existing caches.
Maximum resolution textures are reused for limited scale when they fit to reduce memory
and CPU footprint.

This is to be used when calling code already knows whether the 'made

Currently unused , this is preparation for rewrite of append code.
Previously, the Point Instance node in geometry nodes could only instance
existing objects or collections. The reason was that large parts of Blender
worked under the assumption that objects are the main unit of instancing.
Now we also want to instance geometry within an object, so a slightly larger
refactor was necessary.
This should not affect files that do not use the new kind of instances.
The main change is a redefinition of what "instanced data" is. Now, an
instances is a cow-object + object-data (the geometry). This can be nicely
seen in `struct DupliObject`. This allows the same object to generate
multiple geometries of different types which can be instanced individually.
A nice side effect of this refactor is that having multiple geometry components
is not a special case in the depsgraph object iterator anymore, because those
components are integrated with the `DupliObject` system.
Unfortunately, different systems that work with instances in Blender (e.g.
render engines and exporters) often work under the assumption that objects are
the main unit of instancing. So those have to be updated as well to be able to
handle the new instances. This patch updates Cycles, EEVEE and other viewport
engines. Exporters have not been updated yet. Some minimal (not master-ready)
changes to update the obj and alembic exporters can be found in P2336 and P2335.
Different file formats may want to handle these new instances in different ways.
For users, the only thing that changed is that the Point Instance node now
has a geometry mode.
This also fixes T88454.
