The commit rB6f63417b500d that made exact boolean work on meshes
with holes (like Suzanne) unfortunately dramatically slowed things
down on other non-manifold meshes that don't have holes and didn't
need the per-triangle insideness test.
This adds a hole_tolerant parameter, false by default, that the user
can enable to get good results on non-manifold meshes with holes.
Using false for this parameter speeds up the time from 90 seconds
to 10 seconds on an example with 1.2M triangles.
This fixes two issues that were preveting normal orientation for working:
- The translation of component of the object matrix should not be
considered when converting a normal to world space.
- Whe using cursor for depth, the depth for the shape should be taken
directly from the cursor (which is already unprojected and updated)
instead of from the brush, which may have not been updated.

The boolean solver crashes when there is no geometry in the mesh. Also,
using the trimming tools without a valid intersection in the PBVH will
make the orientation and position functionality of the trimming shape
not work, so this is the safer solution.

Issue exposed by rB4c7b1766a7f1.
Main idea is that non-memfile first undo step should check into previous
memfile and tag the ID it is editing as `future_changed`.
That way, when we go back and undo to the memfile, said IDs are properly
detected as changed and re-read from the memfile.
Otherwise, undo system sees them as unchanged, and just re-use the
current data instead.
Note that currently only Sculpt mode seems affected (probably because it
is storing the mode switch itself as a Sculpt undo step instead of a
memfile one), but similar action might be needed in some other cases
too.

The code was trying to ignore hidden geometry when doing boolean,
which is correct when used as a tool, but not when a modifier.
Added a "keep_hidden" argument to bmesh_boolean to distinguish the
two cases.
Also fixed a bug when the tool is used with hidden geometry that
is attached to unhidden geometry that is deleted by the operation.

This adds a tool property for sculpt line gesture tools (line and

using the infinite line to bisect the mesh in two parts.
To achieve that, the line gesture now has two extra side planes that can

This adds the ability to change the active side when the line gesture is

This adds an operator property to use the paint cursor radius and
position for the depth of the trimming shape created by the trimming

When enabled, the shape is located in the surface point when the gesture
started and it will have the depth of the cursor radius. When the cursor
is not over the mesh, the shape will be positioned at the center of the
depth of the whole object from the viewport camera.

The code to handle object transforms was wrong. Now the trimming mesh
and depts is calculated in world space, using the real view origin and
normal and then stored in object space in the mesh and in the original
coordinates array. As now both meshes for the boolean operation are in
the same object space, the space conversion code can also be removed
from the boolean function.

This enables a union boolean mode for the trimming gestures tools which
adds geometry to the mesh instead of cutting it.
It also adds a Join mode, which adds the geometry directly without
using a boolean operation.
Depending if you plan to use dyntopo or not, it is useful to have both
options available.
This is using the full depth of the object from the camera view for the
depth of the geometry, but options for controlling the trimming depth in
all modes are going to be added in later patches

This tool projects all vertices to the right of the plane defined by the

Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time.
This commit includes:
- SCULPT_UNDO_COLOR for undo support in sculpt mode
- SCULPT_UPDATE_COLOR and PBVH flags and rendering
- Sculpt Color API functions
- Sculpt capability for sculpt tools (only enabled in the Paint Brush for now)
- Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint)
- Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint)
- Remesher reprojection in the Voxel Remehser
- Paint Brush and Smear Brush with color smoothing in alt-smooth mode
- Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors
- Color Filter
- Color picker (uses S shortcut, replaces smooth)
- Color selector in the top bar
