USD Import: fixed typo in comment.

USD Import: removed unused ImportSettings member.

ImportSettings::vel_scale was unused and has bee removed.

Fix T89233: Incorrect attribute remove warning for curves

The curve attribute delete function didn't return whether it was
successful or not.

Cleanup: change name of function

Fix some smaller review comments, WIP changes trying to implement different arg parsing

Enable UMM addon by default.

Added logic to enable the omni addon by default on
startup and when initially setting user preferences.
This appears to be working, but is probably not the
officially sanctioned approach to set defaults, so
this must be investigated further.

Raycast geometry node.

The //Raycast// node intersects rays from one geometry onto another.
It computes hit points on the target mesh and returns normals, distances
and any surface attribute specified by the user.

A ray starts on each point of the input //Geometry//. Rays continue
in the //Ray Direction// until they either hit the //Target Geometry//
or reach the //Ray Length// limit. If the target is hit, the value of the
//Is Hit// attribute in the output mesh will be true. //Hit Position//,
//Hit Normal//, //Hit Distance// and //Hit Index// are the properties of the
target mesh at the intersection point. In addition, a //Target Attribute//
can be specified that is interpolated at the hit point and the result
stored in //Hit Attribute//.

Fix T89234: Gpencil Separate doesn't copy settings in Stroke/Point mode

Some values were not copied from the old layer to the new one as Tint or Opacity factor.

Geometry Nodes: Add Curve Subdivision Node

This node creates splines with more control points in between the
existing control points. The point is to give the splines more
definition for further tweaking like randomization with white noise,
instead of deforming a resampled poly spline with a noise texture.

For poly splines and NURBS, the node simply interpolates new values
between the existing control points. However, for Bezier splines,
the result follows the existing evaluated shape of the curve, changing
the handle positions and handle types to make that possible.

The number of "cuts" can be controlled by an integer input, or an
attribute can be used. Both spline and point domain attributes are
supported, so the number of cuts can vary using the value from the
point at the start of each segment.

Dynamic curve attributes are interpolated to the result with linear
interpolation.

Cycles X: Initial support for the constant time rendering

Allows to limit render time, so that rendering will either happen
until all samples are finished, or the given time limit is reached.

Currently is only implemented for background and headless renders,
as those seems to benefit the most. In the viewport would still
like to investigate idea of keeping rendering until desired noise
floor is reached before adding extra settings there.

The usecases for the non-interactive (background, headless) renders
includes:

- Rendering a shot previews for movies.
- Ensuring some "bogus" frames do not stall the render farm.
- Allows to implement benchmark which will work reliable for both
very powerful and weak hardware configurations (as an example,
top-end GPUs and mobile GPUs) without requiring to wait forever
on a non-powerful hardware.

One of the tricky parts which is not solved in this version yet is
support of constant time rendering with multiple big tiles. However,
support of big tiles will be an addition on top of the existing code
as some sort of time limit would need to be enforced for every tile
(in other words, support of constant time render for multiple tiles
will be implemented on a higher level).

Cycles X: Re-arrange sampling panel

More explicit separate viewport from render settings. Makes it easier
and more clear to add settings which are only for preview or only for
the final render.

Among other thngs removed unused CYCLES_RENDER_PT_sampling_total.
Think better would be to call draw_samples_info for both viewport
and render samples.

Geometry Nodes: support minimum twist normal mode

The minimum twist mode is important because it allows creating
normals without sudden changes in direction. The disadvantage
of minimum twist normals is that the normals depend on all control
points. So changing one control point can change the normals
everywhere. The computed normals do not match the existing
code exactly, although they do match quite well on non-cyclic and
on some cyclic curves. I also noticed that the existing implementation
has some fairly simple failure cases that I haven't found in the new
implementation so far.

Geometry Nodes: fix ownership issue in spline to points conversion

Previously, `VArray_For_SplineToPoint` did not take ownership of the
virtual array leading to use-after-free errors.

Fix Cycles X shadow catcher artifacts

Were caused by matte object appearing in the division process.

This change makes it so the matte object is removed from the
combined pass before division, which solves artifacts caused
by anti-aliasing (the matte "bleeds" into the shadow catcher
and produces artifacts around the rim).

Additionally made certain parts more explicit and better
documented.

Geometry Nodes: improve node locking in evaluator

This makes the parts where a node is locked more explicit. Also, now the thread
is isolated when the node is locked. This prevents some kinds of deadlocks
(which haven't happened in practice yet).
