Just like the curve to points node, this mode outputs point locations
based on the input curve's evaluated points (the points you see in the
viewport). This is expected to be faster, since it doesn't have to
sample equal positions on the result, and it's also consistent with
the existing choices in the curve to points node.

This implements the initial core framework for fields and anonymous
attributes (also see T91274).
The new functionality is hidden behind the "Geometry Nodes Fields"
feature flag. When enabled in the user preferences, the following
new nodes become available: `Position`, `Index`, `Normal`,
`Set Position` and `Attribute Capture`.
Socket inspection has not been updated to work with fields yet.
Besides these changes at the user level, this patch contains the
ground work for:
* building and evaluating fields at run-time (`FN_fields.hh`) and
* creating and accessing anonymous attributes on geometry
(`BKE_anonymous_attribute.h`).
For evaluating fields we use a new so called multi-function procedure
(`FN_multi_function_procedure.hh`). It allows composing multi-functions
in arbitrary ways and supports efficient evaluation as is required by
fields. See `FN_multi_function_procedure.hh` for more details on how
this evaluation mechanism can be used.
A new `AttributeIDRef` has been added which allows handling named
and anonymous attributes in the same way in many places.
Hans and I worked on this patch together.

Previously, the Point Instance node in geometry nodes could only instance
existing objects or collections. The reason was that large parts of Blender
worked under the assumption that objects are the main unit of instancing.
Now we also want to instance geometry within an object, so a slightly larger
refactor was necessary.
This should not affect files that do not use the new kind of instances.
The main change is a redefinition of what "instanced data" is. Now, an
instances is a cow-object + object-data (the geometry). This can be nicely
seen in `struct DupliObject`. This allows the same object to generate
multiple geometries of different types which can be instanced individually.
A nice side effect of this refactor is that having multiple geometry components
is not a special case in the depsgraph object iterator anymore, because those
components are integrated with the `DupliObject` system.
Unfortunately, different systems that work with instances in Blender (e.g.
render engines and exporters) often work under the assumption that objects are
the main unit of instancing. So those have to be updated as well to be able to
handle the new instances. This patch updates Cycles, EEVEE and other viewport
engines. Exporters have not been updated yet. Some minimal (not master-ready)
changes to update the obj and alembic exporters can be found in P2336 and P2335.
Different file formats may want to handle these new instances in different ways.
For users, the only thing that changed is that the Point Instance node now
has a geometry mode.
This also fixes T88454.

This node takes a curve geometry input and creates a filled mesh at Z=0
using a constrained Delaunay triangulation algorithm. Because of the
choice of algorithm, the results should be higher quality than the
filling for 2D curve objects.
This commit adds an initial fairly simple version of the node, but more
features may be added in the future, like transferring attributes when
necessary, or an index attribute input to break up the calculations
into smaller chunks to improve performance.

This should be a no-change commit for now, but is required to enable
initial basic support of nodetrees in library override.
NOTE: Proper full support of liboverrides in nodes is yet to be designed
(has UX unresolved issues, since we likely do not want to expose/make
overridable ALL settings of ALL nodes).

This node sets the selected (or all) splines in curve to a chosen target
spline type. Poly, Bezier, and NURB splines can be converted to any of
the other types. This is meant to be a building block node, useful in
many procedural situations.
In the future the node could be optimized with multi-threading, or by
avoiding copying in many cases, either by retrieving the curve for write
access or by passing the raw vectors to the new splines where possible.

This node implements shortening each spline in the curve based on
either a length from the start of each spline, or a factor of the
total length of each spline, similar to the "Start & End Mapping"
panel of curve properties.
For Bezier curves, the first and last control points are adjusted
to maintain the shape of the curve, but NURB splines are currently
implicitly converted to poly splines.
The node is implemented to avoid copying where possible, so it outputs
a changed version of the input curve rather than a new one.

This adds id_properties_clear() and id_properties_ensure() functions
to RNA structs. This is meant as an initial change based on discussion
in review of D9697. However, they may be useful in other situations.
The change requires refactoring the internal idproperties callback to
return a pointer to the IDProperty pointer, which actually turns out
to be quite a nice cleanup.
An id_properties attribute could be added in the future potentially.

The menu lists all socket types that are valid for the node tree.
Changing a socket type updates all instances of the group and keeps
existing links to the socket.
If changing the socket type leads to incorrect node connections the
links are flagged as invalid (red) and ignored but not removed. This is
so users don't lose information and can then fix resulting issues.
For example: Changing a Color socket to a Shader socket can cause an
invalid Shader-to-Color connection.
Implementation details:
The new `NODE_OT_tree_socket_change_type` operator uses the generic
`rna_node_socket_type_itemf` function to list all eligible socket types.
It uses the tree type's `valid_socket_type` callback to test for valid
types. In addition it also checks the subtype, because multiple RNA
types are registered for the same base type. The `valid_socket_type`
callback has been modified slightly to accept full socket types instead
of just the base type enum, so that custom (python) socket types can be
used by this operator.
The `nodeModifySocketType` function is now called when group nodes
encounter a socket type mismatch, instead of replacing the socket
entirely. This ensures that links are kept to/from group nodes as well
as group input/output nodes. The `nodeModifySocketType` function now
also takes a full `bNodeSocketType` instead of just the base and subtype
enum (a shortcut `nodeModifySocketTypeStatic` exists for when only
static types are used).

- Line between two points
- Start Point, Direction, and Length

This patch adds a very simple node that explicitly converts a float to
an int. While this may seem redundant, it would offer 2 benefits to the
current requirement to use implicit float conversions:
1. It makes the node tree's intent more clear and self-documenting
(especially if changes in the future require integer inputs).
2. It eliminates undefined behavior in current/future nodes from float
inputs by guaranteeing that the input is an integer.
The node offers a variety of rounding techniques to make it more flexible.

This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.
Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.
As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.
There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
viewer nodes.
* Less visual clutter in node headers.

This node creates splines with more control points in between the
existing control points. The point is to give the splines more
definition for further tweaking like randomization with white noise,
instead of deforming a resampled poly spline with a noise texture.
For poly splines and NURBS, the node simply interpolates new values
between the existing control points. However, for Bezier splines,
the result follows the existing evaluated shape of the curve, changing
the handle positions and handle types to make that possible.
The number of "cuts" can be controlled by an integer input, or an
attribute can be used. Both spline and point domain attributes are
supported, so the number of cuts can vary using the value from the
point at the start of each segment.
Dynamic curve attributes are interpolated to the result with linear
interpolation.

This node implements the second option of T87429, creating points
along the input splines with the necessary evaluated information
for instancing: `tangent`, `normal`, and `rotation` attributes.
All generic curve point and spline attributes are copied to the
result points as well.
The "Count" and "Length" methods are just like the current options
in the resample node, but the output is points instead of a curve.
The "Evaluated" method uses the points you see on the curve directly,
and therefore should be the fastest.
The rotation data is retrieved from a transform matrix built with the
same method that the curve to mesh node uses. The radius attribute is
divided by 10 so the points don't look absurdly huge in the viewport.
In the future that could be an option.
For the implementation, one thing that could use an improvement
is the amount of temporary allocations while resampling to evaluated
points before the final points. I expect that reusing a buffer for
each thread would give a nice improvement.

Allows to define properties which will have proper units displayed
in the interface. The internal storage is expected to be seconds
(which matches how other times are stored in Blender).

The naming does not sound very exciting, but can't think of anything
better either.
For test it probably easiest to define FloatProperty with subdtype

This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame.
Two execution models:
- Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation.
- FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees. Operations are multi-threaded but do not run in parallel as Tiled (will be done in another patch).
This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage.
FullFrame breaking changes respect Tiled system, mainly:
- Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation.
- Any sampling is always done over inputs instead of last buffered operation.

While we could make this node work for boolean inputs in the future,
currently it's really just designed to compare "float-like" inputs.
Many comparison modes don't even make sense for boolean inputs.
Therefore, the simplest fix for this bug is just to disable the

The CoW copy of the node group was not updated correctly after it
changed. Arguably, tagging the node tree could also be part of
`ntreeUpdateTree` (which needs to be called after changes to the

depsgraph is tagged explicitly after `ntreeUpdateTree` is called,
so it should be fine here as well. This is similar to what is done

This node generates a naturally parametarized (even length edge) poly

"Count", and "Length". These are similar to the same options for the
line primitive node in end points mode.
I implemented this instead of a "Sample Points" node, because for this
operation it's trivial to keep the result as a curve, which is nice
since it increases flexibility, and because it can make instancing
simpler, i.e. using the transforms of each evaluated point rather than
requiring the construction of a "rotation" attribute.
