This commit adds support for drawing Dots strokes with a gradient factor to get artistic effects like watercolor.
Currently, the option is only supported by Dots materials, and in the future will be added to line strokes, but now there is a limitation on drawing engine and we will keep disabled on Line materials.
Also, added the option to align Dots and Boxes strokes textures aligned with the drawing path to get more fluid strokes.
Using GP_BRUSH_MATERIAL_PINNED to switch between active material and brush material, instead of updating all brushes on active material changes. This will allow brushes to have no material and therefore to not inflate the user count.
This fix T62465.

This commit groups several options that were tested in grease pencil branch:
- Changes to fill algorithms and improves, specially in small areas and stroke corners.
New options has been added in order to define how the fill is working and internally there are optimizations in detect the small areas in the extremes.
Kudos to @charlie for coding this fill improvements.
- New 3D cursor view plane option.
Now it's possible to lock the drawing plane to the 3D cursor and use the 3D cursor orientation. This allows more flexibility when you are drawing and reduce the need to create geometry to draw over surfaces.
- Canvas Grid now can be locked to 3D cursor.
- New option to reproject stroke using 3D cursor.
- Small tweaks and fixes.
Changes reviewed by @pepeland and @mendio
Use the term "AFTER" instead of "OFS" since it wasn't obvious these
macros operate on everything after the struct member passed.
Avoid casting to non-const types when only reading.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
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This is often invalid, outdated or misleading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
- Replace BKE_brush_getactive_gpencil -> BKE_paint_brush
(no need for per-paint-type brush access).
- Rename TOT_GP_EDITBRUSH_TYPES -> GP_EDITBRUSH_TYPE_MAX
(avoid sharing prefix w/ unrelated constants).
- Rename instances of `GP_EditBrush_Data` to 'gp_brush'
(`Brush` is typically called 'brush').
Each mode had its own logic for initializing paint structs,
move to a single function.
Also remove "BKE_brush_get_gpencil_paint", entering grease pencil
mode is responsible for ensuring the data is created.
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.
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
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

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 reverts change to BKE_brush_add,
callers now remove the extra user.
Note this isn't very convenient for callers but
is consistent with other ID types.
In the future we will probably remove this and have new
ID's created with zero users.
