The parenting was using the old logic, but with new engine the draw is done using eval data.
Fixed the depsgraph relationship missing with bones to get an update when the bone is transformed.
Also fixed Snap cursor to Selected

Was happening when having compositor open with Viewer node attached
directly to Render Layers output.
There were two things involved here:
1. The code which was storing CoW-ed versions of IDs was checking all
IDs for whether they are expanded or not. This was causing access
of freed memory for deleted IDs which do not need CoW (such as IM).
Simple fix: store ID type as a scalar and use early check before
doing more elaborate check based on accessing fields of id_cow.
2. The code which was ensuring view layer pointer is doing CoW for
scene. This isn't an issue on its own, but scene might have an
embedded ID such as compositor which was actually traversed by the
ID remap routines. This was causing remapping procedure to go into
non-updated copy of compositor, accessing freed Viewer image ID.
Solved by not recursing into embedded IDs for datablocks as those
are supposed to have own copy-on-write operations which takes care
of re-mapping.
Reported my Bastien, and also pair-coded with him.

We implement cubemap array support for EEVEE's lightcache reflection probes.
This removes stretched texels and bottom hemisphere seams artifacts caused
by the octahedral projection previously used.
This introduce versioning code for the lightcache which will discard any
lightcache version that is not compatible.

Unused no-op operation nodes are not bound to a callback function, and
have no outgoing relations. Incoming relations of such nodes are removed
since ff60dd8b18ed00902e5bdfd36882072db7af8735. However, this was done
too broadly, causing too many relations to be lost and indirectly linked
objects to be unevaluated.
This commit introduces a `DEPSOP_FLAG_FAKE_USER` flag for operation
nodes, which indicates they are not to be removed, even when they appear
to be unused.

This is the companion of D7031. That patch adds a new DIMENSIONS node to
the depsgraph for each object that has geometry. However, this node is
only necessary when there are drivers using an object's dimensions as
variable. Since this is rare, it's easiest to remove these nodes after
they turn out to be unnecessary. This is what (almost) happens in this
patch.
Removing nodes from the depsgraph is hard, and there are no functions to
do this yet. Instead, this patch recursively removes all the incoming
relations from unused no-op nodes (i.e. no-op operation nodes without
outgoing connections). Actually removing the nodes will be left as a
future improvement.
I've tested this on a Spring file [1]. Here are there results of blender
--debug-depsgraph-time spring_02_055_A.eevee.blend and letting it run
for a while to stabilise the reported FPS:
master: 11.7 FPS
Just D7031: 11.7 FPS
Just D7033: 11.8 FPS
Both D7031 + D7033: 12.3 FPS

This fixes an issue where drivers using `object.dimension` only add a dependency on `GEOMETRY` to the depsgraph, whereas they should also depend on `TRANSFORM`.
This patch adds a new no-op operation that depends on the geometry and transform components to the Parameters component.
An alternative implementation would be to have `RNANodeQuery::construct_node_identifier` return multiple node identifiers. However, this would spread throughout the depsgraph code and unnecessarily force many other functions to either return or handle multiple nodes where in 99.999% of the time a single node would suffice.
The new `DIMENSIONS` node is added for each object. An upcoming patch will go over all no-op operation nodes and remove them from the depsgraph. Since this is a more dangerous operation, it'll be reviewed separately.

This is in preparation of new object types. This only changes mesh_eval, we
may do the same for mesh_deform_eval and other areas in the future if there is
a need for it.

This fixes a threading issue (T73593) between drivers that write to the
same memory address. Driver nodes in the depsgraph now get relations to
each other in order to ensure serialisation.
These relations are only added between drivers that target the same
struct in RNA, which is determined by removing everything after the last
period. For example, a driver with data path
`pose.bones["Arm_L"].rotation_euler[2]` will be grouped with all other
drivers on that datablock with a data path that starts with
`pose.bones["Arm_L"]` to form a 'driver group'.
To find a suitable relation within such a driver group, say the relation
(from → to), a depth-first search is performed (turned out to be
marginally faster than a breadth-first in my test case) to see whether
this will create a cycle, and to see whether there already is such a
connection (direct or transitive). This is done by recursively
inspecting the incoming connections of the 'to' node and thereby walking
from it towards the 'from' node. This is an order of magnitde faster
than inspecting the outgoing connections of the 'from' node.
This approach generalises the special case for array properties, so the
code to support that special case has been removed from
`DepsgraphRelationBuilder::build_animdata_drivers()`.
A test on the Spring rig [1] shows that this process adds approximately
8% to the build time of the dependency graph. In my test case, it takes
28 ms for this process on a total 329 ms construction time. However,
since it also made some code obsolete, it only adds 24 ms (=8%) to the
construction time. I have experimented with a simple cache to keep track
of known-connected (from, to) node pairs, but this did not significantly
improve the timing.
Note that animation data and drivers are already connected by a
relation, which means that animating a field and also changing it with a
driver will not cause conflicts.

This partially fixes T73593.
The `add_relation(driver_key, property_entry_key, ...);` call can fail
in the following situation:
- A collection is linked, and instanced into the scene by an Empty.
- The collection contains an object with a driver on its `hide_render` or
`hide_viewport` property.
As the object doesn't exist as a real object in the scene, it's added with
`base_index=-1` to the depsgraph (see `DepsgraphNodeBuilder::build_collection()`).
As a result the node for syncing the restrictflags back to the base
isn't present in the depsgraph, and the `add_relation()` call failed.
This commit fixes the warning, simply by not attempting to add the
offending relation.

Image animation should not be an depsgraph node of type ANIMATION, there is
no need for it to be affected by the special casing for that.

Using a struct here allows to change given parameters to the callbacks
without having to edit all callbacks functions, which is always noisy
and time consuming.

This dependency was removed in fd0bc7e002ced8ffd85e9aa3edcae173dbd13392,
as there already were dependencies ANIMATION -> PARAMETERS and
PARAMETERS -> CACHE, making ANIMATION -> CACHE unnecessary.
Upon subsequent inspection, the ANIMATION -> PARAMETERS dependency was
there due to the fallback behaviour in
`RNANodeQuery::construct_node_identifier()`. Now this is no longer
relied upon, and the required relation is made explicit again.

The dependency graph has to know whether a driver must be re-evaluated
every frame due to a dependency on the current frame number. For python
drivers it was using a heuristic based on searching for certain sub-
strings in the expression, notably including '('.
When the expression is actually evaluated using Python, this can't be
easily improved; however if the Simple Expression evaluator is used,
this check can be done precisely by accessing the parsed data.

It was printing "frame" time instead of FPS.
Other interesting thing to get solved is to solve "drop" in FPS
when there is an idle time in user input.
Current usecase is limited to observing FPS when there is a continuous
stream of events: for example, keep moving vertex in edit mode while
watching debug prints.
|
|
The FPS here is measured based on a timestamp from when depsgraph
was previously evaluated.
Allows to ease investigating performance improvements/regressions
which are not related on animation system but on modifications on
a single frame (such as transforming vertex in edit mode).

When there are ID properties on an object, and these are animated and
used by a driver, the depsgraph has proper connections between ACTION →
ID PROPERTY → DRIVER.
When these properties are defined on a mesh, however, the depsgraph
relations are incorrectly created between GEOMETRY → PROPERTIES_EXIT →
DRIVER (because it's assumed that 'source = ENTRY' implies 'geometry').
This patch solves this by first checking whether the targeted property
is an ID property and handling it accordingly. This also made it
possible to remove some special cases from pose bone relations.

FreeStyle line styles were not part of the dependency graph, and
blacklisted from the Copy-on-Write system. As a result, animated
FreeStyle properties would not be updated by the animation system,
resulting in T72213. There was an explicit call to run the animation
system on the original datablocks, but that was (for good reasons)
removed in D5394.
This commit adds the FreeStyleLineStyle datablocks to the dependency
graph and allows them to be handled by the CoW system. As a result
- the UI now updates properly when properties are animated, and
- animated property values are actually used when rendering.
This commit includes @Sergey's patch P1222, which unifies two bits of
code that did the same thing: check whether datablock type is covered by
copy-on-write.
