In heavy scenes containing many hairs/curves and volumetrics
using SSBO can overwrite the binding information of the volumetric
resolve shader. This has been detected during project Heist and is
only reproducable on NVIDIA platform.
This patch adds an debug option to disable SSBOs from the command
line to replace the --debug-gpu-force-workarounds that has been
used as a workaround on the render farm. Reason is that
force workarounds will also add other limitations as well (number
of texture binds for example)
Depending on the actual platform, Blender will disable features that are
known to have a faulty implementation. Add-on developers or users don't
have the ability to check what is actually enabled.
This patch will add the ability to check for
* Compute shader support `gpu.capabilities.compute_shader_support_get()`.
* SSBO support `gpu.capabilities.shader_storage_buffer_objects_support_get()`.
* Image load/store `gpu.capabilities.shader_image_load_store_support_get()`.
Refactor of `BLF_boundbox_foreach_glyph` and simplification of its
usage by only passing translated glyph bounds to callbacks.

Previously, all implicit inputs where stored in a centralized place.
Now the information which nodes have which implicit inputs is
stored in the nodes directly.
Previously removing elements based on a predicate was a bit cumbersome,
especially for hash tables. Now there is a new `remove_if` method in some
data structures which is similar to `std::erase_if`. We could consider adding
`blender::erase_if` in the future to more closely mimic the standard library,
but for now this is using the api design of the surrounding code is used.

When adapting the domain of a single value virtual array, skip
allocating an array for the result and just return another single
value. Among other cases, this can help when everything is selected
in sculpt mode, moving domain interpolation from 5% of perf samples
to 0% when sculpting.

bdb5754147 neglected to add search items for node groups.
Luckily adding them is quite simple. However, if the node group is also
an asset, it will show up duplicated in the list. To resolve this we
avoid adding node groups to the list if they have already been
added as assets.
This patch replaces the existing transfer attribute node with three
nodes, "Sample Nearest Surface", "Sample Index", and "Sample Nearest".
This follows the design in T100010, allowing for new nodes like UV
sampling in the future. There is versioning so the new nodes replace
the old ones and are relinked as necessary.
The "Sample Nearest Surface" node is meant for the more complex
sampling algorithms that only work on meshes and interpolate
values inside of faces.
The new "Sample Index" just retrieves attributes from a geometry at
specific indices. It doesn't have implicit behavior like the old
transfer mode, which should make it more predictable. In order to not
change the behavior from existing files, the node has a has a "Clamp",
which is off by default for consistency with the "Field at Index" node.
The "Sample Nearest" node returns the index of the nearest element
on a geometry. It can be combined with the "Sample Index" node for
the same functionality as the old transfer node. This node can support
curves in the future.
Backwards compatibility is handled by versioning, but old versions can
not understand these nodes. The warning from 680fa8a523 should make
this explicit in 3.3 and earlier.
