Although c9fa73a379 made the problem worse. The incorrect to snap to
edges when one of their vertices is behind the viewer is much older.
The problem occurred because, in perspective mode, when we project a
vertex with negative "zfac", its projected value is undefined as it
depends on the position of the other vertex.
Thus, both the distance test and the lambda in these cases were wrong.
The solution was to calculate the snap point directly in 3D, using
`closest_ray_to_segment_v3` and avoiding projecting the edge.
This was caused by the base page tagging.
Since that the base page is now required for fixing
soft shadows, it would be the first level to be rendered
which, combined with the update throttle, lead to only
the min LOD to be available when the shadow was updated
in viewport.
This was affecting the jittered shadows, animation update
and viewport transform.
The fix is to only request the base page after throttling
the updates and only if there is no other LODs to be
rendered. This mean jittered shadow in viewport might
become affected by the missing base page artifacts, but
this is less noticeable than huge light leaking.

The following operations have been removed for system repositories:
- Installing from disk.
- Uninstall extensions.
- Delete files (when removing the repository).
Also change the operator to remove a repository so the option to
remove files is now a boolean instead of an enum. While a dynamic
enum can be made to work, this option is logically a boolean.
The `Snap to Grid` and `Snap to Vertex` modes were being mixed if
either mode was enabled.
Support for mixed snap modes doesn't yet fully work for UVs.
When starting a navigation operation that uses `Auto Depth` or
`Orbit Around Selection` the value of `#RegionView3D::dist` is modified
to match the distance from the new pivot.
This value was incorrect when the pivot was behind the viewer.
In these cases `dist` is negative.
This commit, in addition to fixing `dist`, also limits the execution of
this code to only when `Auto Depth` is used.

Allow precompiling specialization constants variations in parallel.
Only supported in OpenGL as the rest of the batch compilation API,
on the other backends the function is a no-op.
This also moves the `SpecializationConstant` from
`gpu_shader_create_info` (private API) into`GPU_common_types`
(public API).

This changes fixes a wrong mesh as a result of apply base mesh from the Multires modifier
In the previous code some corner vertices where incorrectly assigned to null and skipped form processing as a safety guard
that was only relevant when the mesh had hidden faces in edit mode. The hidden corner vertices bug is handled now when checking

Since the patch that caused this error was a fix to a previous infinite loop bug,
I also tested and made sure this updated patch still fixes the original issue it was trying to fix.
Note: This PR replaces #122845 due to a large amount of git rebase issues.

Previously selected strips in VSE timeline were drawing their outline
1px outside of the strip boundaries. This makes outlines of the strips
overlap each other when neighboring strips are selected.
Now the selected outline is fully within regular strip shape.

The File Output node ignores color space overrides for EXR images. To
fix this, we save the images using save_as_render set to true. We don't
need to provide this as an option similar to other image types because
even when save_as_render is set to true, it will not have an effect
unless the user chooses to override the color space explicitly, since it
is not affected by view transforms and the like.

The File Output node forces all inputs to have the same size, which
should only be the case for multilayer files. This is a regression in
931c188ce5. To fix this, we allow inputs to have any size, except for
multilayer files, which are realized on the automatic operation domain
of the operation.

The CPU compositor does not recognize viewer groups inside node groups
unless a viewer node exists at the top level node group. This is caused
by bad logic when registering viewer node at the node operation builder.
And the fix is just to correct the logic to always register viewers if
no active viewer already exists, which can then later be overwritten if
a viewer node that takes precedence was discovered.

Right now probe passes are compiled one by one, since passes are only
requested if `materials.queued_shaders_count` is 0 and requesting a
pass will increase the number.
This splits the logic into 2 functions, one for checking if sync is needed
and another to check if pass shaders are needed.
This allows compiling the shaders in parallel.

PR #122576 added rounded corners to VSE timeline strips, but they were not
"snapped" to pixel grid so the outline that is normally 1px was sometimes
falling in between pixels and was blurred out.
Fix by rounding all SDF related coordinates inside the shader to the pixel

Mainly correct/update some comments (e.g. missing reference to Boolean
type), and add some notes essentially about issues with current IDProp
String code (see also #86960 ).
No functional change.
In case a 'compatible' old IDProperty exists,
`update_input_properties_from_node_tree` would essentially reuse it
as-is, only keeping the UI data from the freshly new IDProp it created
for the socket.
This commit instead fully re-use the newly created idprop, only copying
(and converting as needed) the value from the old one.
That way, we can be sure that the actual type of the IDProperty is reset
to its expected type, instead of being kept forever in a 'wrong' type.
Having IDProps in a stable, expected type is a sounder behavior in
general, and critical for lower-levels of code to work as expected
(like RNA diffingi, and by extension, Library Overrides e.g.)
NOTE: This is a side-finding from work on #122743 to make some idprops
statically typed, and is a pre-requirement for this to work with the
GeoNodes modifiers case.

This fixes a bug that happens when two drawings in the same grease pencil
data-block reference the same array. In this case, the same attribute array
pointer is written to .blend files for both drawings. However, when loading the
.blend file, it was not detected that the data is shared. Instead each drawing
would think that it was the single owner of the array even though it was shared.
The same problem can technically occur for all kinds of shared data, and not
just for grease pencil. However, only grease pencil shows this issue currently,
because it can easily happen that the same attribute is shared between different
`CustomData` within the same data-block. This very rarely happens with meshes or
curves, because different `CustomData` usually have different sizes and don't
share the same arrays.
A previous fix (cc891aa699) solved pretty much the same issues for the case
when two layers in the same `CustomData` share data. This original fix is now
generalized and is integrated with `BLO_read_shared` which makes it less error
prone. For each data-block, the `BlendDataReader` now remembers which shared
data it has loaded before so that it is not loaded again.
In the future this could be extended to support data that is shared between
data-blocks, but that's not as straight forward as one would hope currently. For
various reasons, different data-blocks could store independent data at the same
pointer. I specifically noticed that with a regression test file:
`blender/tests/data/modeling/geometry_nodes/attributes/attribute_statistics.blend`.
To support it, one solution could be to tag `BHead` in .blend files to indicate
that a specific pointer is shared and unique within the entire file. But that's
for another day.

The buttons to upgrade or sync extensions called extension
operators via bpy.app.handlers, requiring awkward glue-code
which didn't show error reports in to the user.
Remove these operators and call the upgrade & sync operators directly.
Instead of using "box" layouts for these import/export operators, use
panels instead. Many choices for the layout and organization has come
from the `universal-scene-description` branch though it's not a 1:1
equivalent.
Motivation for using panels is two fold.
Firstly the use of panels instead of boxes is more consistent with other
parts of Blender and with the other IO features.
Secondly, in the case of an Import invoked from drag-n-drop or Export
configured on a Collection, the large number of options exposed results
in a very long layout. Panels allow us to close some sections by default
and allows the user to open/close panels based on their own needs in
general.
Along the way some effort went into standardizing the layout and wording
used as much as possible.

Support for "System" extensions as an alternative to the current
"User" extensions repository.
The purpose of this change is to support bundling extensions for
offline work or in environments where users setting up thier own
extensions isn't desirable, see #122512.
Details:
The default "System" repository on Linux will for example use:
- `/usr/share/blender/4.2/extensions/{system}` For system installs.
- `./4.2/extensions/{system}` For portable installs.
- Blender's default startup now has a "System" repository
which users or administrators may populate.
- Repositories can select between User/System paths,
setting a custom path overrides overrides this setting.
- Add "BLENDER_SYSTEM_EXTENSIONS" (matching "BLENDER_LOCAL_EXTENSIONS").

If the mesh has a curve builtin attribute that's not stored on the point domain,
the creation of the attribute will fail and it can't be interpolated. Possibly this
could be supported somehow, by averaging all the values in the curve's points
or so, but for now just avoid the crash.
Update PBVH GPU argument initialization to prefer using the PBVH mesh
attributes instead of the evaluated mesh attributes for color.
The values can be out of sync due to differences with the evaluated
and original mesh data.

The goal is to simplify debugging the "current" simulation step. Previously, when a frame
was cached already, one would have to go back to the beginning to cache everything again.
Now, the last cached simulation step is discarded and simulated again if any property that
affects it is changed.

Originally this would replace scripts that come bundled with Blender,
but it's unclear how this is useful.
Searching for this online mainly leads to people asking how they can
use it to add scripts. For example in a studio environment you might
want to deploy add-ons and startup scripts for all users.
Even if you wanted to use it for replacement though, it wasn't really
doing that and inconsistent for different types of scripts:
* startup: ignored
* modules: replaces bundled scripts
* presets: adds to bundled scripts
* addons (in 4.1): ignored
* addons_core (in 4.2): ignored
* startup/bl_app_templates_system: replaces bundled scripts
This change makes it add scripts from this path for all. This is a
breaking change, though arguably this feature was just broken to
begin with and not used much in practice because of that.
The alternative would be add a new set of environment variables to
avoid breaking existing behavior. But that also means keeping around the
broken behavior or fixing it in another way.
Supporting multiple paths may be used too, but for now just support
a single one as doing this for all BLENDER_SYSTEM variables is
non-trivial. The main use case for that would be add-ons anyway, and
those will mainly be handled through upcoming
BLENDER_SYSTEM_EXTENSIONS instead.

A bit on shaky ground here, but it looks like we actually dont want to
execute the hovered buttons value/op if we chose another item in the pie
menu. This can be achieved by using the **onfree** arg to
`button_activate_exit` called on the active(hovered) button.
Not sure if this is the correct solution tbh (but maybe it demonstrates
where the bug of #122526 can be located).
I have tested pie menus with this patch and they seems to behave
normally (even nested ones).
