include D9925: NLA Tweak Mode: Evaluate Upper Stack

Merge branch 'master' into temp-gpencil-bezier-v2

GPencil: Curve circle select

There are currently some updates happening while the mouse is moving,
that make the handles flicker.

GPencil: Fix stroke selection

We want to keep the stroke and curve selection seperate. Only when a
conversion happens do we want to sync the selection.

Merge branch 'master' into temp-gpencil-io

Merge branch 'master' into greasepencil-object

Cycles: modify integrator kernels to check if they need to execute

And do some renaming for clarity.

GPencil: Fix Linux compiler warnings

These warnings were not visible with Windows compiler.

Merge branch 'master' into temp-gpencil-interpolate

Cycles: Properly initialize camera rays

The idea is to pass KernelWorkTile to the generate_camera_rays
kernel so that it can have access to screen-space coordinates.
Some fields of the KernelWorkTile are unused and are either to
be removed in the future, or a simplified version of a struct
is to be used.

The device side of changes is related on making it to queue is
aware of where in the bug tile if is operating on. Currently
done as an API of DeviceQueue, and with time might become more
clear whether such work tile concept should only be done for
path tracing related queue.

The path tracer change is rather annoying and a bit messy: it
evaluates the render graph for every pixel in a progressive
refine manner. It is slow and single threaded, and code is not
folded very flexible yet. The good thing is that it allows to
make it so kernels to output proper data.

The output kernels needs an adjustment, so that they write to
an offset within the render buffer. Only modified the surface
kernel, because otherwise other kernels will override the value
and make it so nothing is visible.

Cycles: Cleanup, rename WorkTile to KernelWorkTile

Makes it a clear separation between device and kernel types.

Working circle primitive, except for rotation

USD import Set Material Blend option.

New Set Material Blend option which, if enabled together
with the UsdPreviewSurface option, will automatically set
the material blend method based on the shader's opacity
and opcityThreshold inputs.

Lineart: Fix memory leak in lineart_ops.c (Early return caused memory in list not freed).

Lineart: Fixed uninitialized variables.

cleanup, review interface

store deltas in half-floats, implement logic for vertices

Merge branch 'master' into geometry-nodes-mesh-primitives

It stopped working

More progress towards a prototype
