This replaces the trilinear interpolation with manually
placed samples to avoid most light leak.
Add two new parameters to bias the sampling position:
- Normal bias
- View bias
Move the irradiance smoothing parameter per grid.

Implementation of the hard eraser for grease pencil.
The tool "cuts" the strokes, meaning it removes points that are inside the eraser's radius, while adding points at intersections between the eraser and the strokes.
Note that this does not implement the "Stroke" and "Dissolve" mode of the eraser yet.

Writing this file in specific places is not the responsibility of that
utils module code. this is for caller's logic to handle (in this case,
mainly the update UI translations add-on).
This patch merges the two operators `Push Pose from Rest Pose`
and `Relax Pose from Rest Pose` into one
new operator `Blend Pose with Rest Pose`
The operator has a default range of -1/1 with a default of 0.
The functionality of `Relax Pose from Rest Pose` is on the positive axis
and `Push Pose from Rest Pose` on the negative.
This is a breaking change so ideal for 4.0

Adds the UI for layer opacity in the layer panel.
Currently layer blending rendering is not implemented, so the last layer's opacity will affect all of the layers.

This PR introduces baking reflective light from light probes. Light probes
are baked on the fly when the light probe data has changed. It doesn't update
directly when other scene data is changed in the viewport.
When doing image rendering the light probes are updated on each frame.
Currently the world probe and closest reflection probe are composited
together in shader. This allows different resolutions. We expect that we
eventually composite it before usage. This would improve the performance.
Unclear if we would support both compositing options eventually.

Implements the Butterworth Filter
(https://en.wikipedia.org/wiki/Butterworth_filter) for smoothing FCurves.
This filter is ideal for smoothing dense data, like motion capture recordings.
It has the advantage of keeping the shape of the curve
intact while reducing minimal fluctuations.
The disadvantage is the impulse response has a twang,
meaning extreme spikes cause fluctuations to either side.
The implementation is based on the GPL code found here:
https://exstrom.com/journal/sigproc/dsigproc.html
In order to avoid phase shifting, the filter is run forward and backward,
effectively doubling the filter order.
The Redo panel offers the following options
* Frequency Cutoff: 0-n value, where 0 means it cuts everything
so the curve will become straight, the max value is the Nyquist frequency
and depends on the frame rate and the "Samples per Frame" option
* Filter Order: Higher values mean the frequency cutoff is steeper
* Samples per Frame: Before the filter is applied, the curve is resampled
at this interval to avoid errors when there are uneven spaces between frames.
If the keys are on subframes, e.g. a 60fps file in a 30fps scene, increase this value to 2
* Blend: 0-1 value to blend between the original curve and the filter result
* Blend In/Out: The number of frames at the start and end for which
to blend between the filtered and unfiltered curve.
This can help reduce any resulting jumps in the animation at the selection border
The operator can be called from the Key menu. (Key->Smooth->Butterworth Smooth)

Move the node previews to the overlay region, atop each node.
It allows nodes to keep the same size when the preview is toggled,
which is more convenient for large nodes and large nodetrees.
The preview has to be drawn from `node_draw_extra_info_panel`
because there could be overlapping between info text and the preview.
When the node is out of the view, it also has to make sure that the
preview is also out of the view before exiting the draw function.

When the selection mode in the Grease Pencil tool settings changes,
the selection domain of all curves in the active Grease Pencil object
has to change.
This PR handles that conversion. Point selections are converted to
curve selection and vice versa.
Note: this PR only takes care of selection modes 'Point' and 'Stroke'.
'Segment' mode is handled in a separate PR (#109221).

This adds support for running a set of nodes repeatedly. The number
of iterations can be controlled dynamically as an input of the repeat
zone. The repeat zone can be added in via the search or from the
Add > Utilities menu.
The main use case is to replace long repetitive node chains with a more
flexible alternative. Technically, repeat zones can also be used for
many other use cases. However, due to their serial nature, performance
is very sub-optimal when they are used to solve problems that could
be processed in parallel. Better solutions for such use cases will
be worked on separately.
Repeat zones are similar to simulation zones. The major difference is
that they have no concept of time and are always evaluated entirely in
the current frame, while in simulations only a single iteration is
evaluated per frame.
Stopping the repetition early using a dynamic condition is not yet
supported. "Break" functionality can be implemented manually using
Switch nodes in the loop for now. It's likely that this functionality
will be built into the repeat zone in the future.
For now, things are kept more simple.
Remaining Todos after this first version:
* Improve socket inspection and viewer node support. Currently, only
the first iteration is taken into account for socket inspection
and the viewer.
* Make loop evaluation more lazy. Currently, the evaluation is eager,
meaning that it evaluates some nodes even though their output may not
be required.

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.

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.

Blurring of the background and camera based rotation isn't supported.
Switching the HDRI would still use the world diffuse light as that is

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.

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`.
