Previously, the ctrl+F search was only searching for either node names or explicitly
labeled nodes. Now it takes dynamic labels like node group nodes into account
making it much more useful.

Make release/bin/blender-launcher and release/bin/blender-softwaregl not
covered by the filters.
Also tweak the filter for .so libraries, making it so doc/doxygen/doxygen.source.h
is not considered to be covered.
For the official GitHub mirror and other repositories that do not include LFS
files, this adds an `lfs-fallback` remote. It will be used automatically if a
file can't be found on the regular remote.

This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.
The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.
More detailed explanation and conversation can be found in the
design task.

This adds basic unrolling support for 2 syntax:
- `[[gpu::unroll]]` which does full loop unrolling
- `[[gpu::unroll(x)]]` which unrolls `x` iteration
Nesting is supported.
This change is motivated by the added cost in compilation
and execution time that some loops have even if they have
compile time defined iteration counts.
The syntax is inspired by `GL_EXT_control_flow_attributes`.
However, we might want to have our own prefix to show it is
a blender specific feature and that it differs from the standard.
I propose `[[gpu::unroll]]`.
In the future, we could extend this to support more directives that
can be expanded to backend specific extension / syntax. This would
avoid readability issue an error prone copy paste of large amount
of preprocessor directives.
Currently, given that GL's GLSL flavor doesn't support
any of these attributes, the preprocessor does some copy-pasting
that does the unrolling at the source level. Note that the added
`#line` allow for correct error logging.
For the `[[gpu::unroll]]` syntax, the `for` declaration
needs to follow a specific syntax to deduce the number
of loop iteration.
This variant removes the continue condition between iteration,
so all iterations are evaluated. This could be modified
using a special keyword.
For the `[[gpu::unroll(n)]]` syntax, the usercode needs
to make sure that `n` is large enough to cover all iterations
as the loop is completely removed.
We could add shader `assert` to make sure that there is
never a remaining iteration.
This behavior is usually different from what you see in other
implementation as we do not keep a loop at all. Usually, compilers
still keep the loop if it is not unrolled fully. But given we don't
have IR, this is the best we can do.
`break` and `continue` statement are forbidden at the unrolled loop
scope level. Nested loop and switch can contain these keywords.
This is accounted for by checks in the pre-processor.
Only `for` loops are supported for now. There are no real
incentive to add support for `while` given how rare it is
in the shader codebase.

When baking multiple line art modifiers at once, line art can pick the
wrong cache data and free it before all modifiers have finished baking.
This fix corrected that logic so that when baking all line art, it will
always use/create/free the correct cache data.

This patch removes the Premultiplied option from the Alpha Over node.
The reasoning is as follows:
- The option mixed between alpha being straight and premultiplied, a
state which doesn't happen in practice.
- The option conflicts with the Convert Premultiplied option, if it is
not zero, then Convert Premultiplied does nothing.
- The option is implemented in a lossy way. It premultiplies the alpha
assuming it is straight, then converts the result to straight again,
then mixed between both results. This is as opposed to mixing the
original straight input with the premultiplied input. The successive
alpha conversion causes data loss in transparent regions.

This adds inital Grease Pencil support for node tools.
Node tools work in `Object Mode`, `Edit Mode`,`Sculpt Mode`,
and `Draw Mode`.
While Grease Pencil has many editing tools, including editing
multiple frames at the same time, for now, node tools only
allow editing the current frame.
Currently, the idea is that node tools can do arbitrary changes
to the drawings, but cannot do changes to the existing layer tree, e.g.
changing the order of layers, removing a layer or groups, etc.
All the node tool specific nodes like `Selection` and `Set Selection`
are adapted to work with Grease Pencil. In `Draw Mode`, we currently
interpret everything as selected.
The `Active Element` node has a `Layer` mode that provides the
index of the active layer (if there is one).
When `Auto-Key` is used, a new keyframe is created on the
current frame.
Locked/invisible layers cannot be edited with node tools.

Exposes bézier handle data through a new `GreasePencilStrokePointHandle`
class on each point, which provides `position`, `type`, and `select` for both

Also removes the old separate point attributes:
* `handle_left_type`, `handle_right_type`
* `select_handle_left`, `select_handle_right`

This avoid having to guards functions that are
only available in fragment shader stage.
Calling the function inside another stage is still
invalid and will yield a compile error on Metal.
The vulkan and opengl glsl patch need to be modified
per stage to allow the fragment specific function
to be defined.
This is not yet widely used, but a good example is
the change in `film_display_depth_amend`.

This patch removes the Convert Premultiplied option from the Brightness
and Contrast node. The reasoning is that it is the only node that has
the option to operate on straight alpha, while not being particularly
different. Adding alpha conversion nodes around it is also very easy.
Furthermore, alpha conversion is a lossy operation, so the option looses
data in emissive pixels, and since it is enabled by default, users not
familiar with the exact mechanism of the option wouldn't know how to fix
this.

No grammatical justification for this comma in English lexicon.
A similar and correct use would be this:
"Blender as a whole is licensed under the GNU General Public License, Version 3.
Individual files may have a different, but compatible, license."
But that's far more clunky, so it's best to simply remove the comma.

Relative imports are intentionally avoided in UI code (`scripts/startup/bl_ui`) because it makes it impossible to run individual files in isolation.
Common workflow for making mock-ups and quick UI edits is to load the UI file in Blender's text editor with "Edit Source" operator, make changes, and run the script to see the changes. But in the current version it's impossible because files include relative imports, which don't allow Python to run scripts individually.

Previously to handle unevaluated objects in line art "load all"
iteration, a `include_objects` variable is added in depsgraph
iteration settings, and this was only processed by object iterator
but not for any of the dupli objects. Now `make_duplis_collection`
will also handle `include_objects`
The only case where this border case can lead to crash is that a
line art grease pencil object is inside one of the dupli collection,
which isn't a valid use in the first place. But this fix makes it
more robust.

When copying a brush from a linked library to the current main, the fake
user flag is set, but the user count is set to 0. This later means that
saving such a file does not persist the brush datablock, and the
associated invariants are violated.

Adjust the height of the remove icon SVG to match the add icon, ensuring consistent sizing across UI elements.
This resolves alignment issues when pairing SVG icons with text or font-based elements. A height of 1100px was chosen to vertically center the icon cleanly in Blender's UI without introducing fractional pixel offsets.
No visual differences are expected in Blender.

This converts the public `uiLayoutSplit` function to an object oriented
API (`uiLayout::split`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code (or vice-versa),
making it almost seamless.
`uiLayout::split` now returns an `uiLayout` reference instead of a pointer.
New calls to this method should use references too.
