The new poly offsets were needed to interpolate attribute to a different
domain, but they were cleared when the legacy MPoly array was built.
Instead just clear the offsets a bit later after the other conversions.
Blender 3.5 has a performance regression in the image engine
that made the image engine 3-4x slower then 3.4. The cause of
this was the new way how panning was implemented.
This PR disables the new panning for now as a short term fix.
In the future the panning and improvements we did ensured
better performance when dealing with higher resolution images.
But the regression for regular images weren't acceptable.
This fix might introduce other performance regressions on
lower end systems.
In the future we still want to improve the performance to
get back to Blender 3.0 performance, but that requires more
work and has a different priority.

This is mistake in the refactor of the DNA storage which unified
the camera and object storage. The bit which was missed from the
initial logic is that the autosave does not use regular file
write.
Detect this in the do-versioning code and rely on the new data
format when it exists.
A candidate for 3.5.1 release.

Makes it possible to select multiple custom script directories in Preferences >
File Paths, replacing the single Scripts path option. Each of these directories
supports the regular script directory layout with a startup file (or files?),
add-ons, modules and presets.
When installing an add-on, the script directory can be chosen.
NOTE: Deprecates the `bpy.types.PreferencesFilePaths.script_directory`
property, and replaces `bpy.utils.script_path_pref` with
`bpy.utils.script_paths_pref`.

When using ASAN on Clang / Linux, the call to `find_library(... asan ...)`
works against us, as it finds GCC's `libasan.so`. To work with Clang,
we should simply not pass any explicit library, as Clang will figure things
out by itself with the `-fsanitize=xxx` options.
Furthermore, Clang is incompatible with `-fsanitize=object-size`, so that's
now also no longer passed on Linux (mimicking the Apple) configuration.
For the long run, it would be better to rewrite this entire section to
select behaviour on a per-compiler basis, rather than per platform. That's
tracked in #105956

Legacy drivers don't support auto type casting in comparisons.
This PR fixes some comparisons cast.

The shader was compiled without the right define, disabling the world
volume lighting.
This had nothing to do with the light path node as the lighting
was totally disabled.

This came up in #106591 which reported that changing a Light Group would
not work when alt-clicking the property field (which is the usual method
to edit a property for multiple objects at once).
This is because string properties were not supported in
`ui_selectcontext_apply` which is now done.
Similar to 1318660b04 [which added support for pointer properties].
Adding general support for string properties means this method can now
be used for many more things:
- changing all sorts of ID names (objects, meshes, ...)
- many settings in modifiers (e.g. vertexgroups)
- geometry nodes modifier properties (e.g. attribute names)
- ...
Fixes#106591

Updating the buffer scale increased the window size based on the
previous window scale. Since the previous scale (DPI) newly created
windows restored from a `.blend` file isn't known, don't scale the
window size when updating the window's scale for the first time.
When a window overlaps multiple outputs, always use the resolution
on the output with the highest resolution. This means Blender never
shows low resolution content up-scaled.
Share logic between fractional & non-fractional window scaling.
This also enables fractional-scaling without scaling fixed sized buffers
for compositors without support for fractional_scale_manager_v1.
There is a `KeyError` exception when the `install_linux_packages.py` build script is ran with `--distro-id`:
```console
$ ./build_files/build_environment/install_linux_packages.py --distro-id arch
INFO: Distribution identifier forced by user to arch.
Traceback (most recent call last):
File "file:///blender/./build_files/build_environment/install_linux_packages.py", line 1656, in <module>

distro_package_installer = PackageInstaller(settings) if settings.show_deps else get_distro_package_installer(settings)

return DISTRO_IDS_INSTALLERS[get_distro(settings)](settings)
KeyError: None
```
This happens because the `get_distro` function returns `None` if the distribution ID is forced with the `--distro-id` option, when it should return the provided value.

This patch implements the Map UV node for the realtime compositor. This
is different from the CPU implementation in that it relies on the
approximate EWA filtering provided by the driver's implementation of
anisotropic filtering to displace the texture. This is easier and faster
than implementing EWA manually in the shader and has identical quality
where it matters.

This patch implements the Fog Glow option in the Glare node. The
implementation does not match the existing implementation in the CPU
compositor, because it is computationally infeasible for the realtime
compositor. Instead, this implementation is similar to how Bloom is
implemented in EEVEE, based on the talk:
"Next Generation Post Processing in Call of Duty: Advanced Warfare".
This is just a temporary solution as requested by users until we either
implement an accurate implementation using FFT, provide a separate
option for EEVEE bloom, or roll out a different solution altogether.

This patch implements the Z Combine node for the realtime compositor.
The patch also extends the SMAA implementation to work with float
textures as a prerequisite to the Z Combine implementation. Moreover, a
mechanism for computing multi-output operations was implemented, in
which unneeded outputs will allocate a dummy 1x1 texture for a correct
shader invocation, then those dummy textures will be cleaned up by
calling a routine right after evaluation.
This is different from the CPU implementation in that the while combine
mask is anti-aliased, including the alpha mask, which is not considered
in the CPU case.
The node can be implemented as a GPU shader operation when the
anti-aliasing option is disabled, which is something we should do when
the evaluator allows nodes be executed as both standard and GPU shader
operations.

#### Summary
Occlude edit mode selection behind objects in object mode.
#### Problem
When doing retopology, you want to be able to select your edit mesh,
but only when you can see it.
Being able to select geometry behind reference objects is not
desirable.
#### Solution
Make it so reference objects occlude selection, while the edit mesh is
pushed towards the view using retopology offset.
#### Limitations
Poly Build is not supported, because it doesn't use the depth buffer.
It behaves the same as normal, unoccluded by reference meshes.
#### Notes
Selection occlusion is not used when xray is enabled. This is
intentional.

There is no point in checking if the allocation of this relatively
small array was successful. We only do that in very few places,
but here it just adds unnecessary complexity.
Similar to 8d0920ec6d and aef0e72e5a.
In a test case with 2 million curves and 15 million points
I observed a 10x performance improvement, from 2.2s to 0.2s
to copy the data from Blender to Cycles.
Similar to 8d0920ec6d.
In a test case with 8 million points and 3 attributes, I observed
around a 9x performance improvement, from 1.8s to 0.2s to copy
the data from Blender to Cycles. For some attribute types, using
implicit sharing could remove the need to copy entirely, but removing
the overhead from the RNA API makes sense anyway.
Only use the denoised buffer for access of denoised passes, and
access the rest of the passes from the original render buffer.
This allows in-place modification of the guiding passes needed
by the denoiser without affecting the final render result pixels.

Stored `ComponentIDKey` and `OperationIDKey` would still use string
references (char pointers) to data in related IDs, instead of using the
already locally stored std::string name of their matching `ComponentNode`
or `OperationNode` for that.
During undo, to reduce updates and speedup undo steps, a lot of IDs get
'replaced in place', i.e. new data read from the undo memfile is moved
into the existing 'old' ID memory address. And the depsgraph is also
re-used from the old BMain.
Calling `DEG_id_tag_update` and similar on the ID could then cause
depsgraph code to access freed memory from the 'old' data.
Joint effort with @sergey and the rest of the depsgraph team, thanks!
Issue caused by inconsistency in GPUFramebuffer viewport state
between Metal and OpenGL. The MTLFramebuffer code has been
modified such that framebuffer viewport/scissor state is retained
and only updated if attachments are modified during bind.
This is consistent with OpenGL. Previously, other updates to the
framebuffer in Metal would reset the viewport region, especially
if attachments were temporarily removed. This caused the color
picker selection to be misaligned.

Introduce a context manager that temporarily overrides a UILayout's
operator context.
Instead of writing this:
```py
default_op_context = layout.context
layout.context = 'OTHER_VALUE'
layout.do_stuff()
layout.context = default_op_context
```
you can now write this:
```py
from bl_ui_utils.layout import operator_context
with operator_context(layout, 'OTHER_VALUE'):
layout.do_stuff()
```
This is also exception-safe; it will always ensure the layout's operator
context is restored when the `with` body is exited, regardless of
whether that's done with an exception or regularly.
Idea in-the-hallway approved by @Sergey.
