Reduces the GLSL to MSL translation stage of shader compilation from 120 ms to 5 ms for complex EEVEE materials. This manifests in faster overall compilations, and faster cache hits for secondary compilations, as the MSL variant is needed as a key.
Startup time is also improved for both first-run and second-run. Note that this change does not affect shader compilation times within the Metal API.
Also disables shader output to disk

Replace texelFetch calls with a texture point-sample rather than a textureRead call. This increases texture cache utilisation when mixing between sampled calls and reads. Bounds checking can also be removed from these functions, reducing instruction count and branch divergence, as the sampler routine handles range clamping.

Test results were generated from incorrect code.
Code was fixed, but test results weren't updated.
This patch updates the test results to match the implementation.
- `projection_perspective.w.w == 0.0`
Also minor changes in comments:
- Reference BLENDER_HISTORY_FILE instead of the literal file-name

- Use usernames in tags, as noted in code-style.

Currently when importing a USD file, some of the camera properties are
ignored, or the units are not converted correctly from USD world units.
On import we currently set the focal length, but not the camera sensor
size (horizontal and vertical aperture), so the camera field of view
is wrong. The sensor size information is in the USD file, but is ignored
for perspective cameras.
USD uses "tenth of a world unit" scale for some physical camera properties
like focal length and aperture.
https://graphics.pixar.com/usd/release/api/class_usd_geom_camera.html#UsdGeom_CameraUnits
I have added the UsdStage's metersPerUnit parameter to the ImportSettings
so the camera can do the required conversion on import. This will convert from
the USD file's world units to millimeters for Blender's camera settings.

The glsl files + create infos of shaders that are only used

This isn't needed and shouldn't be included. This change will
only include them when WITH_GTEST and WITH_OPENGL_DRAW_TESTS are
enabled. All other cases those files will be skipped.
Resolve an issue where released buffers were returned to the reusable memory pool before GPU work associated with these buffers had been encoded. Usually release of memory pools is dependent on successful completion of GPU work via command buffer callbacks. However, if the pool refresh operation occurs between encoding of work and submission, buffer ref-count is prematurely decremented.
Patch also ensures safe buffer free lists are only flushed once a set number of buffers have been used. This reduces overhead of small and frequent flushes, without raising the memory ceiling significantly.

Compute test case still used legacy API to construct
GLSL shaders. This change will migrate it to use the
GPUShaderCreateInfo's.
In preparation to run test-cases against non-opengl
back-ends.
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.

Paths to vulkan libraries, paths and related components were
hardcoded in the platform cmake file. This patch separates
this by using adding CMake modules for Vulkan and ShaderC.
This change has only been applied to the macOs configuration as
that is currently our main platform for development. Other platforms
will be added during the development of the Vulkan back-end.
Metal backend does not support primtiive restart for point primtiives. Hence strip_restart_indices removes restart indices by swapping them to the end of the index buffer and reducing the length.
An edge-case existed where all indices within the index buffer were restarts and no valid swap-index would be found, resulting in a buffer underflow.

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.

When moving or linking an object to a collection, the report was not
properly translatable. In French for instance, it would give
nonsensical half-translated sentences such as "<Object> moved vers
<collection>", instead of "<Object> déplacé vers <collection>".
Instead, separate the report into the four possible translations (one
or multiple objects, linking or moving). This is very verbose and less
legible, but it ensure the sentences can be properly translated,
including plurals in languages which use grammatical agreement.
In addition, use BKE_collection_ui_name_get() to get the collection
name, because the Scene Collection's name is hardcoded, but it can be
localized.

This operator updates scene strip internal length to reflect target
scene length. Previously scene strip had to be deleted and added from
scratch. Scene strip length in timeline will not be changed.
The code removed here was intended to be an optimization that
avoids creating an additional node to join multiple attribute sets.
However, that optimization did not work, because it did not take
into account whether the single attribute set is required or not.
Allow to explicitly swap node links by pressing the alt-key while
reconnecting node links. This replaces the old auto-swapping based on
matching prefixes in socket names.
The new behavior works as follows:
* By default plugging links into already occupied (single input)
sockets will connect the dragged link and remove the existing one.
* Pressing the alt-key while dragging an existing node link from one
socket to another socket that is already connected will swap the
links' destinations.
* Pressing the alt-key while dragging a new node link into an already
linked socket will try to reconnect the existing links into another
socket of the same type and remove the links, if no matching socket
is found on the node. This is similar to the old auto-swapping.
Swapping links from or to multi input sockets is not supported.
This commit also makes the link drag tooltip better visible, when using
light themes by using the text theme color.

Most operations where strips are duplicated use `SEQ_animation` API,
which handles keyframe animation. Now drivers are handled as well.
When group of strips is duplicated and driver references other strip,
it will still reference original strip. However, this is much better,
than previous behavior, when strip duplication results in "transfer" of
driver from original strip to duplicated one.
