The node warnings were only referenced by the tooltip function. Since they are
recreated on every evaluation, this resulted in a use-after-free. The fix is to
just copy the node warnings into the callback.
Of course this extra copy does have some performance implications, but I don't
think those are significant currently.

This renames UI_block_layout API as blender::ui::block_layout_resolve,
following uiLayout refactors.
This simplifies usage by returning block layout size as C++ int2 instead
of using return parameters, in fact some places were providing
unused variables.

Node socket tooltips can include substrings from many different
sources. This commit adds two that were previously untranslated:
- hardcoded strings that simply need to be manually translated using
`TIP_()`,
- the socket name, which should use its context. This simply copies
the translation code from the socket name label.
Reported by Gabriel Gazzán in #43295.
This renames `UI_block_layout` API as `blender::ui::block_layout`,
following uiLayout refactors.
This function now returns a layout reference instead of pointer,
this changes applies this return type where the layout can be used
as such reference.
Changes includes the use of `blender::ui::LayoutDirection` and
`blender::ui::LayoutType` as typed enum parameters.

This removes the include `UI_interface_layout.hh` from
`UI_interface_c.hh`, and in many places this swaps the include
from `UI_interface.hh` to `UI_interface_layout.hh`.
Also, cleanups some `UI_interface.hh` includes with
`UI_interface_icons.hh` or `UI_interface_types.hh`
This replaces uiLayout aligment API with uiLayout methods,
following uiLayout refactors and the Python API naming.
Also this converts the layout aligment enum to a fixed enum class.

Make node headers (or body when collapsed) use the exact theme color
set for that node type, instead of a hardcoded blend between it and the
node backdrop.
This can result in unreadable combinations, but allows more
flexibility and it is consistent with the rest of Blender.
Both dark and light theme defaults have been updated.

This is part of the short term roadmap goal of simplifying the
compositor workflow
(see https://projects.blender.org/blender/blender/issues/134214).
The problem is that many users don't know how to get started with
compositing in Blender, even when they have used Blender for other
areas, e.g. modeling.
Note: although the solution makes compositor node trees reusable
accross blend files, this is a nice side effect and not the main goal
of the PR.
This PR implements a "New" button that creates a new compositing node
tree, and manages trees as IDs. This has following advantages:
- Consistent with other node editors and other parts of Blender,
therefore making it easier to getting started with compositing if users
are familiar with shading or geometry nodes
- Give users the ability to reuse the compositing node tree by linking
or appending it.
Note: The parameter "Use Nodes" is still present in this PR, but will
be removed (in a backward compatible way) in a follow up PR.

This prevents the use of unaligned data types in
vertex formats. These formats are not supported on many
platform.
This simplify the `GPUVertexFormat` class a lot as
we do not need packing shenanigans anymore and just
compute the vertex stride.
The old enums are kept for progressive porting of the
backends and user code.
This will break compatibility with python addons.

Implementation of #127106.
This is just a visual representation of the field/single/grid
status of sockets to make the workflow more intuitive. With
a visual representation for volume grid sockets, volume features
should be unblocked for further development. The structure type
will also be used to distinguish list sockets in the interface.
Group input nodes now have a "Structure Type" option instead of
the existing "Single Value Only". Usually the auto option should be
enough, but in some cases where the inferencing cannot (yet) make
a clear determination, it can be helpful to choose a specific type.
The new visualization and the group input structure type option
are hidden behind a new experimental option for now.

Nowadays, Geometry Nodes is not only evaluated by a modifier, but also by an
operator and in the future potentially by brushes. Therefore, the old name was
misleading because it sounded like it was specific to the modifier.

Node sockets have many different aspects that affect their visibility and
whether they are grayed out. This patch cleans up the methods used to check if
sockets are visible and adds descriptions that should make it more obvious which
ones should be used.
This also fixes a few places where the wrong method was used which is more
obvious now.

Node UIs can now have panels. Some of those may need to have their
labels translated using translation contexts. PanelDeclarations
already had a translation_context member, this commit adds a way to
specify this context, and to use it for translation on drawing the
node.
Pull Request: https://projects.blender.org/blender/blender/pulls/139124
Blender crashes when a node has a panel whose children input sockets are
all unavailable. This happens when marking sockets as collapsed, where
the non-initialized header_center_y members of such panels are accessed,
causing asserts or crashes.
The update_collapsed_sockets_recursive function has a check that should
avoid such accesses, but it seems wrong due to the negation of the
visibility check.
To fix this, we move the visibility check to a guard condition in the
marking function instead, and simplify the collapsed check in the update
function.

Previously, whenever the zone detection algorithm could not find a result, zones
were just not drawn at all. This can be very confusing because it's not
necessarily obvious that something is wrong in this case.
Now, invalid zones and links that made them invalid have an error.
Note, we can't generally detect the "valid part" of zones when there are invalid
links, because it's ambiguous which links are valid. However, the solution here
is to remember the last valid zones, and to look at which links would invalidate
those. Since the zone-detection results in runtime-only data currently, the
error won't show when reopening the file for now.
Implementation wise, this works by keeping a potentially outdated version of the
last valid zones around, even when the zone detection failed. For that to work,
I had to change some node pointers to node identifiers in the zone structs, so
that it is safe to access them even if the nodes have been removed.

This merges the public `uiItemS` and `uiItemS_ex` functions into an
object oriented API (`uiLayout::separator`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code
(or vice-versa), making it almost seamless.

Removes an inconsistency where sometimes `bke::node_label` is used and sometimes
`node.label` to get the frame label.
Consolidates several duplicated formulas for computing the frame layout into a

There are very rare use-cases for having multiple Group Output nodes. However,
it's something that's been supported for a long time and removing it may be a
regression for some. In practice, it's usually a mistake when someone has
multiple Group Output nodes.
This patch adds a simple warning on inactive Group Output nodes to help the user
notice this case.

Previously, it was somewhat difficult to know if a dragged node will be attached
to a frame or not. This patch highlights the frame that dragged nodes will be
attached to which removes the guesswork. This is similar to how we highlight the
link that a dragged node will be inserted onto.
Pull Request: https://projects.blender.org/blender/blender/pulls/138648
Previously, nested frames were very hard to see and therefore to work with. This
patch solves this by alternating between two different frame colors depending on
the nesting depth.
Custom colors can still be used like before. There is still a single theme
option. The alternating color is derived from that.
Pull Request: https://projects.blender.org/blender/blender/pulls/138649
Previously, the outline of frames was sometimes unexpectedly invisible.
The solution is to draw the frame outlines together with the zone outlines
after all the zone and frame backgrounds have been drawn already.

The idea here is to use `UI_but_func_tooltip_label_set` which has a shorter
duration until the tooltip shows (besides also being easier to use). It does
seem like it makes sense to use it here, because the only purpose of the error
icon is to hover over it. Therefore, one shouldn't have to wait for long until
the tooltip shows.

Previously, we had shown link errors on the target node as part of the node
warning system. While better than not showing any information about invalid
links (as was the state before that), it's still not ideal because it's easy to
miss when just looking at the link.
This patch adds an error icon in the middle of the invalid link. When hovering
over it, it shows the error text. When the middle of the link is not in view but
part of the link is, then the error icon will also stay visible.
Pull Request: https://projects.blender.org/blender/blender/pulls/138529
A frame label that is hidden by links is not all that helpful.
On the other hand, if a link is partially hidden by a frame label,
that's typically not a problem at all.
This converts the public `uiLayoutRow` function to an object oriented
API (`uiLayout::row`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code (or vice-versa),
making it almost seamless.
`uiLayout::row` now returns an `uiLayout` reference instead of a pointer.
New calls to this method should use references too.

Currently, clicking on the viewer icon in the compositor has no effect,
whereas in geometry nodes it activate or deactivates the viewer.
The compositor requires exactly one viewer to be active. So pressing the
icon when the viewer is already active has no effect
Pull Request: https://projects.blender.org/blender/blender/pulls/137840
Viewer nodes in compositor now show the eye icon when they are active,
so after https://projects.blender.org/blender/blender/pulls/134949
both geometry nodes viewers and compositor viewers look the same.
The only remaining difference is that in geometry nodes, clicking on
the eye icon deactivates the viewer and the node tree output
is shown instead. This is not possible in the compositor currently,
because at least one viewer must be active in the node tree.
Pull Request: https://projects.blender.org/blender/blender/pulls/134417
For consistency with other parts of Blender, the geometry visibility in the viewport is controlled by the viewport icon. The compositor will still have the eye icon for previews, but viewer nodes will get the viewport icon, also for consistency reasons.

This adds a simple `compute_context_for_edittree` function that returns the
"active" compute context for the given node editor. This is used in various
places, but previously one had to construct the compute context in multiple
steps (first find the root context (modifier/operator), then handle the tree
path). Since the edittree already has a specific active context, there should be
an easy way to retrieve that.
This also adds a few extra check that avoid redundant work that was done before.
Pull Request: https://projects.blender.org/blender/blender/pulls/137525
While `ComputeContextBuilder` worked well for building simple linear compute
contexts, it was fairly limiting for all the slightly more complex cases where
an entire tree of compute contexts is built. Using `ComputeContextCache` that is
easier to do more explicitly. There were only very few cases where using
`ComputeContextBuilder` would have still helped a bit, but it's not really worth
keeping that abstraction around just for those few cases.
