This implements Snake Hook as a deform type for the cloth brush. This
brush changes the strength of the deformation constraints per brush step
to avoid affecting the results of the simulation as much as possible. It

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

This brush includes a set of deformation modes designed to deform and
control the shape of the mesh boundaries, which are really hard to do
with regular sculpt brushes (and even in edit mode). This is useful
for creating cloth assets and hard surface base meshes.
The brush detects the mesh boundary closest to the active vertex and
propagates the deformation using the brush falloff into the mesh.
It includes bend, expand, inflate, grab and twist deform modes.
The main use cases of this brush are the Bend and Expand deformation
modes, which depend on a grid topology to create the best results.
In order to do further adjustments and tweaks to the result of these
deformation modes, the brush also includes the Inflate, Grab and
Twist deformation modes, which do not depend that much on the topology.
Grab and Inflate are the same operation that is implemented in the
Grab and Inflate tools, they are also available in the boundary brush
as producing deformations with regular brushes in these areas is very
hard to control.
Even if this brush can produce deformations in triangle meshes and
meshes with a non-regular quad grid, the more regular and clean the
topology is, the better. Most of the assets this brush is intended to
deform are always created from a cylindrical or plane quad grid, so it
should be fine. Also, its algorithms can be improved in future versions
to handle more corner cases and topology patterns.

This makes possible to choose between a local and a global simulation

When global simulation is enabled, the cloth brush simulates the entire
mesh without taking any simulation limits into account.
This was possible before by setting the simulation limits to 10 (the
current maximum value allowed) so the entire mesh was inside the limits,
but this was a hack as the limits scale with the radius and there should
not be any limitation on how big the simulated area can be to be able to
simulate an entire object. This also allows to make a more clear

The cloth brush has a defined simulated area with a falloff. In the falloff
area (the area between the dashed white circle and the exterior white
circle), simulation properties change in order to fade out the
simulation deformation effects towards the boundary.
With some brushes and stroke types (like anchored strokes with pinching
or grabbing with full strength), it is possible to apply more force than
what the boundary falloff can compensate, so the simulation breaks when
this happens.
This option pins the falloff area with softbody constraints, This
produces a much better deformation falloff and it is no longer possible
to move the vertices near the simulation boundary, so the simulation
won't break no matter the strength of the forces applied inside the
simulated areas.
This is an option as it is particularly useful for some brushes to add
localized details, but for brushes that are supposed to deform the
entire mesh (like the grab brush in D8424), this can add unwanted
softbody constraints that affect the simulation result.

This option allows posing meshes with different disconnected elements

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.

- The boundary vertex detection in meshes is not ideal and it fails with triangulated geometry, but it is the same as in the smooth brush. After fixing this, we should refactor the smooth brush to use the API and let the automasking option manually control the affected vertices.

Avoids mixing these in with regular variables in code-completion.
Use char for pad members except for 'void *', to make size clearer.
Removed/shrink a few redundant padding vars which were >= 8 bytes.
New edit mode operator and post-processing brush option.
Trim works on a single GP stroke. It removes trailing points before and after the first intersection (or loop) nearest to the start of the stroke.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This helps to generate cleaner topology and define sharp features for dynamic
topology. Best used on relatively low-poly meshes, it is not needed as much
for high detail areas and has a performance impact.
Differential Revision: https://developer.blender.org/D4189
- Vertex & weight paint now use the 'blend' setting.
- Weight paint now has it's own tool setting,
since weight paint doesn't deal with color - we'll likely
support different tools eventually.
The toolbar now shows brush types, the brush selector now
only shows brushes matching the current tool type.
Details:
- Add's Paint.tool_slots (used by the toolbar).
- Removed custom grease pencil brush tool code.
- Bumped subversion.
See T57526 for details.
Now it's possible to disable the lasso effect of the fill color while drawing with a fill color.
This sometimes is required to see the lines and it's the first step to implement a new lasso brush.
After some artist feedback the material selection was not clear.
Now, the material can be selected in the top bar or in the properties panel.
1) If the material is selected in properties panel, all Brushes except pinned will be assigned to this material.
2) If the material is selected in the brush, the properties panel is updated to set the active material.
Added a new Pin icon to keep locked the material to one brush

- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
This makes brush influence into a tube instead of a sphere.
It can be used along the outline of a mesh to adjust it's silhouette.
Note that all this takes advantage of changes from vertex paint,
from testing this seems useful so exposing from the brush options.
GSOC 2017 by Darshan Kadu, see: D2859.
This is a partial merge of some of the features from
the soc-2017-vertex_paint branch.
- Alpha painting & drawing.
- 10 new color blending modes.
- Support for vertex select in vertex paint mode.
