Now all the fine-tuning is happening using parallel range settings structure,
which avoid passing long lists of arguments, allows extend fine-tuning further,
avoid having lots of various functions which basically does the same thing.
This statistics is only collected when debug_value is different from 0.
Stored in depsgraph node itself, so we can always have access to average data
and other stats which requires persistent storage. This way we also don't waste
time trying to find stats from a separately stored hash map.
The goal is: have id->recalc flags set to components which got changed.
To make it possible for render engines to check on a more granular basis
what changed in the object. For example, is it a transform which changed
or is it just some ID property changed which has nothing to do with rendering.
The tricky part is: we don't want duplicated logic in tagging and flushing.
In order to avoid this duplication, we store ID recalc flag in the component
node type information. That type information could easily be accessed by both
tagging and flushing routines.
Remaining part of the changes are related on changing the way how tagging
works. The new idea here is to have utility function which maps update tag to
a component. This way we can easily set ID recalc flags right away. Without
any duplication of ID recalc flags set in multiple flag handler functions.
With all this being said, there should be no user measurable difference for
now, it's a gigantic basement for some upcoming work and fixes.
Not only this helps merges form master to the branch, but also:
- Allows us to production-check changes as soon as possible.
- Avoids some unnecessary editors update about ID changes.
- Adds small optimization on queue size by always keeping one of the pointers
outside of the queue.
Currently this is a no-visible-changes change, but the idea is to use this
dedicated flag to tell which exact components of ID changed, make it more
granular than just OBJECT and OBJECT_DATA. Allow setting this field based
on what components new dependency graph flushed on evaluation.
The possible issue with just listing arguments is that it might not be clear
what particular value is used for. For example, is it a scene itself, or is
it a parent scene?
Not as if it's not very clear now, but better be explicit for the future,
and me reading code in 10 years.
This way we can inform editors about all edits at once. Currently this is not
used, but in the next commits we will inform editors about what exactly has
changed.
We should keep base_flags after CoW object datablock was updated. Not entirely
happy with current solution, but it fixes crash and allows us to run tests
again.
More proper solution would be to make CoW operation a per-component thingie,
which will only update corresponding parts.
There were following issues:
- This was used in a similar way of DEG's ID update callback. No reason to have
yet-another-way of informing editors/engines about changes. Better to keep
regular update mechanism usable and fast for those needs.
- It wasn't granular at all, and granularity in flags is something what we
need to support anyway, even for existing ID update.
- There is no reason to have it per-object. Depsgraph operates on IDs.
- It wasn't clear when and who clears the flag, and was possible to run into
conflicts.
This is crucial bit since batch cache is stored in the evaluated object,
meaning we can't tag it's hatch cache dirty from the notifier system.
Not easily at least. Better to leave this job to depsgraph, it knows
all the copies of data.
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

Was never actually used and implementation seems to be slow: we shouldn't be
doing per-node evaluation hash lookups, adds too much overhead. We can instead
store statistics in the node itself, and maybe even group them somehow.
Ideally such a statistics should be user-friendly so riggers and animators
can see exactly what's happening.

This way evaluation routines will know which exact depsgraph evaluation
is happening for.
Mainly needed to get evaluation flags associated with ID nodes.
This solves issue with user counter on materials, objects and such,
additionally avoids having too much overhead of temporary lock and
datablock allocation.
Still need to do similar thing for scene copy, and look into nested
ID datablocks somehow.
Before it was a compile time option which was not very easy to use or test. Now
the project is getting more mature, so very soon we will be able to call for a
public tests of limited features.
The copy-on-write (which includes animation, modifiers) is enabled using
--enable-copy-on-write command line argument.
Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.
The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.
Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.
* use_scene_settings
* properties editor: workshop + organize context path
Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.
This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.
Properties Editor: Add Workspace and organize context path
==========================================================
We now have the properties of:
Scene, Scene > Layer, Scene > World, Workspace
[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data
