Draw thumbnails as strip overlay. This works for movie and image strips.
To draw thumbnails, this overlay has to be enabled and strips must be
tall enough.
The thumbnails are loaded from source file using separate thread and
stored in cache.
Drawing code uses only images stored in cache, and if any is missing,
background rendering job is started. If job can not render thumbnail,
to prevent endless loop of creating job for missing image it sets
`SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag.
To prevent visual glitches during timeline panning and zooming, `View2D`
flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code
will look for set of evenly distributed thumbnails that should be
guaranteed to exist and also set of previously displayed thumbnails.
Due to volatile nature of cache these thumbnails can be missing anyway,
in which case no new thumbnails will be drawn for particular strip.
Cache capacity is limited to 5000 thumbnails and performs cleanup of
non visible images when limit is reached.

This is used to find a valid collection in which to instantiate stray
objects and collections.
In some cases there will be no such active view layer, in which case we
can consider using the Scene's master collections children hierarchy
instead to find a valid instantiated parent collection for those stray
data.
This node allows sampling positions, tangents, and normals at any
arbitrary point along a curve. The curve can include multiple splines,
all are taken into account. The node does not yet support transferring
generic attributes like radius, because some more general tooling will
make that much more feasible and useful in different scenarios.
This is a field node, so it is evaluated in the context of a data-flow
node like "Set Position". One nice thing about that is it can easily
be used to move an entire geometry like the follow path constraint.
The point along the curve is chosen either with a factor of the total
length of the curve, or a length into the curve, the same choice used
in the curve trim node.

This nodes evaluates a field on a geometry and outputs various
statistics about the entire data set, like min, max, or even
the standard deviation. It works for float and vector types currently,
though more types could be supported in the future.
- All statistics are calculated element-wise for vectors.
- "Product" was not added since the result could very easily overflow.
- The "Size" output was not added since it isn't specific to an
attribute and would fit better in another node.
The implementation shares work as much as possible when multiple
statistics are needed.
This node has been in development since the beginning of this year,
with additions from Johnny Matthews and Hans Goudey.

Previously, the node would always realize instances implicitly.
Now it can change the position of entire instances.
The Realize Instances node can be used before if the old
behavior is required.
Differential Revision: https://developer.blender.org/D12555
This node has a simple geometry input and output.
If the input geometry contains instances, they will be realized
into actual geometry. When there are many instances, this can
be very slow and memory intensive. Generally, instances should
only be made real when necessary, e.g. when every instance
should be deformed independently.

The case that checked whether there were evaluated edges was incorrect,
since two points are needed for an edge. Then also avoid running the

When using FModifier `Restrict Frame Range`, the resulting influence was
zero being exactly on `Start` / `End` range borders (so borders were
**exclusive**).
This made it impossible to chain FModifers together (forcing the user to
specify values slightly below the desired border in following
FModifiers).
This is now corrected to be **inclusive** on Start / End range borders.

In the case of touching open borders (so [frame A frame B] followed by
[frame B frame C]) both modifiers are evaluated (in stack order).
If the later modifier has full influence (and is not additive) this simply
means the result is the same as the later modifier's value.
If influences below 1 are used (or modifiers are additive) both modifier's
values are interpolated/added accordingly.
technical notes:
- this was caused by the introduction of FModifier Influence/BlendIn-Out
in rB185663b52b61.
- for comparison, see other occurrences of
`FMODIFIER_FLAG_RANGERESTRICT`.
- the following conditions in `eval_fmodifier_influence` for blend in/
out have been changed accordingly.

This adds a toggle to node group inputs exposed in the modifier to use
an attribute instead of a single value. When the toggle is pressed, the
button switches to a text button to choose an attribute name. Attribute
search isn't implemented here yet.
One confusing thing is that some values can't be driven by attributes
at all, like the size of a primitive node. In that case, we should have
a node warning, but that will be separate since it's more general.
We can also have an option to turn off this toggle in node group
input settings.
The two new properties for each input are stored with the same name
as the value, but with `"_use_attribute"` and `"_attribute_name"``
suffixes. The properties are not added for socket types that don't
support attribute input, like object sockets.

Store the optional temporary span storage as a unique_ptr and move
it in the move constructor, to avoid the need to add a special move
constructor that clears the "show_warning" fields from it. Maybe this
is very slightly slower, but we'll need this class less often in the future
anyway.
Add needed extra flag and utils to IDType to mark and check an ID type
as only appendable.
Note that this is only a loose user-level enforcement currently, in any
case you need to be able to link an ID to append it currently, so for
low-level code this does not really matter.
Currently only WorkSpace and Screen ID types are marked with the new
`IDTYPE_FLAGS_ONLY_APPEND` flag.
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.

Current `BKE_libblock_relink_to_newid` is using its own simplistic,
limited and not really correct version of ID remapping.
While doing a full replacement would have been ideal, this is
risky/time-constrained for Blender 3.0 release, so for now we'll have
both versions co-existing.
Previously, it was necessary to rebuild the node declaration
every time it was used. Now it is cached per node for easy
and fast access.

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.
