In some rare cases it is convenient to store a short array value
as a custom property, e.g. a vector or color. For example, it may
be helpful when importing/exporting certain formats that support
custom or nonstandard attributes on objects.
The custom property storage already can handle arrays in order to
support properties defined via python. The only thing missing is
UI support (and some bugs), and this patch fixes that:
- Allow editing short array properties via Custom Properties panel.
- Fix a UI layout sizing bug triggered by the previous item.
- Fix a dependency graph bug with drivers using such properties.
- Make RNA_*_get_default_array code robust in case of size mismatch.
- Support custom default values for array properties, allowing
both an array and a scalar value.

Such reload can no longer happen directly and is to be done via dependency
graph.
Eventually, the movie cache will become shared across all copies of the
clip, but even then we still need to have dependency graph mechanism because
we need to update FFmpeg animation handle (which can not be shared across
the copies).
There are two aspects to the problem:
- Dependency graph update for compositor preview was missing
updates flush.
Apparently, update for new frame style of update will take
care of flushing, but not the update tagged style of update.
This goes to a legacy dependency graph and is to be changed
at some point, but not so close to the release.
- Movie clips were missing from the compositor dependency graph.
This fixes part of T66519.

The root of the issue comes to the fact that part of dependency graph
is being removed, without doing any further remapping.
This was happening because only materials used by objects were pulled
in, so when material mode is changed some material became unused and
removed from the dependency graph and freed, causing object or its
data to point to a freed memory in its materials array.
Simplest and safest way to solve this is to pull materials referenced
by both object and object data. This causes somewhat higher memory
usage but keeps evaluated state of scene in an always consistent state,
without any need to tag/update object's data on material mode change.
Don't think it is a problem in practice.

This change makes it so sound handles are created for evaluated scene,
sequencer and speakers. This allows to have properly evaluated animation
on them.
For the viewport playback sound uses regular dependency graph.
For the final render sound uses dependency graph created for render pipeline,
which now also contains sequencer and sound datablocks.
All the direct sound update calls are replaced with corresponding dependency
graph recalc tag.
This change makes it so a minimal dependency graph which only includes
compositor and sequencer is built for the render pipeline purposes.
Tricky part here is that it's only compositor itself and sequencer who
to use this dependency graph and IDs from it. Render engines are still
to be provided original IDs because:
- They will create dependency graph for the given scene, and currently
it is not possible to create dependency graph from CoW scene.
- IDs from the compositor/sequencer dependency graph are "stripped",
as in, they wouldn't have all view layers, collections or objects
required for proper final render.
This creates annoying mess of mixing evaluated and original scene
access in various parts of the pipeline.

Fixes T61014: Assert adding a driver that uses a single property of a scene ID
Masks were not really covered by Copy-on-Write due to mistake
in the dependency graph. After correcting that mistake a lot
of tools became broken, so majority of the patch is related
on making it so access to evaluated/tessellated masks is done.
When accessing evaluated mask state make sure access to an
evaluated dependency graph is done. This solves possible
access to NULL data on redo.

No major API change here, only in the outliner restriction column
variables (e.g., show_restrict_column_selectable > show_restrict_column_select).
* Get rid of _INSTANCE (introduced on b1af682001).
* Differentiate (everywhere but the API) between HIDE (temporary) and VIEWPORT (global).
* Use the expected icon for restrict viewport (same as objects and modifiers).
* selectable > select
See T61578 for discussions and mockups.
Visibility Options
==================
We are adding more granular control over restriction columns in the outliner,
exposing "indirect only" and "holdout" as options, and change the way
users enable/disable collections in a viewlayer.
We also rename the object viewport restriction to hide instance.
So the options we have are:
Collection
----------
* Render Visibility
* Instance Visibility
* Selectable
(View) Layer Collection
-----------------------
* Enable
* Holdout
* Indirect Only
* Viewport
Shortcuts
=========
Isolate Collection
------------------
* Ctr + click isolates the collection.
It turns all its parents and children "visible", and all the other
collections "invisible".
If ALL the collections were already properly set, we re-set the
collections to their default value.
Set Collection Inside Collections and Objects
---------------------------------------------
* Shift + click: Set/unset inside collections and objects.
We only set objects values as well when we are in View Layer mode and
(obviously) when the objects have a matching property.
Icons
=====
Little reminder that we will need better icons for holdout, indirect only, and
probably instanced (nothing wrong with the current, but it differs from
the proposal when it is turned off).
Also, we need to decide where do we want the modifier/bones/... icons to
be (in which column) and ideally make sure their icons match the ones we
use for collections/objects.
At the moment those are using the screen icon, which is not being used
by collections.

This happened to be a bigger rabbit hole to hell than it originally seemed,
and there are higher priority design tasks to be handled (at this point high
priority design task is more important than high priority bug fix).
After talking to Brecht the decision was made to revert to the known isolated
issue, which will allow everyone in the studio work same as prior to last
Friday.
The remaining bits will be worked on after all the design tasks are out of
the way.

Just adds sequencer operation and links possible sound ID to it.
No functional changes, just moving towards sound system integration
into the dependency graph.
Currently those IDs are not covered by copy-on-write mechanism since
that ruins the current design of BKE_sound, But this change allows to
move towards system where sound handlers are only valid for an evaluated
ID datablocks.
* The cache file datablock is now evaluated as part of the dependency graph,
creating/freeing the Alembic file handle matching the current frame.
Modifiers and constraints depend on this evaluation.
* Cache file handles and readers now only exist on COW datablocks, never the
original ones.
* Object data paths are flushed back to the original for the user interface.
* The cache file keeps a list of all readers associated with its handle, and
automatically frees them when the handle is freed. This kind of sharing of
data across datablocks is weak but we have no better mechanism for it.

Should be no functional changes, just switching code to use more
generic checks now.
One thing which goes a bit deeper than that is check for whether
base is a part of dependency graph. This is now done by explicitly
tagging corresponding ID node (of an object) rather than doing
animation check again.
Allows to speed up lookups like "is property FOO of data BAR animated".
Can be used to optimize object's visibility check, but also allows to
check animation on bones without too much of time penalty.
The cache is shared between both nodes and relations builder.
Currently is not used, just a boilerplate for an upcoming changes in
an actual logic.
There was missing flush from transform update to the point cache
reset. Caused by the fact that when update happens in the "middle"
of component all the component operations will be tagged for update
(since the intermediate state is not stored), but that will not
flush updates to other operations since that would cause too much
of updates.
This now we tag point cache for reset after evaluation operation
but before final transform and before rigid body world.
The issue is a feedback loop with point cache reset operation.
Solved by introducing extra node which ensures object's transformation
is ready for simulator input. Allows to route relations without causing
a fake dependency cycle now.
This was already supported for Cycles shader nodes, but now also works for
Eevee and compositing nodes. Instead of a generic NodeCustomGroup, now
there is ShaderNodeCustomGroup and CompositorNodeCustomGroup that can be
subclassed and registered.

This allows to have drivers on node trees.
Probably now it will be better to simply add parameters for any
ID node, to avoid such amount of manual work.
Initial idea was to not have nodes if it's not needed to avoid
any possible overhead. Having more robust system is probably more
valuable. We can always optimize overhead in one way or another.
We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

No need to have iterator loop in the view layer evaluation,
this only makes it more difficult to have base flags covered
by the dependency graph.
Other good thing is that we don't need to worry about whether
base has been removed from the evaluated view layer or not.

Was once again caused by an ambiguity of the entry/exit operations.
Only did for objects since those are the only one who needs this.
The rest types of IDs needs to be checked and only added extra
operations if needed (adding operations and relations causes some
overhead for evaluation, so need to be careful).
The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.
We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
The initial idea of using char pointer was to save some
memory since the dependency graph was kind of the one
with the main database.
Nowadays dependency graph should be separatable from the
main database and being self-sustainable.
Other issue which was caused by this pointer is the
re-tagging of operations during relations update: it is
possible to have node which as tagged for update but had
the owner of the name removed (i.e. driver or bone was
removed).
