This operator lets the user control the voxel/detail size of the voxel remesher directly from the 3D view in a similar way the Brush radius and strength are controlled. The shorcut from sculpt mode is Shift + R (similar to Shift + F for brush strength).
It shows a grid that represents the real voxel size of the object. The grid and the text are automatically aligned to the view to avoid rendering all voxels with thousands of lines.
It also has a slow mode when pressing shift that works like the slow mode of the brush radius control.
This operator controls the value changes sensitivity automatically to avoid jumping to extremelly high resolutions and run out of memory.
This way, adjusments done in lower voxel sizes are more precise. Pressing Ctrl disables this functionality and allows changing the voxel size directly in a linear way.

The issue was that we were creating temporary mesh copies and storing
them in bmain and then later using BKE_mesh_nomain_to_mesh which would
add them to bmain once more (duplicates).
This would lead to crashes later as the custom data of the mesh could be
trashed quite easily.
Face Sets are the new system to control the visibility state of the mesh in sculpt and paint modes. They are designed to work in modes where brushes are the primary way of interaction and they provide much more control when working with meshes with complex shapes and overlapping surfaces.
This initial commit includes:
- Sculpt Face Sets data structures and PBVH rendering.
- Face Set overlay and opacity controls.
- Sculpt Undo support.
- Remesher reprojection support. The visibility state of the mesh is also preserved when remeshing.
- Automasking and Mesh filter support.
- Mask expand operator mode to expand Face Sets (Shift + W) and flood fill areas by connectivity (press Ctrl while expanding).
- Sculpt Mode Face Sets and Visibility API.
- Sculpt Face Sets creation and visibility management operators.
- Operator to randomize the Face Sets colors.
- Draw Face Sets brush tool to create and edit the Face Sets. Drawing on the mesh creates a new Face Set. Pressing Ctrl before drawing modifies the Face Set under the brush at the beginning of the stroke.
- Updated keymap and menu to work with Face Sets from Sculpt Mode (H to toggle visibility, Alt + H to show all, Shit + H to hide).
- Pie menu on the W key with Face common Sets operations.
Know limitations:
- Multires support. The Face Sets and Visibility API needs to be implemented for Multires.

This should fix most of the shrinkwrap artifacts when the preserve volume option is active. After this commit the default voxel remehser settings should not fail in the default cube.

Quadriflow does not support non manifold meshes. (Edges with > 3
connected faces and discontinuous face normal directions)
While it does sometimes "work" in these configurations, the results are
not good and in most cases it just flat out will crash.
Added a sanity check to make sure that the input mesh is manifold.

This commit enables OpenVDB adaptivity in the voxel remesher. It can be useful to reduce the polygon count if you want to switch to dyntopo after using the voxel remesher workflow.

This patch adds paint symmetry support to Quadriflow. It bisects and mirrors the input and the output from the remesher to build the final mesh using the preserve boundary option.
This is also an important performance improvement in Quadriflow because it only needs to process half of the mesh with half the resolution.

This commit fixes most of the issues we currently have in the voxel remesher. Mesh volume is preserved when doing multiple iterations, so the sculpt won't shrink and smooth each time you run the remesher. Mesh topology is much better, fixing most issues related to mask extraction and other topology based operations.

The active object can be `NULL`, which causes a segfault in
`BKE_object_is_in_editmode(NULL)` (and if that were made NULL-safe, the
segfault would happen further down in `object_remesh_poll()`).
These functions deal with voxel remeshing of Mesh data,
and aren't related to MOD_remesh.c for e.g.
Name so other kinds of remeshing wont cause confusion.
The voxel remesher introduces a new workflow for sculpting without any of the limitations of Dyntopo (no geometry errors or performance penalty when blocking shapes). It is also useful for simulations and 3D printing.
This commit includes:
- Voxel remesh operator, voxel size mesh property and general remesh flags.
- Paint mask reprojection.
- Geometry undo/redo for sculpt mode. This should support remesh operations as well as future tools that modify the topology of the sculpt in a single step, like trimming tools or mesh insert brushes.
- UI changes in the sculpt topbar and the mesh properties pannel.
