This patch adds a new `BKE_main_ensure_invariants` function. For now it only
ensures node-tree related invariants, but more may be added over time.
The already existing `ED_node_tree_propagate_change` now internally calls
`BKE_main_ensure_invariants`. We can probably remove this indirection at some
point and call the new function directly, but for now it is kept to keep this
patch small.
This is based on a recent discussion in the Core module meeting:
https://devtalk.blender.org/t/2024-12-12-core-meeting/38074
```cpp
/**
* Makes sure that invariants in original DNA data are maintained after changes.
*
* This function has to be idempotent, i.e. after calling it once, additional calls should not
* modify DNA data further. If it would, it would imply that this function does more than
* maintaining invariants.
*
* This has to be called after any kind of change to original DNA data that may be involved in some
* of the maintained invariants. It's possible to do multiple changes in a row and then fixing all
* invariants with a single call in the end. Obviously, the invariants are not maintained in the
* meantime then and functions relying on them might not work.
*
* If nothing is changed, this function does nothing and it should not be slower than checking a
* flag on every data-block in the given bmain.
*
* Sometimes, it is known that only a single or very few data-blocks have been changed (e.g. when a
* node has been inserted in a node tree). Passing in #modified_ids can speed up the function
* because it may avoid the need to iterate over all data-blocks to find modified data-blocks.
*
* Examples of maintained invariants:
* - Group nodes need to have the correct sockets based on the referenced node group.
* - The geometry nodes modifier needs to have the correct inputs based on the referenced group.

This also adds `windowmanager` as a dependency of `blenkernel` to be able to
send notifiers.

This patch adds two new inputs to the Glare node, Highlights Smoothness
and Max Highlights. Smoothness allows the user to control how smooth the
highlights are after thresholding and Max allows the user to suppress
very high brightness pixels.
Those are essentially similar to the Knee and Clamp options in old EEVEE
bloom, though they work differently.
The issue with the Knee parameter in old EEVEE bloom, aside from being
named after a body part, is that it actually isn't smooth or continuous
around zero if the threshold is sufficiently close to zero relative to
the Knee parameter. That's because zero lies in the smoothing kernel
region in those cases, and since zero pixels becoming highlights is very
bad, EEVEE just returned zero as a special case for zero brightness, but
values like 0.0001 will be full blown highlights.
The new nicely named Smoothness input uses adaptive smoothing such that
the smoothing kernel size will be reduced as the threshold nears zero,
such that smoothed highlights will be continuous and smooth around zero.
The Max Highlights input is similar to clamped, it it suppresses very
bright highlights such that their brightness doesn't exceed the
specified max.
This is a partial implementation of #124176 to address #131325.

Two messages were not translatable because they used a string stored
in a variable, or an if/else expression.
One was translated when it should not have, because it prints the name
of a material.

The Warning geometry node uses its warning type as label. These enum
items were extracted using the default context, but translated using
"Nodetree". The items Warning, Info and Error, should be quite
unambiguous and translated using the default context instead.
In addition, a string "Unknown" was translated twice. Replace one of
those translations with a simple `N_()` extraction macro.
- "Strength" in the context of Grease Pencil, deals with opacity, and
adjusts the brush stroke alpha.
- "Strength" can mean measurable units like 'noise', 'light', etc.
- Anything else using physical strength in a generic concept.
Issue reported by Hoang Duy Tran.
- "Steps" can refer to staircase steps in the context of curve
profiles. Use already-extracted "Mesh" context.
- In the context of the Grease Pencil noise modifier, refers to a step
number between frames.
- In the general context, refers to a number of times to do an
operation.
Issue reported by Hoang Duy Tran.
- "Space" can be the spacebar key. This uses the UIEvents context
already. One instance is the event type enum item, where "Spacebar"
is the label and "Space" is the description. Since there is no way
to use contexts for descriptions since they are supposed to be more
verbose, the label was renamed to "Space Bar" (acceptable according
to Wikipedia), and the description to "Spacebar".
- In the context of the Grease Pencil, "Space" is a method of spacing
brush strokes.
Issue reported by Hoang Duy Tran.
"Smooth" can be many things, but mostly a verb or adjective depending
on context.
Already handled in the past, but some things were missed or introduced
since then.
"Sharp" can refer to a curve falloff, not a mesh edge's geometric
property.
For an existing enum property `Brush.curve_preset`, use the same
context ID_CURVE_LEGACY as other messages, instead of ID_CURVES.
Issue reported by Hoang Duy Tran.
- In the context of color balance, refers to a power function. Uses
ID_MOVIECLIP context, because the ID_NODE is already used for math
functions.
- In the context of the scale constraint, also a power function.
- In the context of physics and particle settings, refers to a
falloff.
- In the context of property subtypes and units, refers to a
quantity.
Issue reported by Hoang Duy Tran.
"Light" already has multiple contexts, but some were missing:
- In general, "Light" refers to a Blender Light object. In many cases,
this comes from an `id_type` enum, already using the ID context. Use
it also for properties that were missing that context.
- In the context of render passes, "Light" is the actual illumination
factor, not the light emitor. A new "Render Layer" translation
context is introduced for this purpose as no existing ones are both
specific and explicit enough.
Issue reported by Hoang Duy Tran.
- In the context of mesh extrusion, "Fill" means "Fill the rim of an
extruded edge loop" (verb).
- In the context of the file browser, it means select every file
between beginning and end.
- In the context of an image, fill the tile with generated image.
Issue reported by Hoang Duy Tran.
- "Extend" usually means making selection bigger around the current
one.
- In the context of Grease Pencil filling, it means lengthen lines.
- In the context of curve mappings, it refers to the extrapolation
mode.
- In the context of volume sequences, it refers to frame range
extension.
Issue reported by Hoang Duy Tran.
"End" in "Clip End" can be better translated to something like "Far"
in some languages. Using the "Camera" context even when it's not
specifically a camera clipping (also affects light probes).
Issue reported by Gorazd-Gorup.
- "Cross" can refer to a cross shape "+" in the context of a gizmo or
a particle display mode.
- In the context of a sequence, refers to a blending mode (cross
fade).
Issue reported by Hoang Duy Tran.
- In a text sequence, "Box" refers to the color rectangle behind the
text. Reuses the "Sequence" context already used for the same thing.
Issue reported by Gabriel Gazzán.
- In the context of Grease Pencil, meaning "Overshoot".
- In the context of XR navigation, meaning "Going backwards".
This introduces a "Navigation" context. Closest existing match is
"View3D" but this is already used to refer to view axes.
Issue reported by Hoang Duy Tran.
- In the Grease Pencil Build modifier, "Additive" describes how it
works, not a math operation.
- In the Copy Scale constraint, additive mode is not really a math
operation either.
Issue reported by Hoang Duy Tran.
- "Match Case" and "Wrap Around" were renamed but they do not need a
translation context anymore.
- Spreadsheet tooltips with unneeded translation of format
strings like `fmt::format(TIP_("{}"))`.
This works around ffmpeg bug https://trac.ffmpeg.org/ticket/10755
where for specific files that are:
- Ogg container format, with supported audio stream (e.g. Vorbis),
- But the video stream is not Ogg-compatible (e.g. Theora), but rather
it is an embedded "album art" (AV_DISPOSITION_ATTACHED_PIC) in
MJPEG, PNG or some other non-Ogg format.
Calling any sort of ffmpeg "seek" function on that video stream just
aborts from innards of ffmpeg.
So to work around this:
- Detect such files (ogg container, non-theora video, attached picture
disposition) and for those:
- Never seek within them, and only ever decode one frame. Return that
frame for any & all "give me a frame" requests.
- Additionally, calculating "how many frames this video has" for such
files also returns nonsense ("millions of frames") since their frame
rate is set to like 90000 or similar. So pretend they have a "sane"
frame rate. Do all this frame rate calculation just once when opening
the video, and use that result in all other places.
- Never build proxies for such video files, since e.g. "timecode"
for them does not make sense.
All of this could be removed once/if ffmpeg fixes their issue.

EEVEE material slots would be erroreously shown when there's no material

In order to copy vertex group weights when subdividing strokes the
groups (`bDeformGroup`) must be created in advance, so that the attribute
wrappers correctly write to `CD_MDEFORMVERT` layer instead of creating simple
`CD_PROP_FLOAT` layers.
In addition the subdivision function must take care to fully write the
destination arrays, since initial values must be considered uninitialized (this
is obfuscated for simple CustomData arrays but breaks with more complex
attributes that use a buffer). In order to ensure fully defined destination
buffers without additional copies, the `finish` call to attribute writers is
postponed until the unselected attribute values have also been copied from input
buffers and all the values are properly defined.

Only enable by default dynamic rendering local read on Qualcomm devices. NVIDIA, AMD and Intel
performance is better when disabled (20%). On Qualcomm devices the improvement can be
substantial (16% on shader_balls.blend).
`--debug-gpu-vulkan-local-read` can be used to use dynamic rendering local read on any
supported platform.
Future: Check if bottleneck is during command building. If so we could fine-tune this after the
device command building landed (#T132682).

This will add support for `VK_KHR_dynamic_rendering_local_read` when supported.
The extension allows reading from an attachment that has been written to by a
previous command.
Per platform optimizations still need to happen in future changes. Change will
be limited to Qualcomm devices (in a future commit).
On Qualcomm devices this provides an uplift of 16% when using shader_balls.blend
