The issue was happening with a specific file where the ID management
code was not fully copying all modifiers because of the extra check
in the `BKE_object_support_modifier_type_check()`.
While it is arguable that copy-on-write should be a 1:1 copy there is
no real need to maintain the per-modifier pointer to its original.
Use its SessionUUID to perform lookup in the original datablock.
Downside of this approach is that it is a linear lookup instead of
direct pointer access, but the upside is that there is less pointers
to manage and that the file with unsupported modifiers does behave
correct without any asserts.

The modifiers are mapped between original and evaluated objects based on
their session IDs. The pointer to original modifier is no longer needed
for the backup: it remained from the initial implementation which was
rewritten at some point.
This is a preparation for removal of the pointer to original modifier.
This will allow to keep the access to deprecated DNA proxy data in that
specific file, instead of allowing deprecated accesses in the whole
override kernel code.
Part of T91671.
Part of the resynching code would access collections' objects base
cache, which can be invalid at that point (due to previous ID remapping
and/or deletion). Use a custom recursive iterator over collections'
objects instead, since those 'raw' data like collection's objects list,
and collection's children lists, should always be valid.
Found while investigating a studio production file.
This is a temp fix for a memory leak where the VSE isn't aware that a
float representation of the image could exist. The VSE somehow doens't
clears it (refcounter is still 1).
The work around is just to let the image engine clean up all the data it
created. Potential this would add more overhead when buffers are needed
more than once.
This refactors how output attributes are computed in the geometry
nodes modifier. Previously, all output attributes were computed one
after the other. Every attribute was stored on the geometry directly
after computing it. The issue was that other output attributes might
depend on the already overwritten attributes, leading to unexpected
behavior.
The solution is to compute all output attributes first before changing the
geometry. Under specific circumstances, this refactor can result in a speedup,
because output attributes on the same domain are evaluated together now.
Overwriting existing might have become a bit slower, because we write the
attribute into new buffer instead of using the existing one.

Mistake in the 974981a637: f the edit data is not present then the
origindex codepath is to be used. Added a brief note about it on the
top of the file.
More ideally would be to remove edit mesh from non-bmesh-wrappers
but this would require changes in the draw manager to make a proper
decision about drawing edit mode overlays.
Now all proxies will always be converted to library overrides. If
conversion fails, they are simply 'disabled'.
This should be the last 'user-visible' step of proxies removal.
Remaining upcoming commits will remove internal ID management, depsgraph
and evaluation code related to proxies.
Also bump the blendfile subversion.

So far linked proxies were just kept as-is, this is no longer an option.
Attempt to convert them into liboverrides as much as possible, though
some cases won't be supported:
- Appending proxies is broken since a long time, so conversion will fail
here as well.
- When linking data, some cases will fail to convert properly. in
particular, if the linked proxy object is not instanced in a scene
(e.g. when linking a collection containing a proxy as an
epty-instanced collection instead of a view-layer-instanced collection).
NOTE: converion when linking/appending is done unconditionnaly, option
to not convert on file load will be removed in next commit anyway.
Part of T91671.
This will help when dealing with liboverrides from other library files,
e.g for resync or proxies conversion.
This commit only affects proxy conversion.

We have this node for shader and geometry nodes. Compositor can also

The geometry nodes modifier currently always adds a dependency
relation from the evaluated geometry to the object transform. However,
that can be avoided unless there is a collection or object info node in
"Relative" mode.
In order to avoid requiring dependency graph relations updates often
when editing a node tree, this patch doesn't check if the node is muted
or if the data-block sockets are empty before adding the dependency.

Using opt-in instead of opt-out to make code easier to read.
Add combined flag enum.
Making restrict an inverse flag option because it is so rare to

This adds the possibility to use the `gpu_BaryCoord[NoPersp]`
builtin to support barycentric coordinates without geometry shader.
The `BuiltinBits::LAYER` builtin needs to be manually added
to the `GPUShaderCreateInfo` in order to use this feature.
Note: This is only available for shaders using `GPUShaderCreateInfo`.
A geometry shader fallback is generated if the extension
`AMD_shader_explicit_vertex_parameter` is not available.
`NV_fragment_shader_barycentric` was not considered because it is not
present inside the `glew.h` with use and seems to only be available
with vulkan.

If an entire cyclic stroke was selected, calling "Separate by Points"
would leave a gap in the new object (making the new stroke non-cyclic).
The patch makes sure that if we separate by points and all points are
selected, we fall back to separate by stroke.

This patch fixes the error that pops up
(`Error: Unable to execute '... Mode Toggle', error changing modes`)
when trying to switch to e.g. draw mode from a grease pencil object
that was saved in draw mode in an inactive scene when the file was loaded.
Note that this does not fix the bigger issue described in T91243.
The fix makes sure that we reset all the mode flags on the grease pencil
data when we set the mode to object mode.

When adding an asset library in the Preferences, set the name of the new
library to the chosen directory's name by default. That avoids having to
set it manually which can be annoying. Previously I thought it would be
nice to show the name button in red then, making the user aware that
they have to give it a name, but that appears to be more annoying than
useful/practical after all.
