Audaspace: porting minor improvements from upstream

- NullDevice is now called None
- Automatic choice of best available device.
- Minor formatting, documentation and cmake fixes.

Fix issues with automatic proxy building

After merging patches and resolving conflicts, typo prevented correct operation.
This uncovered crash on NULL dereference as well.

Face Sets Topology: Initial working version

Face Sets Topology: Initial loop iteration implementation (one side only)

Geometry Nodes: Add initial version of mesh primitives

This commit includes nodes to build the following primitives:
- Cone
- Cylinder
- Circle
- Cube
- UV Sphere
- Ico Sphere
- Line
- Plane/Grid

In general the inputs are the same as the corresponding operators
in the 3D view.

**Line Primitive**
The line primitive has two modes-- adding vertices between two end
points, or adding vertices each at an offset from the start point.
For the former mode, there is a choice between a vertex count
and a distance between each point.

**Plane Primitive**
This commit includes the "Plane" and "Grid" primitives as one node.
Generally primitives are named after the simpler form of the shape they
create (i.e. "Cone" can make some more complex shapes). Also, generally
you want to tweak the number of subdivisions anyway, so defaulting to
plane is not an inconvenience. And generally having fewer redundant
base primitives is better.

**Future Improvements**
A following patch proposes to improve the speed of the cylinder, cone,
and sphere primitives: D10730. Additional possible future improvements
would be adding subdivisions to the cube node and rings to the cone
and cylinder nodes.

Face Sets Topology: Initial edge loop detection

WIP: Add instances data to spreadsheets

This commit does not currently compile, I'm pushing it so I can
continue work on another computer.

Merge remote-tracking branch 'origin' into compositor-anti-aliasing

Compositor Anti-Aliasing: addressed comments from code review

- Made node slightly larger to make text fit
- Renamed "Local Contrast Adaptation Factor" to "Contrast Limit"
- Removed unused enum
- Style: added brackets around if
- Style: Ran make format (excluded changes from unrelated files)

Face Sets Topology: Initial commit

Grease Pencil: Add LineArt modifier

This adds the LineArt grease pencil modifier.

It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.

This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.

These lines can then be baked and edited as regular grease pencil lines.
