During a mesh transformation in edit mode (Move, Rotate...), only part of
the batch cache needs to be updated.
This commit allows only update only the drawn batches seen in
`BKE_object_data_eval_batch_cache_deform_tag` if the new
`ID_RECALC_GEOMETRY_DEFORM` flag is used.
This new flag is used in the transforms operation for edit-mesh and
results in 1.6x overall speedup in heavy subdiv cube.

Delay depsgraph visibility update tagging until it is known that
graph relations are up to date, and until it is known that the graph
is actually needed to be evaluated.

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.
There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.
Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading
Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.
Patch implemented by Sergey and me.

Under some circumstances using task isolation can cause deadlocks.
Previously, our task pool implementation would run all tasks in an
isolated region. Now using task isolation is optional and can be
turned on/off for individual task pools.
Task pools that spawn new tasks recursively should never enable
task isolation. There is a new check that finds these cases at runtime.
Right now this check is disabled, so that this commit is a pure refactor.
It will be enabled in an upcoming commit.
This fixes T88598.

Share the pointer with the original mesh instead, this matches behavior
of all other objects edit-mode data.
Duplicating the edit-mesh pointer makes updates to edit-mesh require
a COPY_ON_WRITE update, which is currently an expensive operation
(copying the entire mesh).
Notes:
- This change is from 802027f3f8
so the edit-meshes object pointer `BMEditMesh.ob` referenced the COW
version of the object. This pointer has since been removed, so the
copy is no longer needed.
- Having a separate edit-mesh pointer could be used so linked duplicates
could have their own generated meshes. For this to be supported,
many other changes would be needed: see D10920.
Resolve ownership ambiguity with shared physics pointers.
Previously, LIB_ID_CREATE_NO_MAIN allowed pointer sharing with
the source ID so physics caches can be shared between original and
evaluated data: (Object.soft.shared & Object.rigidbody_object.shared).
This only worked properly for LIB_TAG_COPIED_ON_WRITE ID's,
as LIB_TAG_NO_MAIN can be used in situations where the original ID's
lifetime limited by it's original data.
This commit adds `LIB_ID_COPY_SET_COPIED_ON_WRITE` so ID's only share
memory with original data for ID's evaluated in the depsgraph.
For all other uses, a full copy of physics data is made.

Fix `nullptr` redeference when setting 'orig_data' pointers on CoW copies,
by stopping the loop also when `element_cow == nullptr`. This avoids a
crash of Blender when the original list of pointers is longer than the
CoW list of pointers.
I've also added a `BLI_assert()` that checks for equal lengths of the
two `ListBase`s, so that problems like these aren't hidden away completely.
The root cause of the crash was actually a modifier that was assigned to
an object of the wrong type (an Armature object doesn't support modifiers).
This caused the list of modifiers on the CoW copy to be shorter than the
list of modifiers on the original Object. It's still a mystery how that
object got that modifier in the first place.
This removes a lot of unnecessary code that is generated by
the compiler automatically.
In very few cases, a defaulted destructor in a .cc file is
still necessary, because of forward declarations in the header.
I removed some defaulted virtual destructors, because they are not
necessary, when the parent class has a virtual destructor already.
Defaulted constructors are only necessary when there is another
constructor, but the class should still be default constructible.

Handle Lattice object the same way as Mesh objects. This is mostly to
execute the `object->data = data_eval;` line, which ensures that the
evaluated mesh is assigned to the evaluated object, and thus prevents
the lattice from un-deforming.
Rename:
- `BKE_animsys_store_rna_setting` → `BKE_animsys_rna_path_resolve`
- `BKE_animsys_read_rna_setting` → `BKE_animsys_read_from_rna_path`
- `BKE_animsys_write_rna_setting` → `BKE_animsys_write_to_rna_path`
The concept of "RNA setting" is unclear; the new names reflect better
what the functions actually do.
No functional changes.
Corrects incorrect usage of contraction for 'it is', when possessive 'its' was required.

Note that possibility to pass the new ID pointer as parameter was kept,
as this is needed for some rather specific cases (like in depsgraph/COW,
when copying into already allocated memory).
Part of T71219.
This reverts {rB1693a5efe91999b60b3dc0bdff727473b3bd00bb}
and implements an alternative solution.
The old patch had the problem that the depsgraph would always
evaluate at the current frame of the original scene (even when
`DEG_evaluate_on_framechange` was used). Now it is possible
to evaluate the depsgraph at a specific frame without having to
change the original scene.

Solves possible pointer-based comparison fiasco.
Another nice outcome of this is that topology cache will now be
preserved throughout the undo system. For example, undo of object
transform will not require topology cache to be re-created.
Differential Revision: https://developer.blender.org/D8493
The root of the issue comes to the fact that sub-data pointers were
used to match strips before/after copy-on-write. The undo system might
re-use sub-data pointers after re-allocating them, making it so that,
for example, pointer used by sound strip is later re-used by video
strip.
This fix takes an advantage of recently introduced per-sequence UUID
and uses it to match sequences before/after copy-on-write.
Will trigger code paths which makes sure UUIDs are generated and
are unique.
Enabled with --debug-depsgraph-uuid (which is also implied by
--debug-depsgraph).
A simulation data block has an embedded node tree, which requires
special handling in a couple of places. Some of those places were
missing beforehand.
This also adds a relation to make sure that the simulation is evaluated
after animations on the embedded node tree are evaluated.
This updates the usage of integer types in code I wrote according to our new style guides.
Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).
I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.
Every Particle Simulation node has a name (or a path when it is in a node group).
This name has to be used in the Simulation modifier on a point cloud to see
the particles.
Caching has been disabled for now, because it was holding back development
a bit. To reset the simulation, go back to frame 1.
Currently, there is no way to influence the simulation. There are just some
randomly moving points. Changing that is the next step.
