When the "fully flat" state comes from "sharp_edge" and "sharp_face"
doesn't exist, we need to check for that for every face when extracting
normals. Eventually these loops should be unrolled so we don't have a
function call per face. That would remove the cost of this check.
The build scripts are still referring to gpu tests as being opengl.
Although they can also use Metal or Vulkan. This PR only replaces
the work `opengl` with `gpu` for build options.
Special note is that the windows argument `with_opengl_tests` is
also replaced with `with_gpu_tests` for consistency.

This patch adds an alternative path for devices/OSs
which do not support native texture atomics in Metal.
Support is encapsulated within the backend, ensuring
any allocated texture with the USAGE_ATOMIC flag is
allocated with a backing buffer, upon which atomic
operations happen.
The shader generation is also changed for the atomic
case, which instructs the backend to insert additional
buffer bind-points for the buffer resource. As Metal
also only supports buffer-backed textures for
textureBuffers or 2D textures, TextureArrays and
3D textures are emulated within a 2D texture, with
sample locations being indirected.
All usage of atomic textures MUST now utilise the
correct atomic texture types in the high level shader
and GPUShaderCreateInfo declarations.

This adds a new hybrid mode where the light and lightprobe
textures are bound to the gbuffer pass and used by
shaders that use ShaderToRGBA.
The counterpart is that these shaders have less texture
slots available but still two more than the Blended
materials.
These materials will correctly write to the AOVs and
render passes.
This is not too invasive in terms of implementation. The
only quirk was that we needed another fragment shader to
simplify the dependencies on the resources. But if we ever
get pre-processor support in our include / require system
this could be cleaned up.
This fixes a case where the source was set but the
internal pointers for binding were not updated.
This also tag for update internally.
Cleanup and remove the redundant tagging.
This also use the planar depth buffer as layer view.
All the relevant code is C++ now, so we don't need to complicate things
with the trip through C anymore. We will still need some wrappers, since
opensubdiv is an optional dependency though. The goal is to make it
simpler to remove the unnecessary/costly abstraction levels between
Blender mesh data and the opensubdiv code.
This de-duplicate some passes in the raytracing
pipeline and make it more ready for adoption
of arbitrary closure evaluation. This last part
means the removal of some per closure type
options.
The put in common the tile classification step
that is now done only once for all 3 closure
type. Also add some speedup to the tile
compaction phase that is now only twice
faster.
The horizon-scan setup was also de-duplicated
and run only if needed, which can save up to
0.5ms is complex scenes.
However, this moves the max-roughness and and
resolution scaling to a common parameter.
This is to be able to support arbitrary closure
evaluation where multiple closure with conflicting
parameters could be evaluated in one tracing pass.

"mesh" reads much better than "me" since "me" is a different word.
There's no reason to avoid using two more characters here. Replacing
all of these at once is better than encountering it repeatedly and
doing the same change bit by bit.
Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

This PR makes it so that locked materials as well as hidden materials will not have their edit points and edit lines visible.
Note: Previously in grease pencil, strokes with hidden materials would still display the edit lines. This behavior is now fixed in GPv3.

This allows for parallel processing of refraction.
Also fix a limitation of using AO node in
refraction materials.
This is needed for the grouping of raytracing
passes.
This increases VRAM consumption a bit (8MB for fullHD
frame) but has no impact on performance.
This include a needed fix to the `draw::Texture::swap`.
### Later work
- Limit the memory overhead to the cases where it is needed.

This adds a tile classification pass to the gbuffer.
This is then compact into streams of tiles for each
complexity level of lighting evaluation.
The benefit over a simpler approach of using a per
object stencil value is that we can have a per
tile granularity of the lighting complexity.
To avoid quad overshading, we use a prepass that
tags different stencil values for each complexity
level. This allows to still use a fullscreen quad
for the light evaluation pass and remove the
diagonal overshading cost.
This doesn't use compute shader at all to leverage
render pass merging and in-tile memory loads.
Using `atomicOr` for adding together the `eClosureBits`
revealed to be too slow. Using multiple non-atomic
writes to many data values is faster and not much
memory hungry.
### Performance
The whole tile scheduling process takes ~70µs for
a half covered 3800x790 framebuffer and doesn't
get much more slower than this.
Using simpler lighting shader helps reduce the cost
of the lighting pass by half in most common cases.
SSS materials stay the most costly.

This PR implements the Lookdev (HDRI) Spheres overlay for EEVEE-Next. There are
also improvements for lookdev:
* Scene lighting (direct and indirect are) applied to the spheres.
* Shadow is applied to the spheres.
This is done by virtually placing the balls at the near clip plane of the camera/viewport.

NDEBUG is part of the C standard and disables asserts. Only this will
now be used to decide if asserts are enabled.
DEBUG was a Blender specific define, that has now been removed.
_DEBUG is a Visual Studio define for builds in Debug configuration.
Blender defines this for all platforms. This is still used in a few
places in the draw code, and in external libraries Bullet and Mantaflow.

Also use const arguments, move a null check from the callback to the
PBVH function, and reorganice the PBVH code to be in a consistent
place in the file and to simplify the logic.
Move the contents of `ANIM_bone_collections.h` into its C++
`ANIM_bone_collections.hh` sibling. Blender is C++ by now that we can do
without the C header.
No functional changes.
