8df968d69f "Show Texture in texture tab" button: full support for Sculpt / Paint
In {rBb279fef85d1a} the button that displays a texture in a Properties
Editor texture tab was added for geometry nodes.
Same commit will actually show them for Brush textures as well (but
disabled -- because the Texture users dont match).
This task is for finanlizing proper support for Brush textures as well.
There was originally a separate patch for this (see {D9813}) but most of
it was already implemented by above commit.

**what this solves**
from the default startup file:
- go to any sculpt or paint mode and add a texture to your brush
- observe the button to edit this texture in the Properties editor is
greyed out

{F9860470}

There are two possible solutions:
- [1] call the texture template for the brush `texture_slot` texture
(instead of the brush 'texture') from the python UI code, this is then
working in harmony how ButsTextureUser works for brushes
- [2] tweak the way `ButsTextureUser` works (dont rely on
`RNA_BrushTextureSlot` there)

This patch implements the first solution.
Since `brush.texture_slot` is `br->mtex` RNA wrapped and `brush.texture`
is `br->mtex.tex` RNA wrapped, this really comes down to doing the same
thing. I checked that creating a new texture and unlinking/deleting will
have the same results even though they take slightly different code
paths: assignment and NULLing the pointers are working on the same (see
above) and RNA update callbacks also do the same [even though in
different functions]:
- brush.texture will do rna_Brush_main_tex_update
- brush.texture_slot.texture will do rna_TextureSlotTexture_update /
rna_TextureSlot_update
(only difference here is an additional DEG relations update in the case
of texture_slot which should not do harm)

1352d81b17 GPencil: Fill tool refactor and Multiframe in Draw mode
This commit is a refactor of the fill tool to solve several problems we had since the first version of the tool.

Changes:

* The filling speed has been improved for each step of the process with the optimization of each algorithm/function.
* New `AutoFit` option to fill areas outside of the viewport. When enable, the total size of the frame is calculated to fit the filling area.
* New support multiframe filling. Now it is possible to fill multiple similar frames in one go.
* New `Stroke Extension` option to create temporary closing strokes. These strokes can be displayed and adjusted dynamically using wheel mouse or PageUp/Down keys.
* Parameter `Resolution` now is named `Precision` and has been moved to topbar.
* `Resolution` now has decimals and can be lower than 1 to allow quick filling in storyboarding workflows. Maximum value has been set as 5.
* Parameter `Simplify` has been moved to Advanced panel.
* Improved fill outline detection. In some cases, the outline penetrated the area to be filled with unexpected results.
* Fixes some corner case bugs with infinite loops.

As a result of this refactor, also these new functionalities has been added.

* New support for multiframe in `Draw` mode. Any drawing in active frame is duplicated to all selected frame.
* New multiframe display mode. Keyframes before or after of the active frame are displayed using onion colors. This can be disable using Onion overlay options.

d23894d3ef Sculpt: Multires Displacement Smear
This tool implements smearing for multires displacement over the limit
surface, similar to how smearing for colors and topology slide works.
When used the displacement values of the vertices "slide" over the
topology, creating the effect of smearing the surface detail.

As the brush just modifies displacement values instead of coordinates,
the total displacement of the affected area doesn't change. This means
that this smearing effect can be used multiple times over the same area
without generating any artifacts in the topology.

When the brush is used with the pinch or expand smear modes,
displacement differences are pushed into the same area, creating hard
surface effects without pinching the topology.

As any other brush that relies on the limit surface (like displacement
erasers), this will work better after using apply base.

cc6ec71b19 Sculpt: Wet paint area radius
This adds a new property to the sculpt vertex color paint brush to limit
the area of the brush that is going to be used to sample the wet paint
color. This is exactly the same concept as normal radius and area radius
that exist for sculpting brushes for sampling the surface depth and
orientation.

When working near color hard edges, this allows to prevent the color
from the other side of the edge to blend into the wet paint.

With 1.0 (the previous default) wet paint radius, as soon as the brush touches
one vertex of the other color, the wet paint mix color changes, making it
impossible to maintain the border between the two colors.

0d5ec990a9 Sculpt: Experimental Pen Tilt Support

by tweaking the tilt strength property, which controls how much the pen
angle affects the sculpt normal. This is available in Draw, Draw Sharp,
Flatten, Fill, Scrape and Clay Strips brushes, but it can be enabled in

The purpose of this patch is to have a usable implementation of pen tilt

platforms this feature is supported and how well it works. If it works
ok, more tools and features that rely on pen tilt can be implemented,

8ef353fa50 Sculpt: Cloth Simulation Dynamic area mode
This simulation area mode moves the active area with the brush. When
enabled, the cloth brush has no restrictions on stroke length, area or
mesh vertex count.

In order to work, this enables PBVH nodes dynamically for simulation as
the stroke location moves and builds the constraints for new nodes
during the stroke. When a node is not inside the simulated area, all the
constraints that were created for it and vertex collisions are not
computed. The simulation limits falloff areas and constraints tweaking
control how the simulated and no simulated nodes blend.

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

9ab3b8f7f4 UI: Remove cutoff text in popovers for 2.90 release
Many of these popovers could use a design pass in 2.91, but for 2.90 we
don't want to change any UI strings at this point, so the best way to
solve the cutoff text is to widen the popovers. Sadly this won't affect
popovers when other languages besides English have longer strings, but
solving that is a much larger task.

Another benefit is that tweaking sculpt / paint brush options feels much
less cramped with slightly wider popovers.

I only know of one string that is still slightly cutoff by default with
this patch, the "Max Element Distance" property of the pose brush in the
sculpt mode brush settings popover. But I didn't think it was worth
widening that popover more to deal with that one case.

ed9c0464ba Sculpt: Boundary Brush
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
distinction between cloth brush presets that are intended to be used in
local areas to add details or globally to generate the base shape of the

bf65820782 Sculpt: Cloth brush Pin Simulation Boundary property
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.

438bd82371 Sculpt: Pose Brush option to affect loose parts
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.
