This was caused by spatial denoising pass sampling invalid data.
This patch make it so that there is one padding tile all
around the denoise area.
This simplifies the denoise shader too.
This is a bit wasteful to dispatch tracing tiles for clearing
and a better solution would be to use a separate shader and
tile list only for this purpose.
Replaces all usage by the the gpu_shader_math
equivalent. This is because the old shader
library was quite tangled.
This avoids dependency hell trying to
mix libraries.
Changes are split into isolated commits until
I had to do mass changes because of inter-
dependencies.

When drawing the image editor the depth of the geometry is set to -1.
This will be clipped in Vulkan, but is valid in OpenGL. This PR patches
the shader to be inside the range that both Vulkan and OpenGL support.
This ensures that images are visible in the image editor.

With the shift to GPU-driven rendering pipeline,
the SSBO vertex fetch paradigm used to
implement workbench shadows on Metal
instead of utilising the geometry shader
path no longer worked correctly.
This is because the draw submission
required vertex amplification up-front,
based on the expected output geometry
amount for a given input geometry.
This WIP patch aims to resolve this
issue through addition of API to
enable the features within the
GPU driven pipeline.

`eevee_shadow_page_tile_store` shader uses `VIEWPORT_INDEX` and `LAYER`.
Both use an optional extension in OpenGL and Vulkan. When the extension
isn't available a geometry shader is injected to emulate the
extension. The generated geometry shader requires `instance_name` to be
set. This wasn't the case for `eevee_shadow_page_tile_store` shader.
This PR also adds a detection for incompatible shader infos.
- Shaders that use `VIEWPORT_INDEX` or `LAYER` cannot have a geometry stage.
This check is done in debug and release builds.
- Shaders that use a fallback shader should have instance names set in
the stage interfaces. This check is only done in debug builds.

This adds `GreasePencilEditHints` and correctly implements
`crazyspace::get_evaluated_grease_pencil_drawing_deformation`
to support querying the deformation of points after evaluation.
This is needed for users to properly select points in edit mode while
seeing the effects of the modifiers.

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`).

Pass the mesh to the drawing functions so it doesn't have to be
retrieved from the PBVH. It's nice to rely less on the PBVH `me`
pointer, since it's a fairly ugly "back pointer" which isn't necessarily
good design.
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.
