Semantically it is more correct as the cache does not modify the ID.
There is need to do couple of const casts since the BKE (which is in C)
does not easily allow to iterate into f-curves of const ID.
Should be no functional changes.
This is useful when using an armature as a camera rig, to avoid creating and
targetting an empty object.

Even if the driver is not dependent on time the modifiers were always
re-evaluated during playback. This is due to the legacy nature of the
check whether modifier depends on time or not: it was simply checking
for sub-string match for modifier in the F-Curve and drivers RNA paths.
Nowadays such dependencies are created by the dependency graph builder,
which allows to have more granular control over what depends on what.
The code is now simplified to only check for "static" dependency of the
modifier form time: for example, Wave modifier which always depends on
time (even without explicit animation involved).
This change also fixes missing relation from the animation component to
the shader_fx modifiers, fixing race condition.
Additional files used to verify relations:
- Geometry: F13257368
- Grease Pencil: F13257369
- Shader FX: F13257370
In these files different types of modifiers have an animated property,
and the purpose of the test is to verify that the modifiers do react
to the animation and that there is a relation between animation and
geometry components of the object. The latter one can only be checked
using the dependency graph relation visualization.
The drivers are not tested by these files. Those are not typically
depend on time, and if there were missing relation from driver to
the modifier we'd receive a bug report already. As well as if there
was a bug in missing time relation to a driver we'd also receive a
report.

Active camera is a property of Scene, so need to take scene changes into
account for such drivers to work reliably.
The fix covers all the common cases of such configurations, but some of
them might not be yet fully supported. Mainly cases when the target ID
is not covered by the copy-on-write mechanism.
There is a fuller explanation available in the code for the ease of reading

Instead of directly accessing constraint-specific callbacks
in code all over blender, introduce two wrappers to retrieve
and free the target list.
This incidentally revealed a place within the Collada exporter
in BCAnimationSampler.cpp that didn't clean up after retrieving
the targets, resulting in a small memory leak. Fixing this should
be the only functional change in this commit.
This was split off from D9732.

`bNodeTree` has a lot of run-time embedded in it currently. Having a separately
allocated run-time struct has some benefits:
* Run-time data is not stored in files.
* Makes it easy to use c++ types as run-time data.
* More clear distinction between what data only exists at run-time and which doesn't.
This commit doesn't move all run-time data to the new struct yet, only the data where
I know for sure how it is used. The remaining data can be moved separately.

This is a regression caused by a230445cae.
The internal cause of the issue was that the synchronization component
was no longer tagged as visible (and hence not evaluated) as it not
connected to any directly visible IDs.
Changed the logic in a way that if any component of an ID is evaluated
the synchronization component will be evaluated as well.
The naming of the flag in the component node is a bit confusing, but
for the simplicity of the change for the upcoming release left it
unchanged.
The goal is to make it easier to track down sources of errors during
the dependency graph builder.
With this change whenever a relation can not be added a trace to the
entity which requested the relation will be printed. For example:
```
Failed to add relation "Copy Location"
Could not find op_from: OperationKey(type: BONE, component name: 'MissingBone', operation code: BONE_DONE)
Trace:
Depth Type Name
----- ---- ----
1 Object Armature.001
2 Pose Channel Bone
3 Constraint Copy Location
```
On an implementation detail traced places where `checkIsBuiltAndTag`
is called, with some additional places to help tracking pose channels,
constraints, and modifiers.
Further improvements in granularity are possible, but that could happen
as a followup development once the core part is proven to work.
An example of such improvement would be to have entries in the trace
which will indicate NLA and drivers building. Currently it might be
a bit confusing to see IDs in the trace referenced from driver.
Even with such limitation the current state of the patch brings a
very valuable information (some information is much better than no
information at all).

Previously, the depsgraph assumed that every node tree might contain
a reference to a video. This resulted noticeable overhead when there
was no video.
Checking whether a node tree contained a video was relatively expensive
to do in the depsgraph. It is cheaper now due to the structure of the new
node tree updater.
This also adds an additional run-time field to `bNodeTree` (there are
quite a few already). We should move those to a separate run-time
struct, but not as part of a bug fix.

Fix a crash when a driver variable targets an object and uses
`data.shape_keys.key["name"].value` in its expression.
The fix consists of adding an extra relation from the targeted object's
`GEOMETRY` component to the driver evaluation. This ensures that its
`data` pointer has been evaluated by the depsgraph and is safe to
follow.
This also resolves the concern raised on rB56407432a6aa.

Originally was noticed when using a linked background scene and a scene
camera from another (local) scene.
The root issue was that relation from view layer to object's base flags
evaluation was using wrong view layer. This is because the relation was
created between object and currently built view layer, and it only was
happening once (since the object-level relations are only built once).
Depending on order in which `build_object` was called it was possible
that relation from a wrong view layer was used.
Now the code is better split to indicate which parts of object relations
are built when object comes from a base in the view layer, and which ones
are built on indirect linking of object to the dependency graph.
This patch makes relations correct in the cases when the same object is
used as a base in both active and set scenes. But, the operation which
handles object-level flags might not behave correctly as there is no
known design of what is the proper thing to do in this case. Making a
clear design and implementation of case when object is shared between
active and set scene is outside of the scope of this patch.

The Alembic procedural was only enabled during viewport renders
originally because it did not have any caching strategy. Now that
is does, we can allow its usage in final renders.
This also removes the `dag_eval_mode` argument passing to

we are doing a viewport render for enabling the procedural.

Make relation match material and world nodes. Does not address the reported
issue regarding muted nodes, but another missing update found investigating.
This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

The main issue is that the image and image user is not updated correctly
in `rna_ImageUser_update`. `BKE_image_user_frame_calc` does not set the
correct frame, because the image is null. Also `IMA_GPU_REFRESH` is not
set for the same reason.
When gpu materials are first created, it is expected that the frame is set
correctly, and the flag is set if necessary. Therefore, somewhere during
depsgraph evaluation, those have to be updated. The depsgraph node
to do the update existed already. Now there is a new relation so that it is
executed when the node tree changed, not only when the frame changed.
Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

The previous optimization did not work in general yet, unfortunately.
This change makes the code more correct, but also brings back
some unnecessary updates (e.g. when creating a node group).
This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.
I would like to give a huge thanks to @JacquesLucke who helped during this
and pushed me to reduce the duplication further.

The issue was caused by rBd09b1d2759861aa012ab2e7e4ce2ffa2.
Since this commit, the image users in gpu materials were updated
during depsgraph evaluation as well. However, there was a race
condition when one thread is deleting gpu materials in `BKE_material_eval`
while another thread is updating the image users at the same time.
The solution is to make sure that deleting gpu materials is done before
iterating over all gpu materials, by adding a new depsgraph relation.
