128eb6cbe9 Modifiers: export motion blur velocity through attribute
Previously fluid simulation and Alembic modifiers had a dedicated function
to query the velocity for motion blur. Now use a more generic system where
those modifiers output a velocity attribute.

Advantages:
* Geometry and particle nodes can output velocity through the same mechanism,
  or read the attribute coming from earlier modifiers.
* The velocity can be preserved through modifiers like subdivision surface or
  auto smooth.
* USD and Alembic previously only output velocity from fluid simulation, now
  they work with velocity from other sources too.
* Simplifies the code for renderers like Cycles and exporters like
  Alembic and USD.

This breaks compatibility:
* External renderers and exporters accessing these velocities through the
  Python API now need to use the attribute instead.
* Existing modifier node setups that create an attribute named "velocity"
  will render differently with motion blur.

c8f80453d5 Modifier: add support for vertex groups
Allow blending the imported cache with the modifiers stack above the
MeshCache modifier.

This is particularly useful for instance when dealing with cloth
simulations performed in another software, where some parts of the cloth
are completely pinned (non-simulated, following the armature). Indeed,
this would allow modifying the animation in some areas without having to
rebake the other parts or the cloth, resulting in a much more flexible
workflow.

20ef771374 Modifier: smooth interpolation support
Add an option to the mask modifier to use the vertex weights to generate
smooth in between geometry, instead of just deleting non complete faces.

This can be used to make all sorts of smooth dissolve animations
directly with geometry, which are usually hacked together with shaders.
It also allows for implicit function plotting using geometry nodes and
boolean like operations on non manifold geometry with the proximity
modifier.

1ab6d5c1dc Surface Deform: support sparse binding mode for improving performance.
When a vertex group is used to limit the influence of the modifier
to a subset of vertices, binding data for vertices with zero weight
is not needed. This wastes memory, disk space and CPU cycles.

If the vertex group contents is known to be final and constant,
it is reasonable to optimize by only storing data group vertices.
This has to be an option in case the group can change.

Supporting this requires adding a vertex index field and spliting
the vertex count into mesh and bind variants, but both happen to
fit in available padding. The old numverts field is renamed to the
new bound vertex count field to maintain the array length invariant.
Versioning is used to initialize the other new fields.

If a file with sparse binding is opened in an old blender version,
it is corrupted into a non-sparse bind with vertex count mismatch,
preventing the modifier from working until rebind.

3b6ee8cee7 Refactor: Move vertex group names to object data
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.

As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.

The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.

This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.

Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

9009ac2c3d Geometry Nodes: new Viewer node
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.

6471cf6bc8 UI: Clean up labels and descriptions: "Draw" to "Display"
In Blender, we used to use the term 'draw' to refer to information
displayed to the user. For version 2.80, it was decided to change these
instances to 'display' instead. This was to avoid the ambiguity between
end-user drawing tools and display options.

From the Oxford English Dictionary:
 - Draw: produce (a picture or diagram) by making lines and marks on
   paper with a pencil, pen, etc.
 - Display: show (data or an image) on a computer, television, or
   other screen.

Therefore, we should use draw when referring to drawing tools for
making marks, but use display when referring to information
shown/displayed to the user. From a user POV, the computer displays
certain information, whereas the user draws a mark.

Apparently this change was not implemented consistently, so this patch
changes all remaining relevant instances of "draw".

aa030d3459 Fix: Unable to animate nodes modifier exposed properties
The RNA path used for animating the settings passed to the node tree
is incorrect. Currently it's just `settings.property_name`, but it's
the path from the ID, not the modifier, so it should be
`modifiers[modifier_name].settings.property_name`.

However, the "Settings" struct is separated in RNA and DNA, which means
that the callback to get the RNA path does not know about the modifier's
name in order to fill the above path, so some reference to the modifier
in the "Settings" struct would be necessary, which would create a
convoluted layout in the `ModifierData` struct.

Instead, this commit simply removes the "Settings" struct from RNA,
which isn't as elegant from the point of view of the Python API,
but otherwise it's a nice simplification. Note that we don't remove the
"Settings" struct from DNA, because it would break reading old files.

for the triangulate modifier and in exporters.

Note the modifier was introduced with "Ngon Method" in rBa7b44c82e5b9 but
was renamed to "Polygon Method" in rBf4762eb12ba5.

Since quads are also polygons (and quads have their own method), the
term "N-gon" is more appropriate here and is also described in the

Docs have been updated in rBM7539 (partially - the method would also

With the recent performance improvement, the Connected Mode is in some
cases only double the speed than the usual merge all strategy but in
other cases it may be even faster. The bottleneck is somewhere further
down the line of merging geometry.

The motivation for this patch came from T80897, because the merging in
complex solidify is making it very slow.
Now merging can be removed from solidify without greater consequences,
as this is just a quicker and more advanced algorithm to do the same

600fb28b62 Geometry Nodes: active modifier + geometry nodes editor
This commit adds functions to set and get the object's active
modifier, which is stored as a flag in the ModifierData struct,
similar to constraints. This will be used to set the context in
the node editor. There are no visible changes in this commit.

Similar to how the node editor context works for materials, this commit
makes the node group displayed in the node editor depend on the active
object and its active modifier. To keep the node group from changing,
just pin the node group in the header.

* Shortcuts performed while there is an active modifier will affect
  only that modifier (the exception is the A to expand the modifiers).
* Clicking anywhere on the empty space in a modifier's panel will make it active.

These changes require some refactoring of object modifier code. First
is splitting up the modifier property invoke callback, which now needs
to be able to get the active modifier separately from the hovered
modifier for the different operators.

Second is a change to removing modifiers, where there is now a separate
function to remove a modifier from an object's list, in order to handle
changing the active.

Finally, the panel handler needs a small tweak so that this "click in panel"
event can be handled afterwards.

Notes on the Generic attribute access API

The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
  This is mainly necessary, because we have to deal with "legacy" attributes
  such as vertex weights and attributes that are embedded into other structs
  such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
  attribute is stored on. So we want to abstract away the interpolation that
  that adapts attributes from one domain to another domain (this is not
  actually implemented yet).

Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
  access and one for write access might be enough, because we know all the ways
  in which attributes are stored internally. We don't want more different internal
  structures in the future. On the contrary, ideally we can consolidate the different
  storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.
