The memory manager includes both a GPUContext-local manager which allocates per-context resources such as Circular Scratch Buffers for temporary data such as uniform updates and resource staging, and a GPUContext-global memory manager which features a pooled memory allocator for efficient re-use of resources, to reduce CPU-overhead of frequent memory allocations.
These Memory Managers act as a simple interface for use by other Metal backend modules and to coordinate the lifetime of buffers, to ensure that GPU-resident resources are correctly tracked and freed when no longer in use.
Note: This also contains dependent DIFF changes from D15027, though these will be removed once D15027 lands.

This happened because of the false assumption that `std::array<char, 32>`
would be treated as a container and not relocate their content if the
`Vector` would grow. Replacing with actual object allocation fixes the
issue.
Candidate for 3.2.1 corrective release.
MTLFrameBuffer has been implemented to support creation of RenderCommandEncoders, along with supporting functionality in the Metal Context.
Optimisation stubs for GPU_framebuffer_bind_ext has been added, which enables specific assignment of attachment load-store ops at the bind level, rather than on a framebuffer object as a whole.
Begin and end frame markers are used to encapsulate frame boundaries for explicit workload submission. This is required for explicit APIs where implicit flushing of work does not occur.

This patch adds support for PBVH drawing in EEVEE.
Notes:
# PBVH_FACES only. For Multires we'll need an API to get/cache attributes. DynTopo support will be merged in later with sculpt-dev's DynTopo implementation.
# Supports vertex color and UV attributes only; other types can be added fairly easily though.
# Workbench only sends the active vertex color and UV layers to the GPU.
# Added a new draw engine API method, DRW_cdlayer_attr_aliases_add. Please review.
# The vertex format object is now stored in the pbvh.

This avoid leaving a `GPUMaterial` in a `GPU_MAT_QUEUED` state which would
block rendering.

After this commit, all mesh data extraction and drawing code is in C++,
including headers, making it possible to use improved types for future
performance improvements and simplifications.
The only non-trivial changes are in `draw_cache_impl_mesh.cc`,
where use of certain features and macros in C necessitated larger
changes.

full scaled image isn't used anymore. It was added to use a different scale when
displaying an image in the image editor. This was replaced by the image engine
redesign.
This change will reduce complexity of {T98375}.
This allows using the Graphic API to copy buffer data.
The GPU module do not expose untyped buffers even if that's what most API
do, so the copy function need to be strongly typed.
Contains GL backend implementation.
Since rB2a7a01b339ad, `lineSmooth` has lost its default value of true.
rBa0a99fb25284 only fixed the problem on master.
But thanks to @hitrpr for spotting the bug in version 3.2 too.

GLSL has different max number of ssbo per glsl stage.
This patch checks if the number of compute ssbo blocks matches
our requirements for the GPU Subdiv, before enabling it.
Some platforms allow more ssbo bindings then blocks per stage.

This is caused by the geometry shader used by the edit mode line drawing.
If the drawcall uses indexed drawing and if the index buffer only contains
restart indices, it seems the result is 1 glitchy invocation of the
geometry shader.
Workaround by tagging these special case index buffers and bypassing
their drawcall.
Viewports where cleared explicitly due to compatibility reasons with Intel iGPUs.
This slowed down other platforms as well, this wasn't noticeable on all platforms.
This patch will be more selective when to enable the workaround.
Currently only for iGPUs on Mac + Linux.
Some drivers completely forbid quote characters even in unused
preprocessor directives.
This patch adds a debug build check for all `.glsl` files that need to
be manually handled. For shared headers with `#include` directives, we
need to do runtime patching of the source to remove the quote.
Also fix an instance of the quotes check failing in `eevee_next`.
This was caused by the `Closure` members being added to the final contribution
more than once. The workaround is to clear the members once a closure has
been added to the final contribution. I used `inout` on `Closure` inputs
so that the render engine implementation of mix and add closure nodes
can do its own thing. The nodegraph handling of inout was changed for this
to work.
