This adds a new Bit Math node which supports the following operations: `and`,
`or`, `xor`, `not`, `shift` and `rotate`.
For the `shift` and `rotate` operations, a posititive shift is a left shift and
a negative shift is a right shift.
Currently, the node always works on 32-bit integers which is what Geometry Nodes
uses internally for integers. If required, this can be extended to work on other
bit widths in the future.
The need for this came up every now and then. It can be useful when encoding
specific bits in integer attributes (for efficiency or because the geometry is
exported to other software that expects a certain format). Also, this node is
useful for some people doing crazy but fun things with Geometry Nodes like
emulating hardware. Even if the use-cases are not common, if they arise, it's
hard to work around and the cost of having this node is quite low for us.

The modifier input value for menu items is an int property, which is not
compatible with the enum property used in node group socket definitions for
menus. Wrapping a node group with a menu will try to assign the int value from
the modifier directly to the enum, which expects a string identifier.
To aquire the matching string identifier, use the UI properties in the modifier
RNA, which contain the complete enum item definition.

Previously, when adding a group node it was always called `Group`. This is not
particularly useful. Also it's inconsistent with many other places like adding
modifiers where the name of the modifier depends on what modifier is added.
Now, newly added group node will have the same name as the group that it calls.
Node names still have to be unique though, so e.g. `.001` is still added.

Always show the 'Available' option in the keyframe menu, so that the
shown menu items are stable. This helps to keep hotkey assignments for
the menu items remain the same.
Note that this isn't a full guarantee yet, as the 'Active Keying Set'
option is also still conditionally added, depending on whether a
keying set was chosen or not. This will be addressed in another
commit.

Armature bone display mode (Octahedral, Stick, Envelope, B-Bone,
Wire) could only be set on the whole armature. This adds ability to
override the display mode per-bone (by default bones use the
same display mode as the armature).

At this point, with pen tilt functionality having received the following
changes recently:
* Consistency between platforms for what pen tilt values represent
* Inactive cursor visualization
* Invertable per-brush strength
The majority of the work that remains is wider testing and addressing
per-device issues, thus it makes sense to make this option available in
release builds.
By default, no brushes packaged with Blender have a non-zero Tilt
Strength, making this option opt-in by default.
The following brushes support this option:
* Draw
* Draw Sharp
* Flatten
* Fill
* Scrape
* Plane
* Clay Strips
With a non-zero Tilt Strength value on the brush, the normal of the
brush plane is tilted in the same direction as the user's pen, where a
perpendicular orientation for the pen matches the behavior with a Tilt
Strength of 0.

Previously, one had to search for "Time" to get the Scene Time node which
provides access to the current frame and second. Intuitively I often start
searching for "frame" or "seconds" instead and only later remember what I
actually have to search for.
This patch improves the UX by allowing to create a Scene Time node by searching
for "frame" or "seconds" directly. This works in Geometry Nodes and the
compositor.

Currently, depending on whether or not a brush asset is part of a
library, the context menu shown for it changes significantly.
To better support local brush asset modifications, and make the UI more
consistent, this commit exposes the following operators:
* `brush.asset_edit_metadata`
* `brush.asset_load_preview`
* `brush.asset_save`
* `brush.asset_revert`
Of these four operators, the first two are allowed to execute, whereas
the latter two are always disabled on local assets via the corresponding
`poll` methods, as neither is applicable for this usecase.

The current behavior for the Node Editor's Add menu is to list the
user's asset catalogs at the root level of the menu. However, an
exception is made if the catalog has the same name as a builtin menu.
In such case, the asset catalog is appended to that builtin menu,
instead of being drawn at the root level.
How this is currently implemented right now is to have a hard-coded set
of builtin menus in `add_menu_assets.cc`. Certain menus are missing from
this set, particularly newer ones, which may be an oversight during the
creation of these menus.
This patch adds those menus to that list, which are as follows:
- Input/Gizmo
- Input/Import
- Grease Pencil (and all its submenus)
- Texture (in Compositor Nodes)

Previously, the modifier name was used to identify it in a compute context or
viewer path. Using `ModifierData.persistent_uid` (which was only introduced
later) has two main benefits: * It is stable even when the modifier name
changes. * It's cheaper and easier to work with since it's just an integer
instead of a string.
Note: Pinned viewer nodes will need to be re-pinned after the change.

Rework internals of how VSE caching is done. Primarily to make all the
caching logic more understandable from development point of view, but
also has several user visible implications (more details in the PR):
- Simpler and fewer caching UI options,
- Disk cache is gone (primary reason: proxies are kinda the same thing),
- VSE cache size set in preferences is actual size used for VSE caches
now (previously caching stopped as soon as whole Blender used that
much memory, even if some memory usage was not about VSE at all),
- Certain scenarios of cache invalidation are faster now.

Prior to this commit, the Dyntopo panel was hardcoded to display as
faded if the current brush was the mask brush. This conflicts with the
common set of brushes which we do not support dyntopo for, which
includes many other brushes.
This commit changes the check to better indicate that certain brushes do
not support dyntopo. The scene-level settings can still be changed & the
detail flood fill operator remains functional even if the a different
brush is selected.
Additionally, the panel is no longer greyed out if the "Manual" option is
active.

These are generic properties of grids (not stored in voxels) which are
useful to know in geometry nodes. The transform in particular defines
the voxel size. Background value is used outside of active voxels.

There are two implementations:
- "Link to Viewer Node"
-- when clicking on a socket directly, link from that socket [done by
first selecting and then taking that selection state into account]
-- otherwise cycles through available sockets
- "Connect to Output" [python operator, made core from Node Wrangler]
-- does not take socket selection into account
-- only cycles through available sockets
So goal is to replicate behavior of "Link to Viewer Node" in "Connect to
Output" in terms of "which socket to link from"
This is done by
- exposing a sockets select state to python
- tweaking the call to bpy.ops.node.select so it does socket selection
as well
- take that selection into account

As described in #122398, implement read and write support for a new
attribute storage system. Currently this is only implemented to support
forward compatibility; the format used at runtime isn't changed at all.
That can be done one step at a time during the 4.5 and 5.0 development
cycles. A new experimental option for testing tells Blender to always
save with the new format.
The main benefit of the new structure is that it matches the attribute
system design, it allows for future attribute storage optimization, and
each attribute is an allocated struct, which will give pointer stability
for the Python API.
The next step is to connect the attribute API and the RNA API to
AttributeStorage for the simplest geometry type, point clouds.

The main way to create a new node group right now is to select some nodes and
then press ctrl+G. This works well for the common case when one already has some
nodes to group. However, there is no good alternative currently for when one
wants to create a new group from scratch. A common workaround currently is to
add some dummy node, then press ctrl+G and then to delete the dummy node in the
group again. Obviously, we can do better than that.
This patch adds a `New Group` entry in the menu. It's available in geometry,
compositing and shading Nodes. The operator adds a new node group called
"NodeGroup" (the same default name we use for ctrl+G currently). Then it adds a
new group node and assigns the new group to it. The group itself does not have
any inputs or outputs by default because any such socket would just be a guess
that's likely wrong and more annoying than useful.
A nice side benefit of adding this operator is that the Group menu is not empty
in shading and compositing nodes initially which always looked a bit off.

Previously, it was possible to search for specific math operations in
link-drag-search but not in the normal add menu. This patch adds support for
searching for specific operations in various math nodes.
A good trick for adding e.g. a vector add node is to search for `vadd`
(similarly with `iadd`).
The menu itself looks unchanged. This patch only adds additional elements to the
search.

It always was functionality which got committed without proper review
by the module or UI/UX team. It has all sort of UX problems, but it is
also something that will be tricky to support for HDR drawing.
To brings things to a more manageable state the functionality is now
removed.
With `MESH_OT` prefix, the shortcut was added to wrong
keymap ("object mode", see: `WM_keymap_guess_opname`).
idname of following operations has been changed, they are

Previously sync-select in edge-select mode behaved in much the same
way as vertex selection, since a selected edge could cause a vertex
on an a disconnected UV island to be selected.
Now single vertices are no longer considered selected when the
Sticky-Mode is set to "Location" (the default).
Notes on changes when sync-select is enabled:
- The main change from a user perspective is edge & face select modes
show the selected edges.
- This resolves a problem in edge & face selection modes where it wasn't
possible to differentiate between a selected edge and two selected
vertices on either side of an unselected edge.
This adds an Import VDB node. It loads all the grids from a .vdb file and hence
outputs a Volume geometry instead of an individual grid.
The grids are cached through the existing volume grid file cache, so they are
automatically deduplicated when volume grids are loaded from files in other
ways.

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.

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.

I'm not sure when this stopped working. The function in question is
quite confusing since it's called twice with two different purposes.
Fixing the exception is simple though. Just checking the data type
for "None" prevents changing the data type to one that's invalid given
the context. I didn't find a simple way to add an error message though.

Allow assign/select operators to execute when armature tab is pinned.
For assign operators, pinned armature should be active in 3D view
because we cannot assign bones of one armature to the bone collection of
different armature. Added extra condition in poll function to control

For select operators, use `ED_armature_context` to obtain pinned Armature.
These operators are now hidden in object modes.

Part of #135062.
This PR adds an Auto Normalize option in the Vertex Group panel that
when checked will normalize the other deform-bone vertex groups' weights
when assigning the weight of a deform-bone vertex group. For example if
a selected vertex has the following weights:
| Name | Weight |
|---------|--------|
| Group 1 | 0.2 |
| Group 2 | 0.2 |
| Group 3 | 0.6 |
And the user selects Group 3, checks the Auto Normalize checkbox, sets
the weight to 0.8, and clicks Assign, the new weights will be:
| Name | Weight |
|---------|--------|
| Group 1 | 0.1 |
| Group 2 | 0.1 |
| Group 3 | 0.8 |
