- Use usernames in tags, as noted in code-style.
Due to shader global scope emulation via class interface, global constant arrays in shaders are allocated in per-thread shader local memory. To reduce memory pressure, placing these constant arrays inside function scope will ensure they only reside within device constant memory. This results in a tangible 1.5-2x performance uplift for the specific shaders affected.

This patch adds support for compilation and execution of GLSL compute shaders. This, along with a few systematic changes and fixes, enable realtime compositor functionality with the Metal backend on macOS. A number of GLSL source modifications have been made to add the required level of type explicitness, allowing all compilations to succeed.
GLSL Compute shader compilation follows a similar path to Vertex/Fragment translation, with added support for shader atomics, shared memory blocks and barriers.
Texture flags have also been updated to ensure correct read/write specification for textures used within the compositor pipeline. GPU command submission changes have also been made in the high level path, when Metal is used, to address command buffer time-outs caused by certain expensive compute shaders.

Extract:
- EEVEE: Compiling Shaders (the same message exists in EEVEE Next, but
it uses string concatenation and I don't know yet how to deal with
those--see T92758)
Disambiguate:
- Pan (audio, camera)
- Box (TextSequence)
- Mix (noun in constraints, GP materials)
- Volume (object type, file system)
- Floor (math integer part, 3D viewport horizontal plane)
- Impossible to disambiguate the constraint name because
bConstraintTypeInfo doesn't have a context field.
- Show Overlay (in the sequence editor, use the same message as other
editors to avoid a confusion with the Frame Overlay feature, also
called "Show Overlay")
Additionally, fix a few issues reported by Joan Pujolar (@jpujolar)
in T101830.

- Use the C++ `math` namespace functions
- Use `std::array` for arrays with size known at compile time
- Use `MutableSpan` instead of reference to array

Image Transform use linear or nearest sampling during editing and exporting.
This gets sampling is fine for images that aren't scaled. When sequencing
however you mostly want use some sort of scaling, that leads to poorer
quality.
This change will use sub-sampling to improve the quality. This is only
enabled when rendering. During editing the subsampling is disabled to
keep the user interface reacting as expected.
Another improvement is that image transform is stopped at the moment
it hadn't sampled at least 4 samples for a scan line. In that case we
expect that there are no further samples that would change to result.
In a future patch this could be replaced by a ray/bounding bo intersection
as that would remove some unneeded loops in both the single sampled and
sub sampled approach.
`PBVH_Leaf` nodes are now split into a new `PBVH_TexLeaf`
node type when using the paint brush. These nodes are
split by image pixels, not triangles. This greatly
increases performance when working with large
textures on low-poly meshes.

Rewrite of the Workbench engine using C++ and the new Draw Manager API.
The new engine can be enabled in Blender `Preferences > Experimental > Workbench Next`.
After that, the engine can be selected in `Properties > Scene > Render Engine`.
When `Workbench Next` is the active engine, it also handles the `Solid` viewport mode rendering.
The rewrite aims to be functionally equivalent to the current Workbench engine, but it also includes some small fixes/tweaks:
- `In Front` rendered objects now work correctly with DoF and Shadows.
- The `Sampling > Viewport` setting is actually used when the viewport is in `Render Mode`.
- In `Texture` mode, textured materials also use the material properties. (Previously, only non textured materials would)
To do:
- Sculpt PBVH.
- Volume rendering.
- Hair rendering.
- Use the "no_geom" shader versions for shadow rendering.
- Decide the final API for custom visibility culling (Needed for shadows).
- Profile/optimize.
Known Issues:
- Matcaps are not loaded until they’re shown elsewhere. (e.g. when opening the `Viewort Shading` UI)
- Outlines are drawn between different materials of the same object. (Each material submesh has its own object handle)

AMD GPUs do not appear to produce consistent results with other GPUs when using textureGather in the Metal backend. Disabling for now to ensure correct function of outline rendering.

The same logic from D17025 is used in other places in the curve code.
This patch uses the class for the evaluated point offsets and the Bezier
control point offsets. This helps to standardize the behavior and make
it easier to read.
Previously the Bezier control point offsets used a slightly different standard
where the first point was the first offset, just so they could have the same
size as the number of points. However two nodes used a helper function
to use the same `OffsetIndices` system, so switch to that there too.
That requires removing the subtraction by one to find the actual offset.
Also add const when accessing data arrays from curves, for consistency.

These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).
This allows an engine to perform GPU side view specification and let the
draw manager extract the culling informations (bounds).
To this end, the matrices ubo gets exposed to be able to write to it.
`compute_procedural_bounds()` need to be explicitely called before any
main pass using the culling result.
This changes how we access the points that correspond to each curve in a `CurvesGeometry`.
Previously, `CurvesGeometry::points_for_curve(int curve_index) -> IndexRange`
was called for every curve in many loops. Now one has to call
`CurvesGeometry::points_by_curve() -> OffsetIndices` before the
loop and use the returned value inside the loop.
While this is a little bit more verbose in general, it has some benefits:
* Better standardization of how "offset indices" are used. The new data
structure can be used independent of curves.
* Allows for better data oriented design. Generally, we want to retrieve
all the arrays we need for a loop first and then do the processing.
Accessing the old `CurvesGeometry::points_for_curve(...)` did not follow
that design because it hid the underlying offset array.
* Makes it easier to pass the offsets to a function without having to
pass the entire `CurvesGeometry`.
* Can improve performance in theory due to one less memory access
because `this` does not have to be dereferenced every time.
This likely doesn't have a noticable impact in practice.

Struct members loc/size were misleading as they read as if the object
data stored object level transform channels. Rename these to match RNA
with a `texspace_*` prefix to make it clear these struct members only
apply to texture-space transform.
Also rename ME_AUTOSPACE & ME_AUTOSPACE_EVALUATED to
ME_TEXSPACE_FLAG_AUTO & ME_TEXSPACE_FLAG_AUTO_EVALUATED.
ViewCullingData::corners (vec4) was casted to a BoundingBox (vec3), so the frustum corners were uploaded in the wrong format to the GPU.
Now the ViewCullingData::corners are used directly without casting, since the BoundBox API is not really needed.

in their declarations. Note that this convention was already used in
many places but not everywhere.

the advantage that the the spell checking utility skips these terms.
