The GPU compositor crops the viewed images to the render resolution.
While the original size and content of the input to the viewer should be
retained as is.
This patch fixes that by specializing compositors that can use composite
outputs to be able to view images of any arbitrary size. This is still
missing the translation offset of the viewer, but this shall be tackled
separately.
The push constant `double_sided` and `Surfel.double_sided` collided. Due
to the macros that the vulkan backend is creating it isn't possible to
use the same attribute name as an existing push constant.

I had to do a huge refactor in order to do this.
The way ReflectionProbe were referencing the UBO
data was conflicting with the way EEVEE-Next
object should behave.
So like light, shadow and irradiance grids, every
probe is synced with it's GPU data as base struct
and the data is just copied into the UBO
when using `set_view`.
To simplify many parts of the reflection probe
code, I isolated the atlas coordinate of a probe
to its own struct that can be easily copied.

Update to the new naming convention for `Light Probes`:
`Reflection Cubemap` -> `Sphere`
`Reflection Plane` -> `Plane`
`Irradiance Grid` -> `Volume`
Note that this breaks the Python API (`bpy.types.LightProbe.type`).

This PR reuses the scene specific reflection probe resolution for all
reflection light probes in the scene. The target is to have a automatic
detection for the resolution. But as long as we don't have a mechanism
for detection it is better to not introduce a new UI element that will
be removed within the foreseen future.
This setting is currently used by EEVEE and EEVEE-Next. EEVEE supports
resolutions upto 4096px. This will be clamped to 2048 when using
EEVEE-Next.
The motivation for this is that EEVEE-Next will soon replace
EEVEE and 4096 can then be removed from the choices that the user can
made. Adding as separate option could need synchronization, and that
option would also be temporary as it will be removed by the resolution
detection mechanism.

This traces planar lightprobe captures just like
the screen-space tracing does.
This is implemented as a separate shader that
loads the ray before the screen trace and
check if it can be traced against any available
planar probe. If it does it marks the ray as
traced (negative pdf) so that the screen tracing
pass does not override the result or try to
trace it.

After performing a transformation EEVEE-Next non-stops resets the
sampling. The cause is that the `recalc` flag that are stored in the
Object isn't consumed. When transforming it was always filled with
`ID_RECALC_TRANSFORM` and kept on resetting the sampling.
Regression introduced by PR #113252.

The selection engine has some complex tricks that improve performance.
These are:
- Only draws objects whose bounding box intersects the selection
threshold;
- If the viewport or objects are not "dirty", it does not clean the
texture IDs and only adds objects that have not yet been drawn;
- Only updates the depth buffer if a new object is drawn;
- Skip drawing if no object is found;
These tricks were initially implemented so that this engine could be
used for snapping.
But this initial idea has changed and now the engine is only used to
select Vertices, Edges or Faces.
Due to this limited use, these tricks bring no real benefit.
In fact, it's even worse with the Retopology Overlay, as it forces the
Depth buffer to be redrawn.
This commit removes these tricks and only keeps those that indicate
whether the drawing needs to be updated.

This PR adds support for Intel ARC GPUs. Due barriers inside a non
uniform control flow the Intel ARC can stall the whole system.
The cause is that a barrier is used, but some threads in the shader
have completed. The barriers might wait until it gets the signal from
the exited threads and stalls the system.
Although some implementations support it it is safer to limit the
number of HiZ levels.

When the first planar probe is added to the scene, or the last probe
is removed from the scene the samples needs to be reset. This removes
artifacts when only a single sample is used.

Move the three current 'status variables' (stop, update and progress)
into a single 'WorkerStatus' struct. This is cleaner and will allow for
future workin this area without having to edit tens of 'startjob'
callbacks signatures all the time.
No functional change expected here.
Note: jobs' specific internal code has been modified as little as
possible, in many cases the job's own data still just store pointers to
these three values. Ideally in the future more refactor will be using a
single pointer to the shared `wmJobWorkerStatus` data instead.

When deleting the last planar probe in the scene the color and
depth textures are resized with 0 layers. This isn't allowed.
This is fixed by adding an early exit and creating dummy textures.

This PR is contains the initial capture pipeline for planar probes.
It requires work to generate the correct view to capture and to include
the result during ray tracing. These will be developed in a separate PR.
This PR detects if a planar probe is active in the scene. If this is
the case the planar probe pipeline will be activated. During rendering
this is done by querying the depsgraph, during viewport drawing this
is done during sync. If an planar probe is detected and the pipeline
wasn't activated. The pipeline will be activated and the sampling
will be reset to ensure the pipeline is filled with all objects.
Per object the user can set the visibility of the object in planar
reflections.

For a reflection plane the resolution and clipping offset can be set.
EDIT: Resolution option was removed because too complex to
implement with the little time we have at the moment.

This moves the thickness from shadow map
approximation out of the lighting and shadowing
loop. Instead of using the thickness from
the shadow tracing from each individual light
before SSS evaluation, we precompute the
average thickness from all shadowed light.
This is then mixed with the nodetree thicknes.
## SSS Translucency
This add back SSS transmission support by using
the mentionned thickness computation, and applying the
transmission profile on it. This is then applied on top of a
flipped normal LTC computation.

This allow splitting shadow and light evaluation.
This is the first step to deferred shadowing.
The evaluate closure types can be dynamically
set which mean we can have arbitrary BSDF
evaluation inside the same shader.
This also contain some refactor to `light_lib.glsl`
for more consistency and less clutter.
Note that this breaks the SSS translucency
as the shadow evaluation changes for these.
A new solution for this feature is to be found

This refactor the lightprobes sample so that we always query
the spherical probe and the volume probe.
Then, given the BSDF type, we reconstruct the incoming radiance
differently depending on the ray probability blending between
the spherical and volume probe depending on ray probability.
Moreover, we implement cubemap normalization using
volume probe spherical harmonic data at spherical probe
position and at the shading point position.

Optimize Workbench performance so it's on par with the previous
implementation.
Most of these changes are barely noticeable on powerful GPUs,
but can cause a notable performance improvement on old or low-end
hardware.
* Avoid unnecessary texture copies and draw directly to the viewport
textures.
* Optimize-out depth/stencil reads, using stencil testing instead.
* Avoid using `Texture::clear` and use framebuffer clears instead.
* Avoid framebuffer state changes (always use the same attachments).
* Avoid constant variation of acquired `TextureFromPool`s.
Fix#113010

Fixed version of #112544 (reverted).
`DRW_drawdata_get` reuses the same `DrawData` for all duplis,
so they all end up using the same `ObjectHandle` and `ObjectKey`,
which breaks motion vectors.
* Don't rely on `DRW_drawdata_get` for storing `ObjectKey`s.
* Simplify `ObjectKey`.
This also solves the issue of objects created "on the fly" always having
the `ID_RECALC_ALL` flag.

This fixes several issues related to using reflection probes in EEVEE-Next.
- When using a single sample, the reflection probes weren't always updated.
- Composite world background in reflection probes
- Removing reflection probes wasn't working
- Update UBO when world and reflection probes are active in the scene.

This PR implements an initial drawing tool that can already be used for testing.
While this is not fully feature complete (compared to the current grease pencil draw tool) the following is already implemented:
* Pressure support for radius and opacity.
* Material color and vertex color support.
* New active smoothing algorithm based on curve fitting.
* Simplify algorithm as a post-process step.
Some deliberate limitations include:
* The drawing plane is always the front plane. Drawing on surfaces is also not supported.
*
The current approach has not been optimized for performance yet. The goal was to have a straightforward implementation
first and then focus on performance later.
There are numerous parameters in the code that are hard-coded for now. These should be exposed at some point, potentially as user settings.

Optimization of EEVEE Next's Virtual Shadow Maps for TBDRs.
The core of these optimizations lie in eliminating use of
atomic shadow atlas writes and instead utilise tile memory to
perform depth accumulation as a secondary pass once all
geometry updates for a given shadow view have been updated.
This also allows use of fast on-tile depth testing/sorting, reducing
overdraw and redundant fragment operations, while also allowing
for tile indirection calculations to be offloaded into the vertex
shader to increase fragment storage efficiency and throughput.

For some reasons, `WM_jobs_stop` and `WM_jobs_kill` would use their own
'type' of function pointer - and not even a matching one!
Among (many) other reasons why this was bad, it required very stupid
casting from code using these functions - and made editing wmJob `startjob`
signature needlessly complicated.
When the scene has reflection probes the sampling would be reset
each frame making the viewport always redraw and not resolve.
The reason was a logic error that was introduced when we introduced
a less flickering update for reflection probes.

The probe capture pipeline still had some bindings from the previous
implementation. This could result in overwriting the `gbuf_header_tx`
with the incorrect texture as it was sharing the same binding.
