There are still a few places that are more complicated where the replacement
to `IDP_New` isn't obvious, but this commit replaces most uses of the ugly
`IDPropertyTemplate` usage.
It is unknown why/how this can happen, but there are some files out there
that have e.g. Objects flagged as embedded data... See e.g. the
`(Anim) Hero p23 for 2.blend` file from our cloud gallery
(https://cloud.blender.org/p/gallery/5b642e25bf419c1042056fc6).
Not much to be done, but add another checking pass at the end of
readfile process to fix these.
This adds a new exprimental option to automatically convert GP legacy
data to GPv3 one.
It supports also linking and appending cases. Conversion also happens
when opening a file linking GP legacy data saved by an older .blendfile.

Compositor: Make Hue Correct node wrap
This patch makes the Hue Correct node as well as the Hue Correct VSE
modifiers to wrap, such that no discontinuities occur for the red hue.
Since it now wraps, the default curve preset now exempts the last point
of the curve.
A new CUMA_USE_WRAPPING flag was added to specify wrapping for curve
maps. The implementation works by adding two virtual points before and
after the terminal points in the curve map, such that their handles
match, and would then produce a continues curve.
This is a breaking change, since existing curves were also adjusted
using versioning. However, the change will not be significant, since in
most realistic cases, the terminal points will be close to each other,
and even with wrapping, the connection will be very sharp, almost
matching the old behavior.

Allow the user to scale shadow-map resolution per-light.
Adapt the PCF scale based on shadow-map to pixel footprint ratio,
since we can no longer assume that higher LODs don't need filtering.
This allows using much lower shadow resolutions, which can yield
quite significant performance improvements, with relatively little
perceptual quality loss (at the cost of softening shadow edges).
The per-light resolution scale is a literal scale, so for example 0.5
means half the resolution. The Scene Simplify Shadows setting has
been updated to match this behavior.

Those shouldn't really exist at all currently, since we forbid them in 354915cf3c.
Unfortunately, not all cases were removed, and many node trees with such sockets
have been created during the development of 4.1 due to the auto-smooth changes.
I'm not entirely sure if it's still possible to properly remove them now. The commit
above mentions that we might lose links due to changed identifiers. Maybe we're
better off just supporting these inlined sockets while also allowing the "align with
previous socket" functionality.
Either way, not creating more of such node trees for now is reasonable, since we
explicitly disabled that functionality for now.

This uses Spherical Harmonics to store the indirect lighting and
distant lighting visibility.
We can then reuse this information for each closure which divide
the cost of it by 2 or 3 in many cases, doing the scanning once.
The storage cost is higher than previous method, so we split the
resolution scaling to be independant of raytracing.
The spatial filtering has been split to its own pass for performance
reason. Upsampling now only uses 4 bilinearly interpolated samples
(instead of 9) using bilateral weights to avoid bleeding.
This also add a missing dot product (which soften the lighting
around corners) and fixes the blocky artifacts seen at lower
resolution.

Fix a crash when inserting a key with tweak mode enabled, but where
`AnimData::actstrip` was NULL.
The root cause of this is that two pointers in the `AnimData` struct
(`act_track` and `actstrip`) are expected to be set when NLA tweak mode
is enabled, BUT these are not exposed to RNA and thus invisible to the
library overrides system. As such, they are NULL when loading from disk,
while the `ADT_NLA_EDIT_ON` flag still indicates they are to be used.
Rather than adding a NULL pointer check (and having to add that in many
more places), I used this two-pronged approach:
- Extend the 'NLA tweakmode' override apply code, to set the `act_track`
and `actstrip` pointers when they are incorrectly NULL. This is done
by lookup of the track and strip by name.
- Add versioning code to exit out of tweak mode whenever the
`ADT_NLA_EDIT_ON` flag is set, but those two pointers are still NULL.
The last step was necessary with the example file attached to the bug
report, as that was saved with a buggy blender version. New saves work
just fine.

This PR fixes several issues with the versioning that replaces the old
auto smooth flag with a modifier.
One issue is that the flag wasn't cleared in the initial versioning
code. That means some objects have the replacement modifier but their
meshes still have the flag set. The fix for that is to make the
versioning idempotent by trying to find an existing node group before
adding a new one. The versioning is now re-run on all objects to clear
the flags. Flags on all meshes are cleared too, even unused meshes.
That could cause loss of the auto-smooth when the mesh is linked from
a different blend-file, but that situation should be very rare.
Another issue was that the versioning wasn't run when linking objects.
That was simple to solve by adding the versioning where the proxy
versioning already existed for that case.
Finally, arguably the largest issue was that the the newly added node
groups were always added as local data-blocks. When linking, having
library data-blocks point to local data-blocks not in that library is
quite bad and breaks assumptions around Blender. This is solved by
having an auto smooth node group per library.

This adds a "Solver" option to the geo boolean node, with the options
Exact and Float.
The current geo boolean node only uses the Exact solver.
This adds the ability to use the faster original floating point boolean solver.
The float solver has issues with coplanar and other coincident geometry,
but is generally much faster than the Exact solver, and users have asked
for this option (which is available in the Boolean Modifier and edit mode
boolean tool).
Like the modifier, the Float solver needs to convert the Mesh to BMesh,
do the operation, and then convert back to Mesh. It also has to do it
iteratively if more than two operands are supplied.
This is the first of a planned series of commits that will add a
new exact boolean solver, based on the Ember paper, as a solver option.
Ember will be much faster than the current exact solver, but may still not
be as fast as float, and also will not handle some non-volume-enclosing
inputs as well as Float, so it is likely that the Float solver will always remain.
We may eventually retire the old Exact Solver, however.
This commit also prepares for more sensible code in the future by
changing the internal enum names for the solvers to better reflect the
algorithms used: Fast -> Float, and Exact -> Mesh_Arr (which means
"Mesh Arrangments, the name of the paper upon which the current
exact solver is based).

Use snapping increments matching values used before this was
customizable. [0] changed snapping increments from 5 degrees to 15,
from 1 to 5 degrees with precision enabled.
[0]: 060174cf14
The core of the issue was that `sculpt_flag` was used by three different enums (`eGP_Sculpt_Flag`, `eGP_Sculpt_Mode_Flag`, and `eBrushFlags`). This resulted in the flag getting overriden because `ENUM_OPERATORS` expected the maximum value of `eGP_Sculpt_Flag` to be `(1 << 3)` which it wasn't.
The `sculpt_flag` was exposed through python as `"direction"`.
In the UI this meant that it was effectively used as `brush.direction`. This fix replaces `brush.gpencil_settings.direction` with `brush.direction`.
It also makes sure `sculpt_flag` is only ever used with values from `eGP_Sculpt_Flag`.

This PR initializes all brushes with the default automasking cavity
curve when a `startup.blend` file is loaded. Because there exists a
series of brushes that are added if they are not found in the
`startup.blend` file (e.g. "Paint") **after** the file is already
loaded, the existing fallback code to handle `nullptr` in the loader
code does not run.

One of the consequences of the mistake in 3fcf535d2e (fixed in previous
commit), was that the more recent `LIB_EMBEDDED_DATA_LIB_OVERRIDE` ID
flag could be wrongly set in some nodetrees from pre-2.76 blendfiles.
This commit adds a check that embedded IDs flagged with
`LIB_EMBEDDED_DATA_LIB_OVERRIDE` are actually embedded IDs of a
liboverride.
Pull Request: https://projects.blender.org/blender/blender/pulls/118921
In 3fcf535d2e, the `ID.flag` data was split, keeping persisten flags in
`ID.flag`, and moving runtime ones into a new `ID.tag` data.
Some versionning code was then added to cleanup the existing `ID.flag`
on file read, but embedded IDs (root node trees only, back then) are not
stored in Main data-base, and were skipped.
Note that this fixes the conversion of older (2.76.4 and older) files.
There is no reliable way to cleanup files opened and saved from more
recent versions of Blender unfortunately.
This adds implicit sharing support for the `MemFile` undo-step. This decreases memory
usage and increases performance.
Implicit sharing allows the undo system to take (shared) ownership of some data.
Previously, the data would always be serialized and compared to the previous undo-step.
So this turns an O(n) operation into O(1) (in terms of memory usage and time).
Read/write code that wants to make use of this has to use the new `BLO_read_shared`
and `BLO_write_shared` functions respectively. Those either make use of implicit-sharing
internally or do the "full" read/write based on a passed-in function. It seems possible to
use the same API in the future to store shared data to .blend files.
Improvements:
* Much faster undo step creation in many cases by avoiding the majority data copies
and equality checks. This fixes#98574. I found undo step creation and undo step
decoding to be 2-5 times faster in some demo files from the blender website and in
some production files from the Heist project.
* Reduced memory usage when there is large data in `bmain`. For example, when
loading the same highly subdivided mesh that I used in #106228 the memory usage
is 1.03 GB now (compared to 1.62 GB in `main` currently). The main remaining copy
of the data now is done by rendering code.
* Some significant performance improvements were also measured for the new grease
pencil type (#105540).
There is one main downside of using implicit-sharing as implemented here: `MemFile`
undo steps can't be written as .blend files anymore. This has a few consequences:
* Auto-save becomes slower (up to 3x), because it can't just save the previous undo step
anymore and does a normal save instead. This has been discussed in more detail here:
https://devtalk.blender.org/t/remove-support-for-saving-memfile-undo-steps-as-blend-files-proposal/33544
It would be nice to work towards asynchronous auto-save to alleviate this problem.
Some previous work has been done to reduce the impact of this change in 41b10424c7
and f0f304e240. This has been committed separately in efb511a76d.
* Writing `quit.blend` has to do a normal file save now. So it's a bit slower too, but it's
less of a problem in practice.
* The `USE_WRITE_CRASH_BLEND` functionality does not work anymore. It doesn't seem
to be used by anyone (removed in e90f5d03c4)
There are also benefits to not writing `MemFile` from undo steps to disk. It allows us to
more safely do undo-specific optimizations without risking corrupted .blend files. This
is especially useful when we want to preserve forward compatibility in some cases.
This requires converting data before writing the .blend files, but this conversion is not
necessary for undo steps. Trying to implement this kind of optimization in the past has
often lead to bugs (e.g. 43b37fbc93).
Another new problem is that it is harder to know the size of each undo step. Currently, a
heuristic is used to approximate the memory usage, but better solutions could be found
if necessary.
Pull Request: https://projects.blender.org/blender/blender/pulls/106903
In many modes, Blender uses the `MemFile` undo step, which serializes all DNA
data in RAM almost as if writing a .blend file. For auto-save, Blender used to
write the last `MemFile` undo step to disk because that was faster serializing
all of DNA again. Furthermore, saving the `quit.blend` file when closing Blender
also used this.
This functionality is now removed in preparate for supporting implicit sharing
in the undo system (#106903). Auto-save and saving the quit.blend file now use
regular file saving.
The removal of this feature and its implications have also been discussed here:
https://devtalk.blender.org/t/remove-support-for-saving-memfile-undo-steps-as-blend-files-proposal/33544
Add percentage closer filtering to shadowmap sampling and a
`shadow_filter_radius` property to lights to control it.
Notes:
* This adds PCF to `eevee_shadow_tracing_lib`, but not to
`eevee_shadow_lib`, which is used by volumes (not required) and
thickness.
* PCF is computed based on the LOD0 size. This assumes that higher
LODs are only used when the shadowmap resolution is actually good
enough to match the render resolution.

When an asset is heavily modified, all production files having
liboverrides of it will still try to link all their known linked
reference IDs, leading to potentially thousands of not-really-useful
warnings about missing IDs in the console.
Now that liboverrides resync cleans up better these left-over data, it's
better to report missing linked data _after_ the liboverride resync
process.
Note that the original place can still report all effectively missing
linked data if needed, but this is now a logging info, so it won't be
displayed anywhere unless explicitely requested.

This is a migration of the current Line Art modifier to GPv3.
Note:
- The modifier is using the exact same DNA structure as the old one, it's re-defined in a different name. At the moment all the variable names and placement after the `ModifierData` part should stay exactly the same until we do proper versioning of the modifier data and completely remove the GPv2 support.
- Vertex weight transfer feature no longer supports name initial matching ("group" used to match "group1","group2" etc). Now it will only transfer vertex weight from source vertex groups that has the exact same name as specified.
