Besides texture nodes, which aren't supported anyway, we don't have any
builtin nodes that still use the socket template system, so this can be
removed.
This change is part of a wider set of changes to implement Grid and Pixel
snapping in the UV Editor. This particular change adds a new third option,
`pixel grid`, to the previous grid options, `dynamic grid` and `fixed grid`.

A refactor of the margin calculation of UV packing, in anticipation
of multiple packing methods soon becoming available.
Three margin scaling methods are now available:
* "Add", Simple method, just add the margin. [0]
(The default margin scale from Blender 2.8 and earlier.)
* "Scaled", Use scale of existing UVs to multiply margin.
(The default from Blender 3.3+)
* "Fraction", a new (slow) method to precisely specify
a fraction of the UV unit square for margin. [1]
The "fraction" code path implements a novel combined search / secant
root finding method which exploits domain knowledge to accelerate
convergence while remaining robust against bad input.

* 'Original coordinates' mode can't be used in image paint mode
(it does nothing in this case anyway).
* SCULPT_automasking_factor_get now returns 1.0 if
a PBVH_REF_NONE vertex reference is passed in.
Do not save the "use_proportional_edit" property if it is not supported.
This prevents it from being automatically disabled.
And hide "use_proportional_edit" in `SPACE_NLA`

The parallel reduction file didn't include its own header, which can
yield "no previous declaration" warnings. This patch includes the header
to fix the warning.
This patch implements the variable size blur option in the Bokeh Blur
node. The implementation is different from the CPU one in that it also
takes the Bounding Box input into account, which is ignored for some
reason for the CPU. Additionally, this implementation does not do the
optimization where the search radius is limited relative to the maximum
value in the size texture. That's because the cost of computing the
maximum is not worth it for most use cases.
The reference implementation does three unexpected things that are
replicated here nonetheless. First, the center bokeh weight is always
ignored and assumed to be 1. Second the size of the center pixel is
taken into account. Third, a unidimensional distance is used instead of
a 2D euclidean one. Those need to be considered independently.

The crash was caused by [0] however knife-project functionality has been
incorrect since [1] which would loop over each edit-mode object and run
the knife project function which operated on all edit-mode objects too.
- Resolve the crash by postponing face-tessellation recalculation
until the knife tool has cut all objects
- Objects occluding each other is now supported
(an old TODO and something that was never supported).

Cleaned up Dyntopo original triangle API (which is deprecated):
* BMVerts for original triangles are now stored.
* BKE_pbvh_bmesh_update_topology now handles original triangle
* data properly.
* BKE_pbvh_bmesh_node_save_orig can now initialize the original
coordinates from the current BMLogEntry.
* Ray casting of original data now returns active vertex.
Should fix various random crashes.
Hopefully this will fix a number of bugs.
Cleaned up sculpt_face_sets_change_visibility_exec some more:
* SCULPT_UNDO_HIDDEN is now pushed instead of SCULPT_UNDO_FACE_SETS
(since face sets no longer encode visibility).
* Added branches for if face sets do not exist.
* Cleaned up independent if statements into a switch.
The confusion is about World as an ID type, and the World coordinates.
Use no context for the latter, and either `BLT_I18NCONTEXT_ID_WORLD`,
or other more fine-grained contexts when needed as part of enums for the
former.
The message from the custom HDRI installation operator cannot be
disambiguated right now, because Python enums don't support contexts.

Refactor the `recalcData_nla()` function, which takes data from the
transform system and updates NLA strips, such that the actual logic to
change the strip is moved into its own function.
This also moves some generic code (find prev/next strip) from that
function to BKE.
This is to make the code easier to adjust when different transform
operations need to perform different modifications of the strip (i.e. to
fix T101130).

Part of T101073: after the view layer sync was made lazy (D15885), the
BKE_layer_collection_resync_forbid and BKE_layer_collection_resync_allow
in Alembic/USD/OBJ importers is no longer needed, as long as they do
view layer dependent operations (selecting new objects) in a separate
loop after creating all the objects.
Verified that this does not regress import times for 26k objects OBJ
scene (Blender 3.0 splash) and 250k objects USD scene (Moana).
When calling `wm.call_menu_pie` and `wm.call_menu`, the menu context
was ignored when showing its name in the header or pie menu center.

Show the windowing environment on non MS-Windows/Apple systems,
since X11/WAYLAND are selected startup there was no convenient way
for users to know which back-end was being used.
Include the windowing environment in the About splash & system-info.txt
since it will be useful for handling bug reports.
This commit adds a private API call not intended for general use
as I would like to be able to remove this later and it's only needed
in the specific case of testing if Blender is using WAYLAND or X11
(which maybe be used via XWayland).
Python scripts can already inspect the system to check which windowing
environment used, the API call is mainly useful for troubleshooting.
The importer logic was wrongly resetting "current material name"
upon encountering a new object ("o" command). However as per OBJ
specification, this is incorrect:
> Specifies the material name for the element following it. Once a

> changed.
Fixes T101685. Test coverage for this was added in svn tests repo.

The attribute node already allows accessing attributes associated
with objects and meshes, which allows changing the behavior of the
same material between different objects or instances. The same idea
can be extended to an even more global level of layers and scenes.
Currently view layers provide an option to replace all materials
with a different one. However, since the same material will be applied
to all objects in the layer, varying the behavior between layers while
preserving distinct materials requires duplicating objects.
Providing access to properties of layers and scenes via the attribute
node enables making materials with built-in switches or settings that
can be controlled globally at the view layer level. This is probably
most useful for complex NPR shading and compositing. Like with objects,
the node can also access built-in scene properties, like render resolution
or FOV of the active camera. Lookup is also attempted in World, similar
to how the Object mode checks the Mesh datablock.
In Cycles this mode is implemented by replacing the attribute node with
the attribute value during sync, allowing constant folding to take the
values into account. This means however that materials that use this
feature have to be re-synced upon any changes to scene, world or camera.
The Eevee version uses a new uniform buffer containing a sorted array
mapping name hashes to values, with binary search lookup. The array
is limited to 512 entries, which is effectively limitless even
considering it is shared by all materials in the scene; it is also
just 16KB of memory so no point trying to optimize further.
The buffer has to be rebuilt when new attributes are detected in a
material, so the draw engine keeps a table of recently seen attribute
names to minimize the chance of extra rebuilds mid-draw.
