This improves performance by reducing the amount of false positives.
A self overlap is made, so the distance from the vertices in the
overlap nodes is actually added.
Blender supports locking vertex groups to prevent changes to the
weights. However, as mentioned in comments for D3837, it is hard
to use this because there is no interface for locking in 3D View.
This adds a red shade to bones that are associated with a locked
weight group during weight paint mode, as the first step to adding
such interface. The next step is adding a pie menu for lock/unlock.

Once again, am not exactly sure why that was working before, and not
anymore - but in any case, doing that kind of update here is not only
useless (since we have to do it at the end of the whole
collections/objects duplication and remapping anyway), it is also rather
dangerous, as collections are currently in rather invalid states at that
point of the code...
Note that in ideal world, `BKE_main_collection_sync()` & co would be
lazy (setting only a flag, then code actually needing this to be valid
again should call some sort of `BKE_main_collection_sync_ensure()`).
Then we would not have to worry about such things (and we'd get nice
performance improvements in some cases, also in main remapping code,
etc.).
Food for some refactoring, some day...
Simplify a bit, and remove some now redundant remappings.
As a side note, rBac723db57fd8ba5 actually also fixed some unreported
issues (missing remappings to new objects/collections in new copied
scene, that were not previously handled by the 'custom' code).
There are almost certainly still some missing remappings around,
though...
rBac723db57fd8ba5 makes proper remapping of all pointers in Scene...
including the object pointers of bases in ViewLayers.
Using `BKE_main_collection_sync_remap()` makes sense here anyway
(compared to `BKE_main_collection_sync()`, it additionally clears caches
in ViewLayers and Collections), this whole code makes a lot of
remapping.
Note that I do not really understand *why* that was working OK
before rBac723db57fd8ba5. I.E. *why* not remapping at all ViewLayers'
base object pointers seemed to be OK...
This whole collection/viewlayer caching is very hard to follow, and
really needs a full rework at some point (just as much as ID copying
code in general, and scene copying code in particular, in fact).
Both actual Collection datablocks and the horrible master collection
should share the same code (there were already some differences,
although probably not critical, but some callbacks from
scene->master_collection did not have the 'not self' flag...).
### Description of the problem
Until now, it is only possible to correctly add a lightprobe in python via an operator:
`bpy.ops.object.lightprobe_add()`
### Description of the proposed solution
The idea of this patch is to fix the lack of consistency lightprobe creation without operator.
It allow creation of different lightprobe type directly via `bpy.data.lightprobes.new(name, type)` (such as for curves).
In order to make it possible I had to:
1. Add a function `BKE_lightprobe_configure` in charge of lightprobe settings configuration (avoid code redundancy)
2. Allow an object to take lightprobe datablock as data during is initialization.
### A short example of this patch usage
```
lp = bpy.data.lightprobes.new('some_name','PLANAR')
bpy.data.objects.new('toto', lp)
```

There were some visual artifacts when the spin gizmo had a rotation
greater than 360 degrees.
Avoids this by drawing the arc over the span of one rotation only
and adjusting the background color based on the rotation count.
This way we remove the need for the srgb boolean uniform and a lot of code complexity. However, mesh update is going to be a bit slower.
I did not benchmark the performance impact.
This also fix a typo in draw_cache_impl_particles.c and fix hair not using vertex color in workbench.

This will make this consistent with the behaviour of other start/end
ranges in blender. So start/end will instead be adjusted to always
satisfy the "start >= end" requirement instead of clamping the values.
EEVEE Soft shadows were not rendered correctly during viewport
rendering. The reason for this is that during viewport rendering the
shadow buffers were only update once and not per sample. This resulted
that all the samples calculated the same shadow.
This fix moves the call to `EEVEE_shadows_update` from cache finished to
draw scene. This needs to happen before `EEVEE_lightprobes_refresh`.

There is a cornercase when the user edits an uvmap, that is not part of
the material (yet). When this is the case the uvmap was not added to the
uv buffer and the 'pos' alias was not created.
This change will always request the active uv map when uv editing.

Seems like we need to set the error with the evaluated ModifierData.
Pass this to 'surfacedeformBind' and report with that.

This integrates hair collisions with the new cloth collision system,
greatly improving reliability, and reducing the amount of hair-specific
code paths in the cloth code.
The removes all the point constraint based collision stuff, instead
implementing segment impulse based collisions, using the same collision
response code as the normal cloth solver.
The hair system can now also collide with the emitter if it is a
collision object.

This avoids the problem where Blender doesn't start because
the PYTHONPATH points to an incompatible Python version,
see T72807.
Previously we chose to assume people who set the PYTHONPATH know what
they're doing, however users may have set this for non Blender projects.
So it's not obvious that this is the cause of Blender not to launch
on their system.
To use Python's environment vars, pass the argument:
--python-use-system-env
Note that this only impacts Python run-time environment variables
documented in `python --help`, Access from `os.environ` remains.
Old pre 2.5 files may have had non active spaces stored that doen't have
a header. The 2.5 versioning only added headers for active spaces, not
inactive (so invisible) ones.
Newer versioning code assumed there to always be a header though.
Inserted a version patch to make sure there's always a header now.
Fixes error reported to Debian,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035.
The last handle wasn't corrected, also, there is no reason
to flip the handles while sorting (checking the same handles many times)
move this into it's own loop.
`ARegion.alignment` unfortunately is a mixture of value and bitflag
enumerations. When checking for left/right/top/bottom region alignment,
the flags have to be masked out usually.
Most of the fixed cases here probably didn't cause issues in practice,
but could in fact break at any point when surrounding logic changes.
In fact the assert in #region_visible_rect_calc() failed in an older
file from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035. This
fixes it.
Outliner tree building code was not handling properly empty libraries
(i.e. Lib datablocks in our bmain which have no used actual data
anymore).
Main issue here is unclean states of indirect hierarchies of linking
involving several libraries after undo operation.
This is not a critical issue though, just annoying and untidy.
Just some rewording of the documentation of `Particle.uv_on_emitter()`,
so that it no longer refers to 'derived mesh' but 'evaluated mesh', and
document that it expects a modifier from an evaluated object.
No functional changes.
