This patch contains an initial pixel extractor for PBVH and an initial paint brush implementation.
PBVH is an accelleration structure blender uses internally to speed up 3d painting operations.
At this moment it is extensively used by sculpt, vertex painting and weight painting.
For the 3d texturing brush we will be using the PBVH for texture painting.
Currently PBVH is organized to work on geometry (vertices, polygons and triangles).
For texture painting this should be extended it to use pixels.

# Scope
This patch only contains an extending uv seams to fix uv seams. This is not actually we want, but was easy to add
to make the brush usable.
Pixels are places in the PBVH_Leaf nodes. We want to introduce a special node for pixels, but that will be done
in a separate patch to keep the code review small. This reduces the painting performance when using
low and medium poly assets.
In workbench textures aren't forced to be shown. For now use Material/Rendered view.
# Rasterization process
The rasterization process will generate the pixel information for a leaf node. In the future those
leaf nodes will be split up into multiple leaf nodes to increase the performance when there
isn't enough geometry. For this patch this was left out of scope.
In order to do so every polygon should be uniquely assigned to a leaf node.
For each leaf node
for each polygon
If polygon not assigned
assign polygon to node.
Polygons are to complicated to be used directly we have to split the polygons into triangles.
For each leaf node
for each polygon
extract triangles from polygon.
The list of triangles can be stored inside the leaf node. The list of polygons aren't needed anymore.
Each triangle has:
poly_index.
vert_indices
delta barycentric coordinate between x steps.
Each triangle is rasterized in rows. Sequential pixels (in uv space) are stored in a single structure.
image position
barycentric coordinate of the first pixel
number of pixels
triangle index inside the leaf node.
During the performed experiments we used a fairly simple rasterization process by
finding the UV bounds of an triangle and calculate the barycentric coordinates per
pixel inside the bounds. Even for complex models and huge images this process is
normally finished within 0.5 second. It could be that we want to change this algorithm
to reduce hickups when nodes are initialized during a stroke.

Currently, hovering over a socket itself shows no tooltip at all, while
hovering over its value field shows "Default value", which is not helpful.
This patch therefore implements socket tooltips following the proposal at
https://blender.community/c/rightclickselect/2Qgbbc/.
A lot of the basic functionality was already implemented for Geometry Nodes,
where hovering over the socket itself shows introspection info.
This patch extends this by:
- Supporting dynamic tooltips on labels, which is important for good tooltip
coverage in a socket's region of the node.
- Adding a function to setting a dynamic tooltip for an entire uiLayout, which
avoids needing to set it manually for a wide variety of socket types.
- Hiding the property label field in a tooltip when dynamic tooltip is also
provided. If really needed, this label can be restored through the dynamic
tooltip, but in all current cases the label is actually pointless anyways
since the dynamic tooltip gives more accurate and specific information.
- Adding dynamic tooltips to a socket's UI layout row if it has a description
configured, both in the Node Editor as well as in the Material Properties.
Note that the patch does not add any actual tooltip content yet, just the
infrastructure to show them. By default, sockets without a description still
show the old "Default value" tooltip.
For an example of how to add socket descriptions, check the Cylinder node
in the Geometry Nodes.

This patch adds color attributes to TexPaintSlot. This allows an easier selection
when painting color attributes.
Previously when selecting a paint tool the user had to start a stroke, before the
UI reflected the correct TexPaintSlot. Now when switching the slot the active
tool is checked and immediate the UI is drawn correctly.
In the future the canvas selector will also be used to select an image or image texture node
to paint on. Basic implementation has already been done inside this patch.
A limitation of this patch is that is isn't possible anymore to rename images directly from
the selection panel. This is currently allowed in master. But as CustomDataLayers
aren't ID fields and not owned by the material supporting this wouldn't be easy.
{F12953989}
In the future we should update the create slot operator to also include color attributes.
Sources could also be extended to use other areas of the object that use image textures
(particles, geom nodes, etc... ).

Currently, only Lightgroups that exist in the current view layer can be

The internal UI code already has support for search fields that accept
unknown input, so I just added that to the API and use it for lightgroups.
When a lightgroup is entered that does not exist in the current view layer
(e.g. because it's completely new, because the view layer was switched or
because it was deleted earlier), a new button next to it becomes active and
adds it to the view layer when pressed.

color attribute system.
This commit removes sculpt colors from experimental
status and unifies it with vertex colors. It
introduces the concept of "color attributes", which
are any attributes that represents colors. Color
attributes can be represented with byte or floating-point
numbers and can be stored in either vertices or
face corners.
Color attributes share a common namespace
(so you can no longer have a floating-point
sculpt color attribute and a byte vertex color
attribute with the same name).

The functionalities are divided into three versions of the operator:
* Left-Click
* Ctrl + Left-Click
* Double Click
All current functionalities and their defaults are as follows:
* Extrude Point: Add a point connected to an existing point.
Enabled for Left-Click.
* Extrude Handle Type: Type of the handles of the extruded points.
Can be either Vector or Auto. Defaults to Vector.
* Delete Point: Delete existing point.
Enabled for Ctrl + Left-Click.
* Insert Point: Insert a point into a curve segment.
Enabled for Ctrl + Left-Click.
* Move Segment: Move curve segment.
Enabled for Left-Click.
* Select Point: Select a single point or handle at a time.
Enabled for Left-Click.
* Move point: Move existing points or handles.
Enabled for Left-Click.
* Close Spline: Close spline by clicking the endpoints consecutively.
Defaults to True.
* Close Spline Method: The condition for Close Spline to activate.
Can be one of None, On Press or On Click.
Defaults to On Click for Left-Click and None for the others.
* None: Functionality is turned off.
* On Press: Activate on mouse down.
This makes it possible to move the handles by dragging immediately
after closing the spline.
* On Click: Activate on mouse release.
This makes it possible to avoid triggering the Close Spline
functionality by dragging afterward.
* Toggle Vector: Toggle handle between Vector and Auto handle types.
Enabled for Double Click on a handle.
* Cycle Handle Type: Cycle between all four handle types.
Enabled for Double Click on the middle point of a Bezier point.
The keybindings for the following functionalities can be adjusted from
the modal keymap
* Free-Align Toggle: Toggle between Free and Align handle types.
Defaults to Left Shift. Activated on hold.
* Move Adjacent Handle: Move the closer handle of the adjacent vertex.
Defaults to Left Ctrl. Activated on hold.
* Move Entire: Move the entire point by moving by grabbing on the handle
Defaults to Spacebar. Activated on hold.
* Link Handles: Mirror the movement of one handle onto the other.
Defaults to Right Ctrl. Activated on press.
* Lock Handle Angle: Move the handle along its current angle.
Defaults to Left Alt. Activated on hold.
All the above functionalities, except for Move Segment and
those that work with handles, work similarly in the case of Poly

This commit makes the dot grid used as background in the node editor
more visually stable when zooming in and out.
The dot grid now uses a continuously subdividing pattern, where
each level of subdivision divides the previous five times, similar to
the line grid in the 3D viewport.
The maximum for the "Grid Levels" theme setting is changed to 3, since
any further subdivisions are too small to be visible.
The "Grid Levels" value for the default themes "Blender Dark" and
"Blender Light" is therefore changed to 3, as well.

Currently this isn't used in the key-map, it will eventually
allow the 3D viewports tweak tool to match the behavior of other
editors that support tweaking a selection without first de-selecting
all other elements.
Meta-element selection now follows conventions for other picking
functions (e.g. EDBM_select_pick).
- Split meta-element find-nearest into a separate function.
- Cycle the meta-element starting from the active & selected
instead of comparing & setting a static variable.
- Order elements using depth (from front-to-back)
when cycling multiple elements.
- Add SelectPick_Params struct to make picking logic more
straightforward and easier to extend.
- Use `eSelectOp` instead of booleans (extend, deselect, toggle)
which were used to represent 4 states (which wasn't obvious).
- Handle deselect_all when pocking instead of view3d_select_exec,
de-duplicate de-selection which was already needed in when replacing
the selection in picking functions.
- Handle outliner update & notifiers in the picking functions
instead of view3d_select_exec.
- Fix particle select deselect_all option which did nothing.
As proposed in T95802, this adds buttons to a new column on the right to modify

improvements are planned. E.g. this does not yet expand collections (modifiers,

Vector properties with more than 3 items or matrices aren't displayed nicely
yet, they are just squeezed into the column. If this actually becomes a problem
there are some ideas to address this.

This patch adds edge selection support for UV editing (refer T76545).
Developed as a part of GSoC 2021 project - UV Editor Improvements.
Previously, selections in the UV editor always flushed down to vertices
and this caused multiple issues such as T76343, T78757 and T26676.
This patch fixes that by adding edge selection support for all UV
operators and adding support for flushing selections between vertices
and edges. Updating UV select modes is now done using a separate
operator, which also handles select mode flushing and undo for UV
select modes. Drawing edges (in UV edge mode) is also updated to match
the edit-mesh display in the 3D viewport.
Notes on technical changes made with this patch:
* MLOOPUV_EDGESEL flag is restored (was removed in rB9fa29fe7652a).
* Support for flushing selection between vertices and edges.
* Restored the BMLoopUV.select_edge boolean in the Python API.
* New operator to update UV select modes and flushing.
* UV select mode is now part of editmesh undo.
TODOs added with this patch:
* Edge support for shortest path operator (currently uses vertex path logic).
* Change default theme color instead of reducing contrast with edge-select.
* Proper UV element selections for Reveal Hidden operator.
