Clay strips was using it's own brush local matrix,
which wasn't quite compatible with texture matrices.
This could lead to brush textures not lining up with
the stroke dabs.
There was also a bug where the stroke was starting
20 pixels into the stroke, which is much higher than
necassary to derive the initial rake angle.
Notes:
* The clay strips brush now uses SCULPT_cube_tip_init
to calculate the local brush matrix.
* SCULPT_cube_tip_init now accepts custom brush location
and radius arguments.
* The mouse sample preroll used to calculate initial brush
rotation angle is now smaller than the update interval.
* Clay strips now supports tip_scale_x, which has also
been added to DNA defaults.
`use_ambient_occlusion` is a legacy property and not
connected to anything. The clip editor still write
to it for enabling the ambient occlusion renderpass.
This change will remove the legaccy option and
won't enable ambient occlusion pass anymore due
to visual and performance impact.

At a glance, it can be hard to see if a Shape Key has been muted or not.
This change greys out all the UI elements, instead of just the current value number.
All the functionality still works the same, purely a visual change.

All probes (including the world background probe) are stored in a single texture. Each probe
can be of any resolution as long as it is a power of 2 and not larger than 2048. So valid options
are (2048x2048, 1024x1024, 512x512, etc).
Each probe can be stored in their own resolution and can be set by the user.
> NOTE: Eventually we would like to add automatic resolution selection.
The probes are packed in an 2d texture array with the dimension of 2048*2048. The number of
layers depends on the actual needed layers. If more layers are needed the texture will be recreated.
This can happen when a new reflection probe is added, or an existing reflection probe is made visible
to the scene or its resolution is changed.
### Octahedral mapping
Probes are rendered into a cubemap. To reduce memory needs and improve sampling performance the cubemap
is stored in octahedral mapping space. This is done in `eevee_reflection_probe_remap_comp.glsl`.
The regular octahedral mapping has been extended to fix leakages at the edges of the texture
and to be able to be used on an atlas texture and by sampling the texture once.
To reduce sampling cost and improve the quality we add an border around the
octahedral map and extend the octahedral coordinates. This also allows us to
generate lower resolution mipmaps of the atlas texture using 2x2 box filtering
from a higher resolution.
### Subdivisions and areas
Probes data are stored besides the texture. The data is used to find out where the probe is stored
in the texture. It is also used to find free space to store new probes.
This approach ensures that we can be flexible at storing probes with different
resolutions on the same layer. Lets see an example how that works
Code-wise this is implemented by `ProbeLocationFinder`. ProbeLocationFinder can view a texture in a
given subdivision level and mark areas that are covered by probes. When finding a free spot it returns
the first empty area.
**Notes**
* Currently the cubemap is rendered with a fixed resolution and mipmaps are generated in order to
increase the quality of the atlas. Eventually we should use dynamic resolution and no mipmaps.
This will be done as part of the light probe baking change.

The "Align Rotation" operator in the UV editor was producing
unexpected results if an image was displayed with non-square aspect
ratio. This change adds the "Correct Aspect" option to the operator.
To ensure consistency between the UV unwrapping operators, the
`UV > Follow Active Quads` operator will now use 3D selection when
called from the 3D editor, and UV selection when called from the
UV editor.
This reverts commit d53862351d.
After conducting tests with artists at the studio, it was observed that
altering the Transform Modal Maps caused significant disruption due to
the heavy reliance on the "Proportional Editing" and "Automatic
Constraint" features.
Considering this, it is now deemed more beneficial to provide users
with the choice of adapting their muscle memory to the new changes.

This PR adds support to override the world with the HDRI of the
viewport.
Blurring of the background and camera based rotation isn't supported.
Switching the HDRI would still use the world diffuse light as that is
baked into the irradiance cache.
These issues have been added to #109646

Port Ambient Occlusion to EEVEE Next.
Add support for the AO Node and the AO RenderPass.
AO shading integration is still missing.
This also fixes the Shadow RenderPass.

Similar to curves, the ".selection" attribute is used to store selection.
Selection isn't visualized in the viewport yet, but this should be added
at some point anywya. See f89b32382a.
This PR adds a new operator to run a node group on object geometry.
Only curves sculpt mode is supported for now, to simplify the design.
A new geometry node editor context to edit operator groups is also
added. This allows changing any node group, rather than only node
groups that are part of the active modifier context.
3D viewport menus are added with any geometry node group
asset in a catalog that contains the `Operator` tag. Currently Blender
must be restarted to refresh the list of available operators.
This is only the first phase of the node group operator feature.
Many more features will be added in next steps.
See #101778

Similar to 5f16e24cc9, this adds support for edit mode
to the point cloud object type, which is currently hidden behind an
experimental option. No interaction is possible yet, for now this
can be used as a testing for a node-group-operator-only mode.
As suggested in #108669, the "Navigate during Transform" option has
been removed and this feature works by default.
Now if you press `G`, `R` or `S` to move, rotate or scale an object you
can also navigate in the viewport.
Note that this update modifies the default keymap.
Now pressing `Alt` is required for the following modals:
- `PROPORTIONAL_SIZE_UP`,
- `PROPORTIONAL_SIZE_DOWN`,
- `PROPORTIONAL_SIZE`,
- `AUTOIK_CHAIN_LEN_UP`,
- `AUTOIK_CHAIN_LEN_DOWN`,
- `AUTOCONSTRAIN`,
- `AUTOCONSTRAINPLANE`.

- "Front"/"Back": 'put something at the front/back' or 'the front/back
face of something'. (e. g. the Empty Image options, Depth and Side
option, both use the same strings as enum, which should be avoided
in some languages).
- "Flip": invert, as in normals, or mirror, as in an image.
- "Path": a path to a resource, in general a file but sometimes a
datablock, as opposed to a trajectory in space.
- "Join": disambiguate for the Grease Pencil operator, which may use a
different word as that for meshes.
- "Wave": an ondulating motion, as opposed to a fluid dynamics motion.
- "Step": can mean the distance between two things, or a number of
times to do something. In this case it is better to use the plural.
- "Edge": generally the edges of a mesh, but can also mean edge
detection. Additionally, it was used for the option to enable
Freestyle. This was changed to "Use Freestyle".
- "Boundary": the limit of a grease pencil drawing for filling
purposes, as opposed to the external limit of a (non-manifold) mesh.
- "Rotations": can be translated to something like "Turns", in the
context of a spiral.

Adds a new UI template to view the current layer tree of the active Grease Pencil object.
This UI tree view implements the following features (for now):
- Displaying all the layers with their names and highlighting the active layer.
- Changing the active layer by clicking on an item.
- Adding new layers (using a new operator).
- Removing the active layer (using a new operator).
- Renaming a layer.

Added selection support to the Follow Active Quads operator.
Simplified code and added comments.
Also added new error codes:
* STATUS_ERR_MISSING_UV_LAYER
* STATUS_ERR_NO_FACES_SELECTED
Pull Request: https://projects.blender.org/blender/blender/pulls/109095
This was due to a wrong mapping of tools in the toolbar.
The fix makes sure that the correct selection tools are used for the
old grease pencil objects.
In order to accomplish this properly, the new grease pencil objects
use their own edit mode context.
This way the two objects are cleanly seperated.
This refactors how a geometry nodes node tree is converted to a lazy-function
graph. Previously, all nodes were inserted into a single graph. This was fine
because every node was evaluated at most once per node group evaluation.
However, loops (#108896) break this assumption since now nodes may be
evaluated multiple times and thus a single flat graph does not work anymore.
Now, a separate lazy-function is build for every zone which gives us much
more flexibility for what can happen in a zone. Right now, the change only
applies to simulation zones since that's the only kind of zone we have.
Technically, those zones could be inlined, but turning them into a separate
lazy-function also does not hurt and makes it possible to test this refactor
without implementing loops first. Also, having them as separate functions
might help in the future if we integrate a substep loop directly into the
simulation zone.
The most tricky part here is to just link everything up correctly, especially
with respect to deterministic anonymous attribute lifetimes. Fortunately,
correctness can be checked visually by looking at the generated graphs.
The logging/viewer system also had to be refactored a bit, because now there
can be multiple different `ComputeContext` in a single node tree. Each zone
is in a separate `ComputeContext`. To make it work, the `ViewerPath` system
now explicitly supports zones and drawing code will look up the right logger
for showing inspection data.
No functional changes are expected, except that the spreadsheet now shows
"Simulation Zone" in the context path if the viewer is in a simulation.
The default value of the "sharp_face" attribute is False like other
boolean attributes. That mistakenly changed behavior in addons
that created meshes with `Mesh.from_pydata`. To fix, add an
argument with a default value that maintains the behavior
from before, and add convenience, `shade_smooth` and
`shade_flat` methods.
