While this probably isn't the final solution we'll go with, it's nicer
as current one, which was basically broken. So consider this as
temporary solution.
It also allows testing how changing workspace changes mode & active
object, but only by having the workspaces use different view-layers.
Decided to remove WorkSpace.mode for now. If we need to bring it back,
we'll have to version patch it anyway.
This option prevent from automatically blurring the albedo color applied to the SSS.
While this is great for preserving details it can bleed more light onto the nearby objects since the blurring will be done on pure "white" irradiance.
This issue is to be tackled in a separate commit.
When setting background object, it might pull new objects in and those objects
will not have proper flags unless on_visible_update() was called afterwards.
This reverts commit 90ff88646d.
Can not do this yet, if object is not part of graph yet it will not have entry
taq. Need some more generic solution here.
It is possible to have situation when we need to both update relations and do
some updates on random IDs. This was only done before for objects using their
recalc field. This means, every update tag which did not fit into there would
have been lost after updating relations.
Now we do some smarter re-scheduling of operations after relations are updated.
object.is_from_set
object.is_from_duplicator
We need them for the unittests, and users can benefit from it as well.
Note, this only makes sense when reading objects from depsgraph:
`bpy.context.depsgraph.objects`
Previously it was done during depsgraph iteration, which is not good at all,
since after evaluation nobody should really modify how object was evaluated.
The idea then is to avoid doing depsgraph tag for each of the object which
selection is changed (which could be tricky to do anyway due to lots of areas
of selection code where this could happen), and simply tag scene's with
selection update tag.
This will involve synchronization of flags from base to objects, which is
rather cheap anyway.
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.
This cleanup removes the need of gigantic code duplication for each closure.
This also make some preformance improvement since it removes some branches and duplicated loops.
It also fix some mismatch (between cycles and eevee) with the principled shader.
This is a hack to make the user control the SSS radius even though the profile is baked with the default radius values.
This is completly against UI principles since you cannot edit the profile radiuses while there is something plugged into the radius socket.
Better solution will be to either have a dedicated node value for RGB radiuses and a SSS scale socket only for eevee.
`BM_mesh_normals_update` was converted from OMP to new parallel iterator code,
basic test with heavily subdivided cube (24.5k faces) gives:
- old OMP code: average 10ms per run.
- new BLI_task code: average 6ms per run.
So new code seems to be easily 40% quicker, in addition to getting rid of OMP. ;)

It merely uses the new thread-safe iterators system of mempool, quite
straight forward.
Note that to avoid possible confusion with two void pointers as
parameters of the callback, a dummy opaque struct pointer is used
instead for the second parameter (pointer generated by iteration over
mempool), callback functions must explicitely convert it to expected
real type.
Also added a basic gtest for this new feature.
This will allow threaded tasks to 'consume' all mempool items in
parallel tasks, each one working on a whole chunk at once (to reduce
concurrency managing overhead).
