I'd like to use this file to draw curves from geometry nodes, which
would otherwise require implementing a C API. The changes in this
commit are minimal, mostly just casts and changing to nullptr.

Since version 2.80, the annotations of the Scene strip were not displayed in VSE. Also, the UI panel was`Grease Pencil` and must be `Annotation`
The problem was the offscreen render hasn't evil_CTX and the section of the annotation was never called.

This commit allows that the evaluated geometry of an object has
different materials from the original geometry. This is needed
for geometry nodes.
The main thing that changes for render engines and exporters
is that the number of material slots on an object and its geometry
might not match anymore. For original data, the slot counts are
still equal, but not for evaluated data.
Accessing material slots though rna stays the same. The behavior
adapts automatically depending on whether the object is evaluated.
When accessing materials of an object through `BKE_object_material_*`
one has to use a new api for evaluated objects:
`BKE_object_material_get_eval` and `BKE_object_material_count_eval`.
In the future, the different behavior might be hidden behind a more
general C api, but that would require quite a few more changes.
The ground truth for the number of materials is the number of materials
on the geometry now. This is important in the current design, because
Eevee needs to know the number of materials just based on the mesh in
`mesh_render_mat_len_get` and similar places.
In a few places I had to add a special case for mesh edit mode to get it
to work properly. This is unfortunate, but I don't see a way around that
for now.

This was a bug uncovered by rB50782df42586.
Previously, the lightcache was always discarded between redraw and forced
to be updated again.
Now we check for update inside the render loop making it compatible with
accumulation motion blur and long exposure.
This was caused by the slight focus gather not being wide enough
for small radii. Now the cast to int will properly round the radius to
the nearest integer.
This is related to T86244 Black Artefacts in EEVEE on Transparent BSDF
This was caused by the bokeh LUT being sampled outside the valid range.
But `texelFetch` is only valid if the sample actually exists. This lead to
undefined behavior.
The fix is to increase `DOF_MAX_SLIGHT_FOCUS_RADIUS` (which just offsets the
LUT along the X=Y axis) to avoid any sample outside the defined range.
This was caused by the drivers not optimizing the shader enough to remove
the samplers and data used by closure eval. Removing the lighting loops
from the depth shader fixes the perf regression.
Add translation/rotation/scale parameters for custom bones shapes. The
new scale is a 3D vector `custom_shape_scale_xyz`, and replaces the
`custom_shape_scale` float.

This enables the overlay for instanced geometry.
After this change, objects that are an instance of the current active
object (which are also being modified in the current active mode) won't
fade, which is different from the previous behavior.

When a scene uses cryptomatte the viewport rendering would lead to a
memory leak. The reason was that all image renders (viewport+final)
activated cryptomatte. But is only used for final rendering.
This patch only activates cryptomatte when doing final rendering.
This was caused by the SSR option resetting the accumulation. But the
render passes were only cleared in the init phase. This means that
when SSR was resetting the `taa_render_sample` the actual renderpasses
would still contains 1 sample. This means the renderpasses were always
divided by the wrong number of samples.
The fix is to clear just before accumulation if the sample is 1.
The fact that it works for motion blur is kind of a blessing. This is because
we check `stl->effects->ssr_was_valid_double_buffer` before resetting the
sampling. So this only happens on the first motion step and does not affect
the rest of the rendering.

This artifact was already present in previous version but was hidden
by the faulty SSS scale.
The issue comes from the translucence using the geometric normal
(computed using fragment shader derivative) leading to poor precision at
depth discontinuity.
Replacing using the same geometric normal reconstruction as the ambient
occlusion pass removes most of the issue.

Some discard of vertbuf were not correctly followed by discards of
the GPUBatches that were using them. This lead to a use-after-free
situation where GPUBatches would reuse old VBO information. This did
not crash immediatly because the VBO indices were cached by our VAO
caching system. It kept working on some implementation because VBO
reference in the VAO (probably) preventing the VBO from being freed
by reference counting.

This was caused by the new depsgraph persistence.
The GPUbatches we got from the cache being the same for each frame
means that we need to be more careful about cleanning the additional
VBOs references.
Moving the `EEVEE_motion_blur_swap_data` function call at the end of
the loop makes sure the references are cleaned.
In cases where the same node tree is used in different materials with
small changes, the wrong material could be selected.
Cause: Hair shaders GPU resources weren't updated and used the previous bound data.

The UV factor of the last point of a cyclic stroke was using the factor of

Now, instead to offset the stroke color to make it visible over fill, the stroke keeps the original color and the fill is offset.
Related to the issue in T87406.
The color of the strokes was shifted when using `Single Color` or
`Object Color`in Solid Display Mode. This was originally done so
that it was still possible to differentiate strokes and fills.
The fix allows for a completly flat shading by checking if the
Lighting Mode is set to `Flat`. If it is, then the colors are not
shifted for the strokes and everything will use the same color.

The problem was that you could getting write access to a grid from a
`const Volume *` without breaking const correctness. I encountered this
when working on support for volumes in the bounding box node. For
geometry nodes there is an important distinction between getting data
"for read" and "for write", with the former returning a `const` version
of the data.
Also, for volumes it was necessary to cast away const, since all of
the relevant functions in `volume.cc` didn't have const versions. This
patch adds `const` in these places, distinguising between "for read"
and "for write" versions of functions where necessary.
The downside is that loading and unloading in the global volume cache
needs const write-access to some member variables. I see that as an
inherent problem that comes up with caching that never has a beautiful
solution anyway.
Some of the const-ness could probably be propogated futher in EEVEE
code, but I'll leave that out, since there is another level of caching.
