The Smoke Surface Emission is the height of the smoke from the mesh surface.
It is measured in Domain Grid Units, and if the grid unit is relatively big
(compared to the mesh), the smoke emission is huge.
To fix that the Surface Emission was decreased from 1.5 to 1.0. As a result
it is possible to emit smaller smokes (width 2, previously 3).
Further decreasing default value of Surface Emission is not recommended,
as in some cases (too small mesh compared to Grid Unit) will result not
emitted smoke.
Fix#132613: Issue with large smoke domain and small emitter

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.

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

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.

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.

When creating a new action slot for a data-block, via the '+ New' button
of the slot selector, use the name of the slot that was last used by
that data-block. Previously, it would always use the name of the
data-block, interfering with slot auto-selection when toggling between
Actions.

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.

Ref: #132179
Renames:
- `Editing.act_seq` -> `Editing.act_strip`
- `SequenceModifierData` -> `StripModifierData`
- Its member `mask_sequence` is now `mask_strip`.
- `MetaStack.parseq` -> `MetaStack.parent_strip`
- Remaining function names/parameters that were not dealt with in #132748
- Various references to `seq` or `sequence` throughout code and docs when
referring to a strip
Also moves `_get` to the end of the renamed function names where
applicable for standardization (unless "by" or "from" are used).
There should be no changes to current behavior.

The "Make Panel Toggle" operator does not check if active item is an input socket,
leading to a situation where it can be called on Boolean output sockets.
Doing this creates weird behavior where the panel and associated
operators believe it has a toggle, but is not reflected in the UI drawing.
Other weird behaviors include being able to rearrange output sockets
and apply the operator again to another output socket.
This patch adds a check in the operator's poll function to prevent it
from being called on output sockets.

The "new/duplicate" button in the Action Slot selector did not actually
duplicate, and always acted as a "new" button.
This introduces the RNA function `ActionSlot.duplicate()`, which takes
care of duplicating all the animation data associated with the slot as
well. The semantics of this function should remain valid in the
future, when Actions support multiple layers & strips. Note that this
new function does not assign the slot, it just duplicates it and its
data. The assignment of this duplicated slot is done in Python,
through the already-existing API for this.

This implements bundles and closures which are described in more detail in this
blog post: https://code.blender.org/2024/11/geometry-nodes-workshop-october-2024/
tl;dr:
* Bundles are containers that allow storing multiple socket values in a single
value. Each value in the bundle is identified by a name. Bundles can be
nested.
* Closures are functions that are created with the Closure Zone and can be
evaluated with the Evaluate Closure node.
To use the patch, the `Bundle and Closure Nodes` experimental feature has to be
enabled. This is necessary, because these features are not fully done yet and
still need iterations to improve the workflow before they can be officially
released. These iterations are easier to do in `main` than in a separate branch
though. That's because this patch is quite large and somewhat prone to merge
conflicts. Also other work we want to do, depends on this.
This adds the following new nodes:
* Combine Bundle: can pack multiple values into one.
* Separate Bundle: extracts values from a bundle.
* Closure Zone: outputs a closure zone for use in the `Evaluate Closure` node.
* Evaluate Closure: evaluates the passed in closure.
Things that will be added soon after this lands:
* Fields in bundles and closures. The way this is done changes with #134811, so
I rather implement this once both are in `main`.
* UI features for keeping sockets in sync (right now there are warnings only).
One bigger issue is the limited support for lazyness. For example, all inputs of
a Combine Bundle node will be evaluated, even if they are not all needed. The
same is true for all captured values of a closure. This is a deeper limitation
that needs to be resolved at some point. This will likely be done after an
initial version of this patch is done.

Add support for a 5th modifier key called "hyper",
this is a modifier supported on Wayland & X11 although
other platforms could support an additional modifier too.
Both GNOME and KDE can map CapsLock to Hyper.
Other compositors can use the XKB_DEFAULT_OPTIONS environment variable.
This allows users to have an additional modifier for their own use
that doesn't conflict with other keys.

The poll functions for: VIEW3D_OT_edit_mesh_* operators only checked
for an edit-mode object which failed with an unhandled exception for
non-mesh objects.
Implement shortcuts for viewer nodes. Viewer nodes are now activated using the operator `bpy.ops.node.activate_viewer()` instead of activating the viewer by setting the node to active.
This also unifies the behavior with viewer shortcuts in the compositor (see attachment in the original PR).

Adds the option to create a boolean socket that can be used as a panel toggle.
This allows creating simpler and more compact node group UIs when a panel
can be "disabled".
The toggle input is a normal input socket that is just drawn a bit differently in
the UI. Whether a boolean is a toggle input or not does not affect evaluation.
Also see #133936 for guides on how to add and remove panel toggles.

This happened for context attributes if already "complete" attributes
were typed/pasted in.
Reason is that this copies functionality from our intellisense
codecompletion where this is expected behavior, for context attributes
we cannot really use "tab" to expand, so it is less useful here.
When confirming (with the additional "."), the keymap entry would be
broken, so better solve in a way that we dont end up with those "." by
removing it.
NOTE: there might be ways to enhance the string-search behavior here (by
properly supporting "tab-expanding"), but this is a bit out-of-scope for
this bugfix.

Use the new `action.fcurve_ensure_for_datablock()` function to ensure
the opacity F-Curve exists.
This function also ensures that the Action itself is ready for keying
(it has a layer and a keyframe strip), and ensures the slot for the
Scene exists and is assigned.
