Most of the code of brushes and tools has loops with a full indented

This adds a new brush property called "Deformation Target" which
controls how the brush deformations is going to affect the mesh data. By
default is set to Geometry, which makes the brushes displace the
vertices. When set to Cloth Simulation, the deformation of the brush is
applied to the cloth solver constraints, so the simulation is
responsible to apply the final deformation. This allows to add cloth
simulation effects to other sculpt tools with minor modifications to their
code.
This patch enables Cloth Simulation deformation target for Pose and
Boundary brushes, which are tools that are already designed to work in
low poly counts and produce large deformations. This allows creating the
most common cloth effects, like bending and compressing folds, without
relying on collisions.

The Pose FK mode assings the rotation origin to the boundary of the last
visited face set in the floodfill operation. In some cases, the topology
of the model may make the flood fill operation to visit a face set as the
first one (assinging it to target) and visit it again as the last one
(assinging it to origin). This will make the pose brush to default the
origin and target to the brush location and not to the face sets as it
considers that there is only one possible boundary.
This adds a GSet to ensure that a particular face set is not visited
twice in the flood fill, fixing these cases.

The scale deform mode includes rotation by default, so when when scaling
down a part of the models it becomes harder to control as the effect of
the rotation less predictable (similar to using trackball rotation in a
very small radius). This locks the rotation of the segment, so parts of
the model can be scaled down in a more predictable way.

This option allows posing meshes with different disconnected elements
using the Pose Brush.
This is achieved by doing the following:
- Creating an ID per vertex that stores the connected component of that vertex.
- By using those IDs, one fake topology connection is created per vertex to the nearest vertex in a different ID. The maximum distance to create that connection is determined by the "Max Element Distance" property. These fake connectivity neighbors are used in the Sculpt API functions iterators, so all the algorithms of the Pose Brush can run without modifications as if everything was part of the same mesh.
In order to make this work, the "Connected only" property of the Pose Brush needs to be disabled. This will add an extra performance cost to the Pose Brush and its preview. To achieve optimal results, max element distance should be as low as possible.

This implements squash and stretch as a deform mode for the Pose Brush.
It is similar to scale, but it applies different scale values in different
axis. To achieve this, the pivot local space of the transform needs to
be aligned to the segment when using this deform mode to apply the scale

When the brush size is bigger than the entire mesh, fdata.tot_co can be
0, so the pose origin will default to (0,0,0), which does not make much
sense. After this patch, the pose origin will be set to the farthest
vertex from the pose origin, which at least should be in the surface of
the mesh and in most cases in the direction the pose brush was already

This is an alternative deformation brush for the Pose Brush intended

using the segment's origin as a pivot. The inverted mode drags the

The only difference with the regular pose brush is that it is not
compatible with IK, so the option is disabled and set to 1 segment. The
rest of the options should work as expected.

This commit introduces a new mode for calculating the positions and
weights of the IK segments in the Pose Brush based on the Face Sets.
The first segment of the chain will always include all face sets inside
the brush radius and it will propagate until the boundary of the last
face sets added in the flood fill. Then consecutive connected face sets
are added to the chain until the chain length limit is reached or all
face sets of the mesh are already part of the chain.
This feature enables complete control over the pose brush origins in
case that is needed. Also, with this mode, the user can have a library
of base meshes with face sets already configured to get to the initial
pose as fast as possible.
