The root of the issue comes to the fact that sub-data pointers were
used to match strips before/after copy-on-write. The undo system might
re-use sub-data pointers after re-allocating them, making it so that,
for example, pointer used by sound strip is later re-used by video
strip.
This fix takes an advantage of recently introduced per-sequence UUID
and uses it to match sequences before/after copy-on-write.
Will trigger code paths which makes sure UUIDs are generated and
are unique.
Enabled with --debug-depsgraph-uuid (which is also implied by
--debug-depsgraph).
This is the first step for having sequences covered with session UUID
with the goal to remove code which uses original sequence pointer to
match sequences.
Currently this UUID is maintained on file load, allocation and leaf
duplication function.There are more cases to cover and ensure UUID
is re-generated or re-used when needed. It will be done as follow-up
development.
Allows to use pre-defined structure for session UUIDs in all data
structures which needs it: pose channels, sequencer strips, modifiers.
The goal of all this is to have a reliable way of matching original
and copy-on-written versions of data, so that it's possible to
preserve runtime caches.

This was reported for the FCurve modifier restrict ranges, but might fail
elsewhere, too. Reason is that the post_but has its range (hardmin/
hardmax etc) set before the updates to the active button take place, so
changes here dont end up on the post_but (even though the RNA range
function is properly called for a new defined button - new one is not the
same as the post_but though).
Now update the ranges on the post_but when that gets active.

These were added in rB146473f08335e8cb774ccaf1baad82a1d308fbe1 however
there were a few errors with the labels:
1. Underscore in label
2. Abbreviation when not needed
Collection instance datablocks were not filtered out when only showing
the selected object. They were treated as a collection (which should
show when filtering objects). Adds a case to check if the parent is an
object.
This patch adds a new compound shape entry to the shape selection
dropdown. It also corrects wrong inertia calculation for convex hulls,
that resulted in strange behavior for small objects.
The compound shape take the collision shapes from its object children
and combines them. This makes it possible to create concave shapes from
primitive shapes. Using this instead of the mesh collision shape is
often many times faster.

Caused by {rBa1a333a1e92e}
`BKE_sequencer_prefetch_get_original_sequence` cant get a sequence in
`BKE_sequencer_cache_put`.
rBa1a333a1e92e moved multiple NULL checks (including the one checking
seq) above BKE_sequencer_prefetch_get_original_sequence (this should
never return NULL really, but this is for another fix).
So solution suggested by @ISS is to just stop prefetching all together
before changing content of seqbase.

- add the use of DRWShaderLibrary to EEVEE's glsl codebase to reduce code
complexity and duplication.
- split bsdf_common_lib.glsl into multiple sub library which are now shared
with other engines.
- the surface shader code is now more organised and have its own files.
- change default world to use a material nodetree and make lookdev shader
more clear.

Previously, deform brushes were modifying the final positions in the
simulation directly, which was causing all sorts of artifacts in the
deformed area and problems with other features of the solver.
Now these brushes deform a separate array of positions and the solver
adds constraints to them, so the real vertices are moved when solving
the constraints. This prevents those artifacts and gives the brush a
much better behavior.

The cloth brush builds the constraints when the stroke starts usign the
current state of the mesh. This means that deformations profuced by the
simulattion will accumulate after multiple strokes as it will always
start from the previous deformed state. While this is useful in many
cases, for other uses it is convenient to always simulate the same
initial shape, but applying different forces to it.
The persistent base options work like the persistent base in the layer
brush and allows the cloth brush to not accumulate deformation after
each stroke. When enabled, constraints are created for the shape stored
in the persistent base instead of from the current state of the mesh.

This is part of T79273 where separating a stroke would result in
multiuser gpencil data for the original object.
Real underlying issue seems to be that gpencil multiuser objects (also
the ones created by Alt+D duplicating) have a problem evaluating
modifiers correctly [this will need further investigation].
Not sure if this is a limitation of D5470?
This patch only corrects the usercount on separating [which already fixes
the scenario reported because singleuser gpencil modifiers work
correctly].
Note: we could have also called `ED_object_add_duplicate` with the
`USER_DUP_GPENCIL` dupflag -- that would have taken care of the usercount
--, but then the whole following logic in `gpencil_stroke_separate_exec`
would need to change from **adding** layers/frames/strokes to
**removing** these.
