Add new cavity automasking mode based on local mesh
curvature. Cavity masking is a great way to quickly add
detail in crevices and the like. It's meant to be used
with the Paint brush in color attribute mode. It does
work with other brushes but the results can be unpredictable.
{F13131497}
The old "dirty mask" operator has been replace with a new
"mask from cavity" operator that shares the same code with
cavity automasking.
Differences from the sculpt-dev implementation:
* It uses the word "cavity." When I first implemented
this I wasn't aware
this feature existed in other software (and other
paint modes in Blender),
and for reasons that escape me today I initially
decided to call it a concave or
concavity mask.
* The cavity factor works a bit differently. It's
no longer non-linear and functions as a simple
scale around 0.5f.
* Supports custom curves.
* Supports blurring.

Rewrite PBVH draw to allocate attributes into individual VBOs.
The old system tried to create a single VBO that could feed
every open viewport. This required uploading every color and
UV attribute to the viewport whether needed or not, often exceeding
the VBO limit.
This new system creates one VBO per attribute. Each attribute layout is
given its own GPU batch which is cached inside the owning PBVH node.
Notes:
* This is a full C++ rewrite. The old code is still there; ripping it out
can happen later.
* PBVH nodes now have a collection of batches, PBVHBatches, that keeps
track of all the batches inside the node.
* Batches are built exclusively from a list of attributes.
* Each attribute has its own VBO.
* Overlays, workbench and EEVEE can all have different attribute
layouts, each of which will get its own batch.

This patch contains an initial set of nodes to access basic
mesh topology information, as explored in T100020.
The nodes allow six direct topology mappings for meshes:
- **Corner -> Face** The face a corner is in, the index in the face
- **Vertex -> Edge** Choose an edge attached to the vertex
- **Vertex -> Corner** Choose a corner attached to the vertex
- **Corner -> Edge** The next and previous edge at each face corner
- **Corner -> Vertex** The vertex associated with a corner
- **Corner -> Corner** Offset a corner index within a face
And two new topology mappings for curves:
- **Curve -> Points** Choose a point within a curve
- **Point -> Curve** The curve a point is in, the index in the curve
The idea is that some of the 16 possible mesh mappings are more
important, and that this is a useful set of nodes to start exploring
this area. For mappings with an arbitrary number of connections, we
must sort them and use an index to choose a single element, because
geometry nodes does not support list fields. Note that the sort
index has repeating behavior as it goes over the "Total" number of
connections, and negative sort indices choose from the end.
Currently which of the "start" elements is used is determined by the
field context, so the "Field at Index" and "Interpolate Domain" nodes
will be quite important. Also, currently the "Sort Index" inputs are
clamped to the number of connections.
One important feature that isn't implemented here is using the winding
order for the output elements. This can be a separate mode for some
of these nodes. It will be optional because of the performance impact.
There are several todos for separate commits after this:
- Rename "Control Point Neighbors" to be consistent with this naming
- Version away the "Vertex Neighbors" node which is fully redundant now
- Implement a special case for when no weights are used for performance
- De-duplicating some of the sorting logic between the nodes
- Improve performance and memory use of topology mappings
- Look into caching some of the mappings on meshes

Because they are friendlier to use in C++ code than the existing mesh
mapping API, these mappings from one domain to another were often
reimplemented in separate files. This commit moves some basic
implementations to a `mesh_topology` namespace in the existing
mesh mapping header file. These is plenty of room for performance
improvement here, particularly by not using an array of Vectors, but
that can come later.

When the visual aids are disabled, but the extend factor
is > 0, the lines must be extended, but not displayed.
Also, some variables renamed to clarify.
This adds support for showing geometry passed to the Viewer in the 3d
viewport (instead of just in the spreadsheet). The "viewer geometry"
bypasses the group output. So it is not necessary to change the final
output of the node group to be able to see the intermediate geometry.
**Activation and deactivation of a viewer node**
* A viewer node is activated by clicking on it.
* Ctrl+shift+click on any node/socket connects it to the viewer and
makes it active.
* Ctrl+shift+click in empty space deactivates the active viewer.
* When the active viewer is not visible anymore (e.g. another object
is selected, or the current node group is exit), it is deactivated.
* Clicking on the icon in the header of the Viewer node toggles whether
its active or not.
**Pinning**
* The spreadsheet still allows pinning the active viewer as before.
When pinned, the spreadsheet still references the viewer node even
when it becomes inactive.
* The viewport does not support pinning at the moment. It always shows
the active viewer.
**Attribute**
* When a field is linked to the second input of the viewer node it is
displayed as an overlay in the viewport.
* When possible the correct domain for the attribute is determined
automatically. This does not work in all cases. It falls back to the
face corner domain on meshes and the point domain on curves. When
necessary, the domain can be picked manually.
* The spreadsheet now only shows the "Viewer" column for the domain
that is selected in the Viewer node.
* Instance attributes are visualized as a constant color per instance.
**Viewport Options**
* The attribute overlay opacity can be controlled with the "Viewer Node"
setting in the overlays popover.
* A viewport can be configured not to show intermediate viewer-geometry
by disabling the "Viewer Node" option in the "View" menu.
**Implementation Details**
* The "spreadsheet context path" was generalized to a "viewer path" that
is used in more places now.
* The viewer node itself determines the attribute domain, evaluates the
field and stores the result in a `.viewer` attribute.
* A new "viewer attribute' overlay displays the data from the `.viewer`
attribute.
* The ground truth for the active viewer node is stored in the workspace
now. Node editors, spreadsheets and viewports retrieve the active
viewer from there unless they are pinned.
* The depsgraph object iterator has a new "viewer path" setting. When set,
the viewed geometry of the corresponding object is part of the iterator
instead of the final evaluated geometry.
* To support the instance attribute overlay `DupliObject` was extended
to contain the information necessary for drawing the overlay.
* The ctrl+shift+click operator has been refactored so that it can make
existing links to viewers active again.
* The auto-domain-detection in the Viewer node works by checking the
"preferred domain" for every field input. If there is not exactly one
preferred domain, the fallback is used.
Known limitations:
* Loose edges of meshes don't have the attribute overlay. This could be
added separately if necessary.
* Some attributes are hard to visualize as a color directly. For example,
the values might have to be normalized or some should be drawn as arrays.
For now, we encourage users to build node groups that generate appropriate
viewer-geometry. We might include some of that functionality in future versions.
Support for displaying attribute values as text in the viewport is planned as well.
* There seems to be an issue with the attribute overlay for pointclouds on
nvidia gpus, to be investigated.

This commit is an improvement in the previous fill tool
changes in order to improve how the extended strokes
are managed.
* Now, the algorithm checks if the extend cross a standard stroke, not only extend strokes.
* Option to enable or disable the stroke cross checking
because this can be slow in very complex scenes.
* Added `D` key to toggle stroke cross option.
* Option to use only collide strokes to be used as fill limit.
If the option to use only collide strokes is enabled, the
open extensions are in different color.
* Status text now shows mode and the actual extend factor.
This commits also contains a refactor of the loops
to use arrays as much as possible.

Mathutils types were always GC tracked even when it wasn't intended.
Not having to track objects speeds up Python execution.
In an isolated benchmark created to stress test the GC
creating 4-million vectors (re-assigning them 100 times), this gives
an overall ~2.5x speedup, see: P3221.
Details:
Since [0] (which added support for sub-classed mathutils types)
tp_alloc was called which defaults to PyType_GenericAlloc which always
GC tracked the resulting object when Py_TPFLAGS_HAVE_GC was set.
Avoid using PyType_GenericAlloc unless the type is sub-classed,
in that case the object is un-tracked.
Add asserts that the tracked state is as expected before tracking &
un-tracking, to ensure changes to object creation don't cause objects
to be tracked unintentionally.
Also assign the PyTypeObject.tp_is_gc callback so types optionally GC
track objects only do so when an object is referenced.

This patch adds 5th mode to Time offset modifier, which should allow
to create time segments list.
This will allow users to chain together multiple time ranges in 4 modes:
- Forward
- Backwards
- Pingpong
- Reverse Pingpong
It also comes with additional Repeat parameter which specifies number
of times particular segment should run.
The mechanic of it is transforming initial parameters into array of frames which
are mapped to existing cfra (current frame) value.
