Patch from Richard Erhardt, with some additions & modifications.
Changes bevel profile shape parameter so that can get arbitrarily
near square profile as parameter -> 1.
Adds code to make profile=0 case work, at least for cube corners,
so changed hard min of profile parameter to 0 from 0.15.
Currently shouldn't make any difference, but this is something what needs to be
done to sanitize drivers relations )with the idea to re-use some generic code
to get operations for driver variables.
Those are unused, and not clear whether we will ever support this.
Seems to be better having more like "component" tags, would be less magic
involved to guess what exactly is to be tagged.
One or two are OK, but more make it rather unreadable, and future work
is likely to require more toggle specific behavior here. So switched to
bitflags, switching from short to int and using 16 upper bits for
'internal' ones defined in BLO_readfile.h, combined with 'public' ones
from user interaction, defined in DNA_space_types.h
Updated collection_delete_exec() so we don't try to delete elements as we search
the outliner tree anymore.
Now we search the whole tree first for the selected nodes that need to be
deleted and delete them afterward.

Use dynamically generated message publish/subscribe
so buttons and manipulators update properly.
This resolves common glitches where manipulators weren't updating
as well as the UI when add-ons exposed properties which
hard coded listeners weren't checking for.
Python can also publish/scribe changes via `bpy.msgbus`.

This augment the existing irradiance grid with a new visibility precomputation.
We store a small shadowmap for each grid sample so that light does not leak through walls and such.
The visibility parameter are similar to the one used by the Variance Shadow Map for point lights.
Technical details:
We store the visibility in the same texture (array) as the irradiance itself (in order to reduce the number of sampler).
But the irradiance and the visibility are not the same data so we must encode them in order to use the same texture format.
We use RGBA8 normalized texture and encode irradiance as RGBE (shared exponent).
Using RGBE encoding instead of R11_G11_B10 may lead to some lighting changes, but quality seems to be nearly the same in my test cases.
Using full RGBA16/32F maybe a future option but that will require much more memory and reduce the perf significantly.
Visibility moments (VSM) are encoded as 16bits fixed point precision using a special range. This seems to retain enough precision for the needs.
Also interpolation does not seems to be big problem (even though it's incorrect).
Before this patch, if one of the grid was updated (moved) only the subsequents evaluated grids had their level reset and had all their bounces recomputed.
We do not assume subversion bump until we actually change the subversion.
For example, a branch may have bumped its subversion to 3, yet still require
the new doversion code introduced on 108c4bd502.
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 are using NC_SCENE | ND_LAYER_CONTENT for the shader, however this does not work for groups
unless we manually handle the notifiers.
Otherwise the group id is passed, and the listener never gets the notification since a scene id
is expected, or no id at all.
Allow users to edit either the object group active collection or view layer one
We can't support users selecting the group collections from the outliner group
because that would be imply having an active group for the scene or workspace.
But the way it is now allows to see and edit the collection values after the
group is instanced.
You could still create groups as before, with Ctl + G. This will create a group
with a single visible collection.
However you can also create a group from an existing collection. Just go to
the menu you get in the outliner when clicking in a collection and pick
"Create Group".
Remember to instance the group afterwards, or link it into a new scene or file.
The group and the collection are not kept in sync afterwards. You need to manually
edit the group for further changes.
